When we deployed we didn't know about bluepill and wrote a quick script. Stormcloud does a fair number of other things such as tracking min/max lifetime of children and it attempts to sort out why the process died in the first place.

Thanks for the bluepill link though, we'll take a look at it and might consider a rewrite of our internal tool at some point.

I'd like to open source Stormcloud when it becomes more accessible. Unfortunately, it's laden with internal dependencies to our monitoring systems, and not publicly consumable at the moment.
