Field Agent for Dead Man’s Snitch is the perfect intel-gathering companion for your snitches.
Field Agent is a command line utility whose job is to gather extra data on your critical tasks, package it up, and report it back to Dead Man's Snitch. This means new possibilities for alerting and debugging of issues while maintaining the simplicity we are so proud of at Dead Man's Snitch.
Field Agent is designed to wrap the execution of a script or command. This allows it to gather data about your job like timing information and exit codes. The first parameter is the unique token you can get from your Snitch's setup page. Anything after that will be executed as the command or script you want to run.
It's important that your scripts exit cleanly (e.g.
exit 0) if
they run without an error. If they do error they should exit with any
other status code (
exit 1 is pretty common).
