Overview ¶

Package metrics owns chatz's Prometheus registry and the per-subsystem metric vectors. It is constructed once at boot (no package globals) and passed to the recorders that emit; the /metrics handler and the pprof mux are served on internal-only ports (never the public ingress).

Constants ¶

Types ¶

type Metrics ¶

type Metrics struct {
	// contains filtered or unexported fields
}

Metrics holds the registry and the metric vectors. Emit via the Record* methods; expose via Handler / PprofHandler.

func New ¶

func New() (*Metrics, error)

New builds the registry, registers the runtime + build-info collectors and the subsystem vectors, and returns the Metrics.

func (*Metrics) Handler ¶

func (m *Metrics) Handler() http.Handler

Handler serves the Prometheus exposition for the registry.

func (*Metrics) PprofHandler ¶

func (m *Metrics) PprofHandler() http.Handler

PprofHandler returns a mux with the net/http/pprof endpoints under /debug/pprof/. Internal-only: never mount on the public ingress.

func (*Metrics) RecordLLMRequest ¶

func (m *Metrics) RecordLLMRequest(
	service, stage, model, outcome string,
	dur time.Duration,
)

RecordLLMRequest records one LLM call's latency + count under the outcome.

func (*Metrics) RecordLLMTokens ¶

func (m *Metrics) RecordLLMTokens(
	service, stage, model, kind string,
	n int64,
)

RecordLLMTokens adds token counts for a call, by kind.
