We (ISP) use several mechanisms:
* a local watchdog shell script that is called by cron minutely and that
- checks "ps cax" if every process is there else it restarts it
- checks if the disk is getting full
- checks if the load is abnormal high
- does some host dependent stuff
- sends a "i'm alive" message via syslog
* a central syslog host
- with "logcheck" for a dozend servers and routers
- that checks if the "i'm alive" message of every server is there.
Else it's very probable that the server is under too high load
or about to crash (or the admin forgot to activate the
watchdog)
* a central netsaint (aka nagios) for a general overview and to send mails
to an SMS gateway to contact the 24/7 techies.
Apart from that we have here and there some little things like nightly
apt-get dry-runs that inform us about security updates that would be
installable which we have not yet done (only in times like now where
stable is quite unchanging).
