munin 2.0-alpha2, r3856:4124, 2011-1-19
Commits by bldewolf, feiner.tom, janl, knan, ligne, mha, ssm, steve.schnepp, lupe, jorne
Summary :
* Huge performance boost
* munin-graph is over, cgi graphing only from now on
* Enabling CGI HTML with an reworked UI
* use a binary DB to store spoolfetch timestamps (fixes growing file bug in 2.0a1)
* documentation cleanup
Enhancements :
* Better node side timeout error message allowing things to be found out if needed
* Properly label the bgbouncer queries-per-second graph.
* Properly return undef when the SNMP client returns noSuchObject instead of setting an error.
* munin-node: Insert a reset_timeout() call to enable the master to get in a word in edgeways after a slow plugin has executed
* munin-html: Start using fork to save some wall-clock time. Option --fork us now active and max_html_jobs is recognized by munin-html as the maximum number of paralell processes.
* Actually recognize max_html_jobs as a config parameter
* Add the publication part
* Clean up Perl warnings due to use of undefined variables in two functions in LimitsOld.pm.
* looking at the Net::SNMP doco, -username cannot be '' (it must be between 1 and 32 characters).
* The time of munin-graph is over, cgi from now on
* since pollers are now being respawned if they fall over, the shutdown-spooler signal handlers need to be removed before starting any poller up.
* Cleanup of munin-cgi-graph:
- Make it log right
- Make it fast (now <0.1s pr graph on reasonable hardware)
- Remove $config deep copy, it is too expensive, we need to fix
expand_specials instead.
- BUG: Broke --pinpoint processing
* Munin::Master::Utils:
- Replace some often used REs with string matches for speed. Helped
speed up munin-cgi-graph quite a bit. Introduced munin_dumpconfig
to help debug the expand_specials issue
- Introduce munin_find_node_by_fqn to do faster lookups of things
to graph.
* Munin::Master::GraphOld:
- Restructure a bit to avoid double loading of $config (in
cooperation with munin-cgi-graph) and make it possible to pass
some graphing options (--only-fqn for example) in some new places.
- Propper logging the right way
- NOTE: All code relating to host and service filtering and looping
should be removed soonish - we're only using the FQN to find our
work now.
* Replacing 'echo -n', which is implementation-defined - with printf, which is posix
* munin-update: Add local URI scheme to enable running async collector directly on the master as this may somehow enable push-to master. Closes #981, thanks to jorne
* ALWAYS dumps the RRD cmd used when an error occurs when RRD::graphing
* Add some extra HTTP Response Headers
* JMX refactoring by Joachim Sauer
* add some external tools to ease a Storable datafile
* Enabled multigraph capabilities for the munin-async-server
* Re-work filtering in linux df plugin to be much more flexible.
* Force lpstat to C locale instead of EN_us.

exporting an undefined variable to the environment. thanks to Aleksandar
Lazic (al4711) for the patch. (closes #896)
* fix bug where snmp__netstat plugin can massively undercount the number of
connections.

tidy and more efficient. Thanks to Michael Renner for the
deveopment of this and porting to multigraph
* linux/cpuspeed: Specify "average" for the speed, switch to printf to
get numbers printed in full, E notation looses significant digits
and there are whispers of a bug in the E notation handling in
munin-update
* Make munin-update --nofork not die when nodes are unavailable. Closes #800.

- document need to run as a user with device access
- Support some debugging
- detect if smartctl fails
- detect if no recognized temperature output is present
* lpstat: Warn if the predefined $lpstat executable is not executable,
Make lpstat path configurable and search for it in likely places if
it's not set. Patch from Lupe - thanks! Closes #826.
* dhcpd3: Only emit .max if the .max is valid. Document a bug from
the trac - adresses but doe not close #829. Patches for a complete
fix welcome.

Makefile and munin-check
* Fix issue where far too many mails would be sent by munin-limits
(fixes #795)

munin-node-configure reject it.
* linux/yum: Enhance statefile error message. Update to use M::C::Defaults
* linux/vserver_*: Add autoconfiguration (patch from #811 submitted by
proppy, closes ticket).
* munin-update: Make true check into defined check to avoid dereferencing undefs
* Munin::Plugin:
- Better documentation of new default state file name.
- In need_multigraph, if run from a tty with "config" or no arguments
advice to use munin-run and exit.
