Wait State Filtering
Database wait states are pauses or delays in database activity. While Database Visibility collects data on all wait states, you may be more interested in some wait states than others. You can specify which wait states that you want to exclude from being reported by the agent so that you can focus on the critical wait states.
To specify wait states to exclude, navigate to Configuration > Wait State Filtering. Check the boxes of the wait states that you want to exclude. The wait states you exclude are no longer displayed in the Top 10 Query Wait States metric. In addition, any future queries that experience the wait states you exclude are not reported by the agent.
