i am using check_jvm plugin to monitor java threads,class count,heap memory and non heam memory
i am giving the command like this
command[check_jvm]=/usr/local/nagios/libexec/check_jvm -n org.apache.catalina.startup.Bootstrap -p heap -w 1073741824 -c 2147483648
but getting error like
UNKNOWN JVM is running with different username, run this script with UID 0
but i gave permissions to the script as root .as remaining plugins also same.
and i installed JvmInspector.jar also .

nagios4 check_jvm plugin
Re: nagios4 check_jvm plugin
If your Java process is running as root (UID 0), you'll need to also run your check_jvm plugin as root. This is a limitation of the JvmInspector jar file included with this plugin.
You should be able to do this with NRPE with sudo, assuming the NRPE daemorn or xinetd user is in sudoers.
JvmInspector doesn't need local or remote JMX network socket.
It directly attaches to JVM's PerfData, so it must be started with
the same USERid as the target JVM.
You should be able to do this with NRPE with sudo, assuming the NRPE daemorn or xinetd user is in sudoers.
Code: Select all
sudo /usr/local/nagios/libexec/check_jvm -n org.apache.catalina.startup.Bootstrap -p heap -w 1073741824 -c 2147483648
