Agreed. I don't think my company would use this at the moment until it's proven service that has a good track record and a SLA (what's your up-time guarantee?). That said, I'd use it for my personal projects but not for $19/month. I'd pay about $1/month per monitor.

I get what you're saying, but I think you're being overly skeptical. If you've already got a system for monitoring tasks in place, there's no reason you couldn't run both. And if you don't have a system in place, then if it fails you'll be no worse off than having never signed up.

I think most SLAs for these types of services are mostly pointless anyway. If something important to your business goes down, are you really going to be worried about whether or not you have to pay the $19?

RE: SLA... the use case is more "I want to know sooner than later that something didn't happen" than "Something didn't happen this minute, I want to know NOW!". If and when we go down, your task won't be able to check in and we'll end up sending you a false "positive" which is better than not knowing at all when something fails.

Actually, false positives with alarms are really, really bad - I will start to ignore them very quickly if they're not reliable indicators of an actual problem.

EDIT: If you have reasonable default tolerances or the ability to set tolerances on tasks, I'm pretty interested in trying it out - do you integrate or have plans to integrate with pagerduty, or do you simply fire off an email?

[r38y]

What I'm saying is, in the rare chance we are down and your service can't check in, that one time we would send a false positive. We wouldn't be flapping between off and on sending you a lot of false positives. The resolution on our checks is so large (the smallest is an hour) that we won't be flooding you with emails in any case.

We don't replace something like monit to make sure your process continues to run, we are validation that one-off periodic things run... things that are easy to forget about but are important.

[ericd]

Yeah, I'm not terribly worried by that kind of failure, if that happens, a bunch of other things have already gone wrong. I would like something to keep track of all processes, though, that can back up monit. Good to know it's got some slack in the tolerances, I'll give it a try.
