   • Select the alarms you want to recover/delete, and click Recover/Delete to recover/delete them.
   • Select the check boxes next to the alarms you want to distribute, and click Distribute to distribute them to the specified processor of ITSM, which then creates an alarm handling process to follow up the processing of the alarms.
   • Select an item from the Refresh Interval drop-down list to set the interval at which the hierarchical alarm list is refreshed.
