When rackspace launched cloud monitoring I was really interested, especially since leaving AWS... I kind of felt a bit blind to what my servers were doing.
By default, the monitoring service sends you emails for up/down alarms... just what we need more emails! ... So I have started to write an alarm console which is a compatible webhook for their API.... i.e. you can send alarms to it!
My Webhook is called [rx]Alarm... rx as in receive :)
This may end up being yet-another-project-I-don't-finish ... or it maybe not, only time will tell!
