This is joey! He hangs out every once and a while.
He loves long walks in the grass, long conversatons,
and sharing worms with his friends.
This plugin for Munin will show you the memory usage of your JVM that Tomcat is running in. This requires JDK 5+ and you must be starting your Tomcat with the jsvc command. This has been really useful in tuning the JVM memory settings for our Tomcat sites. You can click on the title to download the jstat__heap munin plugin. Place in in your /usr/share/munin/plugins directory then set a link in your /etc/munin/plugins/ directory with the name of jstat_www.domain.com_heap. You probably will have to also edit the /etc/munin/plugin-conf.d/munin-node file and add a jstat stanza for user root to execute the script.
