Dependency of two performance counters




We configured two custom performance counters for a dedicated software to monitore on the one hand the amount of licensed users and on the other hand the amount of logged in users (the license model is concurrent).

So it is possible to configure a dependency with a specific threshold? For example i have licensed 11 users and when a difference of 2 is reached (9 logged in users) i want to get the Sensor is set to error status

Thank you for your message.

Regarding what you would like to achieve, I would recommend to use the Sensor Factory sensor to calculate the difference between the two channel values reported by their corresponding sensor.

Here is the manual of the sensor: https://www.paessler.com/manuals/prtg/sensor_factory_sensor

The formula should then looks like the following:

#1:License left
( channel(Sensor1_ID,ChannelID) - channel(Sensor2_ID,ChannelID) )

You can then configure limits in the channel settings and trigger notification template.

If you have questions, let us know.
