When you need to integrate an application or system with Datadog, you have a few choices. The first is using one of our many existing integrations. This will get you access to a wide variety of metrics and events with minimal configuration effort on your part. If your application isn’t one of the integrated applications, then you can opt to create a check using the agent. This requires much more effort and potentially more knowledge on how the application and how Datadog work.
There is another option available if you aren’t using an application that has an integration and you don’t want to create an agent check. You can rely on the application or system sending an email instead. There are two different ways to use Events via Email, depending mostly on whether the application offers you the ability to customize the format of the email body being sent.
In the source plain text email, you only have three fields you can control: sender email address (required), subject (required), and body (optional).
Note that the subject of the email becomes the title of the event and the body of the email becomes the body of the event. Although it looks like a tag appears at the end of the title and body of the event, neither instance are actually tags. The sender of the email also appears at the bottom of the event, so be sure to take advantage of that to help identify the sending application.
In the source JSON-formatted email, you have 10 fields you can control: sender email address, and up to 9 JSON keys. Those keys are title, text, priority, tags, alert type, date happened, host, aggregation key, and source type name.
Note: If your JSON is not properly formatted or if your email is sent with a subject, the event will not appear on your Event Stream.
In a JSON-formatted email, the subject of the email message is irrelevant as it will be replaced by the title in the JSON in the body of the email. All data that appears in the event is defined in the JSON in the body of the email. This JSON must be well-formed or the message will be ignored. This means that not only should it look correct with commas separating key value pairs, it also must be pure JSON. If you are testing the email with a standard email client, the body may be converted to HTML as a convenience to the user. This will cause the JSON to no longer be JSON and the email will be ignored by Datadog.
The allowable JSON keys can be found in the events API documentation.
To set up the email, first log in to your Datadog account at https://app.datadoghq.com. From the Integrations menu, choose APIs, then scroll down to Events API Emails. This section will show you all the emails available for your applications and who created them. Choose the format for your messages from the Format: dropdown, then click Create API Email.
