When trace data isn't automatically captured, you need to instrument
your application to collect this data.
You can instrument your application so that it collects
application-specific information. Several open-source
instrumentation frameworks let you collect metrics, logs, and
traces from your application and send that data to any vendor,
including Google Cloud. To instrument your application, we recommend that you use a
vendor-neutral instrumentation framework that is open source, such as
OpenTelemetry, instead of
vendor- and product-specific APIs or client libraries.
For information about instrumenting your applications by using
vendor-neutral instrumentation frameworks, see
Instrumentation and observability.
