Hi, Yes of course it is : [root@myserver libexec]# ./check_nrpe -H localhost NRPE v2.12 I have a lot of other plugins running ok on this server (check_users, check_procs ...). Thanks for your help.

If I try this from the nagios server: ./check_nrpe -H localhost NRPE v2.12 so no -c switch, just the host. That means that the nrpe daemon is listening and we may poll it. you also need to define the command check_jmx somwhere in your client nrpe.cfg configuration file. I do not know how you installed nrpe in the machine you want to check, so I cannot guess where the file is. In a debian server it is in /etc/nagios/nrpe.cfg provided you installed the nagios-nrpe-server package from the debian repositories. If you installed from source I have no idea where it is, but it should be obvious from the documentation. -- groeten, natxo ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
