Good point. I was only thinking of uptime in the sense of 'seconds
since last reboot'. Uptime in the sense of 'availability', ie. the
opposite of downtime, might well be closer what the original question
was about.

tSmoke is actually included in the 2.0rc5 tarball, since it needed a
few modifications for 2.0 compatibility.

This should be implemented so that it's easy to add new 'uptime
plugins'. An SNMP query for sysUptime and an ability to run an external
command are the first things that come to mind, but perhaps there are
others...  like how long a DNS name has resolved to the same IP
address, or a given URL has contained the same HTML code. Ideas

Hm, as I think of these now, the latter seem probe-specific. Maybe a
probe should be able to define its own uptime plugins in addition to
the generic ones...
