statusServer web sockets python example

statusServer settings configures Trunk Recorder to send status messages regularly and on events to a server for processing/output.

It uses the websockets protocol, and is in the following json format https://github.com/robotastic/trunk-recorder/blob/master/docs/notes/STATUS-JSON.md

Here is a simple python script example that simple print the messages received from trunk recorder. From here you can do what ever you need with the data.

add to config:

"statusServer":"ws://127.0.0.1:8000/"

run:

#!/usr/bin/env python3

import asyncio
import websockets
import json

async def echo(websocket, path):
    while True:
        message = await websocket.recv()
        print(message) #print every message, comment to filter

        data = json.loads(message)

        #if data['type'] == 'recorder':#uncomment to filter, adjust as needed
           #print(message)#uncomment to filter

start_server = websockets.serve(echo, "127.0.0.1", 8000)

asyncio.get_event_loop().run_until_complete(start_server)
asyncio.get_event_loop().run_forever()
