Has anyone noticed a high load average after upgrading to Nagios XI 5.3.3? I upgraded two Nagios XI instances on November 25th, and since then the load average on both has gone way up. I updated the OS around the same time, but I've already rebooted back to the previous Linux kernel with no effect.
Is it safe to try installing 5.3.2 over 5.3.3? I have a pre-5.3.3 snapshot I can revert to, but I'd rather not lose the graph data.
The Nagios hosts have 8 CPUs with 32GB of RAM, running CentOS 7. One has 700+ hosts and almost 16K services, and the other has 600+ hosts and 13.5K services.
High load average with 5.3.3?

Re: High load average with 5.3.3?
To the best of my knowledge, we have not had any reports of this behavior. Around the time of the spike, what is being recorded in the event log?
Home > Monitoring Process > Event Log
During the high load /cpu can you post the output of:
From a tech support perspective, it is not recommend to install an older version over new version, but I'm sure there's admins out there who have, perhaps they can chime in with some advice about it.

Re: High load average with 5.3.3?
I see a lot of runtime warnings and errors in the event log:
This is what top looks like during high load. Almost all of our checks are SNMP-based, so I'd expect to see that in there a lot.
And here is the ps output:
I cloned a new VM from a snapshot I took of the Nagios host before I upgraded Nagios XI and updated the OS. Its load average is around 3 so far, but it hasn't been running for very long yet.
These are the packages that would be updated if I let yum run. There are a couple PHP updates, so it's possible one of them is part of the problem:

These are the packages that would be updated if I let yum run. There are a couple PHP updates, so it's possible one of them is part of the problem:

Re: High load average with 5.3.3?
I've PMed the profile, thanks. For comparison, I've also attached current load average graphs from the Nagios host and the clone I made of its snapshot from before I installed 5.3.3. Almost 10x! 
I figure I'll install the OS update packages one at a time and see if any of them cause the load average to go haywire.

Re: High load average with 5.3.3?
Did you have base commands or wizard generated commands in the pre-5.3.3 XI installs? Your info shows a lot of failures. Failures from checks are expensive in much the same way an exception is expensive in programming. Such failures often occur after an upgrade where the user has customized commands or wizards as the upgrade would revert those items to baseline. There is a warning about this prior to the upgrade being run.

Re: High load average with 5.3.3?
I don't think I understand your question correctly. Some of the service checks were initially created by running the autodiscover wizard, but I reconfigured them to be assigned by hostgroup membership instead. As I've added more service checks, I've either written them from scratch starting by adding a new command (check_snmp_uptime for example) or I've copied an existing service check (which may have used a check_xi command) and modified the copy. I did add a "--timeout=60" parameter to the existing check_xi_service_snmp_linux_process command, but that persisted through the 5.3.3 upgrade.
Can you point me at the failures you found? All the service and command objects should be the same between my 5.3.3 host and its clone still running 5.3.2, with the only other difference between the two being the OS updates listed above.

Re: High load average with 5.3.3? [SOLVED]
The culprit turned out to be php-mcrypt 5.4.16-7.el7 from CentOS 7's epel repository. After I ran 'yum downgrade php-mcrypt' and reverted to 5.4.16-4.el7 from the nagiosxi-deps repository, the CPU load average went back to normal.
After that, I also reverted php-mssql just to be on the safe side and keep its version numbers the same as php-mcrypt's.

It looks like you marked your last post as [SOLVED]. Is it okay if we lock this thread? Thanks for choosing the Nagios forums!
