In the Cloud Console, Incident ruleset / rule has been configured for sending email notifications to administrators when certain conditions occur. Sometimes the email notifications are sent but sometimes they are not.
- When the notification is not sent, accessing event details for which notification was expected from Monitoring -> Incident Manager page and clicking on the 'Updates' tab shows an entry such as:
The following notifications will be sent: 1 email(s) with 1 recipient(s)
but the next annotation for the actual Rule which is supposed to send the notification is never updated.
- The Setup -> Manage Cloud Control -> Health Overview page shows that the 'Notification Backlog' is increasing gradually.
- If the OMS is re-started, all the pending email notifications are received.
- The <gc_inst>/em/EMGC_OMS1/sysman/log/emoms_pbs.trc shows:
