The best part is it can easily monitor all your servers in one dashboard, so you don't have to go through each server individually or use different tools like Pingdom etc., which makes things easy when managing multiple web apps using many microservices architecture pattern with Docker containers running at various locations/environments across data centers! It's not free but their support team are amazing & always there if needed (which I've never encountered).
You could also do some customizations as per requirement by yourself without any issues from them unlike other solutions where they often charge additional fees after initial trial period of 30 days!! Also sometimes we need more control over our application logs than what comes out-of box via Loggly integration - hence this came handy while integrating logging into my app that was built previously before moving onto AWS EKS + ELK stack :) We were solving problem related logging within an eCommerce website hosted.
