High Cpu on Windows due to Solarwinds Job Enginer and Collector Services resulting into degraded performance

heldy over 1 year ago

Hi, We are seeing high CPU on Windows Servers mostly 100 percent whenever opening the SW web console, the website becomes completely unresponsive if trying to run jobs, and SolarWinds performance has been degraded significantly, we can't even get graphs info, and can't even change SNMP creds if we want to because our CPU remains spiked at 100 percent whenever we are doing anything for Solarwinds

The problem became visible after our NCM jobs were stuck on Post Processing.

Technical Support has not been of much help, they have tried figuring out the problem but could not find out why the job engine and collector services are spiking the CPU suddenly.

Solarwinds version 2023.1, our server is not under-provisioned from a deployment standpoint.

Whatever TAC did, it resulted in more degraded performance and other errors such as licensing errors even when are all our licenses are active. Troubleshooting has also made the website take much longer for displaying information than it was taking earlier.

Any help or suggestion is highly appreciated.

You might want to start to utilize Orion Insights. This would give you a background of the Environment where your SW is running. It can give you ideas how to optimize the software.

An update on this , after the engineer did some more troubleshooting last Thursday we were able to run the NCM jobs successfully and the CPU on the main Orion server seemed stabilized for now , but then after this we are see new kinds of error on Solarwinds Portal , such as warnings on License expiring soon ( although its good until October 2023 ) and some error such as below..any idea on this

For any concerns or issues with licensing, reach out to Customer Service or your Maintenance/Renewal rep, they're the only ones with the access to figure out what a licensing warning is about.

I added a screenshot of this post to the notes I sent on, per our direct message.

This error pertains to all your solarwinds servers not being on the same version.

Go to Resolution 3. That's a sure way to check for the versions between servers. Otherwise, follow cheryl1 advise.

Thanks, @donrobert5 Given some of the other issues, I'm very skeptical of this one, but I have asked a couple of support managers to have another look at this one.

heldy I chatted with one of the support managers I'd been working with this AM. He's going to have someone reach out to you and take another look. I apologize for the delay and the issues you're having. Hopefully, we can get this resolved.

Hi Thank you for your responses ...maybe I spoke too quick on the CPU part , today we are experiencing the same slowness and CPU staying high when accessing the Solarwinds console ..i tried checking Solarwinds version but it appears all polling engines are on version 2023.1 and since when i did upgrade on this Solarwinds instance , a TAC engineer was assisting me as was facing issues and after the upgrade they verified that the version is same on main engine and pollers
