Usage
munin-java-plugins::default
Just include munin-java-plugins in your node's run_list:
{
"name":"my_node",
"run_list": [
"recipe[munin-java-plugins]"
]
}The munin java plugins leverage JMX to communicate to the JVM about the state of your application.
The recipe will automatically detect any running java processes in your ps tree and
find the JMX port it is using. It will specifically look for jmxremote.port=(\d+),
Example JVM argument: -Dcom.sun.management.jmxremote.port=7199
If it finds the port, which in this case is 7199, the recipe will create a plugin configuration file (generally located in /etc/munin/plugin-conf.d). Munin reads these files alphabetically and takes the last configuration block. Thus munin-node-jmx will be read after munin-node (package installed file), and if you need any further configuration, create a file in this directory to be read after munin-node-jmx.
If no port is found, the munin java plugins will be installed but not setup to run (i.e. no symlink from /etc/munin/plugins to the plugin)
Note: This recipe is written for only 1 JMX per host. Further improvement is needed to support more than one per host.
