heartbeat? monitor?

[CrankyCoder]

So last night I get home my billiards league and my raspberry pi gateway is acting up. I logged in so the network and all was fine. I checked the mqtt server and messages were flowing there too. I even checked and the mysgw process was running. But it was not relaying messages. I rebooted it and all was fine.

So I am curious about trying to monitor it so i can do that reset automatically and not have half my lights unavailable.

I was wondering about maybe monitoring for heartbeats?
maybe something like monitoring gw/+/255/3/0/21 and if i don't see anything for some time reset it. But I don't know how often heartbeat messages are sent.

Anyone else monitoring gateways? I haven't had this problem much, but was not happy to get the call from the wife saying she had to unplug stuff to turn off the lights lol

@crankycoder presumably gateway traffic will come to a complete stop in case of troubles.
In this case you can just monitor any mqtt messages coming from the gateway (something like gw/#). If no messages come in for x time, reboot the gw.

any idea how often heartbeat messages would be sent?