* mailman: User contributed patch to make plugin work better the first
time. Also replaced "exit $n" with "die" with good error messages.
Untested but perl says syntax ok.
* hddtemp_smartctl: Added chomp, as it won't work with a newline at
the end. Thanks to Ingvar Hagelund for pointing this out
* munin-update: Suppress warning "Error reading includedir directory"
in case the includedir is empty (which is the case in new
installations. This caused cron to send these messages all the time
* Munin::Master::GraphOld: warn_min/warn_max typo fix
munin 1.4.2, r3167:3231, 2009-12-16
* Munin::Plugin::Pgslq: Clean the fieldnames before returning them, so
we don't generate invalid data with for example a dash in the
database name.
* jmx_: Add authentication support, fix exceptions in various memory
related parts, refactor connection negotiation to one central
connection class, add default connection info for jmx_, so we
actually are a bit autoconfy
* munin_update: Update to work correctly with 1.4, document and enhance a bit
* munin_stats: Provide better graph_info and set some warning and
critical levels at 4 minutes and 4m45s
* Improove colors contrast in jmx plugins which have Max area, to make
them more readable + fix some indentation

* Munin-(node|run): Make group name resolution lazy, enhance error
messages and reinstate the group foo,(bar) syntax
* munin-(node|run): Set umask to 0002 so that state files are group writable
INSTALLERS: chmod g+w on the files in your state directory
(/var/opt/munin/plugin-state in a default install)
* multips_memory: New plugin graphing the sum of the memory usage of
different processes matched by regular expression.
* Perl modules should not have x bit set: Remove on *Old.pm
* munin-update: Make I/O timeout fatal to terminate
munin-update<->munin-node communication otherwise the two parties
falls out of phase (or we need to introduce a RESET command or close
and reopen node connection, but I don't want to do that, esp. not
now). Handle the fallout of making it fatal.
* linux/load and linux/cpu: Correct warning/critical documentation
* postgres_querylength_: Fix query that can never have worked...
* Switch fonts to DejaVuSans og DejaVuSansMono. Vera is now obsoleted
by DejaVu in most contexts.
INSTALLERS: On platforms with RRD 1.3 the fonts need not be removed
and no paths need to be installed as long as the DejaVuSans font
family is installed.
* Reorder somewhat to get lines on top of areas
* Patch from blueyed to make munin-*cgi-graph work
* snmp__if_multi: Only set .max if the interface speed has been obtained

* dhcpd3: re-fix deprecated non-0 exit on autoconf
* add freeradius plugins from Alan DeKok and adapt better for munin-trunk
* linux/df_inode: Small pod correction and add debugfs to df_inode exclude list
* linux/df: Added debugfs to df.in exclude list
* Apache plugins: Exit with proper error of LWP::UserAgent not
found. This can happen if someone configured the plugin manually, or
if the plugin is installed when LWP::Useragent is installed and
passes autoconf, but sometime later LWP::Useragent is
removed. Without this patch the error message is confusing: Cant
locate object method "new" via package "LWP::UserAgent" This also
keeps autoconf output sane even if LWP::Useragent is not available
* linux/ip_: Actually support ipv6. Munin does actually handle : in
plugin names right
* make rpm does not work and won't work. Remove makefile target and
spec file. Might be added back later.
* There are no new autoconfiguring plugins in this release.
munin (1.4.1, r3116:3166, 2009-12-04)
* munin-node: Introduce a select loop to read from plugin
output/errors and avoid locking up
* munin-node: Plugins that time out must not be added to service list
* Looked into making sunos/memory use kstat but that's a hack of more
than 30 minutes, so document dependence on top instead
* hddtemp_smartctl: make it quiet on systems that lack smartctl
* sunos/iostat plugin now works
* linux/load: Correct documentation on how to set warning levels
* sunos/load: Set more graph_ things, including graph_scale no to
avoid "milliload"
* Update exim_mailqueue plugin to use exiqgrep instead of exim, closing #780
* sunos/df*: Add handling of /cdrom and /media mount points (ignore them)
* M::M::Utils: Remove the "*BUG*", it is wrong and worrisome
* linux/df*: Reinstate the warning and critical levels. Document how
to set them.
* munin-graph: Correct ordering problem in command-line.
