How to Remove "(PerfMon Agent) Failed to Deserialize GetAgentIDResponse" Messages

The easiest way to get rid of such error messages is by updating your psappsrv.cfg file.

Filename = psappsrv.cfg, which shows the following:

[PSTOOLS]
;Set the value to 1 to Enable PPM Agents,0 to disable PPM Agents
EnablePPM Agent=1

If you saw the PerfMon error messages in the appserver logs, it means that your PPM agents are enabled i.e. EnablePPM Agent is set to 1.

To disable performance monitor agents on the domain, disable the PPM Agent parameter by setting it to 0 i.e.

[PSTOOLS]
;Set the value to 1 to Enable PPM Agents,0 to disable PPM Agents
EnablePPM Agent=0

Make the change in all the domains you need to and reboot those domains to remove the "(PerfMon Agent) Failed to deserialize GetAgentIDResponse" messages!
