Functions

func AddMetricsTransportWrapper

func AddMetricsTransportWrapper(server *MetricsServer, app *v1alpha1.Application, config *rest.Config) *rest.Config

AddMetricsTransportWrapper adds a transport wrapper which increments 'argocd_app_k8s_request_total' counter on each kubernetes request

func NewAppCollector

func NewAppCollector(appLister applister.ApplicationLister, appFilter func(obj interface{}) bool) prometheus.Collector

NewAppCollector returns a prometheus collector for application metrics

func NewAppRegistry

func NewAppRegistry(appLister applister.ApplicationLister, appFilter func(obj interface{}) bool) *prometheus.Registry

NewAppRegistry creates a new prometheus registry that collects applications
