Description

This command pauses or resumes the Event Log. When the Event Log is paused, it will not log any entries. When it is resumed, it will continue logging entries from the time it was resumed.

This command is useful for troubleshooting. A user program can wait for some event to occur and then pause the Event Log. Then later, the log can be uploaded via RMCTools and analyzed.

The number of entries the Event Log can hold is limited. If that limit is exceeded, the oldest entries disappear. Therefore, during normal execution of the Event Log, an error event may disappear before the log can be uploaded. Pausing the Event Log solves this dilemma.

This command is not the same as the Pause and Resume buttons in the Event Log Monitor toolbar. The Pause button in the Event Log Monitor stops uploading new Event Log items, although the Event Log is still logging. When the Event Log Monitor is paused, it will also try to backfill any missing items as much as possible. Because the Event Log is finite, the Event Log Monitor may not be able to backfill all its missing data.

When the Event Log is paused due to this command, the Error Icon and Error Bubble in RMCTools will not function.
