Munin contributed plugins

#!/bin/sh

#

# Wildcard-plugin to monitor Java JMX (http://java.sun.com/jmx)attributes.

# To monitor a # specific set of JMX attributes,

# link <config_name> to this file. E.g.

#

#    ln -s /usr/share/plugins/jmx_ /etc/munin/plugins/jmx_java_threads

#

# ...will monitor Java thread count, assuming java_threads.conf file is located in

# /etc/munin/plugins folder.

#

# For Java process to be monitored, it must expose JMX remote interface.

# With Java 1.5 it can be done by adding parameters as:

#

# -Dcom.sun.management.jmxremote.port=<PORT> -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false

#

# For Tomcat to be monitored, add the following line in catalina.bat script:

# set JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote.port=<PORT> -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false

#

# By default, the plugin monitors localhost on <PORT> = 1616 using URL

# service:jmx:rmi:///jndi/rmi://localhost:1616/jmxrmi

# It can be changed by specifying parameters in  /etc/munin/plugin-conf.d/munin-node

#

# [jmx_*]

# env.jmxurl service:jmx:rmi:///jndi/rmi://localhost:1616/jmxrmi

#

# Read more on JMX configuring at http://java.sun.com/j2se/1.5.0/docs/guide/management/agent.html
