How do I reset the Max Service Check Latency?


I have made some changes to my Nagios configuration to improve its overall performance but I can not seem to reset the Max value for Service Check Latency on the Performance Info screen.

The Min and Avg values are updating but what I really want to see is the Max.

Restarting Nagios does not do anything.


I have the same issue. I need to reset the Check Latency stats.



well, I don’t know if there’s a better way to do that, but here’s how you can do it:
reload nagios with just one dummy hostgroup+host+service.
Then reload nagios with your normal config.

This will do a fresh start for all your services (you’ll see them as “pending” without any old status), thus erasing your performance stats.

note: as a consequence of that, you’ll lose some service history, status …etc. Don’t do it if you might need it
