[Observium] alert checker for specific ping probes

Hi, I have a bunch of ping probes and I would like to write an alert for some (but not all). Since the hostname is the same for all, how can I differentiate between them in an alert checker...for example, I want to alert on this: [cid:image001.jpg@01DA551D.A2E6D3E0]

But not this: [cid:image002.jpg@01DA551D.A2E6D3E0]

thanks
