Вызван получатель с уже уведомленными разрешенными оповещениями
У нас проблема с разрешенными оповещениями, которые отправляются слишком много раз. Мы используем один экземпляр Прометея и один экземпляр менеджера оповещений (без кластера).
Мы ожидаем получить сообщение от диспетчера оповещений с отключенными серверами (оповещения в состоянии активации) и вновь доступными серверами (оповещения в разрешенном состоянии). Что особенно интересно, это когда все серверы снова доступны (группа оповещений в разрешенном состоянии).
Когда сервер или несколько серверов снова становятся доступными, мы получаем несколько вызовов с разными разрешенными оповещениями. Мы должны получить уведомление о разрешенной информации только один раз. У нас есть только одно предупреждение, полученное с помощью сообщения (даже если два оповещения разрешены, см. Последнее действие).

Пожалуйста, обратите внимание, что:
- мы используем пользовательский экспортер, который запускает сценарий для проверки состояния каждого сервера
нам не нужно разрешать тайм-аут повторного интервала, поэтому мы используем большое значение, как предлагается здесь: #935)

Вот как мы воспроизводим эту проблему (обратите внимание, что тег instanceName установлен экспортером).
server01, server02, server03, server04, server05 работают.
Я останавливаю server05:
