[Observium] alert checker for a ping probe

Hi, I have some ping probes and a generic alert check that alerts if any of the ping probes fail like this: [cid:image001.jpg@01D9AB6C.2065CB20]

But..now I need to have 2 different alerts based on the name in the ping probe....

How can I write an alert check to distinguish 2 different alert probes?

Thanks

Tony
