Functions ¶
func WithContext ¶
func WithContext(ctx context.Context, m AlertMarker) context.Context
WithContext returns a copy of ctx carrying the given AlertMarker. Inhibitor and Silencer extract it from the context to write per-group alert status.
Types ¶
type AlertMarker ¶
type AlertMarker interface {
// SetInhibited sets the inhibitedBy for the given fingerprint.
// If inhibitedBy is empty, it clears the inhibitedBy.
SetInhibited(fingerprint model.Fingerprint, inhibitedBy []string)
// SetSilenced sets the silencedBy for the given fingerprint.
// If silencedBy is empty, it clears the silencedBy.
SetSilenced(fingerprint model.Fingerprint, silencedBy []string)
// Status returns the AlertStatus for the given fingerprint.
// If the fingerprint is not found, it returns an unknown status.
Status(fingerprint model.Fingerprint) alert.AlertStatus
// Delete removes markers for the given fingerprints.
Delete(fingerprints ...model.Fingerprint)
}
AlertMarker tracks per-alert silenced/inhibited status within a single aggregation group. Each aggregation group owns its own instance. All methods are goroutine-safe.
func FromContext ¶
func FromContext(ctx context.Context) (AlertMarker, bool)
FromContext extracts the AlertMarker from ctx. If no marker is present, it returns (nil, false).
func NewAlertMarker ¶
func NewAlertMarker() AlertMarker
NewAlertMarker returns a new AlertMarker backed by an in-memory map.
type GroupMarker ¶
type GroupMarker interface {
// Muted returns true if the group is muted, otherwise false. If the group
// is muted then it also returns the names of the time intervals that muted
// it.
Muted(routeID, groupKey string) ([]string, bool)
// SetMuted marks the group as muted, and sets the names of the time
// intervals that mute it. If the list of names is nil or the empty slice
// then the muted marker is removed.
SetMuted(routeID, groupKey string, timeIntervalNames []string)
// DeleteByGroupKey removes all markers for the GroupKey.
DeleteByGroupKey(routeID, groupKey string)
}
GroupMarker helps to mark groups as active or muted. All methods are goroutine-safe.
TODO(grobinson): routeID is used in Muted and SetMuted because groupKey is not unique (see #3817). Once groupKey uniqueness is fixed routeID can be removed from the GroupMarker interface.
func NewGroupMarker ¶
func NewGroupMarker() GroupMarker
NewGroupMarker returns an instance of a GroupMarker implementation.
