如何从升级通知模板中获取 icinga2 中的单个确认/确定通知？

Question

在 icinga2 监控中，我希望能够在服务已关闭一段时间后升级问题通知，或者在停止营业时间时降级。我想在服务恢复时收到一条通知。

当我将 "service-test-down-1" 和 "service-test-down-2" 设置为所有类型和状态时，当服务正常时我会收到两条 "OK" 消息。当我像下面这样设置它时，将 OK 消息和 Not-OK 消息分开，我从来没有得到任何 OK。我觉得这应该是直截了当的，但我一直没有取得任何进展。

apply Notification "service-test-down-1" to Service {
  command = "dispatch-service"
  states = [ Warning, Critical, Unknown ]
  types = [ Problem, Custom, FlappingStart, FlappingEnd,
            DowntimeStart, DowntimeEnd, DowntimeRemoved ]
  users = ["russ"]
  period = "24x7"
  assign where "tests" in service.groups
  vars.priority = "medium"
  times.begin = 0m
  times.end = 3m
  interval = 1m
}

apply Notification "service-test-down-2" to Service {
  command = "dispatch-service"
  states = [ Warning, Critical, Unknown ]
  types = [ Problem, Custom, FlappingStart, FlappingEnd,
            DowntimeStart, DowntimeEnd, DowntimeRemoved ]
  period = "24x7"
  users = ["russ"]
  assign where "tests" in service.groups
  vars.priority = "medium"
  times.begin = 3m
  times.end = 12h
  interval = 2m
}
apply Notification "service-test-recovery" to Service {
  command = "dispatch-service"
  states = [ OK ]
  types = [ Acknowledgement, Recovery ]
  users = ["russ"]
  period = "24x7"
  vars.priority = "medium"
  assign where "tests" in service.groups
  interval = 1
}

apply Service "NotificationTest" {
  enable_active_checks = true
  check_command = "passive"
  max_check_attempts = 1

  ignore where host.vars.noservices == true
  groups += ["tests"]
  assign where host.name == "icinga2.acceleration.net"
  max_check_attempts = 5
  check_interval = 5m
  retry_interval = 5m
}

此配置由 icinga 打印为：

Answer 1

icinga2 的开发者（在 github：https://github.com/Icinga/icinga2/issues/5478）提供的答案是，当您有通知升级时，无法从 icinga2 内部发送单个恢复通知。

每个升级都是一个单独的通知对象，每个通知问题的通知都将发送一条恢复消息。不会向任何从未发送过 PROBLEM 通知的通知对象发送任何 RECOVERY 通知（这似乎是错误的，但无论如何）。

建议的解决方案是使用通知代理为您删除重复的消息。鉴于不希望有状态代理，我做了一个函数来设置 current_escalation 在通知的主机/服务上，这样只有当前升级才会实际发送 RECOVERY 消息，我们的代理仍然可以是无状态的。 github.
