PRTG Manual: Similar Sensors

With PRTG you can detect relationships between different components in your network. This function is called similar sensors analysis, a heuristic calculation showing similar behavior of your sensors. The analysis is completely automated and sensor type agnostic. It is based on mathematics and fuzzy logic. This feature will help you to find interconnections in your network you were not aware of and optimizes your sensor usage by tracking redundant monitoring of some aspects of your system.

You can adjust the depth of similar sensors analysis in System Administration—System and Website.

There are two possibilities to view similar sensors:

• Each sensor's overview page contains a similar sensors section. PRTG lists channels there which show similarities to channels of the current sensor.
• In addition, you can call a similar sensors overview page via Sensors | Similar Sensors Overview from the main menu.

Similar Sensors (Sensor Overview Tab)

Pages of probes, groups, device, and sensors have a tab-like interface. Using the tabs you can navigate through various sub-pages of an object in order to show your network's status, view monitoring results, or change settings.

On the overview tab of a sensor, PRTG lists channels which show similarities to channels of the currently selected sensor. The table will be empty if PRTG detects no similarities regarding the selected sensor.

The similar sensors section provides the following information:

Similar Sensors Overview (Sensors Menu)

This page shows the results of the similar sensors analysis from the entire monitoring database. PRTG will list all channels with similarities to another one here.

You can sort the list by clicking on the column headers. The similar sensors overview page provides the following information:
