Nagios Support Forum

Hello,

I'm new to using nagios. I'm using the default configurations for pinging our server. Is there a way to check if there are real issues happening from these notifications? Would there be a better RTA threshold to set it to?

Service: PING
State: WARNING

Additional Info:

PING WARNING - Packet loss = 0%, RTA = 112.19 ms

Since there's no packet loss I'm thinking there arent really issues? Thanks for your help and what advice you may have.

Did you install Nagios Core from source, or via a package manager? That may impact what your "default configurations" are.

If you installed from source, these are the default ping-related checks:

Maybe -- I don't know what is acceptable latency for this service, or your network in general If you're comfortable with 112ms for this particular check, I'd suggest adjusting the thresholds passed to the check_ping plugin.

By "default", the sample configs are returning WARNING at >=100ms (or 20% packet loss), and returning CRITICAL at >=500ms (or 60% packet loss):
