An InhibitRule specifies that a class of (source) alerts should inhibit notifications for another class of (target) alerts if all specified matching labels are equal between the two alerts. This may be used to inhibit alerts from sending notifications if their meaning is logically a subset of a higher-level alert.
type InhibitRule struct {
// The set of Filters which define the group of source alerts (which inhibit
// the target alerts).
SourceMatchers labels.Matchers
// The set of Filters which define the group of target alerts (which are
// inhibited by the source alerts).
TargetMatchers labels.Matchers
// A set of label names whose label values need to be identical in source and
// target alerts in order for the inhibition to take effect.
Equal map[model.LabelName]struct{}
// contains filtered or unexported fields
}
func NewInhibitRule(cr *config.InhibitRule) *InhibitRule
NewInhibitRule returns a new InhibitRule based on a configuration definition.
An Inhibitor determines whether a given label set is muted based on the currently active alerts and a set of inhibition rules. It implements the Muter interface.
type Inhibitor struct {
// contains filtered or unexported fields
}
func NewInhibitor(ap provider.Alerts, rs []*config.InhibitRule, mk types.Marker, logger log.Logger) *Inhibitor
NewInhibitor returns a new Inhibitor.
func (ih *Inhibitor) Mutes(lset model.LabelSet) bool
Mutes returns true iff the given label set is muted. It implements the Muter interface.
func (ih *Inhibitor) Run()
Run the Inhibitor's background processing.
func (ih *Inhibitor) Stop()
Stop the Inhibitor's background processing.
