  • Contributors to code can fork the github mirror repository and submit pull requests: the diff of the PR will be merged into SVN. Or contributors can still checkout from SVN and submit patches in issues as before.

1.55.0

  • fix issue 104 again, for recent TomEE versions (thanks to Frederic Cornuau)
  • fix issue 436: implement Servlet 3.1 new methods (JavaEE 7), in FilterServletOutputStream and others

1.54.0

  • fix issue 440: Not able to start Desktop version.
  • fix broken link to the ehcache documentation (revision 3972)
  • fix: In the Jenkins plugin, the monitoring reports of a slave didn't work if its name contains a space.

  • improved: In the optional collect server, upgrade the embedded Winstone server.

1.53.0

  • fix: XSS vulnerability in the reports
  • fix: in v1.52.0 with Tomcat, graphs of bytes received/sent and of Tomcat active threads were not displayed anymore in "Other charts" (revision 3908). This was unfortunately caused by the fix of issue 406.

  • added: new parameter "authorized-users" for BASIC authentication with username and password to access the reports in the monitored webapp or in the optional collect server (revision 3890, revision 3914, thanks to Benjamin Durand).

If you want BASIC auth but do no want to use a realm and "security-constraint" in web.xml, you can add the parameter "authorized-users" in web.xml, in context or in system properties like the other javamelody parameters. For example in your WEB-INF/web.xml file:

	<filter>
		<filter-name>javamelody</filter-name>
		<filter-class>net.bull.javamelody.MonitoringFilter</filter-class>
		<init-param>
			<param-name>authorized-users</param-name>
			<param-value>user1:pwd1, user2:pwd2</param-value>
		</init-param>
	</filter>
	...

1.52.0

  • fix issue 406: Slow GUI with JBoss EAP 6.2 (only since 6.2)
  • fix issue 415: Periodic stack trace in Tomcat 8 logs 'java.lang.IllegalStateException: The resources may not be accessed if they are not currently started'
  • fix issue 423: Link to DataSource Reference Returns HTTP 404
  • fix in the Liferay plugin, the monitoring page works after deploy, but is not found (404) after restart of Liferay (commit 78618d3). This was caused by interaction between web-fragment.xml and Tomcat 7 inside Liferay.
  • fix issue 377: in JIRA, Confluence: Incorrect Installation Instructions on Atlassian Marketplace
  • improved: reduce the number of RRD files created in some conditions, by not creating a RRD file of mean times if a request is called only once (revision 3836). Otherwise, obsolete RRD files are automatically deleted after 3 months like before.
  • added: links "View in a new page" below the tables of threads and of current requests (revision 3839). For example when the app is under load, the new pages make it easy to refresh at will the details of threads or of the current requests to see if states change or not, without refreshing all the main page.
  • added: logout action in the menu on the right of the main report, if there is a http session (revision 3859)
  • In the Jenkins monitoring plugin, upgraded mininum Jenkins version to 1.509.3
  • added: In the Jenkins monitoring plugin, display of build steps and their durations, in the detail of each build statistics in the "/monitoring/nodes" page. See Example

  • fix "ORA-00911: invalid character", when using the sql-transform-pattern parameter, for the display of the explain plan of some sql requests (Oracle database only, revision 3799)
  • Drop Java 5 support. Said otherwise, a JDK or a JRE v1.6 or later is needed for javamelody v1.51 or later. For Java 5, previous versions of javamelody can still be used. (revision 3795)
  • Optimized desktop UI startup time, by downloading desktop app and caching locally (revision 3762)
  • improved: abstract very long sql requests (issue 403)
  • improved: in a graph detail, a checkbox can now hide maximum values in the graph, so that average values are better displayed when much lower than the maximum (issue 368)
  • added: PID in the heap dump file name (revision 3773)

1.50.0

  • JavaMelody license changed from LGPL to ASL, as discussed here: https://groups.google.com/forum/#!topic/javamelody/JI3yNH0Xmb0/discussion (revision 3649)

  • Downloads moved to GitHub

  • fix issue 370: work around ConcurrentModificationException during Tomcat startup (which is a Tomcat bug)

  • fix issue 378: Slf4j system, with log4j-over-slf4j, is not detected with version 1.7.6 of slf4j (thanks to jgraglia)

  • fix compatibility of jdbc datasource monitoring with WildFly (revision 3686)

  • fix issue 386: IllegalArgumentException: No enum const class ..., in Turkish

  • fix: In the JIRA/Confluence/Bamboo plugin, fix compatibility with some old Confluence versions, such as 3.5.13 (revision 3640)

