SolarWinds Pingdom provides valuable monitoring capabilities for IT systems and applications. It presents an accessible, easily adaptable and customizable architecture to any user. It has an active user community and provides great customer support services. It helps organizations to ensure the availability and performance of their online assets and applications.

It make easy check the online status of any server, including, reading data from json endpoints. It's a must have.

1. We monitor many of their nodes not working for at least 5-10 mins/day which provides many false positives 2. The few time we needed tech support answers were slow and they did not provide proper answers/solutions to the issues we had (broken dashboards, missing checks etc)

I have been using multiple downtime monitoring systems together, pingdom has been reliable. Sometimes using JavaScript seems to be a better solution in monitoring than using DNS. Unfortunately, it no longer offers free version unless you have been with them for a while. I love the UI on their mobile app too, though downtime notification seems a little buggy sometimes.

Super easy to use and insightful read and make sense of what is going on - on your site
