A few network points to ping to ensure connectivity throughout my system. Scheduled notification windows (for example, during work hours I don't want my phone pinged unless it's everything going offline. Off hours I do. Secondary notifications if problem persists to other users, or in the event of many triggers. That sort of thing). Sensitivity settings (If web server 1 shows down for 5 min, that's not a big deal. Another one if it doesn't respond to repeated queries within 1 minute is a big deal) A Weekly summary of issues would be nice. (especially the 'well it was down for a short bit but we didn't notify as per settings')

I DO have detailed internal monitoring of our systems  but sometimes that is not entirely useful, due to the fact that there are a few 'single points of failure' within our network/notification system, not to mention if the monitor itself goes offline it's not exactly going to be able to tell me about it. (and that happened once, right before the mail server decided to stop receiving mail).

I'll throw another into the list:

They have some nice features and monitoring over IPv4 and IPv6.
