Functions

func Module

func Module() fx.Option

Module is a fx module that provides Prometheus registry and invokes registering metrics handler.

func ProvidePrometheusRegistry

func ProvidePrometheusRegistry(unmarshaller config.Unmarshaller) (*prometheus.Registry, error)

ProvidePrometheusRegistry creates a new Prometheus Registry and provides it via Fx. Metrics from the Registry are served on /metrics via the default http server of Fx application.

func RegisterMetricsHandler

func RegisterMetricsHandler(router *mux.Router, pr *prometheus.Registry)

RegisterMetricsHandler registers the metrics handler on the promhttp server.

Types

type MetricsConfig

type MetricsConfig struct {
	// Pedantic controls whether a pedantic registry is used. See <https://godoc.org/github.com/prometheus/client_golang/prometheus#NewPedanticRegistry>
	Pedantic bool `json:"pedantic" default:"false"`

	// EnableGoCollector controls whether the go collector is registered on startup. See <https://godoc.org/github.com/prometheus/client_golang/prometheus#NewGoCollector>
	EnableGoCollector bool `json:"enable_go_metrics" default:"false"`

	// EnableProcessCollector controls whether the process collector is registered on startup. See <https://godoc.org/github.com/prometheus/client_golang/prometheus#NewProcessCollector>
	EnableProcessCollector bool `json:"enable_process_collector" default:"false"`
}

MetricsConfig holds configuration for service metrics. swagger:model +kubebuilder:object:generate=true

func (*MetricsConfig) DeepCopy

func (in *MetricsConfig) DeepCopy() *MetricsConfig

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new MetricsConfig.

func (*MetricsConfig) DeepCopyInto

func (in *MetricsConfig) DeepCopyInto(out *MetricsConfig)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.
