The script works fine when executed manually using the 'nagios' user which NRPE is running as: sh-2.05a$ /usr/local/nagios/libexec/check_apache OK - 68 requests being processed. However, via NRPE: /usr/local/nagios/libexec/check_nrpe -H localhost -c check_apache OK - requests being processed. Below is the script. I've tried many different code variations, but end result is the same. I appreciate any insight as to what the issue could be.

Although to me, it seems more like perl than NRPE. In a broader context the issue is about getting something different when running from the command line versus running through Nagios.<o:p></o:p> <o:p> </o:p> One that comes to mind that looks for processes consuming lots of CPU will tell me the specific process name when run from the command line, but tells me only "java" when run automatically via Nagios.<o:p></o:p> <o:p> </o:p> I have another script that runs great from the command-line, but blows up when it runs through Nagios.<o:p></o:p> <o:p> </o:p> I haven't had the time to dig in as much as I'd like and Nagios itself does not, unfortunately, provide much useful info from what I've seen to help you debug plugin problems. In this case though, I'm a little suspicious of ePN causing the different behavior as that's what's really different between my command-line runs and Nagios' automatic runs.<o:p></o:p> <o:p> </o:p> Mark<o:p></o:p> <o:p> </o:p> <o:p> </o:p> <o:p> </o:p> </div> </div> </body> </html>