  • fix from grails PR 17: In the JavaMelody Grails plugin, verifying that property exists using hasProperty (thanks to stiancor)

  • fix from grails PR 16: In the JavaMelody Grails plugin, getting the disabled property from the grails javamelody config when running test-app (thanks to stiancor)

  • fix: the optional collector server may stop collecting in case of errors in notifications (revision 3703)

  • improved: In the US, depending on the browser's language or on the javamelody parameter "locale", the paper size is now Letter in the US, instead of A4 like in the other countries. (revision 3679, thanks to Dennis)

  • improved css styles: font finally fixed to Arial/Helvetica (revision 3718). Note: You can customize styles and other resources.

  • added: Menu. A floating button is available on the right of the main report to drag a menu in or out. The menu displays the list of chapters in the report and allows to jump easily between them (revision 3705).

  • added: Custom reports. You can now include links to your custom reports in the floating menu described above. For that, add a parameter named "custom-reports" like the other javamelody parameters. In the value of this parameter, put the list of names of your custom reports separated with commas. Then for each custom report, add a parameter with the same name and its path as value. For example:

		<init-param>
			<param-name>custom-reports</param-name>
			<param-value>Send feedback,My custom report</param-value>
		</init-param>
		<init-param>
			<param-name>Send feedback</param-name>
			<param-value>https://groups.google.com/forum/#!forum/javamelody</param-value>
		</init-param>
		<init-param>
			<param-name>My custom report</param-name>
			<param-value>/WEB-INF/pages/myCustomReport.jsp</param-value>
		</init-param>

If the path starts with '/', it will be considered as a JSP (or a servlet) inside the webapp. Otherwise it will be considered as an URL (http://example.com). As example of JSP, you can add the file "/WEB-INF/pages/myCustomReport.jsp" in your webapp, with a content like this one. This example can be seen in the demo.

If you use JPA with a persistence.xml file, you can now monitor main calls on the JPA EntityManager (since v1.50).

To enable the JPA monitoring with JPA statistics in the report, set net.bull.javamelody.JpaPersistence as JPA Provider in your persistence.xml file. For example:

	<?xml version="1.0" encoding="UTF-8"?>
	<persistence version="2.0"
				xmlns="http://java.sun.com/xml/ns/persistence"
				xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
				xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
				http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
		<persistence-unit name="my-unit">
			<provider>net.bull.javamelody.JpaPersistence</provider>
			...
		</persistence-unit>
	</persistence>

If you have in your environment a single "real" JPA provider it should be found automatically. But if that's not the case of if you want to force the implementation set the property net.bull.javamelody.jpa.provider to the real implementation you want. For example:

	<?xml version="1.0" encoding="UTF-8"?>
	<persistence version="2.0"
				xmlns="http://java.sun.com/xml/ns/persistence"
				xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
				xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
				http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
		<persistence-unit name="my-unit">
			<provider>net.bull.javamelody.JpaPersistence</provider>
			<properties>
				<property name="net.bull.javamelody.jpa.provider" value="org.hibernate.jpa.HibernatePersistenceProvider" />
				...
			</properties>
			...
		</persistence-unit>
	</persistence>

  • added: MonitoringTargetInterceptor as an alternative to MonitoringInterceptor for EJB monitoring
  • added: detect cpu hotspots (issue 149, with some ideas from Cédric Lime).

In the monitoring reports, the new Hotspots screen displays CPU hotspots in executed methods for all the JVM. Like javamelody, the overhead of hotspots is low: it is based on sampling of stack-traces of threads, without instrumentation. And like javamelody, it is made to be always active if enabled. (It is currently not enabled by default. It may be enabled by default in the future.) Two parameters can be defined in web.xml, in context or in system properties like the other javamelody parameters:

  • "sampling-seconds" to enable the sampling and to define its period. A period of 10 seconds can be recommended to have the lowest overhead, but then a few hours may be needed to have significant results for a webapp under real use. If you don't mind having a bit more overhead or want a result faster in test, you can use a value of 1 or 0.1 in second for this parameter.
  • "sampling-excluded-packages" to change the list of the excluded packages ("java,sun,com.sun,javax,org.apache,org.hibernate,oracle,org.postgresql,org.eclipse" by default)

  • added: When using the optional collect server, enable use of http Basic authentication to secure access to the monitored webapp, for example when the ip-address of the collect server is not known upfront (issue 214, thanks to purnhar). Documentation is here.
  • added: When using the optional collect server, the size of the stream, between the monitored webapp and the collect server, is now written in the log of the collect server for each call. (Note that the stream is compressed if more than 50 KB ; when compressed, the log gives the compressed size. revision 2828)

