<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> 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 that shows similar behavior in your sensors. The analysis is completely automated and sensor type agnostic. It is based on mathematics and fuzzy logic. This feature helps you find interconnections in your network that 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 or turn it off in System Administration—Monitoring. You can also enable or disable the similarity analysis for specific probes, groups, and devices and specify inheritance in the corresponding object settings, section Automatic Monitoring Analysis.

There are two options to view similar sensors:

• The overview page of sensors contains a similar sensors section. PRTG lists channels there that 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)

Probe, group, device, and sensor pages have tabs that you can use to navigate between the different options. For example, you can view your network's status, view monitoring results, or change settings.

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

PRTG only shows similar sensors here when channels have at least 85% similarity. Furthermore, the analysis saves up to 15 entries per sensor at most.

The similar sensors section provides the following information:

PRTG does not show the similar sensors section when the analysis is off or when you have exceeded 1,000 sensors and selected the automatic analysis depth option. You will see a notice in this case.

Similar Sensors Overview (Sensors Menu)

This page shows the results of the similar sensors analysis from the entire monitoring database. PRTG lists all channels with similarities to another one here. On the table top, you have several filter options to display similar sensors as you need it. Choose the object of interest, the degree of similarity, and if you want to display back references. For more details, see also section Working with Table Lists.

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

PRTG does not show the similar sensors overview option in the main menu if you turned off the analysis or if you have exceeded 1,000 sensors and selected the automatic analysis depth option.
