Ability To Add a single Sensor to Multiple Devices Without template

Hello,

Thank you for using our PRTG Network Monitor and contacting Paessler TechSupport.

You can add one sensor to multiple existing devices with a Device Template, that only contains the single sensor, and the Auto-Discovery. The steps would be the following:

1. Create an empty device with only the sensor you want to add on the other devices.
2. Create a Device Template from this "prototype device".
3. Use Multi-Edit to set this Device Template on all existing devices (which should get the sensors) in their "Sensor Management"-options.
4. Run the Auto-Discovery on those devices. To this, just go to the "Management"-View ("Devices"->"Management"-Tab) and pick all the devices you want/need (hold the CTRL-Key on your keyboard to select multiple devices at once) and then similar to the Multi-Edit pick "Run Auto-Discovery" from the context menu.

You could also use a script based approach to add sensors, with the catch though that you can only clone existing sensors with the API. You cannot completely create new sensors with the API. Of course cloning would fit here, it would need a list of device ID (the targets then) for the script. Behind the scenes the approach is similar to using device templates, in both cases you'll use a prototype, one is using a graphical interface though and the other scripting. That's then really up to you.

Best regards.
