This feature is available as part of the Honeycomb Enterprise plan.
The OpenTelemetry Metrics API is in “draft” status, targeting completion in the second half of 2021. As a result, all OpenTelemetry Metrics SDKs are still subject to breaking changes. Until then, for production applications, we recommend instrumenting your application with a Prometheus client library and using OpenTelemetry Collector to scrape those metrics and send them to Honeycomb. Learn more about receiving metrics from Prometheus.
OpenTelemetry SDKs have been implemented for various languages. They can collect a standard set of runtime metrics (for instance, information about memory usage, garbage collection, or parallelization). In some cases, they also instrument commonly used frameworks and libraries. They also provide an API allowing your application to custom metrics. OpenTelemetry SDKs can then be configured to send metrics to Honeycomb over OpenTelemetry Line Protocol (OTLP).
Refer to the OpenTelemetry SDK Documentation for your environment for details on how to instrument your application. You’ll need to enable an OTLP (OpenTelemetry Line Protocol) exporter and it should have:
x-honeycomb-teamheader with an API key that has write permissions
x-honeycomb-datasetheader with the name of the dataset you would like to send metrics to
