Hello Nagios Support -

I recently upgraded an XI server from 5.6.14 to 5.7.3. I noticed rather quickly that the system is more susceptible to Host Check Latency and Service Check Latency. I've run into problems with Host/Service Latency in the distance past on long lost versions of XI - so I am monitoring and graphing this data on our XI servers to make sure the wheels stay greased.

I've attached a screenshot of the performance graph.
- Server was upgraded to 5.7.3 on September 21st, and 12:00.
- Server was rolled-back to 5.6.14 today at 12:00, using a backup.

You'll notice the large spikes up in Latency recorded, but there is even a baseline change where it seems a bit "noisier".
I understand NDOutils was updated in 5.7, and ndo2db was dropped. I worry that the performance issues are from this.

Is there any tuning I should consider, or is there any system info you would like know?

XI 5.7.3 on Centos 7.8.2003 - Latest updates and patches as of today.
955 Hosts - 6,378 Services.
Using large installation tweaks.

HI,

We have had some users impacted with check results not updating to the database as expected and are working to correct this right now. For the time being, I would recommend keeping this system on the previous version.

Is there any tuning I should consider, or is there any system info you would like know?

If you have a system profile before you rolled back, that would be helpful. The check latency issue could be caused by a number of factors such CPU spikes or database issues.

Thanks,
Benjamin

Thank you! I appreciate the advice.