  • fix issue 178: In the Jenkins/Hudson plugin and in JIRA/Confluence/Bamboo plugin, since v1.32, "Nb of http sessions" is 0 and "View http sessions" is always empty.
  • fix JNDI error in the vFabric server (revision 2540)
  • added: In the Jenkins/Hudson plugin, new graphic of "Build queue length" in the monitoring of nodes, next to the graphic of "Running builds" (revision 2515, done in Jenkins Hackathon, with help from Kohsuke Kawaguchi)
  • added: some "database reports" for DB2, in the "System information" part: MON_CURRENT_SQL, MON_DB_SUMMARY, MON_LOCKWAITS, MON_SERVICE_SUBCLASS_SUMMARY, MON_CURRENT_UOW, MON_WORKLOAD_SUMMARY, MON_GET_CONNECTION and fix of SNAPSHOT_DYN_SQL (issue 179, thanks to Peter James and his DBA from humanservices.gov.au)
  • added: optional parameter (dns-lookups-disabled) to allow disabling of dns lookups with InetAddress.getLocalHost() to prevent long hangs on startup/shutdown in some particular environments (issue 181, thanks to r6squeegee)
  • added: In the Grails Melody plugin, read the configuration parameters from both Config.groovy and GrailsMelodyConfig.groovy (issue 180, thanks to padcom)
  • added: possibility to customize "name" in the statistics (long standing issue 31). Note that instance creation (such as String concatenation) must be reduced to the minimum, otherwise there will be a performance overhead. It is really not recommended to customize.

1.34.0

  • fix issue 121 and issue 175: Incompatibility with Quartz 2 (thanks to rogerc at costumercentrix.com)
  • fix issue 164: JBoss 7 support for SQL monitoring with JNDI datasource (thanks to sarnowski at new-thoughts.org)
  • fix issue 166: jboss-as-client and javamelody log4j conflict (java.lang.IncompatibleClassChangeError)
  • fix issue 170: Plugin for JIRA / Confluence / Bamboo: Compatibility with JIRA 5.0 RC
  • fix: if the http request contains for example ";jsessionid=1234567890ABCDEF", when the browser does not accept cookies, then that part is automatically ignored for the statistics (revision 2363)
  • fix fonts in the PDF reports for Chinese people, when the first PDF report was made for non Chinese people (revision 2441)
  • added: graphic over time of the "Transactions per minute" in "Other charts" of the reports. This graphic is similar to "Http hits per minute" and to "Sql hits per minute", but for database(s) transactions (more precisely, for the number of opened jdbc connections per minute). The values in this graphic are typically about one tenth of the values in "Sql hits per minute", depending on the mean number of sql requests per transaction in the monitored application (revision 2467).

Maven central repository

The latest release of javamelody artifacts are now available in the Maven central repository: javamelody-core in central . And so, you don't need anymore to use in your pom.xml or settings.xml the http://maven.glassfish.org repository for javamelody.

(In fact, it seems that some obsolete artefacts of javamelody were recently published by Sonatype in Maven central from an old java.net repository. Seeing that, I published the latest javamelody artefacts in Maven central.)

1.33.0

  • fix issue 146 and issue 153: Incorrect Struts statistics when two actions have the same name but are in different packages. Note: the consequence is that the names of all the Struts actions are changed in the statistics.
  • fix issue 152: Error with execution plan for "ALTER SESSION..."
  • fix issue 157: In the Grails plugin, do not add groovy meta programming on services if javamelody is disabled. (rev 76158)
  • fix Jenkins issue 11293: Monitoring plugin not installed because of NoClassDefFoundError: org.slf4j.ILoggerFactory on IBM J9 JVM (rev 40073)
  • fix: When using the collect server and if Oracle database, display the execution plan in the detail of a sql request like when the collect server is not used (revision 2305).
  • fix issue 160: Disabling sql statistics with the "displayed-counters" parameter should not disable the connection monitoring
  • added for issue 158: note in the UI and in the online help to say that since ehcache v2.1, the cache statistics need to be enabled in order to display efficiency values
  • added: JSF actions statistics like for Struts 2 actions. If the application to monitor contains some JSF actions based on Mojarra (JSF Reference Implementation), a counter is automatically created for statistics of execution of actions. A JSF ActionListener is automatically added for the JSF application and you don't need to do anything to have JSF statistics.