AREA|LINE/STACK sequences must not be interrupted by HRULEs and
such (broke graphing of old cpu plugins)
* munin-graph: warning lines without range endpoint gets better detection.
* linux/df: Reinstate the default filesystem filling limits. Document how to
set them.
* linux/if:
* Munin::Plugin: Support default values for warning and critical levels.
* munin-*cgi-graph: Untaint the whole hostname, not only the first
occurance of something unholy
* Munin-*cgi-graph: Let "." be legal in hostnames.
* munin-graph: Recognize "max_graph_jobs" in the configuration instead
of logging errors
* Also add munin_cgi_graph_jobs to the legal keywords
* make tar now produces munin-$VERSION instead of using underline between
* linux/if_: This change prevents the linux if_ plugin, when run as
non-root, from leaking stderr output from ethtool to the log.
* postfix_mailstats: MUNIN_PLUGSTATE is an environment
variable. Thanks to pkhamre for reporting this.
* linux/fw_forwarded_local: check for readability with test rather than cat.
* Fixes to Announce-1.4.0
munin (1.4.0, r3033:3115, 2009-11-27)
* Give the docs a once-over and update ChangeLog
* Update plugins.history
* Mention Aleksey Studnev in jmx_ doc
* Merge patch from debian bug http://bugs.debian.org/507069 where
netstat plugin counts \"active connections rejected because of time
stamp\" as active connections, because of a lax regex
* amavis plugin: Minor pod fix
* Add snmp__print_(pages|supplies) printer plugins
* jmx_: nitpicks
* Fix #739: Perl error message only appears when there are no plugins
on any nodes, so check that and LOGCROAK in a helpful way
* munin-update: Change LOGCROAK to WARN for munin includedir missing
or empty
* Munin-node-configure --snmp: modify host enumeration code so
hostnames that are passed in aren't indiscriminately converted to
IPs. only works with plain hostnames, not CIDR.
* Remove Log::Log4perl TRACE level use since that requires a too new
Log::Log4perl
* Munin::Plugin::SNMP: Added support for env.timeout for SNMP sessions
* Add and extend the UPGRADING doc
* Remove reliance on the very newest Getopt::Long version, update docs
accordingly.
* linux/files_: fix slightly odd usage of awk. the warning and
critical thresholds are static, so they can just be echoed along
with the rest of the config.
* Postgres plugins: Correct pod from Munin::Plugins::Pgsql =>
Munin::Plugin::Pgsql (singular plugin, instead of plural)
* Munin::Plugin::Pgsql: Correct Pgsql.pm plugin configuration
documentation section
* Correct the generic crontab install command
* Typo fixes in docs
* Munin-node: Provide a different statefile for each master. Helps
prevent plugins that rely on their state-file from reporting
incorrect data when used on a plugin that is polled by multiple
masters. It uses the master's IP address, so it won't work if they
are both behind the same NAT gateway, for example.
set_state_name() in Munin::Plugin is also modified to behave in a
similar manner.
Additionally exports $MUNIN_STATEFILE into each plugin' environment,
so that all plugins can partake thereof. Should be useful to
plugins written in languages other than Perl.
* Update 1.4 documentation
* Munin::Plugin: fix $Munin::Plugin::DEBUG. it wasn't being set
(lexical variable $DEBUG was being set in its place). change from
"use vars" to "our" for all the externally-accessible variables, to
make it clearer what is going on. + fix indentation
* munin-limits: Check if $children is undef before using it as a array
reference. Fixes #762
* snmp__if_multi: Call "need_multigraph" function to avoid working
under the wrong circumstances
* dhcpd3 plugin: Critical and warning limits added. Some cleanup and
minor fixes.
* Munin::Plugin: straight port of the multigraph assertion sub from Plugin.sh.
* netbsd/sensors_: according to
<http://munin-monitoring.org/wiki/protocol-config>, graph_vtitle
has been superseded by graph_vlabel.
* a few more tests for Munin::Common::Config.
* linux/fw_(packets|conntrack): check for readability not existence
bail properly if /proc/net/snmp cannot be opened.
