Types

Counters tracks per-tenant request counts + a global aggregate.

func New

func New() *Counters

New returns a fresh Counters.

func (*Counters) Inc

func (c *Counters) Inc(tenant string, statusCode int)

Inc records one request for tenant (empty = unresolved). statusCode >= 500 also increments the error counter.

func (c *Counters) Snapshot() map[string]int64

Snapshot returns a copy of the current totals (for tests).

type StatusRecorder

type StatusRecorder struct {
	http.ResponseWriter
	Status int

StatusRecorder wraps http.ResponseWriter to capture the status code for the Counters.Inc call.

func (*StatusRecorder) WriteHeader

func (r *StatusRecorder) WriteHeader(code int)