1.32.1

  • fix issue 151: a Java 1.6 dependency was introduced in 1.32.0 (NoSuchFieldError: ROOT)

1.32.0

  • Major change: System actions are now enabled by default, including in the centralized collect server, because they are useful. If you want to disable them, as it was before by default, then you can add a system-actions-enabled parameter with value false: see the user guide or add a system property -Djavamelody.system-actions-enabled=false (revision 2202).
  • fix issue 137: MonitoringInterceptor when Stateful EJB, Java EE 6
  • fix issue 141: exception while collecting data java.io.IOException: Read failed, file xyz not mapped for I/O (after out of disk space)
  • fix issue 147: When the monitoring filter is incorrectly defined in web.xml for recent appserver, parameters inside filter are sometimes ignored
  • fix: In the collector server, refuse to add twice one instance of an application (for example, individually and then in a cluster), because it would not work (revision 2157).
  • added: Chinese translation, and fix display of Chinese characters in the JRobin graphics and in the PDF reports (issue 150)
  • added: Action "Generate a heap dump" added for IBM JDK like for Oracle JDK, patch by David Karlsen in the users' group (revision 2180)
  • added: Add link "Dump threads as text" below the list of threads (revision 2163 and revision 2196)
  • added: Provide an url to test sending a pdf report by mail (issue 145)

1.31.0

  • fix issue 128: Fix the shutdown process in JIRA 4.3.4 and clean it for Confluence/Bamboo/Jenkins/Hudson.

  • fix issue 129: ArrayIndexOutOfBoundsException in GWTRequestWrapper in a particular case.

  • fix issue 134: In JBoss, sending mails with weekly report should not need jboss-web.xml

  • issue 133: Documentation added on OSGI configuration when using JBoss AS 7

  • To display the username in the list of http sessions, look at ACEGI_SECURITY_LAST_USERNAME and SPRING_SECURITY_LAST_USERNAME if getRemoteUser() was null (In particular, for Jenkins/Hudson. Revision 2003).

  • The JRobin dependency is now available in the maven glassfish repository as JavaMelody: http://maven.glassfish.org/content/groups/public/org/jrobin/jrobin/1.5.9/. So it is not necessary to add the jrobin repository or the jrobin dependency in your pom.xml. The jrobin dependency is included transitively with javamelody-core. Reference: UserGuide#Dependencies

1.30.0

  • fix issue 116: MBeans overview does not work with java 1.5
  • fix issue 117: Sorting of numbers is based on String comparison in German
  • fix issue 122: Average number of requests per minutes seems to be wrong, with a single day in a custom period
  • fix issue 124: Start date removed from the text at the top of the monitoring page, except if the "All" period is selected.

1.29.0

  • fix issue 106: a few HTTP hits are lost in the statistics for the first hit(s) on new requests (no impact on statistics once requests are known)
  • fix issue 104: support SQL monitoring in Apache OpenEJB bundled as TomEE
  • fix issue 107: Hibernate factory doesn't work with HSQL with batching turned off
  • fix issue 108: async-supported added in the web-fragment.xml file to support asynchronous requests in Tomcat 7.0.
  • added: PDF report for the "Summary by class"

1.28.0

1.27.0

  • fix issue 97: StackOverflowError in JBoss 4 when using JNDI dataSources with several monitored webapps (fix verified by Saurabh Arora).
  • grammar fixes in English user guides and online help by Stéphanie Bourbon
  • added: pdf report of "Runtime dependencies" for EJB3/Spring/Guice/Services (needs the iText jar dependency)
  • added: pdf report of MBeans (system actions must be enabled)
  • added: SpringDataSourceFactoryBean, as an alternative to excludedDatasources in SpringDataSourceBeanPostProcessor, in order to define which datasources are monitored (issue 90, patch by David Karlsen)
  • JavaMelody Grails Plugin: use dependency resolution (issue 92).
    Dependencies of the plugin are now declared in BuildConfig.groovy instead of jar files in the plugin. As a consequence and starting from JavaMelody Grails plugin v1.2, a network connection will be needed the first time to download the dependencies with Ivy.

