Nagios XI unresponsive for tens of minutes after running the

Post by dlukinski »

Hello XI support

How we could optimize Nagios XI becoming unresponsive not only during the report generation, but for tens of minutes after the report was already generated: CMM and views remain painfully slow or unresponsive

Our Nagios VM (your built) runs with 8 vCPUs / 16 GB RAM at a moment

Thanks

When your system is in this state, do you have a "wkhtmltopdf" process running and taking a lot of CPU? It's possible that that could be hanging.
Also, have you done the various performance tuning tweaks that can help on large, busy systems, such as increasing various limits in the PHP config and the shared memory kernel paramters?

Have a look at:

...and let me know if that helps. If you want to PM us a profile, we can look at it, too.

Hi

PHP was already overclocked except for changing max_input _vars from 15000 to 50000 (just now)

I'll run some reports before trying other changes

Is this happening for a specific report or does it occur for all of them?

Does it stop other users or only your user?
