I created a Windows service that connects to SCOM to collect unacknowledged alerts every 60 seconds. In the alert iteration process, the very first thing I do is post an update to the alert which indicates that the alert has been received. When I'm done processing the alert, I post another update showing that the alert has been processed. After processing the alert collection, I acknowledge them with the "AcknowledgeMonitoringAlerts" method.
The problem I am experiencing is that not all alerts are getting picked up by the connector, which is set up in OM with a subsciption to accept all alerts. This is happening randomly. One minute I'll see a specific alert for a specific server come through, and an hour later, the same alert for the same server will show up in Operations manager, but won't come through in the connector. This is evident in the fact that the history tab in the alert doesn't show the updates that should have been posted by the connector.
Anyone else seeing this type of behavior? Suggestions?
