Types ¶
type Appendable ¶
Appendable returns an Appender.
type Manager ¶
type Manager struct {
// contains filtered or unexported fields
}
Manager maintains a set of scrape pools and manages start/stop cycles when receiving new target groups form the discovery manager.
func NewManager ¶
func NewManager(logger log.Logger, app Appendable) *Manager
NewManager is the Manager constructor
func (*Manager) ApplyConfig ¶
ApplyConfig resets the manager's target providers and job configurations as defined by the new cfg.
func (*Manager) Run ¶
func (m *Manager) Run(tsets <-chan map[string][]*targetgroup.Group) error
Run receives and saves target set updates and triggers the scraping loops reloading. Reloading happens in the background so that it doesn't block receiving targets updates.
func (*Manager) Stop ¶
func (m *Manager) Stop()
Stop cancels all running scrape pools and blocks until all have exited.
func (*Manager) TargetsActive ¶
TargetsActive returns the active targets currently being scraped.
func (*Manager) TargetsAll ¶
TargetsAll returns active and dropped targets grouped by job_name.
func (*Manager) TargetsDropped ¶
TargetsDropped returns the dropped targets during relabelling.
type MetricMetadata ¶
type MetricMetadata struct {
Metric string
Type textparse.MetricType
Help string
Unit string
}
MetricMetadata is a piece of metadata for a metric.
type Target ¶
type Target struct {
// contains filtered or unexported fields
}
Target refers to a singular HTTP or HTTPS endpoint.
func (*Target) DiscoveredLabels ¶
DiscoveredLabels returns a copy of the target's labels before any processing.
func (*Target) Health ¶
func (t *Target) Health() TargetHealth
Health returns the last known health state of the target.
func (*Target) LastScrape ¶
LastScrape returns the time of the last scrape.
func (*Target) LastScrapeDuration ¶
LastScrapeDuration returns how long the last scrape of the target took.
func (*Target) Metadata ¶
func (t *Target) Metadata(metric string) (MetricMetadata, bool)
Metadata returns type and help metadata for the given metric.
func (*Target) MetadataList ¶
func (t *Target) MetadataList() []MetricMetadata
func (*Target) SetDiscoveredLabels ¶
SetDiscoveredLabels sets new DiscoveredLabels
type TargetHealth ¶
type TargetHealth string
TargetHealth describes the health state of a target.
const ( HealthUnknown TargetHealth = "unknown" HealthGood TargetHealth = "up" HealthBad TargetHealth = "down" )
The possible health states of a target based on the last performed scrape.
