Nagios JBoss Plugin Rumi, June 25, 2012 Perl script to check thread and memory usage of a Jboss server. I didn't like the Jboss checks that I've found which require Java or remote-run, so I wrote this. It's a simple check that looks at memory usage and busy threads. I did this with percentage thresholds to make it dynamic. Usage: check_jboss_status.pl [-H ] [-P ] [-t ] [-m ] [-a ] [-h ] -H The host to connect to (default: localhost) -P The port to connect to (default: 8080) -a The AJP ports to check for (default: 8009) -h The HTTP ports to check for (default: 8080,8443) -t The percentage of threads busy for warning (default: 80,50) -m The percentage of memory used for warning (default: 80,50) Example: check_jboss_status.pl -H jboss.example.com -P 8080 -t 90,75 -m 75,50 -a 8009 -h 8080,8443 This will check the host "jboss.example.com" on port "8080" and issue a warning at 75% thread busy or a critical alert at 90% thread usage, or a warning at 50% or critical at 75% JVM memory usage checking. for AJP port 8009 and HTTP ports 8080 and 8443.
