grafana timeseries data request errors

Hi all,


Just installed a default NetApp Harvest system.  All default.  All looks good except in various dashboards we are getting "Timeseries data request error".  Any recommendations of how to fix the issue?


Thank you

I see a lot of this:

Hi @rsr_72,


Maybe your filesystem filled up?

Yes, thank you.  I used something similar, the drive did fill up.  All looks pretty good, still get a few timeseriers error messages, but not many.
