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 which sensors to create on 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 current device so far). The sensor types that are displayed here are specifically calculated for each PRTG user.

However, if you want to adjust the number of sensor types that are shown when adding a sensor, you can use a registry key option to centrally define how many sensors you want to see in the dialog. With this option, it is also possible to completely hide Most Used Sensor Types, or to increase the number.

Note: Always back up your system before manipulating 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 here will correspond to the number of shown sensors under Most Used Sensor Types. If you define 0, this information will be completely hidden.
4. Restart the server to activate the settings.

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