* Fix #758: Enhance and fix error propagation, fix exception handling,
fix sub-process waiting/reaping, and finaly print old config data
for failed nodes in a working way (probably worked before, but I
broke it when I retooled how old_service_configs is read)
* Munin::Master::ProcessManager: Correct the join command, which
resulted in not printing the firewalled host - now it does :)
* Returning iostst* to family auto, and moving diskstat_ to manual,
until we have multigraph support added to diskstat leaving diskstat
in auto without multigraph creates 3 graphs per disk, and on multi
disk machines this makes the main html quite heavy
* Uncomment includedir /etc/munin/munin-conf.d in munin.conf.in, and
make sure Makefile creates the directory at install time
* add some tests for Munin::Common::Config.
* Munin::Common::Config: populate the valid keyword hash directly,
rather than through an intermediate array.
* linux/diskstat_: Remove fake_munin_plugin, as we know we include
Munin::Plugin , no need to fake it :)
* munin-node.conf: only specify setsid once in the config file
* squid_traffic: hit_kbytes_out needs to be converted to bits, as with
the other data series. fixes Munin ticket #761 and Debian bug
557385 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=557385>.
thanks to Samuel Leon <leon36@gmail.com> for the patch.
* Prepare announcement of 1.4.0
munin (1.4.0-beta, r2982:3032, 2009-11-21)
* ejabberd_: Fix some documentation and other problems, move to
generic plugin directory (not Linux specific software)
* No .t files in the TAGS file!
* munin-update: Make rrd files even if the DS label evaluates to false
in perl (e.g., foo.label 0)
* bind9: Parse query logs with view information. Closes #661
* linux/ip_: Avoid matching x.x.x.2 with x.x.x.24. Fix is "obviously"
correct and has only been syntax checked
* linux/ip_: Document that we won't support rule matching on the "any"
firewall framework
* linux/cps_ (LVS) plugin fixed by incurporating patch in #636. Not
tested beyond a syntax/autoconf test
* bind9_rndc: Parse BIND 9.6 stats output.
* exim_mailqueue: Add documentation about user required to run plugin and
modidy AWK script as the default action is to print the whole line, which
was done...
* Various fixees to various plugins
* sunos/iostat: New plugin showhing I/O thruput on Solaris
* exim_mailstats: count the number of received, rejected and completed
emails using regexes rather than substr(). fix for ticket #698.
also suppress stderr when fetching the log_file_path, remove some
unnecessary code, improve error when the logfile is unreadable, and
tidy up here and there.
* dev_scripts/install: add install-plugins-prime to the targets run
during a standard install. makes working on plugins rather easier,
since a full, slow, salted-earth reinstall isn't required.
* postfix_mailstats: remove processing of rotated logfiles, as decided
in ticket #631. also includes a bit of tidying, and descriptive
error messages when bailing rather than relying exclusively on exit
status. i don't have a postfix server to hand, so this is not
exactly well tested...
* Plugin execution: remove undefined elements from the plugin command
passed to exec. this fixes the underlying problem the yum plugin
was encountering earlier.
* linux/yum: change yum plugin so it ignores defined-but-empty
arguments. makes fetch work again.
* munin-graph: Re-introduce line continuation in the rrdtool graph
command debug output
* Make munin_graph immune to redundance in graph_order field
* M::M::Config: Enhance a error message to include input line number
* linux/fw_conntrack: Let there be a total.value even if the input is empty
* linux/diskstat_: Document problem with multiple masters
* overview template: Remove COMPARE links as we will not be able to make them
correct in any reasonable timeframe. The datastructure we have now does
not support that O:-)
* munin.conf.pod: Removed the list of example required parameters
configurations from munin.conf man page, as they are not required
anymore, instead moved them to the explanation section for each
parameter, showing the default
* linux/iostat: Changed to manual, as they are replaced by the new
diskstat_ plugin by Michael Renner
* linux/threads: make a little less racy (and a tiny bit more
efficient to boot). it's still not perfect, because even now
there's a gap between the shell expanding the glob and grep getting
round to reading the files, but at least it complains less.
* log anything that plugins print to stderr. also sends a brief
message back to the server explaining what went wrong. fix for
ticket #582.
* munin-graph: Stop trying to copy cdef when aliasing fields in
graph_order -- 1.2 doesn't do that.
* Changing munin.conf.pod, munin-cron.pod to munin.conf.pod.in
munin-cron.pod.in. Adjusting Makefile accordingly. Closes #753
* munin-node: Do "next" on weird filenames not "return" so that we
read all plugin config files
* favicon for all templates. Refactored the finding of the root path
and css name in the process. Added tests for get_root_path
* modify how nested timeouts are handled, as discussed with janl.
this fixes the bug whereby a connection to munin-node would be
unexpectedly terminated if a plugin took more than 10 seconds to
run, regardless of whether this was allowed by the plugin
configuration.
