3 tips for setting up PRTG monitoring
Start big
The PRTG Auto-Discovery function is launched upon installation. It searches for available devices within a certain range of IP addresses and sets up an initial monitoring environment. This facilitates the configuration and maintenance of your monitoring.
Narrow down
With the 100-sensor edition of PRTG, you’ll have to delete most of the sensors created by the automatic network discovery. For basic monitoring, use most of your sensors for essential servers, routers, and switches.
