It seems to be fine so far. The status.dat and retention.dat files seem to be holding in the 800-900K realm, I will continue to see if it increases significantly. I am still running the maint version, just not as a deamon. Yes, once I renamed the super large status and retention.dat files, it became...

Further looking into this, I decided to roll back the changes and move it out of Daemon mode for a second and then I renamed the retention.dat and status.dat files to .old and restarted the nagios process. Those files had gotten to be 2.6GB each. In doing so, the web site is now flying at lightening...

Also, I should add that it looks like Nagios is stuck in the past. Looking at the status, the last checks were from 4 days ago. Looking at the scheduling queue, it's from 4 days ago.

Well, yes, the nagios process doesn't appear at all in the top anymore. I suppose making it a deamon helped that. But every call to a cgi starts by taking 100% CPU. It still takes over 1 minute to load any page on the site. It's still unusable. We also stopped getting email notifications. I guess I ...

I couldn't upload a 4th file in the last post. Here is the video.

Thanks. That helped get Nagios running. I have attached screen shots of where we are now including performance stats. Response times are still pretty slow on the UI. I don't see nagios in the top results anymore. Looking at top, the CPU is mostly idle and swap memory isn't being used until you try t...

So I did that and now it doesn't start after reboot... sysadmin@monitoring:~$ sudo service nagios status [sudo] password for sysadmin: ● nagios.service - Nagios Loaded: loaded (/etc/systemd/system/nagios.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Fri 2018-07-2...

I'm not sure. I followed these instructions for setting up Nagios. https://www.digitalocean.com/community/tutorials/how-to-install-nagios-4-and-monitor-your-servers-on-ubuntu-16-04 I presume this is where that would be controlled: sudo systemctl enable /etc/systemd/system/nagios.service sudo systemc...
