I updated to v9.2.1.2308 and lost all historical data over 2 days. How do I see the data going back longer?

Hello,

this might be just a caching issue. Please try the following:

  • Stop both PRTG services (core and probe).
  • Head to your data folder (can be discerned from the Server Administrator tool, under the "Core Server" tab)
  • Delete the "PRTG Graph Data Cache.dat" file
  • Restart the PRTG services
  • Log in to the Web GUI
  • Go to "Setup ->PRTG Status-> System Status" and check the background tasks. It should state that it is calculating historic data

Then,

  • Refresh the page from time to time (is the number being reduced?)
  • Let it run until it is done and then take a look at the historic data of your sensors - it should now be available

This worked smashingly well. Thanks for the assistance.

Bout time to revive an old thread. I just upgraded to 19.1.48.2868 and lost my history. How do I get it back?
