merlimat opened a new pull request, #3968: URL: https://github.com/apache/bookkeeper/pull/3968
### Motivation Added support for collecting and exporting BK metrics through OpenTelemetry SDK. The instruments are using counters and histogram. Summaries with pre-computed quantiles are not used anymore. Histograms have a much lower overhead in the bookie process. The SDK is set to use the autoconfigure. The exporter can be configured through env variables as described in https://github.com/open-telemetry/opentelemetry-java/blob/main/sdk-extensions/autoconfigure/README.md eg: simplest case to export in Prometheus format: ``` OTEL_METRICS_EXPORTER=prometheus ``` This will make the metrics available on `http://0.0.0.0:9464/metrics` -- This is an automated message from the Apache Git Service.
