MatchAll Alerts

Hi - Is anyone able to advise me what "MatchAll" events from Solarwinds actually mean.

SolarwindsID = 22512010 | OriginDateTime = 2023-05-31T08:47:34.1030000Z | Origin = AR-BUE-SNL-AVC | NodeID = 2864 | FreeText = MatchAll was triggered. |

I've got events like this one coming out of the system but not really clear what these are.  Do they mena the device issues are now resolved and its back up again ?
