Hi Team,
Can some one tell why the below issues are coming in nagios. I just need comment as what are the reasons to generate the alerts. We are getting this alerts frequently then automatically states going ok after sometime. so if you can help what could be the situations to generate the alerts?
Service check timed out (What are the reasons to get the alerts)?
CHECK_NRPE: Receive header underflow. (What are the reasons to get the alerts)?
could not fetch information from server. (What are the reasons to get the alerts)?
Connection refused (What are the reasons to get the alerts)?
Connection reset by peer (What are the reasons to get the alerts)?
Command timed out (What are the reasons to get the alerts)?
Socket timeout (What are the reasons to get the alerts)?
Plugin timed out (What are the reasons to get the alerts)?
Invalid drive (What are the reasons to get the alerts)?
NRPE: Unable to read output (What are the reasons to get the alerts)?
terminate within the timeout (What are the reasons to get the alerts)?

Re: check nrpe/check nt communication issues
A lot of these are pretty generic errors, there could be a number of reasons behind them.
These are networking related errors.Connection refused (What are the reasons to get the alerts)?
Connection reset by peer (What are the reasons to get the alerts)?
Socket timeout (What are the reasons to get the alerts)?
These errors could come from one of a number of reasons where either Nagios or the server it is monitoring gets too busy to respond in a timely fashion.Service check timed out (What are the reasons to get the alerts)?
Plugin timed out (What are the reasons to get the alerts)?
terminate within the timeout (What are the reasons to get the alerts)?
These could also be tied to networking errors, like if the plugin receives only part of the response.CHECK_NRPE: Receive header underflow. (What are the reasons to get the alerts)?
NRPE: Unable to read output (What are the reasons to get the alerts)?

Re: check nrpe/check nt communication issues
If we get the unknown as check_nrpe response received as 0 bytes. For the remote script execution time what could be the reason
Re: check nrpe/check nt communication issues
Here's a good article that could explain that, and maybe some of the other messages.

Re: check nrpe/check nt communication issues
We are not getting regular basis we are getting in a day 2 to 3 times at the time for this issue what we have to observe in client side, Give the suggestion to us what we should check in client , we want to identify the issue.
I strongly believe that this is not related to command issue from server side which we are calling... Correct me if am wrong

Re: check nrpe/check nt communication issues
It's probably not command related if it's intermittent. Intermittent issues usually have something to do with network issues, and/or server load issues with either the Nagios server or the monitored server.

Re: check nrpe/check nt communication issues
Does nagios agent version will cause this unknown received 0 bytes. alerts??
Re: check nrpe/check nt communication issues
No, I would not suspect an agent version being the problem. If it was the problem, then I would suspect the it would be more consistent.

Re: check nrpe/check nt communication issues
So finally it's intermittent issue from remote server side right?
