When monitoring the Application event log, the EventSentry agent missed events between number 980 to 984. EventSentry will attempt to read those events at a later time to make sure that all events from the Application log are being processed.
Under very rare circumstances the EventSentry agent can miss reading a small amount of event log messages. The agent will try to read those events at a later time and is usually able to do so.
However, it is recommended that you review the event log to make sure that all events were captured by your filters.
The numbers indicated are the event numbers that you will only be able to see in the web reports or the built-in event viewer of the EventSentry management application.
