your command definition in commands.cfg looks strange. You should use ‘–’ instead of ‘.’ as prefix to the options. I guess, this is a copy&paste issue.

Best result that I get is : UNKNOWN – An MBean name and a attribute/operation must be provided

/usr/local/nagios/etc/nrpe.cfg command[check_status]=/usr/local/nagios/libexec/check_jmx4perl –url http://:8080/jolokia –alias MEMORY_HEAP_USED –base MEMORY_HEAP_MAX –critical :80

/usr/local/nagios/etc/objects/commands.cfg command_line $USER1$/check_jmx4perl -u http://$HOSTADDRESS$:$ARG1$/jolokia .config $USER1$/jmx4perl/jmx4perl.cfg .check $ARG2$ .warning $ARG3$ .critical $ARG4$

/usr/local/nagios/etc/objects/server.cfg check_jmx4perl_config!8080!memory_heap!70!90

Anyone got any document to get this working with Glassfish? I mostly followed : http://www.op5.com/how-to/howto-monitor-application-server-op5-monitor-jmx4perl/

I’ve been told by some folks that there’s a PerfMBean to query but I’ve not had much luck with that. Anyone else doing WebSphere have a list of items they are monitoring?

Thanks! Dan

I just searching monitoring tool for java application — i hope it will works great–do any have the documentation for this how to configure this plugin in nagios!!!!

check_jmx4perl -u http://localhost:8080/jolokia -m java.lang:type=OperatingSystem -a ProcessCpuTime  --unit ns --delta 60 -w 1000000000

The check above gives you the time spent of your process within one minute (use –delta 1 for getting checking the nanoseconds spent in a real second)

Please note, that this value is not the CPU load, but the user+system time you Java process consumed. And it is measure in nanoseconds, although this doesn’t mean it has this accuracy.

And finally to answer your question ;-): No, it is not possible to combine –delta and –base (and it is not yet planned)

E.g. I would like to show CPU load in % within the last interval. I think I would need to put the delta for current and last values of “java.lang, type=OperatingSystem|ProcessCpuTime” in relation to the delta for current and last value of “java.lang, type=Runtime|Uptime”, but can I do a delta on the base value, too?
