Monitor contention views

Monitor contention views

Monitor contention views show a table where every row corresponds to a waiting or blocking event on a monitor. There are two monitor contention views:
- current monitor usage view
  The current monitor usage view shows monitors that are currently involved in a waiting or blocking operation.
- monitor usage history view
  The monitor usage history view shows the sequence of waiting and blocking operations on monitors above the configured thresholds.
Note that these views are unavailable if monitor contention views are disabled.
