Minerstat, especially with their OS helped me manage my rigs easier and remotely. The paid version with alarms, triggers and Telegram bot is worth the price! Come on, if you're mining it pays itself, since it saves you from errors and downtime.

good service, i have used Minerstat for about 11 months now. so far i haven´t run into any issues

Minerstat gives me a good centralized management dashboard to view and control all my miners. It provides me with a good birds eye view of all my rigs in one view. It allows me to drill down and make custom configurations to one or many rigs at a time as well. There are many more features, you have to try it for yourself.
