We use Opsgenie heartbeats with the Slack integration. One of our systems went down so a heartbeat failed to reach Opsgenie which resulted in a Slack notification. Our devops operator using Slack closed the alert (prior to the issue being resolved) with the assumption that the heartbeat status would reset and that if the heartbeat still was not received, that a new alert would be generated. A new alert was not generated.
Is this the expected behavior?
Is it possible to configure Opsgenie heartbeats so that closing the alert prematurely would still allow a missing heartbeat to generate a new alert?
