Add Logs Capture feature #10156

jpbempel · 2025-12-10T13:16:47Z

What Does This Do

Add logs capture based on log framework instrumentation that hooks when log event are generated to be written. Log events are sent to Logs backend through Datadog agent's Event Platform (Evp) proxy. We are reusing a previous infrastructure used for uploading logs for CI Visibility (see #7082).
We are adding support for Logback.
This feature is opt-in through DD_LOGS_CAPTURE_ENABLED config. Logs are sent as structured log layout and allow to add any additional attributes. For now we are adding directly trace correlation ids (traceId and spanId) and give the logs injection feature for free and without any setup on the log framework side.
Smoke tests are based on Logs Injection tests.

Motivation

On-boarding Logs easily through tracer that are already installed through SSI

Add logs capture based on log framework instrumentation that hooks when log event are generated to be written. Log events are sent to Logs backend through Datadog agent's Event Platform (Evp) proxy. We are reusing a previous infrastructure used for uploading logs for CI Visibility (see #7082). We are adding support for Logback. This feature is opt-in through DD_LOGS_CAPTURE_ENABLED config. Logs are sent as structured log layout and allow to add any additional attributes. For now we are adding directly trace correlation ids (traceId and spanId) and give the logs injection feature for free and without any setup on the log framework side. Smoke tests are based on Logs Injection tests.
