accessLogGetPOSTQueryString

what For ?

The situation is simple : you want to monitor, lookup, grab datas for data exploration/data science what is happenning on your Tomcat servers : by using this simple java code : you can keep trace of all GET and POST requests string parameters by overring the standard ACCESS LOG machanism explain in Tomcat doc : https://tomcat.apache.org/tomcat-9.0-doc/logging.html#Access_logging

summary

This simple java tomcat servlet filter is designed to allow write to standard access log (only strings) parameters from GET and POST requests.

This projet was first designed to catch requests sent to ESRI ArcGIS Server /arcgis/ WebAdaptor (which is a simple Tomcat webapp) to inject them to No SQL database (Elastic Stack including Logstash > ElasticSearch / Kibana)

QuickStart (classic and Docker)

You have all resources to deploy on Tomcat 9 AND Docker :

All files are in ./quickStart/ folder

Docker deployement (5 minutes setup !) :

All the files are in ./quickStart/ folder :

on a host machine with docker installed : run the bash script : ./build-image.sh
next call the script : ./spawn-ags-container.sh you have a output like this :

NErDy:quickStart odevarc$ ./spawn-ags-container.sh
clean the container $CONTAINER_NAME
testTomcat9
testTomcat9
TOMCAT_FOLDER_ROOT
odevarc.net
user for path creation is : odevarc
¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤  START  ¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤

	Script parameters are : testTomcat9 80 true

	CONTAINER_NAME is testTomcat9
	EXTERNAL_PORT for Tomcat port is 80
	CREATE_FOLDER_MAPPING is true

	Defining folder path to put volumes folders which ones MUST not exist otherwise container content will be replaced by local host folder content


	Create the network odevarc.net only if it does not exist

	Create specific network to allow all containers to communicate :


55d05e051bf28af575d01fe378133ca4766d712fb68753ab9c9817a7790c27d0


	Subnet for new network odevarc.net is :
	172.19.0.0/16


	Create the new container testTomcat9 from the image with binding in folder /Users/odevarc/docker-prod/volumes/tomcat-9/directories/80
19bd91f803a37972af8d3722ef0b6f91fe6c61f6dc38fa5f5124a4d22495bdc9
	On Linux (not on Mac OSX) you can view Tomcat Catalina home folder in :

/var/lib/docker/volumes/TOMCAT_FOLDER_ROOT/_data
You can come back to this point by typing : cd /Users/odevarc/Dropbox/Work/Programmation/Java/accessLogGetPOSTQueryString/quickStart


	Waiting 20 seconds until Tomcat is starting ...


	Check that Tomcat is UP AND RUNING

Updating server.xml file

	Put the python script to update the server.xml file container :


	Put the hostname in Catalina start script /bin/catalina.sh so the accesslog file have the hostname in filename:


	Restart Tomcat to activate GET/POST parameters tracing in access logs :

Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/openjdk-11
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

	Show the state of docker container :

Container testTomcat9 [19bd91f803a3] on image tomcat:9
on ports : 0.0.0.0:80->8080/tcp | size  32.8kB (virtual 705MB)
with size :  32.8kB (virtual 705MB)
	On Linux (not on Mac OSX) you can view Tomcat Catalina home folder in :

/var/lib/docker/volumes/TOMCAT_FOLDER_ROOT/_data


	You may access to internal container system via the next command :
	docker exec -it testTomcat9  /bin/bash
¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤  END  ¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤

