Advisor's generate events when the threshold defined on the Advisor is breached. Investigate the issue that triggered the event; rectify the issue or problem (or choose to ignore it); then close the event when you are satisfied it does not have a significant impact on your servers.
Some of the advisors identify transient or temporary issues, such
as a replication slave being unavailable. For these advisors, you
can schedule events to automatically be closed when the event
moves from notification status back to the
When auto-close is enabled, the event remains open while the condition that triggered the event is still in effect. When the condition is no longer in effect, the event is automatically closed. You can also manually close such events before resolving the issue. Events can also be closed by event handlers. For more information on handling events, see Chapter 18, Event Handling.
Not all Advisors generate events which can be auto-closed. See Chapter 20, Expression-Based Advisor Reference and Chapter 21, GUI-Based Advisor Reference for more information on the Advisors which support auto-close.
Events which support auto-close are closed by the Default Auto-close Policy after the event which triggered them is no longer in effect. For more information on Default Auto-close Policy, see Default Auto-close Policy. It is possible to override the Default Auto-close Policy by setting Auto-Close Events to No in an Event Handler
To close an individual event, click the [X] icon in the Actions column. Document the resolution using the Notes text area and choose the button. During the closing operation, you can also reconfigure the rule scheduling that triggered this event by checking the checkbox titled "After closing, take me to the page for adjusting schedules of Advisor(s) that reported these events." This option will open the Advisors configuration page with the related Advisors selected.
For more information on configuring advisor scheduling and auto closing, see Table 19.3, “Advisor Edit Menu Controls”.
To close a number of alerts simultaneously, select the checkbox beside each event to close and click thebutton.
When closing individual or multiple events, a notification window
indicates what operations have been completed. The events remain
in the displayed event list, but the close
link is instead a link to the
You can update the active list by clicking
to re-filter the event display.
A historical list of all events, including closed events, is
available by setting the Current Severity to
Closed. The list shows all of the closed events
for a given time range and the servers selected in the server
tree. Historical data is limited by the
purge data settings.
If a custom advisor is deleted, or one of the default advisors is made redundant and removed as part of an upgrade, their events can be orphaned. The system automatically closes events which have no advisor linked to them. A note is added to the event stating why it was closed.
