Nagios Support Forum

WOW! That was it. My sudo settings by default said:

Defaults requiretty

So I commented it out, and now it freakin works. Hallelujah!

Thank you so much for your help!

Well it turns out that the hard disk on my Hypervisor is going bad. The Hypervisor would randomly just eat up disk I/O and cause only the NRPE checks to error out, even though on the VM server itself, there was no load. Weird.

Anyhow. Thanks for all the help!

It'll say:

CHECK_NRPE: Socket timeout after 10 seconds.

What's funny is that the server isn't being taxed, and it never looses ping.

Hey Everyone, I'm experiencing some weirdness on a particular host. About 3-4 times a day all NRPE checks on a particular host all of a sudden go critical. I've gone in and restarted the NRPE daemon, but that doesn't seem to fix it.I don't see any weirdness regarding NRPE in /var/log/messages. Any t...

when I try putting "sudo" in front of the command in the nrpe.cfg file, NRPE replies back on Nagios with an "Unable to Read Output". I have also ensured that the execute bit on the MegaCli64 file is set. [root@nas1 bin]# ls -al|grep MegaCli -rwxr-xr-x 1 root root 2236264 Jun 11 2...

I modified my script to utilize the full path for sudo: /usr/bin/sudo. Still doesn't work. NRPE runs on all of our server as a Daemon, not through Xinetd. Below is the nagios line in the /etc/sudoers files: [root@nas1 nagios]# cat /etc/sudoers|grep nagios nagios ALL=(ALL) NOPASSWD: ALL

Ah thank you! So entering a little bit of code to output the results helped. I changed the script output both the wc -l and the full MegaCLI64 command output to /tmp/test. #!/bin/sh # script to check the status of the RAID volume on a server with a Megaraid RAID card # Get status of RAID card COUNT=...

WOW! I must need some sleep or something.

So it turned out that on my service check I still had it doing a NRPE check.

Thank you everyone SO MUCH for your help. This falls under System Administrator error. DOH!
