Functions

func InstrumentRouteFunc

func InstrumentRouteFunc(verb, resource, subresource, scope string, routeFunc restful.RouteFunction) restful.RouteFunction

InstrumentRouteFunc works like Prometheus' InstrumentHandlerFunc but wraps the go-restful RouteFunction instead of a HandlerFunc

func Monitor

func Monitor(verb, resource, subresource, scope, client, contentType string, httpCode, respSize int, reqStart time.Time)

Monitor records a request to the apiserver endpoints that follow the Kubernetes API conventions. verb must be uppercase to be backwards compatible with existing monitoring tooling.

func MonitorRequest

func MonitorRequest(request *http.Request, verb, resource, subresource, scope, contentType string, httpCode, respSize int, reqStart time.Time)

MonitorRequest handles standard transformations for client and the reported verb and then invokes Monitor to record a request. verb must be uppercase to be backwards compatible with existing monitoring tooling.

func Register

func Register()

Register all metrics.

func Reset

func Reset()
