Vigilance is a dead man's switch (See https://en.wikipedia.org/wiki/Dead_man%27s_switch)
(or vigilance switch). You define named @watches that you expect to happen
and how long to wait inbetween before it's time to worry. You then instrument
your periodical tasks, whatever they are, to report to vigilance via a simple
HTTP POST or with the included client. You can then
configure notifications that will fire when a watch fails
to check in.