* Catch problems if someone forgot a "address <IP>" or "update no" -
and make it plain in the error message.
* Use_node_name should default to "no". Closes #757
* Clearify munin_set_var_loc error message so we know what value is
set illegaly
* munin-node: Improve error reporting during startup by sort of
merging it with _run_service(). move the eval to the very top of
the event loop so as to avoid interfering with the session timeout.
* linux/fw_conntrack: Now works in 2.6, closes #532, thanks :-)
* Added ejabberd contrib plugin, moved from debian patches
munin (1.4.0-alpha2, r2899:2981, 2009-11-13)
* set obsoleted tomcat_* plugins to family=manual
* smart_ - fix autoconf yes and suggest empty
* openvpn and misc ntp_* plugins: fix some nonzero autoconfs
* mysql_: fix autoconf for missing Cache::Cache
* zimbra_: fix autoconf when missing perl modules
* Fix brokem munin-cgi-graph, which was : missing : --list-images param
for munin-graph, a missing chomp($file), and a wrong path to the
generated png. Also fix HTMLOld passing an array ref instead of an array
* a bit more debug output for the node server -- note which node each
plugin is associated with, and whether it requires multigraph.
* report when plugins are being ignored due to errors when they were
being configured. not very detailed, but better than nothing. also
delete them from the list of plugins, so they're not included in the list.
* Munin-node: fix logic in _suggested_links():
+ never return any suggested links when the plugin shouldn't be installed.
+ correctly handle SNMP plugins whose only wildcard parameter is the host.
(thanks to janl for spotting this was broken.)
* Add proof of concept snort plugins
* snmp__if_multi: Update to acutuall implementation of multigraph and some
further testing and corrections
* INSTALL: Update w.r.t. support for SNMP v3
* munin.conf: Correct "includedir" example
* postfix_mailqueue: Fix autoconf for the negative case, pretty sure it
still works for the positive case O:-)
* Fix various autoconf problems with slapd and ifx plugins
* mysql_* plugins: Now obsoleted by new mysql_ plugin. Set family=manual
* Asterisk_* plugins: None of these support autoconf so remove magicmarker
* HTML: Border on graphs in critical and warning state for nodeview.
Comparison views (hopefully) to follow
* M::M::Utils: End the pod section with =cut, so that the last line,
# vim: syntax=perl ts=8 wont slip into the man page
* M::M::ProcessManager: documentation typo fix
* bind9_rndc: reinstate @@PERL@@ substitution marker, which broke in r2958
* Get the BIND logfile's size before rndc is run, rather than taking a
guess at where it might have been. Fix for #746, thanks to guillomovitch
for the patch.
* Clean up a typo, add use strict, use warnings to all 3 apache_* plugins,
add an info explanation for apache_accesses
* HTML: munin-serviceview: add column header on 6th column in legend table
* M::M::HTMLOld: removes underscore from top navigation element describing
the plugin name for the service page emission. you know for the visual
touch
* HTML: added variable to set the text for the dropdown for each of the
template emitting functions.
* Refactoring templates into partials (with include) to avod a lot of
duplication. There is some left. Better look on the legend table for
service-biew and dropdown with 'other' links with config
value. Default is 1 at the moment. Makefile adds install steps for
new partial folder
* M::M::UpdateWorker: Typo--;
* linux/df_inode: vfat doesn't have any inodes either.
* More documentation of plugins
* Graphs: Fix cur: values for .stack and .sum.
* Graphs: ADDNAN in expand_specials cdefs
* Remove .label requirement on .stack fields.
* Changed munin_stats to check for
$Munin::Common::Defaults::MUNIN_LIBDIR/munin-update existance +
executable in order to autoconf it as previously it checked for the
existance of the munin master logs, which did not exist in a clean
installation. Also added a check + extinfo message in case any of the
log files are not readable
* Fix copying of subhashes (#%#parent was broken in old version). Fixed
various issues in a couple of programs.
* M::M::ProcessManager: clarify what the numbers at the end of the log
message mean.
