Tell me when "something" has happened (eg: another program has finished).
I created this utility because I had long running database scripts that I wanted a completion notification for. I had done this various ways in the past by using bash and other shell utilities. This program captures all of the features and behavior I wanted without having to script it from scratch again every time I needed it.
- can run a command, make an http call
- success/fail based on exit code
- watch an already running process (by pid)

- Socket related conditions: notify when we can connect to a socket, notify when a socket connection timesout, notify when a connection refused to a port (i.e. a service stops listening)
- HTTP Status related conditions: notify when a specific HTTP status code is returned for a GET or HEAD (404 - when something goes missing, or 200/201/202 when something exists.
- Alternate Notfication Options: HTTP POST, send an email (yes I know these can be implemented by short commands or shell scripts)
- Periodic Notifications: for very long running things we are waiting on, getting an intermediate notfication (i.e. "still running, started at XYZ, running for ELAPSED so far...", followed by a "Final" notification.
