Yes, our servers send a response code. I already have a watchdog of sorts built in to my node-red flow that will reboot the box if the node-red flow is unable to deliver messages for 4 hours. It also delivers lora stats every 5 minutes as a heartbeat.
Unfortunately, on several occasions we’ve found that the conduit continued to update devicehq, but was no longer delivering data to our api and my node-red watchdog didn’t activate. Nothing was written to the node-red logs either, so I concluded that node-red itself either hung up or crashed.
We’re using 1.6.2 which does have log rotation for node-red. I haven’t tried 1.6.4 yet, but I hope they didn’t un-fix the node-red log rotation. We had previous issues with the node-red log getting too big.