* M::P::SNMP: for some reason, Net::SNMP doesn't consider 'No Such
Object' to be a real error. Handle better in get_single.
* linux/ip_: Use env.hostname to replace ip-number in graph_title.
* pm3users_ : we can do colour now
* ipmi_sensor_ - fix autoconf for missing ipmitool
* M::M::Config: Handle continued lines (ending in \)
* M::M::GraphOld: Comment out utime call that interferes with rrd's
--lazy option
* M::M::Node: A missing .label isn't as fatal as all that. Insert a
value and supply .extinfo to explain more
* Make the linux/diskstat_ plugin work better w/o root access,
document a bit better
* Remove obsolete nagios specific munin-limits commands from crontabs all over.
* M::M::Update: Load datafile relative to the configured dbdir, not
the default dbdir
* squeezebox_: Various enhancements
* M::M::Node: More specific location of the missing label from the config output
* M::M::LimitsOld: Forgot to actually make this into a exporter
module. Thanks to Kevin Fenzi for pointing this out
* mysql_ plugin: Update vlabels for concistency
* Give the BIND plugins a graph_category as pointed out in email by Rado Rovny
* Update mysql_ plugin from upstream
* Get rid of munindoc.in from the installation (closes #742)
* INSTALL: More modules, and a section on using CPAN-shell
* Implement dropdown boxes for peers when there are more than
"dropdownlimit" number of peers. Implemented for all views except
overview, which is a special kind of, ehm, view. Also removes
underscores from names for graph peers to clean them up a bit
munin (1.4.0-alpha, r1560:2898, 2009-11-06)
* squeezebox_: Changes to support several players
* smart_: Exit 0 on autoconf as the doctor ordered
* Make munin-graph recognize --help
* Quite a bit of work on error messages and log messages
* munin_stats plugin: Accept logdir setting from plugin-conf.d
* processes and linux/proc_pri plugins: Add vlabel
* Handle domain_order as group_order.
* Sort peers properly (fixes #577)
* Fix handling of group_order and node_order (partial fix for #579)
* Munin-update: soften up the protocol error handling a bit
* Make munin-html tolerate --nofork - even if it has no effect. Document.
* mysql_ plugin: Fix "suggest" bug
* Add multigraph_tester plugin to test (and show off) multigraph features
* Add extinfo_tester plugin for developer aid
* Make use_node_name work again (fixes #739)
* One single instance of "includedir" in munin.conf is now obeyed to
implement a "drop directory" for munin-master configuration.
Example in munin.conf
* Add python-plugin OO framework as python-plugin
* Make M::M::Logger a bit more subtle about warnings when the logs are not
open (so that they appear somewhere instead of nowhere)
* Update plugin configuration for varnish_
* Make notifications work again
* munin.conf: Set HTML and CGI dir consistently
* Added new mysql_ by Kjell-Magne Øierud plugin, document origin, and
sentence the others to exile (family=contrib)
* Fix "make/make install" problems, document the other
* Change <img> framing a bit to allow coloured frames (once the templates are updated)
* Add multigraph support to all programs in the munin-suite
* mysql_innodb plugin: The "new way" of detecting InnoDB free space was changed
in 5.1.24, add a case to compare correctly.
* linux/bonding_err_: it's a counter not a gauge
* Perltidy quite a bit
* Retire fieldname.warn and fieldname.crit. The documentation has been
saying .warning and .critical for a number of years. Mass fix plugins
accordingly.
* Service view: Add hopefuly helpful explanatory text about
warn/crit/unknown states in the graph-info field.
* Get the HTML templates and CSS validating.
* Updated templates and CSS with stylish new elements, fonts and such.
Thanks to Knut Haugen.
* Switch to Log4perl on the master side. Node still has to use
old logging to avoid node-installation-dependency-hell.
* Ever more corrections to INSTALL
* Basic modularisation of munin-limits
* Move favicon.ico to templates, some of us need the HTMLDIR to be fully
re-generatable from the templates directory (in order to be FHS complaint)
* Commented some templates to make them easier to read and understand
* munin.conf: include cgiurl_graph example
* memcached_: New wildcard plugin
* Refactoring of munin-update, munin-node and munin-node-configure
by Kjell-Mangne Øierud and Matthew Boyle. Actuall tests for testing
the programs were added too!
