Custom Metrics (JMX, Golang expvar, Prometheus, statsd or many other), APM and Opentracing are different approaches on how to instrument code in order to monitor health, performance and troubleshoot your application more easily.

Since we made Datadog APM generally available last year, we have continually added new features and support for new languages and frameworks to ensure that you can monitor every aspect of application performance. Datadog APM helps companies such as Airbnb, Square, and Zendesk to optimize application performance and deliver top-notch customer experiences.

Here at the Hive, we know that there’s nothing like getting your hands on something to see what using it to solve a problem is really like. In July, we launched the Gatekeeper tour, which walks you through the process of solving a real outage we experienced, using Honeycomb. That’s why we’re excited to launch a new place for you to play: the Tracing Tour at http://play.honeycomb.io.
