When /bin/sh used, script reports:

check_jstat.sh: 28: /usr/local/lib/nagios/plugins/check_jstat.sh: Syntax error: "(" unexpected

It should be '/bin/bash' in shebang.

Thanks.

When calculating the heapmx I believe the calculation should be adding $ygcmx + $ogcmx. When running this we are getting a false positive error stating we are using 147% of heap.

It seems that performance data is not in the expected 'Nagios Plugins' format, which is:

'label'=value[UOM];[warn];[crit];[min];[max]

https://www.monitoring-plugins.org/doc/guidelines.html#AEN200
http://docs.icinga.org/latest/en/perfdata.html#formatperfdata

This makes it hard to graph performance data with 'standard' tools (like pnp4nagios).

I don't see a need for PID in performance data output, so I would suggest this format (split into lines here for better view):

heap=heap-size-used(Bytes)
heap_max=heap-max-size(Bytes)
heap_ratio=%ratio;warning-threshold-%ratio;critical-threshold-%ratio
perm=perm-size-used(Bytes)
perm_max=perm-max-size(Bytes)
perm_ratio=%ratio;warning-threshold-%ratio;critical-threshold-%ratio

In JDK 8, jstat display Metaspace's statistics, but not PermGen's.

Hi
i want to monitor just Java service ps -aux | grep java

when i tried to run this plugin i got this message plz help me out what is the complete command

plugins]# ./check_jstat.sh -s Java
/var/run/Java.pid not found

Locally on the host works ok. When running remotely via nrpe on the monitoring server, the nagiosa shows: CRITICAL: process pid [] seems not to be a JAVA application

cat /etc/nagios/nrpe.d/check_SupportedKafka_memory.cfg
command[check_supportedkafka]=/usr/bin/sudo /etc/nagios/check.d/check_jstat.sh -j SupportedKafka -w 85 -c 95

su - nagios -c "/usr/bin/sudo /etc/nagios/check.d/check_jstat.sh -j SupportedKafka -w 85 -c 95"
OK: jstat process SupportedKafka alive|pid=2979 heap=258802;2097152;12;85;95 perm=46930;1091584;4;85;95

i have in sudoers files
Defaults:nagios !requiretty
nagios ALL=(ALL) NOPASSWD: /etc/nagios/check.d/check_jstat.sh

a try
nagios ALL=(root) NOPASSWD: /etc/nagios/check.d/check_jstat.sh

and the same result :(

edit:
I did a simple test - a check calling jps only. Locally, with sudo, he gives everything. After nrpe remotely only PID jps.
Maybe something with java or a new ubuntu?

Testing out the plugin and nagios is not accepting the input. Constantly getting 'CRITICAL: Can't get GC statistics' though I've edited the sudoers file. Any suggestions?
