Version 6. Server crash PRTG working, but lost most of my history

I had a "server interruption", and did not have a backup. When the server was recovered (loose term), PRTG (6) works, but I have lost my 365 day history. I only have my 30 day. I do see the folders and files for the history dates in my PRTG folder.

I need to rebuild the server soon. But before I do that, I wanted to try and get my historical data back, and then either move the installation to another server, or wait until I rebuild this server, and then reinstall PRTG and restore my data. Is there a way to (should I) put PRTG 7 on the new server and restore my info from ver 6. Can this be done?

Any help with these two issues would be much appreciated.

Thanks...

Hello,

if the old data-files are still existing, you could try (in PRTG 6) to Recalculate the Data Cache (see PRTG 6 - System Settings).

If you want to upgrade to PRTG 7 right away (and the data files are still existing as well), you could simply try to use the Import tool of PRTG 7 to get all data into PRTG 7 (with the known limitations: How do I Import Data from PRTG Traffic Grapher 6 or IPCheck Server Monitor 5 in PRTG Network Monitor)

Best Regards.

Thank you for the reply. I just did the recalculate. I think my issue is with the actual data (corrupted data) in the database. If I look at some of the numbers they are astronomically high and don't correlate to any others. I am POSITIVE this is a result of the crash. Is there a way I can just deletes a few days of data (or delete the actual bad data) from the DB.

I think what is happening is that the numbers of the corrupt data are so high, that it throws the scale of the graphs off. So I see two REALLY big spikes, and the rest appears as a flat line. If I could get rid of the spikes, I think the graph would "come back to life" .

Thoughts? Comments?

Thanks again.

Hello,

you could either try using the Spike Filter (see Advanced Sensor Settings), or of course delete the data files for those specific days. When using the 2nd option, you will have to recalculate the graph data cache again.

Best Regards.

Thank you. I deleted a few of the "corrupted" days and it works fine. Thank you.
