# 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
|
||
