We have an issue I'm trying to solve. Every 12 hours our ESX hosts spike in CPU for about 15 minutes (at Midnight and Noon). We've figured out that it's VMWare VMAN Configuration polling that's causing it. We determined this by shutting that off and it not reoccurring. As well as looking at the database job the setup makes sense in that it runs every 12 hours, etc.
My question is, why does this happen and how do we prevent it from affecting the environment like this because as you can imagine this causes issues and confusion in the environment when we see a spike like that for all our VM hosts. It's simply not healthy.
So, my questions are this - Is there anything we can do to prevent the CPU spikes such as:
1. Can this be scheduled to run every hour instead which maybe will result in it pulling a smaller amount of data or will it do the same large hit against the ESX hosts just more often?
2. Is there a way to schedule this to run at like 7am and 7pm instead of midnight and Noon?
3. What is this doing that causes such a large spike and can SolarWinds change the app to be less of a hit to the system?
4. Any other thoughts?
Thanks in advance.
