      As well as apparently multiple hundreds of …negatively…? executed CREATE, ALTER or DROP commands … averaging out to 0 per second.

      … resulting in a spike of negative, I dunno, 30mb/s of reads.

      Mhm yep.

      My initial guess is that failed/malformed attempts to … do something … are being registered as negative instead of being actually displayed as failed.

      But that seems to make too much sense.

      Second guess: Lightning strike.

      Third guess: Arcane, hitherto unseen bug or series of bugs utterly and totally unique to this exact set up which has somehow never occurred or been noticed before.

      Probably a traffic_bytes_counter got reset. You can see a lot of graphs went negative at the same time, so something probably restarted.

      Metrics software like Prometheus will handle counter resets correctly for graphs like this.
