Changing the Number of Entries in “Most Used Sensor Types”

PRTG automatically shows the most used sensor types in the “Add Sensor” dialog to give you a recommendation which sensors to create on a device. By default, the number of sensor entries in this section is 10 (if there are enough sensors used by now which are applicable for the current device). Which sensor types are displayed here is calculated specifically for each user on the PRTG instance.

However, if you want to adjust the number of sensor types which 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. It is also possible with this option to hide “most used sensor types” completely, or to increase the quantity.

Caution: Please back up your system before manipulating the Windows registry!

Steps to Go

1. Open the registry editor and navigate to the following key:
   1. On a 64-bit Windows system, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Paessler\PRTG Network Monitor\Server\Core\
   2. On a 32-bit Windows system, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Paessler\PRTG Network Monitor\Server\Core\
2. Create a new DWORD: in the current path, right-click, choose New | DWORD Value, and name the new value MostUsedTypes
3. Set the value to the desired number. Right-click on MostUsedTypes and select Modify… In the value field, enter the number of sensors you want to have displayed. Confirm with Ok. The number you provide here will correspond to the quantity of shown sensors under “Most Used Sensor Types”. If you define 0, this information will be hidden completely.
4. Reboot the server to activate the settings.

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