OpenTelemetry 指标导出器 - 标准输出

Status: Stable

"Standard output" Metrics Exporter is a Push Metric Exporter which outputs the metrics to stdout/console.

OpenTelemetry SDK authors MAY choose the best idiomatic name for their language. For example, ConsoleExporter, StdoutExporter, StreamExporter, etc.

"Standard output" Metrics Exporter MUST support both Cumulative and Delta Temporality.

If a language provides a mechanism to automatically configure a MetricReader to pair with the associated exporter (e.g., using the OTEL_METRICS_EXPORTER environment variable), by default the exporter MUST be paired with a periodic exporting MetricReader with a default exportIntervalMilliseconds of 10000.
