A component-based blackout policy specifies a period of time during which incoming events that match the component selection criteria is ignored. All ignored events are logged.
Typically you define a blackout policy for a specific time frame or time frames, indicating when the policy is active, inactive, or both.
To create a new component-based blackout policy
Edit the component selection criteria by clicking Edit Component Selector to open the Edit Criteria dialog box.
You can devise component selector criteria by specifying the component class, a slot within the class, and a corresponding slot value. You can include multiple conditions by using the AND operator.
Some example component selectors are shown below:
BMC_BaseElement($CI) where [$CI.Name contains 'HR_Workways'] BMC_BaseElement($CI) where [$CI.Name contains 'HR_Workways' AND $CI.Department contains 'Warehousing'] BMC_BaseElement($CI) where [$CI.Name contains 'HR_Workways' AND $CI.Company contains 'ENEL']
To specify the periods of time when the policy should be inactive, select the Not Active Timeframescheck box and one or more timeframes from its scrollable list.
Note
You can select both check boxes to create active and inactive time periods. However, the inactive time period takes precedence over the active time period.
When specifying the time frames, you can indicate how you want to handle blackout events at the start, during, and at the end of the timeframe schedule. The actions under each timeframe period are mutually exclusive and are described in the following table.
During the processing phase, the blackout event policy evaluates each event for a match based on its selector only once, when it arrives at the cell. To maintain adequate system performance, the blackout policy does not evaluate events at the start and the end of every active time frame.
Actions for blackout events
Timeframe period | Action |
---|---|
At start of Blackout Window |
|
During Blackout Window |
|
At End of Blackout Window |
|
Note
Blackout event actions are applied to events based on their policy selectors when the events first arrive at the cell. If you modify an event after it has been processed by the cell so that it no longer matches its policy selector, the blackout event action is still applied to the event based on the initial evaluation.
administration console saves the defined event management policy, and it is displayed in the list of event policies for the selected event selector.
