Monitoring changes to PRTG by users



In order to properly track changes to PRTG is there a way to get notified when a device or sensor is added or deleted? I know these things show up in the log.htm page but those logs are filled with other items. I need to specifically see when a device or sensor change was made and hopefully by which user.

If this isn't available in PRTG itself is there a log file I can manually search?

That would be the webserver access log, located under the following path:

C:\ProgramData\Paessler\PRTG Network Monitor\Logs\webserver\WebServer.log

Simply search for /deleteobject.htm. It will contain the following information:

#322438 2018-09-19 14:05:22 "user100" nue-ws-112 80 GET /deleteobject.htm _hjax=true&id=17849

Hi Stephan,

Is there a more audit-kind of log file that could be reviewed?

This topic started in the SpiceWorks forum and we redirected it here. There are a few people that already expressed their interest in it, including myself.

We have e.g. a Junior Admin here that is taking on more and more responsibilities, including PRTG. What we are after is pretty much a summary report - can be a simple website in PRTG - that shows:

When - Who - Object and What changed / happened

The webserver log is to be read in interpreted - but this is not easy when it comes to details like:

What sensor - this should be the whole path in the hierarchy What changes on the object - was it added - was it deleted - was it modified If it was modified - what changed, e.g.

  • limits for error/warning adjust from OLD to NEW
  • description changed from OLD to NEW

On top even events like PAUSED - ACK - RESUME etc. would be important to see in the AUDIT LOG

Pretty sure you see where this is going. This would be a really helpful feature - call it AUDIT LOG

Caught myself several times discovering even more experienced peers changing things they should have changed..
