I want to get ping sensor, that will only collect information about the availability of a device and will not change its own state. Is this possible?


A sensor always indicates the current status of a device for the aspect it is monitoring. For example, if a device is not reachable, a PING sensor (the one built into PRTG) on this device will change to a red "error" state to indicate the down status. You cannot change this, because otherwise the sensor would show incorrect information.


You can, however, disable all notification triggers for this sensor. If you do and a device is down, the according sensor will show a "red" error status, but you will not get any email, sms or other notifications about the failure.


To disable all notification triggers for a sensor, please

  • go to the sensor's settings (right-click, Settings...) and
  • choose the Notifications tab. There,
  • disable the Inherit trigger(s) from parent object(s) option and
  • delete all defined triggers.

Please see manual section Notifications for more details.


Alternatively, there's a custom ping sensor from the third-party-supplier PRTG Tools Family available (PingWarning.exe) that goes into a Warning status (instead of a Down status) if the device is down.0

You can find the sensor at http://www.prtgtoolsfamily.com/us/downloads/sensors.html.
