Real User Monitoring With a Splash of OpenTelemetry
You're probably familiar with the concept of real user monitoring (RUM) and how it's used to monitor websites or mobile applications.

These SDKs then hook into the JS runtime, the browser itself, or various system APIs in order to measure performance.
