Changing the number of entries in Most Used Sensor Types

PRTG automatically shows the most used sensor types in the Add Sensor dialog to recommend sensors for a device. By default, the number of sensor entries in this section is 10 (if you have used enough sensors that are applicable to the device).

If you want to adjust the number of sensor types that are shown, you can use a registry key option. This also allows you to completely hide the Most Used Sensor Types section, or to show more than 10 sensor entries.

Note: We recommend that you always back up your system before you make changes to the Windows registry.

Steps to take

1. Open the registry editor and go to the following key:
   1. On a 64-bit Windows system, go to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Paessler\PRTG Network Monitor\Server\Core\
   2. On a 32-bit Windows system, go to HKEY_LOCAL_MACHINE\SOFTWARE\Paessler\PRTG Network Monitor\Server\Core\
2. Create a new DWORD: In the current path, right-click, select New | DWORD Value, and name the new value MostUsedTypes.
3. Set the value to the desired number. Right-click MostUsedTypes and select Modify… In the value field, enter the number of sensors you want to display. Confirm with Ok. The number you provide there corresponds to the number of sensors shown under Most Used Sensor Types. If you define 0, this information is completely hidden.
4. Restart the PRTG core server so that the changes take effect.

After this registry modification, PRTG shows as many sensor types under Most Used Sensor Types in the Add Sensor dialog as you defined in the DWORD value field.
