implements the OpenTelemetry OTLP Protocol. This API
is designed for use with applications that are instrumented by using one of

OpenTelemetry is a Google Cloud-supported open source project with Google Cloud
engineers staffed to ensure support for ingesting and visualizing your
telemetry.

The Telemetry API service, whose service name is telemetry.googleapis.com,
is a VPC Service Controls-supported service. Any VPC Service Controls restrictions
that you create for the Telemetry API service apply
only to that service. Those restrictions don't apply to any
other services, including those like the cloudtrace.googleapis.com service,
which can also ingest trace data.
