Description:

The hpaagent and/or perfagent are failing without updating the hpaagent.log and prfagent.log respectively.

When you try to start them in debug mode, you will get the following result

C:\>hpaAgent start -l 5
FAIL hpaagent:hpaagent ( Fail to communicate with :
C:\Program Files\CA\SharedComponents\CCS\AT\AGENTS\BIN\hpaAgent.exe )
C:\>prfAgent start -l 5
FAIL prfagent:prfagent ( Fail to communicate with :
C:\Program Files\CA\SharedComponents\CCS\AT\AGENTS\BIN\prfAgent.exe )

Solution:

The performance agents will fail if the path is greater than 1024 characters.

To check if the path is greater than 1024 characters, type

echo %PATH%

Copy the result into an application like MS word, go to Tools and select Word Count (see Characters (with spaces))

If the path is greater than 1024, you will need to apply a MS hotfix ( see MS knowledge doc KB906469)
