Heartbeat check against websocket URL

Hi,

Is there a way I can check my webservice's websocket's "heartbeat"? I just want heartbeat to be able to connect to a websocket URL and verify a JSON response.

I'm currently trying this but its failing

- type: http
  name: 'Websocket Check'
  schedule: '@every 5s'
  urls: ["http://myserver:80/myservice/wsendpoint"]
  check.request:
    headers:
      'Pragma': 'no-cache'
      'Origin': 'http://myserver'
      'Accept-Encoding': 'gzip, deflate'
      'Accept-Language': 'en-US,en;q=0.9'
      'Sec-WebSocket-Key': 'YzcC7Fy1g/mlss3qO2Kz1Q=='
      'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.110 Safari/537.36'
      'Upgrade': 'websocket'
      'Sec-WebSocket-Extension': 'permessage-deflate; client_max_window_bits'
      'Cache-Control': 'no-cache' 
      'Connection': 'Upgrade'
      Sec-WebSocket-Version': '13'

Note: I got this parameters from my chrome - by right clicking on the websocket URL and copying as CURL

Note2: If I use the CURL command in my bash (and as long as I replace the 'ws://' part with 'http://', it works). But the same settings though dont work with heartbeat

Any thoughts?

Thanks,
Franz

Sorry for the late reply, but glad you found an answer!

We should, however, make this easier to configure, ideally we'd just have a websocket mode. Thanks for this awesome post :slight_smile:
