Project description

Superhooks

Superhooks is a supervisor "event listener" that sends events from processes that run under supervisor to predefined web hooks. When superhooks receives an event, it sends a message notification to a configured URL.

Installation

pip install superhooks

$ superhooks  -u http://localhost:8090/ -e STARTING,RUNNING,BACKOFF,STOPPING,FATAL,EXITED,STOPPED,UNKNOWN -d "a^b^^c^d" -H "p^q^^r^s" 

Options

-u URL, --url=http://localhost:8090/

Post the payload to the url with http POST

-d DATA, --data=a^b^^c^d post body data as key value pair items are separated by ^^ and key and values are separated by ^

-H HEADERS, --headers=p^q^^r^s request headers with as key value pair items are separated by ^^ and key and values are separated by ^

-e EVENTS, --event=EVENTS

The Supervisor Process State event(s) to listen for. It can be any, one of, or all of STARTING, RUNNING, BACKOFF, STOPPING, EXITED, STOPPED, UNKNOWN.

Configuration

An [eventlistener:x] section must be placed in supervisord.conf in order for superhooks to do its work. See the “Events” chapter in the Supervisor manual for more information about event listeners.

The following example assume that superhooks is on your system PATH.

[eventlistener:superhooks]
command=python /usr/local/bin/superhooks -u http://localhost:8090/ -e BACKOFF,FATAL,EXITED,UNKNOWN -d "a^b^^c^d" -H "p^q^^r^s"
events=PROCESS_STATE,TICK_60

The above configuration will produce following payload for an crashing process named envoy
