Events with a Custom Agent Check

Events with a Custom Agent Check


To submit an event from a custom Agent Check use the event(<EVENT_DICT>) function:

              "timestamp": <TIMESTAMP_EPOCH>,
              "event_type": "<EVENT_NAME>",
              "msg_title": "<TITLE>",
              "msg_text": "<MESSAGE>",
              "aggregation_key": "<AGGREGATION_KEY>",
              "alert_type": "<ALERT_TYPE>",
              "source_type_name": "<SOURCE_TYPE>",
              "host": "<HOSTNAME>",
              "tags": ["<TAGS>"],
              "priority": "<PRIORITY>"

The following keys and data types are available in the event dictionary:

Key Type Required Description
timestamp Integer Yes The epoch timestamp for the event
event_type String Yes The event name
msg_title String Yes The title of the event
msg_text String Yes The text body of the event
aggregation_key String No A key to use for aggregating events
alert_type String No error, warning, success, or info (defaults to info)
source_type_name String No The source type name
host String No The host name
tags List of strings No A list of tags associated with this event.
priority String No Specifies the priority of the event (normal or low).


This is an example of using a custom Agent check to send one event periodically. See Writing a Custom Agent Check for more details.

  1. Create a new directory event_example.d/ in the conf.d/ folder at the root of your Agent’s configuration directory.

  2. In the event_example.d/ folder, create a configuration file named event_example.yaml with the following content:

    instances: [{}]
  3. Up one level from the conf.d/ folder, go to the checks.d/ folder.

  4. In this folder, create a custom check file named with the following content:

        from datadog_checks.base import AgentCheck
        __version__ = "1.0.0"
        class MyClass(AgentCheck):
            def check(self, instance):
                        "timestamp": time.time(),
                        "event_type": "Error",
                        "msg_title": "Example Event",
                        "msg_text": "This is an example event coming from Datadog.",
                        "alert_type": "error",
  5. Restart the Agent.

  6. For validation, run the Agent’s status command and look for event_example under the Checks section:

      Running Checks
        event_example (1.0.0)
          Instance ID: event_example:d884b5186b651429 [OK]
          Total Runs: 2
          Metric Samples: Last Run: 0, Total: 0
          Events: Last Run: 1, Total: 2
          Service Checks: Last Run: 0, Total: 0
          Average Execution Time : 0s
  7. Finally, go to your Datadog Event stream to see your events:
