I'm starting to experience DPA Database Instance Monitor Errors when the monitored SQL Server is under a high load and users are experiencing timeouts.
I'm getting the message:
Monitor for database [WG-SQL] failed in job [QuickPollJob] due to [The query has timed out.]. Will attempt to retry every  seconds...
Is this something to worry about ?
If you go to your logs: <install_dir>\iwc\tomcat\logs and open contime.csv in a spreadsheet, filter it by the instance/database ID you are seeing the error in
AND by quickpoll* jobs.
We will attempt to execute 600 QPs in a 10 minute period. I consider about 80 - 85% of successful executions statistically valid - so anything north of let's call it around 500. If your successful executions at times dips below 500, you may want to open a support case and dig a bit deeper. If it is a highly active instance or unresponsive for any reason, these can time out.
