metric

var Component = &component.Component{
	Name: "runner.metric",
	Dependencies: component.Components{
		runner.Component,
	},
	Init: component.StepFunc(func(container container.Container) error {
		return container.Provide(NewMetric)
	}),
	PreExecute: component.StepFunc(func(container container.Container) error {
		return container.Invoke(func(r runner.Runner, middleware *Metric) {
			r.Use(middleware)
		})
	}),
}

Component is a ready-to-use Compogo component that automatically adds Prometheus metrics middleware to the application's runner.

It depends on runner.Component and registers itself during the PreRun phase. The exported metrics follow the naming convention:

compogo_runner_task{app="<app-name>"}

Usage:

compogo.WithComponents(
    runner.Component,
    metric.Component,  // ← adds Prometheus metrics to all tasks
)