1.26.0

  • added: GWT-RPC detailed statistic collection feature, contributed by dhartford (issue 88).
    Breaks up general servlet calls (GwtServiceServlet) into the specific GWT-RPC calls for statistic collection (GwtServiceServlet.LOGIN GWT-RPC, GwtServiceServlet.Data_retrieve_method GWT-RPC, GwtServiceServlet.update_data GWT-RPC, etc).
    Only enabled when GWT-RPC is detected (and 'http'). Works with GWT 1.3 to 2.1 (to date). Will not work with deRPC/RequestFactory transport mechanisms, only GWT-RPC specifically.
  • added: Portuguese Brazil translation, including the online help, thanks to Luiz Gonzaga da Mata and Renan Oliveira da Cunha. This translation is the default for all Portuguese people. The first language in the browser settings should be Portuguese (pt) or Portuguese/Brazil (pt-br) to use it. The online help in Portuguese Brazil is also available.
  • fix issue 85: web-fragment schema location in JBoss 6.0.0 CE, patch contributed by dhartford
  • fix JNDI report in Glassfish, WebLogic, Jonas and Websphere
  • fix issue 89: Listing of MBeans fails in Jetty

    • added: in the nodes report, chart of the number of the running builds by period

1.25.0

  • fix: When the spring context is initialized before the web filter of the monitoring and when "displayed-counters" is not used, the spring monitoring was not displayed (Pete in the users group).
  • fix some issues in the monitoring of Hudson nodes when the operating systems of the nodes are heterogeneous
  • fix issue 36: Grails Melody plugin blocks closure (fixed by Jean Barmash and Liu Chao)
  • fix issue 79: Spring security core integration for the Grails Melody plugin (fixed by Liu Chao)
  • fix issue 80: Memory histogram should be supported on Mac OS X
  • fix issue 83: StringIndexOutOfBoundsException for caches with # in the name of a cache
  • added: graphic of the mean age of the currently valid http sessions (in minutes), displayed in the "Other charts"
  • added: if JRockit, display the JRockit specific MBeans
  • added: pdf reports of http sessions and of heap histogram
  • This time the artifacts are published in the usual maven repository.

1.24.0

  • fix issue 67: EhCache 1.4.x detection is not robust enough (NoClassDefFoundError)

  • fix issue 68: support more prefixes for JNDI names of datasources

  • fix issue 69: NullPointerException when getting resources if mime-type is null

  • fix issue 71: StringIndexOutOfBoundsException with # in JVM parameters

  • fix issue 73: / by zero when max_elements_in_memory = 0 in ehcache

  • fix issue 74: "View OS Processes" does not work on MAC OS X Server

  • fix issue 75: StringIndexOutOfBoundsException for http session with # in attributes

  • added: in the optional collect server, "add and remove applications" can be restricted (issue 61)

  • added an enhancement on jdbc proxy: Improve JDBC connection wrapper equals invocation when args[0] is a javamelody proxy (issue 78)

  • added: In the system actions, new view "MBeans" with the values and the descriptions of the attributes. (MBeans contain configuration and low-level data on the application server and on the JVM). The values are viewable but not writable and operations can not be performed.

  • added for Munin/Nagios: for each MBean attribute, a link on the left of the attribute is provided to have only the current value of an attribute in plain text. And a link below zoomed graphics is also provided to have only the last value in the graphic. For example, the following URLs can be used in this version: 1 and 2. (To use the url for a MBean value, the system actions must be enabled).
    This feature can probably be used to write a Munin/Nagios plugin using something like this in order to have in Munin the same graphics as in JavaMelody or to have some new graphics based on MBeans values.

  • added in the Hudson Monitoring plugin: Monitoring of the Hudson nodes (slaves in general) similar to the monitoring of the Hudson master.
    If the monitoring of the Hudson master is available at http://localhost:8080/monitoring then the monitoring of the Hudson nodes is available at http://localhost:8080/monitoring/nodes.

    The monitoring of the Hudson nodes includes:

    • Aggregated "used memory" chart, aggregated "% cpu" chart (between 0 and 100) for day, week, month, year or a custom period.
    • Chart of the build times over time for the selected period
    • Other aggregated charts: % GC, threads count, loaded classes count, system load average, open file descriptors count and more for the selected period
    • Statistics of the build times for the selected period
    • Running builds with time elapsed
    • Threads informations for each node including name, state, stack-trace and an action to kill any thread
    • Heap histogram aggregated for all nodes
    • Current system informations for each node
    • MBeans for each node
    • Last values in charts and MBeans values like above. For example, the following URLs can be used: 1 and 2
    • Process informations for each node
    • Actions to execute the GC or to generate a heap dump on each node
  • Due to the current infrastructure changes for the maven2-repository in java.net:

    • The Monitoring plugin 1.24.0 for Hudson can be downloaded from http://javamelody.googlecode.com/files/monitoring.hpi
      You can submit this hpi file in the Advanced tab of the plugin manager in Hudson and restart the server.
    • The jar file javamelody-core 1.24.0 is not published in any maven repository.
    • A new release will probably be made when the maven2-repository comes back.

