 %description
-
 The Alertmanager handles alerts sent by client applications such as the
 Prometheus server. It takes care of deduplicating, grouping, and routing them to
 the correct receiver integration such as email, PagerDuty, or OpsGenie. It also
 takes care of silencing and inhibition of alerts.
