Strange issue inside graphana dashboard after upgrade(s)

Little bit of backstory:

  • I updaded a 4 node cluster from Ontap 8.3.2 to 9.1P12 (soon to be 9.3Px)
  • OCUM from 7.1 -> 7.2 -> 7.3 (with the new updated .ova and a support case Smiley Happy
  • Updated Harvest from 1.3 to 1.4
  • Updated NSDK from 5.6 to 5.7
  • Upgraded ADVA from 2.1.5 to 2.42 (big step?)

Up to before updating ADVA all seemed to work well, apart from some values that I had to cleanup manually in the whisper folder ( i guess a kernel panic, ontap upgrade, and headswap can somehow cause this along the way ...! )




But after updating I get this silly little error and my dashboards are now empty!



just wondering if someone could share his hindsight on this Smiley Happy


i’m now rolling back and trying to upgrade ADVA to 2.3 first, maybe?
