Figure out what solution that we should use for our servers.
- Alert via email (to our "drift"-address)
- Monitor if a server is not reachable (for a given period of time)
- May or may not be needed since we have DownNotifier
- Abnormal usage of resources
- E.g. high CPU usage for an extended period of time indicates that something is wrong
- Preferably with the option to automatically shut down the server
- Low disk space remaining
These haven't been checked against requirements.
