Monitoring is critical to staying in business, but that has to be balanced against pounding the people responsible 24 hours a day with "Critical" alerts that in my experience are not critical. To be specific the "Average Lock Wait Time (ms)" is constantly alarming at a critical state and sending out alerts. It is sending so many that I have caught myself tempted to not even look at the alerts, this would be bad because if I got an alert saying a SQL Server was down and I did not look at it.... well you get the idea.
For now, I will remove this metric from the SQL Server template. If tech support can prove their case that this is a real metric (that my 15 years of SQL Server experience disagrees with) that should be included, I will need a better threshold setting other than what comes with the module we bought.
