After move my node on different VM my Prometheus dashboard stat are empty

Hello,

I have move my node on different VM, I have reconnect my ISCSI target and all was working fine except for my dashboard that doesn’t show any stat like in the pic:

If I expand the timeframe of the stats I see all my old stat until the VM migration


what I have to do to fix it ?

Had a similar issue a few weeks ago…

Did you have rsynced your Node into a other Destination on iSCSI?
In my case i forgot to rsync with --delete option.

Take a look here:

the last rsync that I have complete before the switch was with --delete; this is the content of my directory:
