Functions

func Instrument

func Instrument(
	method,
	path string,
	action func(*contextmodel.ReqContext) response.Response,
	metrics *API,

Types

type API

type API struct {
	RequestDuration *prometheus.HistogramVec
}

func NewAPIMetrics

func NewAPIMetrics(r prometheus.Registerer) *API

type Alertmanager

type Alertmanager struct {
	Registerer prometheus.Registerer
	*metrics.Alerts
}

func NewAlertmanagerMetrics

func NewAlertmanagerMetrics(r prometheus.Registerer) *Alertmanager

NewAlertmanagerMetrics creates a set of metrics for the Alertmanager of each organization.

type AlertmanagerAggregatedMetrics

type AlertmanagerAggregatedMetrics struct {
	// contains filtered or unexported fields
}

AlertmanagerAggregatedMetrics are metrics collected directly from the registry. Unlike metrics.Alertmanager they are not called within this codebase hence the need for direct collection.

func NewAlertmanagerAggregatedMetrics

func NewAlertmanagerAggregatedMetrics(registries *metrics.TenantRegistries) *AlertmanagerAggregatedMetrics

func (*AlertmanagerAggregatedMetrics) Collect

func (a *AlertmanagerAggregatedMetrics) Collect(out chan<- prometheus.Metric)

func (*AlertmanagerAggregatedMetrics) Describe

func (a *AlertmanagerAggregatedMetrics) Describe(out chan<- *prometheus.Desc)

type Historian

type Historian struct {
	Info              *prometheus.GaugeVec
	TransitionsTotal  *prometheus.CounterVec
	TransitionsFailed *prometheus.CounterVec
	WritesTotal       *prometheus.CounterVec
	WritesFailed      *prometheus.CounterVec
	WriteDuration     *instrument.HistogramCollector
	BytesWritten      prometheus.Counter
}

func NewHistorianMetrics

func NewHistorianMetrics(r prometheus.Registerer) *Historian

type MultiOrgAlertmanager

type MultiOrgAlertmanager struct {
	Registerer prometheus.Registerer

	ActiveConfigurations     prometheus.Gauge
	DiscoveredConfigurations prometheus.Gauge
	// contains filtered or unexported fields
}

func NewMultiOrgAlertmanagerMetrics

func NewMultiOrgAlertmanagerMetrics(r prometheus.Registerer) *MultiOrgAlertmanager

func (*MultiOrgAlertmanager) GetOrCreateOrgRegistry

func (moa *MultiOrgAlertmanager) GetOrCreateOrgRegistry(id int64) prometheus.Registerer

GetOrCreateOrgRegistry gets or creates a *prometheus.Registry for the specified org. It is safe to call concurrently.

func (*MultiOrgAlertmanager) RemoveOrgRegistry

func (moa *MultiOrgAlertmanager) RemoveOrgRegistry(id int64)

RemoveOrgRegistry removes the *prometheus.Registry for the specified org. It is safe to call concurrently.

type NGAlert

type NGAlert struct {
	// Registerer is used by subcomponents which register their own metrics.

	// contains filtered or unexported fields
}

func NewNGAlert

func NewNGAlert(r prometheus.Registerer) *NGAlert

NewNGAlert manages the metrics of all the alerting components.

func ProvideService

func ProvideService() *NGAlert

ProvideService is a Metrics factory.

func ProvideServiceForTest

func ProvideServiceForTest() *NGAlert

ProvideServiceForTest is a Metrics factory used for test.

func (*NGAlert) GetAPIMetrics

func (ng *NGAlert) GetAPIMetrics() *API

func (*NGAlert) GetHistorianMetrics

func (*OrgRegistries) RemoveOrgRegistry

func (m *OrgRegistries) RemoveOrgRegistry(org int64)

RemoveOrgRegistry removes the *prometheus.Registry for the specified org. It is safe to call concurrently.
