Many thanks to you.<o:p></o:p> <o:p> </o:p> Now, I don’t want to appear lazy; I’ve done my best to get the nrpe piece configured properly. I should say that I’ve used the Dag Wieers rpms to install nagios, nagios-plugins-nrpe, and nagios-nrpe (I don’t know the difference between the last two). Once again, at least afaic, the documentation isn’t that good. So, I’m going to push my luck and ask:<o:p></o:p> <o:p> </o:p> Do I have to add anything nrpe-related to the client machines? What directives must I add to what files on the nagios server? I’d like to start out by monitoring Current Users, Total Processes, and Disk Free Space. All of these boxes are Linux.<o:p></o:p> <o:p> </o:p> I’m real close here.<o:p></o:p> <o:p> </o:p> Dimitri<o:p></o:p> <o:p> </o:p> </div> </body> </html>
