autometrics

Overview ¶

Autometrics instruments annotated functions, and adds links in their doc comments to graphs of their live usage.

By default, `autometrics` generates metric collection code for usage with the Prometheus client library. If you want to use OpenTelemetry metrics instead (with a prometheus exporter for the metrics), pass the `--otel` flag to the invocation.

By default, when activating Service Level Objectives (SLOs) `autometrics` does not allow to use latency targets that are outside the default latencies defined in autometrics.DefBuckets. If you want to use custom latencies for your latency SLOs, pass the `--custom-latency` flag to the invocation.

It is meant to be used in a Go generator context. As such, it takes mandatory arguments in the form of environment variables. You can also control the base URL of the prometheus instance in doc comments with an environment variable.

Note: If you do not use the custom latencies in the SLO, the allowed latencies (in seconds) are in [autometrics.DefBuckets].

Usage: autometrics -f FILE_NAME -m MODULE_NAME [--prom_url PROMETHEUS_URL] [--otel] [--custom-latency]

Options:

-f FILE_NAME           File to transform. [env: GOFILE]
-m MODULE_NAME         Module containing the file to transform. [env: GOPACKAGE]
--prom_url PROMETHEUS_URL
                       Base URL of the Prometheus instance to generate links to. [default: http://localhost:9090, env: AM_PROMETHEUS_URL]
--otel                 Use [OpenTelemetry client library] to instrument code instead of default [Prometheus client library]. [default: false]
--custom-latency       Allow non-default latencies to be used in latency-based SLOs. [default: false]
