google-cloud-trace-v2

https://github.com/googleapis/google-cloud-ruby

Sends application trace data to Stackdriver Trace for viewing. Trace data is collected for all App Engine applications by default. Trace data from other applications can be provided using this API. This library is used to interact with the Trace API directly. If you are looking to instrument your application for Stackdriver Trace, we recommend using OpenTelemetry. Note that google-cloud-trace-v2 is a version-specific client library. For most uses, we recommend installing the main client library google-cloud-trace instead. See the readme for more details.
