How can we stop PRTG from forgetting deleted sensor upon reboot?

Good Morning,

Every now and then we need to restart our PRTG server when it goes offline for whatever reason. We have noticed that after a reload, previously deleted sensors / name changes etc get reverted back.

For example, we could delete a sensor, the server could crash, when we reboot, the sensor is back there as if it was never deleted. Is this a known issue or something one our side?

Thanks!

Hello,

PRTG tries to "collect" configuration changes for about 5 minutes until they are written to hard-disk into the configuration file. This is done to have one larger write-access to the hard-disk instead of several smaller ones. And if PRTG now crashes before it can save the changes into the configuration file, you can't see them when PRTG starts the next time. So it's very important to properly shut down PRTG's services (this will also save all changes since the last save to the configuration file of course).

best regards.

Hi

Thanks for the reply. This does not seem to be working, however. Today PRTG went down but devices and sensors we had removed a good hour or so before were back on after the reboot, as if it is forgetting the changes recently made. Any ideas?

This is running a VM Box.

It would be good if you could send us your system log files for analysis. You will find the log files within the data directory as defined under the "Core Server" tab of the "PRTG Server Administrator" tool, or in the following default paths:

XP/2003: C:\Documents and Settings\All Users\Application Data\Paessler\PRTG Network Monitor\V7\Logs (System)
Vista/2008/Windows 7: C:\ProgramData\Paessler\PRTG Network Monitor\V7\Logs (System)

Please be aware that it might also be a 'V8'-folder. You can also use the option to upload the logs to our FTP-Server, using the button "Send Logs to Paessler..." on the tab "Logs" in the "PRTG Server Admin Tool".

Hello,

please don't get me wrong, but please do not upload the logs and make them publicly accessible, as for instance the Core Log contains your license key. I understand this is also my fault, I should have mentioned to send us the logs via email to [email protected] Anyway, seeing as you are running version 7.2.1 we would strongly recommend to update to the latest version of PRTG.

best regards.
