Collects the average wait time in milliseconds.
Average Wait Time (Milliseconds) for SQL DBEngine on Windows
The average amount of wait time (milliseconds) for each lock request that resulted in a wait. This counter based on the DB engine counter. This counter has identical values for all databases on the SQL instance.
This is the average wait time in milliseconds to acquire the lock. The lower the value, the better. If the value goes higher then 500, there may be blocking. You may find the cause of blocking and fix it.
Name | Description | Default Value |
Enabled | Enables or disables the workflow. | Yes |
Interval (seconds) | The recurring interval of time in seconds in which to run the workflow. | 900 |
Timeout (seconds) | Specifies the time the workflow is allowed to run before being closed and marked as failed. | 300 |
Timeout for query execution (seconds) | The workflow will fail and register an event, if the query execution takes longer than the specified period. | 60 |
Timeout for database connection (seconds) | The workflow will fail and register an event, if it cannot access the database during the specified period. | 15 |
