SEPM Web server logs?

Hey All,

I am trying to troubleshoot a problem with symantec webserver. We have monitoring tool that integrates w/ webserver. When I run the getSavInfo I get this error

System.NullReferenceException: Object reference not set to an instance of an object.
   at SavService.queryRegistry(String hostname)
   at SavService.getSavInfo(String hostname)

Trying to find out if the logs will help. Log location would be most useful if anyone knows it.
