How do I purge deleted sensors' data from my database?



Our database size is growing quite large. There have been many experimental sensors which has taken it's toll on our database size.

Not having a comprehensive list of deleted sensors, I was wondering if there was a way that PRTG purges its data base from non current data.

Dear Karen,

in PRTG's web interface, please go to the System Setup. In the System, Website, and Web Server Settings tab, you can set the Data Purging Limits for Historic Sensor Data in the respective section. The settings are valid for all sensors.

Is there a way to only do this for deleted sensors? Or more importantly, what data am I cropping from my active sensors as well.
