To add to this .. the nrpe daemon needs to be compiled with <div><br></div><div><meta http-equiv="content-type" content="text/html; charset=utf-8"><pre style="font-family: monospace; font-size: medium; "> 1. Run the configure script with the --enable-command-args

What if I wanted to do something besides a check ping, maybe a disk check that requires the plugin to be on the server? Can I string something to together? Can anyone provide me with an example of this?</div>
<div><br></div><div>So I assume to do that the NRPE daemon needs to be running on internal db server. Which is fine, but when nagios checks through the proxy.. How do I configure it to display it is a unique host instead of the NRPEPROXYHOST?</div>
