The killer feature I need is heartbeat so I can make some device send a request every 5 min and if it’s not sent then it is down. Currently using UptimeRobot for this.
I haven’t used the product but I remember reading about if here on Hacker News: https://news.ycombinator.com/item?id=31488910
I think that could also be helpful for ensuring scheduled jobs are running fine. I can see myself wanting this at some point.
