Would just like to be notified when the primary circuit goes down and the backup circuit comes up.

you need two sensors that monitor your two circuits and then use a sensor factory sensor wit the Define Sensor Status—status() Function

Sorry, looked over the doc but I dont get it , do you have a better example of this?

Thanks, Louis

hallo,

you would need two sensors that show the status of your circuit. e.g . two http sensors that monitor an external website.

One of the sensors needs to use your normal Internet connection and would be green most of the time (would only turn red if your main Internet connection fails)

The other sensor would have to use your second internet connection and would be red for most of the time.

you can then use a sensor factory sensor and the status function with this definition

status(2031) NOT status(2044)

This will change the factory sensor to a Down status if the sensor with ID 2031 is Down , but the sensor with ID 2044 is not in a Down status. Otherwise the factory sensor will show an Up status.

where the sensor with the id 2031 would be the sensor monitoring your main connection and the sensor with the ID 2044 would be the sensor monitoring your second connection.

your sensor IDs would of course be different.

How do I tie the http monitor to an interface?

hallo, for one sensor you could use a proxy that you setup to use either your main circuit or the fail over, and the other sensor does not use the proxy.

Or you place one of the sensors on a remote probe that uses the second circuit as a gateway.
