Types ¶
type AlertChecker ¶
type AlertChecker struct {
// Lock when accessing monitored. Needed because status runs in a different
// goroutine.
sync.RWMutex
// contains filtered or unexported fields
}
AlertChecker implements the alerthook.AlertHandler interface, it receives alerts and applies this package's business logic to them.
func New ¶
func New(registerer prometheus.Registerer, externalURL string) *AlertChecker
New returns a new AlertChecker. It is only expected there is one instance of this per binary as it runs a goroutine in the background.
func (*AlertChecker) HandleAlert ¶
func (ac *AlertChecker) HandleAlert(ctx context.Context, alert *alertmanager.Alert) error
HandleAlert receives a single alert from the alerts sent to an alertmanager webhook. It parses the annotations as configuration and then sends a "handleAlert" struct to handleChan, which the checker goroutine receives and calls updateInstance.
func (*AlertChecker) Healthy ¶
func (ac *AlertChecker) Healthy() bool
