Just wanted to cross-post this in case people are looking in this thread for a way to monitor and restart streams that have stopped:

https://forum.magicmirror.builders/topic/11828/short-script-to-monitor-and-restart-your-mmm-rtspstreams

Here is a super short Python script that checks the status of your streams using pm2, then if it detects a stream is down, it restarts the streams. Not elegant, but it works.

import os
if "stopped" in os.popen("pm2 status | grep \"stopped\"").read():
    os.popen("pm2 start 1 2 3 4")

I saved it as streamMonitor.py in my home directory. I run it once per minute using crontab. This is the entry I put in:

* * * * * python3 ~/streamMonitor.py

Here is the script in action:

And here is the crontab job:

Okay, looks like something with my npm was broken. It was working before, so I think installing this module or Homebridge did it. Attempting to fix.

Excellent module!

Got everything working fairly easily. I am attempting to add my own switches, but the issues I am having is that the “on_cmd” and “off_cmd” do not use npm correctly. Any ideas? This is the error it’s throwing. Didn’t have luck Googling.

did you ever find a solution?

Does anyone know if it’s possible to use moduleOffset from within a single stream (stream3)? I couldn’t get it to work.

I have three streams going. The first two are side-by-side, but the third is centered under them. I would like the third to be left-justified. Any ideas?