1.23.0

  • fix issue 66: Since tomcat 6.0.21 and when tomcat based authentication is used, session count is false and there is a possible memory leak for invalidated http sessions. This is because of the changes for tomcat enhancement 45255. To tomcat experts: Isn't an http session supposed to die first before being able to born a second time? (Update: see 51042)

  • minor change in the gzip compression of the reports in order to fix the compatibility issue between the javamelody grails plugin and the UiPerformance grails plugin.

  • The "Monitoring" plugin can be installed by point and click in the plugin manager of a Hudson server, or it can be downloaded from http://download.hudson-labs.org/plugins/monitoring/. The plugin manager says that it is built for Hudson 1.388, but in fact it works for older versions of Hudson.

1.22.0

  • fix issue 54: v1.21.0 requires jdk 1.6, when "displayed-counters" is used
  • fix issue 58: Quartz in Spring and server shutdown. (Added parameter "quartz-default-listener-disabled" to be used for Quartz jobs only when used in Spring. See doc.)
  • fix issue 59: Maximum values in statistics can be incorrect
  • fix issue 62: IndexOutOfBounds for report on some jobs
  • added major feature for Hudson and Jira/Confluence/Bamboo plugins: graphic of the number of sessions and details on http sessions with the link in "System informations" (this is emulated without httpsessionlistener, because httpsessionlistener can't be used in Hudson plugins or in Atlassian plugins)
  • added: @MonitoredWithSpring can be added on interfaces like on implementation classes. See doc.
  • added: the system property -Djavamelody.plugin-authentication-disabled=true can be added to a Hudson, JIRA, Confluence or Bamboo server in order to disable authentication of the monitoring page in the javamelody plugin and to be able to add the server to a centralized collect server. See doc. (A system property like -Djavamelody.allowed-addr-pattern=127.0.0.1 can also be added with the ip address of the collect server)
  • removed: because parameters in environment variables can't work well in all OS, the possibility to use environment variables is removed. Use this instead.

1.21.0

  • fix issue 48: Quartz errors for persistent jobs after jobs' classes are renamed or deleted
  • fix to display the list of http sessions when Tomcat throws an exception "Session already invalidated"
  • fix to display the list of process when using Windows in Germany
  • added: If Tomcat or JBoss, new graphics in "Other charts" for the number of active http and ajp threads in all the server, the number of bytes received per minute and the number of bytes sent per minute by the server (the number of bytes received is often 0 for most webapps).
  • New view with the summary per class of statistics for EJB/Spring/Guice/services with aggregation for methods and another view for the methods of the selected class.
  • enhanced documentation on the configuration of the optional centralization server such as to enable system actions or to send daily/weekly/monthly reports by mail.

Grails Plugin 0.5

JavaMelody Grails Plugin 0.5 has been released.

  • includes JavaMelody 1.20.0
  • Grails version was updated to 1.2.4 in the plugin, only to be able to release the plugin
  • issue 36 is a known open issue for the plugin when a closure is used in a service (contribution welcome)

1.20.0

  • added: German translation thanks to Ewald Arnold. We would like to have feedback here.
  • added: Documentation on using JavaMelody with a maven dependency
  • fix: In the html display of the current requests, put back the complete http request with query parameters and values, like it was displayed before v1.16.0
  • fix issue 45: Optimization of html rendering when there are thousands of threads or current requests: the threads are displayed in their own page when there are more than 500 threads, and the "current requests" are also displayed in their own page when there are more than 500 of them. If there are less than 500 threads or current requests, then nothing is changed in the reports.
  • Note that a webapp with JavaMelody has no problem with 7000 threads and 7000 active http requests ! and that html reports are already highly compressed in this case.
  • For the same optimization reason, when the optional centralized collect server is used, the data from the monitored application to the collect server are now compressed when the size of the stream is larger than 50 KB (for example, when there are 7000 threads). This applies when the transport format is 'serialized' but also when it is 'xml' (or 'json').

1.19.0

  • fix issue 38: Distributed (XA) Transactions aborted by 'rollback' in JavaInformations.java
  • fix issue 41: NumberFormatException requesting process information
  • fix issue 44: Sql requests not monitored when using jdk1.6, a recent jdbc driver and net.bull.javamelody.JdbcDriver
  • added: Alternative for sql requests monitoring when jdbc datasource or jdbc driver can't be used and when Hibernate is used: HibernateBatcherFactory
  • Logs for debugging added using either logback if found, or log4j if found or java.util.logging, and using the category "net.bull.javamelody" and the level "debug". Moreover, existing stack-traces of exceptions are no longer printed in the error console of the server, and they are now logged in logback or log4j or java.util.logging, using the category "net.bull.javamelody" and the level "info" or "warn". Logging of http requests is unchanged.
  • added: Names of MonitoringProxies can now be customized.
  • added: Documentation on the javamelody parameter no-database
  • added: Documentation on the report written before the last shutdown

1.18.0

  • fix issue 33: Database name or jdbc driver with '#' causes IndexOutOfBounds
  • fix issue 34: Application server restart causes persistent Quartz jobs to be hanging around
  • added: "JNDI Tree" link in "system actions" (for example to check if a datasource is really in "java:/" or in "java:/comp/env/")
  • install note for bamboo 2.6: see end of issue 37

Grails Plugin 0.4

JavaMelody Grails Plugin 0.4 has been released by Liu Chao.

  • includes JavaMelody 1.17.0, in particular for Quartz jobs

1.17.0

  • fix issue 28: NoSuchMethodError when undeployed and when JavaMelody 1.15.0 or 1.16.0 is used with Quartz 1.7 or 1.8
  • fix issue 30: Quartz job CRON expression with '#' causes NullPointerException
  • fix for Grails: an exception in initialisation of Quartz should not stop initialisation of the webapp
  • fix issue 8: A synchronized (rrdDb) was added against the exception "Bad sample timestamp x. Last update time was x, at least one second step is required". It was seen with deployment on Tomcat without modification of monitored webapps.
  • fix for JIRA: "mean sql hits" and "mean sql time" displayed in http and in jsp statistics
  • changed: The default order of MonitoringSpringAdvisor is now 0 for priority before other spring advisors (issue 32)
  • added: Statistics of Struts 2 actions
  • added: If Oracle database and if system actions are enabled, 3 new reports on foreign keys without indexes, invalid objets and disabled constraints

1.16.0

  • Compatibility of the JIRA/Bamboo plugin with Confluence
    • Notes: The "Monitoring" link is moved to the Administration menu and only administrators in JIRA/Bamboo/Confluence are authorized to view reports. Http sessions are unfortunately never seen by this plugin.
  • Monitoring of jdbc connections and of sql requests in JIRA (and in Confluence and Bamboo if a jdbc datasource is used and not a direct jdbc connection)
  • Fix issue 26: In JIRA, the count of used jdbc connections increases in the display with each "/monitoring" page refresh (but connections are really closed)
  • added: Monitoring of Business facades with Guice (like with EJB or with Spring)
  • Some minor bugs fixed

JavaMelody Grails Plugin 0.3

JavaMelody Grails Plugin 0.3 has been released by Liu Chao.

  • fix issue 18: Grails-melody plugin breaks the filterpane plugin
  • includes JavaMelody 1.15.0

1.15.1 of Hudson plugin and of JIRA/Bamboo plugin

  • JIRA/Bamboo plugin

    • fix issue 24: StackOverflow when a SSO plugin with seraph is used
    • jdbc connections and sql requests are now monitored in JIRA (like jsp pages)
  • Hudson plugin

    • change to reduce disk usage: Some common http requests are now aggregated in statistics, for example on build numbers. The javamelody.http-transform-pattern parameter has now the default value of "/\d+/|/site/.+|avadoc/.+|/ws/.+|obertura/.+|estReport/.+|iolations/file/.+|/user/.+|/static/\w+/" and all matches in http URLs will be replaced by "$". Note that it is possible on each Hudson server to change the value of this parameter with a system property -Djavamelody.http-transform-pattern=xxx in the java command line.

1.15.0

  • fix issue 20: SQL requests were not monitored and "jdbc connections" were always 0, when JndiObjectFactoryBean is used in Spring
  • fix issue 21 for JIRA: Null pointer with quartz jobs in jira
  • fix issue 22 for JIRA: The report will be visible only for jira administrators
  • fix issue 23 for JIRA: The report displayed only random characters when gzip compression is enabled in jira
  • doc updated for quartz jobs scheduled with Spring, with help from Pether Sörling.
  • doc updated for issue 19 InternalError "Can't connect to window server" on Mac OS X Server.
  • doc updated for usage of JavaMelody when SecurityManager is enabled
  • added: Statistics of rendering times in JSP pages (when RequestDispacher is used)
  • added: If quartz is available, display of mean time and last error with stack-trace per job for the selected period, and also display of the statistics for all the jobs with number of executions, mean cpu times, number of sql hits, sql times and last 100 errors with stack-traces for the selected period.
  • added: In Hudson plugin, if the server has servlet api 3.0 (JavaEE 6), then display the graphic of the number of http sessions and display the list of current http sessions
  • change: the graphics and the statistics of ejb, spring and services will be displayed automatically when they are used (except if the parameter "displayed-counters" has been defined AND if the parameter does not include "ejb", "spring" or "services"). So usage of ejb, spring or services will be easier because it will not be necessary anymore to define the parameter "displayed-counters".
  • change to reduce disk usage: graphics for "http system errors" and "system errors logs" are no longer displayed (unneeded files will be automatically deleted at midnight)

1.14.0

  • fix: Use spring datasources in some parts of the reports, if of course the monitoring-spring.xml file (with the post-processor) is used as said in the user guide. Like with jndi datasources, database version and jdbc driver version will be displayed. And if system actions are enabled, reports on the database will be available (like mysql variables and process list, or oracle long requests).
  • fix issue 16: InternalError "Unable to open directory /proc/self/fd" on ubuntu or debian using the tomcat package with jsvc
  • fix in the javamelody plugin for atlassian (jira, bamboo, confluence): better aggregation of http URLs and less memory overhead in jira and in bamboo (the parameter "http-transform-pattern" has been changed in the atlassian plugin from "-\d+" to "-\d+|chment/.+|onent/.+|est/.+|ifact/.+" for attachment, component, test, artifact)
  • added with help from Pether Sörling: If Logback is available, warn logs are automatically monitored in order to display them in reports like with log4j and with java.util.logging, and Logback is used for log of http requests.
  • added: if system actions are enabled, display of stack traces of where were opened jdbc connections, in order to help find jdbc connection leaks

Atlassian JIRA and Bamboo plugin has been published on Atlassian plugin exchange: https://plugins.atlassian.com/plugin/details/20909

1.13.0

  • fix issue 14: html reports in utf-8 for cyrillic and other characters
  • fix issue 15: support for log4j-over-slf4j
  • added: remember the last selected period (with a persistent cookie in the browser)
  • added: UI option to display graphs and statistics for custom periods, via fields of start and end dates of period to display (from user group)

1.12.0

  • if a centralized collect server is used:
    • fix issue 12: workaround for a bug in Winstone (standalone mode)

  • added: If Oracle database, display of sql execution plan in sql request detail (seems not doable if postgresql or mysql, without particular parameter values)
  • added: New charts "Threads count", "Loaded classes count", "Used non heap memory", "Used physical memory", "Used swap space" (displayed with the new link "Other charts")
  • added: spring post-processor in net/bull/javamelody/monitoring-spring.xml to auto-detect datasources defined in a spring xml file.

  • added: New parameter monitoring-path to change the url "/monitoring" of the report to "/admin/monitoring" for example (from user group)

Atlassian JIRA plugin

A beta version of a JIRA plugin is released now to integrate JavaMelody in Atlassian JIRA. See UserGuide for installation.

This plugin has been tested with a JIRA 4.0.1 server, but it certainly works with Confluence and Bamboo.

1.11.1

  • fix for AssertionError in sql counter when assertions are enabled (in maven surefire for example)
  • if a centralized collect server is used:
    • fix: after an action like GC is called do not execute the action again and again when the page is refreshed with the action parameter in the url
    • added: display of a message to say what was done after an action is called
  • added: in sql or spring or ejb request detail, link to display the reversed call-tree (i.e. usages) of the request
  • added: parameters can now be specified in environment variables like in system properties, webapp context or as init-param of MonitoringFilter
  • added: if postgresql, display of pg_locks, pg_tablespace, pg_database and of cachehitratio in pg_stat_database
  • added: if ehcache, an action is available to clear all caches of all cache managers
  • added: extraction of "maxActive" and other properties from apache dbcp BasicDataSource like what is already extracted from apache tomcat BasicDataSource (as discussed in user group)
  • added: new parameter "mail-periods" to change the period of mail reports from weekly to daily or monthly or a combination of the 3 (as suggested in user group)
  • added: display the version of JavaMelody at the bottom of the html and pdf reports (as suggested in user group)
  • added: documentation to use JavaMelody in JonAS 5
  • added: display of "ajax GET" or "ajax POST" in http requests names for ajax requests (same as of version 1.11.0 except for a java assertion which has no impact in general)

Grails Melody plugin

A Grails Melody plugin was released by Liu Chao at http://www.grails.org/plugin/grails-melody to integrate JavaMelody in Grails (Groovy on rails).

1.10.0
