Icinga 2

The Icinga 2 Collector subscribes to the Icinga 2 API event streams, generates Tornado Events from the Icinga 2 Events, and publishes them on the Tornado Engine.

On startup, it connects to Icinga 2 Server API and subscribes to user defined Event Streams.

In order to configure the stream, create a JSON file in /neteye/shared/tornado_icinga2_collector/conf/streams/. More than one stream subscription can be defined.

For each stream, you must provide two values in order to successfully create a subscription:

• stream: the stream configuration composed of:

  • types: An array of Icinga 2 Event types;

  • queue: A unique queue name used by Icinga 2 to identify the stream;

  • filter: An optional Event Stream filter. Additional information about the filter can be found in the official documentation.

• collector_config: The transformation logic that converts an Icinga 2 Event into a Tornado Event.

Below you may find examples of valid content for a stream configuration JSON file:

For all Icinga 2 events

{
  "stream": {
    "types": ["CheckResult",
              "StateChange",
              "Notification",
              "AcknowledgementSet",
              "AcknowledgementCleared",
              "CommentAdded",
              "CommentRemoved",
              "DowntimeAdded",
              "DowntimeRemoved",
              "DowntimeStarted",
              "DowntimeTriggered"],
    "queue": "icinga2_AllEvents_all"
  },
  "collector_config": {
    "event_type": "icinga2_AllEvents_all",
    "payload": {
      "response": "${@}"
    }
  }
}

For check result events

{
  "stream": {
    "types": ["CheckResult"],
    "queue": "icinga2_CheckResult_all"
  },
  "collector_config": {
    "event_type": "icinga2_CheckResult_all",
    "payload": {
      "response": "${@}"
    }
  }
}

For notification events

{
  "stream": {
    "types": ["Notification"],
    "queue": "icinga2_Notification_all"
  },
  "collector_config": {
    "event_type": "icinga2_Notification_all",
    "payload": {
      "response": "${@}"
    }
  }
}

For statechange events

{
  "stream": {
    "types": ["StateChange"],
    "queue": "icinga2_StateChange_all"
   },
  "collector_config": {
    "event_type": "icinga2_StateChange_all",
    "payload": {
      "response": "${@}"
    }
  }
}

Note

Based on the Icinga 2 Event Streams documentation, multiple HTTP clients can use the same queue name as long as they use the same event types and filter.

After configuring the streams, restart tornado_icinga2_collector resource.