* templates:
* html templates: The timestamp can't really be ISO8601 with the support
of portable strftime % formats so remove the T, and cover the
eventuallity that strftime does not support %z
* Make templates @@ free - less processing - change Makefile and
M::M::HTMLOld accordingly
* Put INFO and DEBUG statements into the locking code to make it debugable
* Fix bashisms in nutups_.in : function is useless
* Introduced some actuall debugging output to munin-html
* Cleaned up logging in munin-html and M::M::Utils
* munin-master: make getopt::long dependency explicit at build-time
* linux/df*: Ubuntu Karmic uses "none" as device a lot, so handle that
* HACKING.pod: Revert "Note to do 'make build' before trying the install
script."
* testplugin: Testplugin for various failure modes - developer support
* Node.pm: Sanitise plugin names
* Node.pm: Fix the fieldname sanitiser a bit
* Node.pm: Better error message for empty plugin list (links to wiki)
* If ntp_offset can read no values from ntpq, replace values with 'U'
to avoid master confusion.
* New plugin for Squeezebox Duo: squeezebox_
* Add plugin for connected PostgreSQL users.
* Cosmetic changes in munin-cron script to make it more failure obvious
and and clearify the ordering
* Minimal modularization of munin-html, munin-graph and munin-limits - now
half suited to include in munin-fastcgi-graph if we want to
* Turns out that the // (and //=) operator is new to perl so remove all use
* Add plugin for PostgreSQL tuple access count
* Add plugin for Slony (PostgreSQL replication) node lag time
* Add plugins for PostgreSQL scans (squential vs index)
* Support connecting to non-default database in pg plugins
* Support multiple parameters to pg plugins, using colon to separate
them.
* Document max_graph_jobs and max_cgi_graph_jobs (see also the wiki).
* Made munin-graph paralell (defaulting to 6 forked processes).
Adapted from 1.2 patch by Kjetil Homme. Many many thanks!
* check whether javac works before using it, skip java plugins if not
* pgsql: Properly apply filters to config query as well for wildcard plugins,
so we don't generate lots of nan fields in the graphs.
* munin-html: Do not try to calculate png size, use geometry of the file
in the filesystem instead. This will cause a propagation delay -
image sizes _may_ be wrong, until munin-html runs again.
* munin-graph: set m/a time of png to last modification time of the
corresponding rrd file (since reverted)
* Adapt patch in #3 to current munin-cgi-graph for non-fastcgi. Closes #3.
Thanks to blueyed
* Adapt patch in #3 to current munin-cgi-graph to obtain munin-fastcgi-graph
* Install munin-fastcgi-graph
* munin-update and family: Do not accpet hostnames outside [^-A-Za-z0-9].
Issue helpful error message if someone bumps into this.
* Munin-node-configure: always do "exit 0" even when saying "no" because
it _is_ a normal exit and we do read the stdout.
Mass fix of plugins in trunk.
* linux/cpuspeed: Documentation fixes and slight error-message enhancements
* Changed the Max memory for the jmx_ plugins to default to a light color
(just like apache_processes free slots graph) as currently Max got a dark
blue color, making it hard to read graphs
* Compile the java files with -target 1.5 and -source 1.5 so they will work
correctly on sun-java-1.5 and on (without this, when compiled using
openjdk/sun-1.6-jdk, they refuse to run on 1.5 jre
* New vserver plugins adapted from Debian
* New asterisk plugins adapted from Debian
* ipmi_sensor_: Applied patch from http://bugs.debian.org/490093 so that
the graph scale always starts from zero
* Add ipmi_sensor_ wildcard plugin from Debian branch, and POD it
* Massive PODing of plugins for use with munindoc by Stig Sandbeck Mathisen
Many thanks!
* New plugin: openvpn.in from debian, and POD it gently
* Added the ability to customize the install location for the jmx java
library. As most distributions wont want it in the default munin libdir
* munin-node-configure needs pass the list of plugin names through to
apply_wildcards() too. part of #718. thanks to knan for the report.
* Munin-node: Clean up man-pages, and try and standardise common information
across all three applications.
* Report errors against plugins with inconsistent/unexpected magic markers.
* Java plugins written by FIX. Adapted for inclusion in munin by Erik
Bolsø, Tom Feiner and Ilya Kikoin. THANKS!
* Applied patch by Katriel Traum for snmp__memory that converts the plugin
