Nagios Support Forum

Hi, I installed the Nagios XI Linux Agent (the latest one that supports Amazon Linux) on 2 Amazon Linux instances and am able to monitor those from Nagios XI. I then installed Nagios Log Server and started getting a syslog feed from these two servers. I am seeing the following messages which imply that nrpe is restarting continously on the monitored servers:

I have just obfuscated the IP addresses here. are these normal messages, or is something wrong?

Dave.

Normal if NRPE is running from xinetd. Is it?

Yes, the Nagios XI Linux Agent installs nrpe under xinetd. So I guess nothing to worry about then? Other an a LOT of messages on syslog.

If everything is functioning as it should, this kind of logging is normal as jdalrymple said. You could check out the following resources if you're interested in turning logging off, though you may lose valuable troubleshooting information:
