We are working on a brand new version of Observu. It will aim for high quality monitoring that combines external availability and response time monitoring with statistics collected from the servers itself.
Features will include SMS and phone notifications, API access, customizable rules and a great dashboard.
We are currently in private beta and are working to get everyone on board in 2012.
You can already Follow Observu On Twitter and visit our blog.
We invite you to contact us at support@observu.com, if you've got inspiring ideas about site and server monitoring or just want to ask a question. You can also post suggestions on our feedback forum.
