Connect Logs and Traces

Connect your logs and traces to correlate them in Datadog

The correlation between Datadog APM and Datadog Log Management is improved by the injection of trace IDs, span IDs, env, service, and version as attributes in your logs. With these fields you can find the exact logs associated with a specific service and version, or all logs correlated to an observed trace.

It is recommended to configure your application’s tracer with DD_ENV, DD_SERVICE, and DD_VERSION. This will provide the best experience for adding env, service, and version.

Before correlating traces with logs, ensure your logs are either sent as JSON, or parsed by the proper language level log processor. Your language level logs must be turned into Datadog attributes in order for traces and logs correlation to work.

MCaaS Environment Variables

MCaaS recommends the applications to utilize MCaaS provided environment variables when logging for easier tracing. Please see here for more information.
