LoadRunner Controller Machine Throw "CPU usage exceeds 80%" Error During Test

We are using LoadRunner 12.  For several times we observed "CPU usage exceeds 80%" errors during tests.

The error still occurs after IT increased CPU 2.6 Ghz with 4 processors.  The OS is Windows 2008 Server R2 Standard.

I wonder anybody had the same problem before, and how it got resolved.

Thanks.

Re: LoadRunner Controller Machine Throw "CPU usage exceeds 80%" Error During Test

There might be various reasons:

  1. Your application uses huge foot print during the load test. You may need to reduce the VUsers.
  2. Monitor the CPU and Memory in the controller machine during the load test.
  3. You may need to clean up the temp and disk space in the controller machine.

Re: LoadRunner Controller Machine Throw "CPU usage exceeds 80%" Error During Test

I used to have the same issues but with the LG's.

What I did is distribute the load across all LG's, in your case, the controller, might be due too many users entering at the begining.

Anyways, this is just a warning alert, as long as you don't reach close to 100% like 96% and above you should be fine, just keep monitoring the test and if this became a problem (CPU maxing out) you will need to split your controller load to a second controller and split the licensing of virtual users between them.

Hope this helps
