Your packages are no up to date, please consider to switch to a supported distribution like ubuntu/debian/fedora/opensuse or consider a repository subscription for RH and its derivatives.
also reactbundle is deprecated.

Apart from that…
is the loading time also that high if you turn off the graphite module?

Thanks for the notice.

I tried disabling the graphite module, but random occurrences of lag are still happening.

the graphite module was just a guess, because it is easy to disable.

Is there any other device on your network that is using the same IP address? this can also cause delays.

Apart from that I noticed that you tried to rename an icinga instance in another post.

Can you consider a fresh install on a supported OS like debian or ubuntu?
This would also fix your “security” concerns in this post

Yes, graphite didn’t do the trick.

Checked with nmap and it’s only 1 device up.

Yes, somehow I managed to do it. But it was quite complicated also used some scripts generated by AI to rename all entries on director database level.

Yes, that would be no easy task and long project, there is alot of dependencies and modules integrated on current monitoring system. Also I set up already some sort of dev Icinga on debian, certain packages e.g. Can’t locate utils.pm in @INC (you may need to install the utils module) are missing.
