Functions

func GetSupportedPrometheusCNIMetricsMapping

func GetSupportedPrometheusCNIMetricsMapping() map[string]prometheus.Collector

This can be enhanced to get it programatically. Initial CNI metrics helper enhancement includes only Gauge. Doesn't support GaugeVec, Counter, CounterVec and Summary

func PrometheusRegister

func PrometheusRegister()

func ServeMetrics

func ServeMetrics(metricsPort int)

ServeMetrics sets up ipamd metrics and introspection endpoints

func SetupMetricsServer

func SetupMetricsServer(metricsPort int) *http.Server
