SmartThings is a platform that connects users with multiple third-party applications. Like many modern systems, we depend on many systems we cannot control. By examining client-side errors in our configuration editor, we can see who is having problems in- and out-side of our platform. Using TrackJS monitoring tools as the linchpin to tie together observability metrics, SmartThings was able to grow platform partnerships by understanding third-party outages, exceptions, and misconfigurations in real-time. Learn how you can combine observability tools, like TrackJS, to build metrics unique to your system problems.
