Hello,

I have been tasked with getting some of our servers' time offset monitored. I downloaded the check_ntp_time plugin, set up the command, created a Service to use the command, and ran a check. It is returning an error saying that it is not getting a response from NTP servers. I have attached a screenshot.

How do I trouble shoot this error? I'm not sure what NTP server it is trying to reach.

Thank you!

In your example it would be trying to reach out to htcaweb01 on port 123 over udp to pull the time. The plugin pulls the time from the server specified with -H and then checks that time against the local machine's time.

AH! Ok, that makes sense.

Thank you! You may close this thread.