you can follow the log file directly from the host (on Linux not on Mac OSX) by typing : sudo tail -f /var/lib/docker/volumes/TOMCAT_FOLDER_ROOT/_data/logs/_accesslog_withGetPOSTQueryString.log
send a POST request to validate another time : curl 'http://localhost/arcgis/rest/services/SampleWorldCities/MapServer/0/query' -H 'User-Agent: cURL' -H 'Content-Type: application/x-www-form-urlencoded' -H 'Pragma: no-cache' -H 'Cache-Control: no-cache' --data 'where=CITY_NAME%3D%27Cuiaba%27&text=&objectIds=&time=&geometry=&geometryType=esriGeometryEnvelope&inSR=&spatialRel=esriSpatialRelIntersects&relationParam=&outFields=*&returnGeometry=true&returnTrueCurves=false&maxAllowableOffset=&geometryPrecision=&outSR=&having=&returnIdsOnly=false&returnCountOnly=false&orderByFields=&groupByFieldsForStatistics=&outStatistics=&returnZ=false&returnM=false&gdbVersion=&historicMoment=&returnjsoninctValues=false&resultOffset=&resultRecordCount=&queryByDistance=&returnExtentOnly=false&datumTransformation=&parameterValues=&rangeValues=&quantizationParameters=&featureEncoding=esriDefault&f=json' -s > /dev/null

"classic deployement" :

first we need to declare the servlet filter for our webapp (in this case Esri ArcGIS Server) : /usr/local/tomcat/conf/Catalina/localhost/arcgis.xml

the content of the file is :

<?xml version="1.0" encoding="UTF-8"?>

<!-- The contents of this file will be loaded for arcgis webadaptor -->
<Context>
<Resources className="org.apache.catalina.webresources.StandardRoot">    
        <PreResources className="org.apache.catalina.webresources.DirResourceSet"
            base="/usr/local/tomcat/filter/lib"
            webAppMount="/WEB-INF/lib" />

<PreResources className="org.apache.catalina.webresources.DirResourceSet"
            base="/usr/local/tomcat/filter/conf_arcgis"
            webAppMount="/WEB-INF/classes" />
    </Resources>
</Context>

note that you must update the Tomcat launch script : /usr/local/tomcat/bin/catalina.sh update near the line 251 you can set the HOSTNAME variable AND the DEBUG parameters (port 8081) for Eclipse debugging :

# -----------------------------------------------------------------------------------------------
# hostname variable used by access logging with filter to get POST & GET parameters /accessLogGetPOSTQueryString
JAVA_OPTS="$JAVA_OPTS -Dhostname=CuTe"
# DEBUG dans eclipse
JAVA_OPTS="$JAVA_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8081"
# -----------------------------------------------------------------------------------------------

update the file /usr/local/tomcat/server.xmladd at the end just after <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log" suffix=".txt" pattern="%h %l %u %t "%r" %s %b" /> --> :

<!-- Logs customized by oDevArc ! https://tomcat.apache.org/tomcat-9.0-doc/config/valve.html#Access_Logging -->

<!--     %a - Remote IP address
%A - Local IP address
%b - Bytes sent, excluding HTTP headers, or '-' if zero
%B - Bytes sent, excluding HTTP headers
%h - Remote host name (or IP address if enableLookups for the connector is false)
%H - Request protocol
%l - Remote logical username from identd (always returns '-')
%m - Request method (GET, POST, etc.)
%p - Local port on which this request was received. See also %{xxx}p below.
%q - Query string (prepended with a '?' if it exists)
%r - First line of the request (method and request URI)
%s - HTTP status code of the response
%S - User session ID
%t - Date and time, in Common Log Format
%u - Remote user that was authenticated (if any), else '-'
%U - Requested URL path
%v - Local server name
%D - Time taken to process the request, in millis
%T - Time taken to process the request, in seconds
%F - Time taken to commit the response, in millis
%I - Current request thread name (can compare later with stacktraces)
%X - Connection status when response is completed:
X = Connection aborted before the response completed.
+ = Connection may be kept alive after the response is sent.
- = Connection will be closed after the response is sent.

There is also support to write information incoming or outgoing headers, cookies, session or request attributes and special timestamp formats. It is modeled after the Apache HTTP Server log configuration syntax. Each of them can be used multiple times with different xxx keys:
%{xxx}i write value of incoming header with name xxx
%{xxx}o write value of outgoing header with name xxx
%{xxx}c write value of cookie with name xxx
%{xxx}r write value of ServletRequest attribute with name xxx
%{xxx}s write value of HttpSession attribute with name xxx
%{xxx}p write local (server) port (xxx==local) or remote (client) port (xxx=remote)
%{xxx}t write timestamp at the end of the request formatted using the enhanced SimpleDateFormat pattern xxx

put all the jar files into the folder /usr/local/tomcat/filter/lib including the servlet filter accessLogGetPOSTQueryString.jar
define the logger defining file /usr/local/tomcat/filter/conf_arcgis/log4j2.xml designed for getting servlet message themself (not the POST/GET parameters tracing) ; content is like this :

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="INFO">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">

            <AppenderRef ref="filter"/>
        </Root>
    </Loggers>
</Configuration>

After all these actions you must restart your Tomcat by calling systemctl restart tomcat.service and some requests send by curl like these :

GET :

curl 'http://localhost/arcgis/rest/services/SampleWorldCities/MapServer/0/query?where=CITY_NAME%3D%27Cuiaba%27&text=&objectIds=&time=&geometry=&geometryType=esriGeometryEnvelope&inSR=&spatialRel=esriSpatialRelIntersects&relationParam=&outFields=*&returnGeometry=true&returnTrueCurves=false&maxAllowableOffset=&geometryPrecision=&outSR=&having=&returnIdsOnly=false&returnCountOnly=false&orderByFields=&groupByFieldsForStatistics=&outStatistics=&returnZ=false&returnM=false&gdbVersion=&historicMoment=&returnDistinctValues=false&resultOffset=&resultRecordCount=&queryByDistance=&returnExtentOnly=false&datumTransformation=&parameterValues=&rangeValues=&quantizationParameters=&featureEncoding=esriDefault&f=json' -H 'User-Agent: cURL' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8' -H 'Accept-Language: en-US,en;q=0.8,fr;q=0.5,fr-FR;q=0.3' -H 'Connection: keep-alive' -H 'Pragma: no-cache' -H 'Cache-Control: no-cache'  -s > /dev/null

POST :

curl 'http://localhost/arcgis/rest/services/SampleWorldCities/MapServer/0/query' -H 'User-Agent: cURL' -H 'Content-Type: application/x-www-form-urlencoded' -H 'Pragma: no-cache' -H 'Cache-Control: no-cache' --data 'where=CITY_NAME%3D%27Cuiaba%27&text=&objectIds=&time=&geometry=&geometryType=esriGeometryEnvelope&inSR=&spatialRel=esriSpatialRelIntersects&relationParam=&outFields=*&returnGeometry=true&returnTrueCurves=false&maxAllowableOffset=&geometryPrecision=&outSR=&having=&returnIdsOnly=false&returnCountOnly=false&orderByFields=&groupByFieldsForStatistics=&outStatistics=&returnZ=false&returnM=false&gdbVersion=&historicMoment=&returnjsoninctValues=false&resultOffset=&resultRecordCount=&queryByDistance=&returnExtentOnly=false&datumTransformation=&parameterValues=&rangeValues=&quantizationParameters=&featureEncoding=esriDefault&f=json' -s > /dev/null

will produce in /usr/local/tomcat/logs/CuTe_accesslog.log file this type of lines :

GET::500::2020-06-05 18:30:10::?where=CITY_NAME%3D%27Cuiaba%27&text=&objectIds=&time=&geometry=&geometryType=esriGeometryEnvelope&inSR=&spatialRel=esriSpatialRelIntersects&relationParam=&outFields=*&returnGeometry=true&returnTrueCurves=false&maxAllowableOffset=&geometryPrecision=&outSR=&having=&returnIdsOnly=false&returnCountOnly=false&orderByFields=&groupByFieldsForStatistics=&outStatistics=&returnZ=false&returnM=false&gdbVersion=&historicMoment=&returnDistinctValues=false&resultOffset=&resultRecordCount=&queryByDistance=&returnExtentOnly=false&datumTransformation=&parameterValues=&rangeValues=&quantizationParameters=&featureEncoding=esriDefault&f=json
