We recently upgraded our SQL Monitor to version 5.1 and it appears there has been a change in the Blocking process metric. Before the upgrade we received an alert about a process that was blocking and after the upgrade it appears we receive an alert for each of the processes being blocked. We have set the threshold for 90 seconds and if there are three processes that are 30 seconds that total the 90 seconds, we receive an alert. However we don’t want to receive an alert for the 30 second blocked processes. Is there a way we can understand this change or configure it so we don’t get alerts that are blocked for less than 90 seconds?
