Current I use OpsGenie with Prometheus and I have a big problem. Alertmanager creates new alert and after a while it closes this alert during this operation opsgenie always creates new alerts, not de-duplicate existing alert. The reason why this happens is because OpsGenie not solving the alarms but closing them. In summary, I have a very large number of the same alerts that should be duplicated.
In web app it it impossible to select a status other than closed.
