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

I love the sleek feel to the web UI, compared to other mining platforms. I also very much enjoy that i can have all of my windows rigs in the same view my linux rigs. Price is great too!
