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. View the README on the homepage for more details. Install notes: On client installs where you may not want to install the server component, configure like:

cabal configure -fno-server

On client installs where you may not want to install the client component, configure like:

cabal configure -fno-client
