Check_udp for chronyd

[janellewhitting]

Hello,
I'm looking for an example of check_udp for a port. Any suggestion?

Hi @janellewhitting,

This forum post has a number of good examples for that plugin.

Let us know if this helps and if you have any additional questions.

Thank you!

The basic way to check if chronyd is running via UDP is to use check_udp -H <IP> -p 123. The Network Time Protocol (NTP) uses port 123, so this confirms the service is listening on that port.
