Go runtime metrics

Collection of runtime metrics is enabled by default. To disable, refer to the option SW_APM_RUNTIME_METRICS in Configure the Go Library.

APM Go Library versions 1.3.0 and later

OTel semantic Go runtime metrics are collected by the runtime instrumentation bundled by the APM Go library. The metrics are all prefixed with go.*.

The metric names and attributes are subject to change due to unstable semantic conventions.

APM Go Library versions earlier than 1.3.2

No pre-built dashboard is available for these legacy metrics.

The legacy Go runtime metrics are gathered from the standard library’s runtime package and reported by the library at an interval.

Metric	Description
trace.go.runtime.*	Go runtime statistics data, including number of goroutines and number of Cgo calls.
