Have you tested this monitor on a trading bot such as Gunbot? And how does it perform in this scenario?
Does it come with a web interface?
I haven't, but you can run Gunbot easily with processWatchdog, all the same process. Just you need to disable heartbeat monitoring by setting heartbeat_interval = 0, so processWatchdog wont expect any heartbeat messages from Gunbot. Please feel free to share if you run Gunbot with processWatchdog.
It does not have a web interface yet, a log file and stats file is what you can check if all good or not.
