OpenTelemetryExporterPrometheus

In this package, only one AbstractExporter is exported: the PrometheusExporter. With this exporter, one can use the Prometheus to view the Metrics.

OpenTelemetryExporterPrometheus.PrometheusExporter — Type
PrometheusExporter(; kw...)

Keyword arguments

  • host, the default value is read from the OTEL_EXPORTER_PROMETHEUS_HOST environment variable.
  • port, the default value is read from the OTEL_EXPORTER_PROMETHEUS_PORT environment variable.
  • resource_to_telemetry_conversion=false, if enabled, all the resource attributes will be converted to metric labels by default.
  • path="/metrics", the default url path.

Usage

r = MetricReader(PrometheusExporter())

Note that PrometheusExporter is a pull based exporter. There's no need to execute r() to update the metrics.
