Autometrics is an open-source observability project focused on instrumenting application functions. Its homepage describes decorators, macros and wrappers that add request-rate, error-rate and latency metrics, then generate queries to help developers inspect those measurements. The emphasis is on connecting a function in source code with useful production signals rather than starting from an empty monitoring dashboard.
The project includes an Explorer for investigating functions, service-level objectives and alerts, along with a command-line interface for viewing metrics locally. It describes defining service-level objectives in source code, generating Prometheus queries and tracking application versions to help identify problematic deployments. A GitHub Action and Grafana dashboards are also part of the published feature set.
Autometrics says it exports Prometheus-compatible metrics and works with OpenTelemetry, while its Explorer and Slack application use the Prometheus API. Adopting the tooling still requires suitable instrumentation and a metrics backend; an open-source framework does not remove the work of operating or securing that infrastructure. Developers should inspect the language-specific libraries and deployment documentation for their environment. Its appeal is a function-centered approach that makes it easier to connect code, measurements and alert thresholds during debugging.
