DPA query is consuming very high resources on a monitored server

Updated May 9, 2018


CPU usage on a monitored server is at 100% on a query called from DPA. 


  • DPA all versions 
  • Monitoring SQL Server prior to Cumulative update package 5 for SQL Server 2005 Service Pack 3 or a version prior to cumulative update package 7 for SQL Server 2008


The execution of a command in an alert SQL Server Error Log Alert that calls exec xp_readerrorlog stops responding and the usage of the CPU that is running the command increases to 100 percent. This is a known Microsoft issue.

Work around

In DPA, go to Alerts > Manage alerts. Then delete the SQL Server Error Log Alert, or deselect the instances from this alert that have the issue.
