Description

Currently, GoFr provides native support for exposing metrics in long-running services via /metrics endpoints. However, CLI applications or CronJobs (short-lived batch jobs) don’t have a persistent process, making it impossible to expose metrics directly.

To support observability for such workloads, GoFr should provide a mechanism to emit metrics from CLI applications in a way that integrates cleanly with Prometheus (or other monitoring systems).

Proposed Solution

• Add built-in support for Pushgateway integration:

  • Allow GoFr CLI applications to push job-level metrics (success, failure, duration, custom counters/gauges).

• Allow configuration through environment variables/flags (e.g., GOFR_METRICS_PUSHGATEWAY_URL).

• Support cleanup (optional) so old metrics don’t pile up.

Use Cases

• Kubernetes CronJobs that use GoFr CLI applications.
• CI/CD pipelines running GoFr-based tools.
• One-off admin scripts that need to report metrics.

Benefits

• Consistent observability across services and batch jobs.
• No need for custom logging → parsing pipelines.
• First-class Prometheus compatibility.
