Datadog-Azure function

The Datadog-Azure function is used to forward Azure logs to Datadog, including Activity and Diagnostic logs from EventHub.

Quick Start

The provided Node.js script must be deployed into your Azure Functions service. Follow the tutorial below to learn how to do so:

1. Create a new EventHub triggered function

  • Expand your function application and click the + button next to Functions. If this is the first function in your function application, select Custom function. This displays the complete set of function templates.
  • In the search field type Event Hub and choose Event Hub Trigger.
  • Select the Javascript language in the right menu.
  • Enter a name for the function.
  • Add the wanted Event Hub connection or create a new one if you haven't have one already.
  • Select the Event Hub consumer group and the Event Hub Name you want to pull logs from.

2. Provide the code

  • Copy paste the code of the Datadog-Azure function.
  • In the Integrate part:
    • Event Hub Cardinality must be set to Many.
    • Set the Event Parameter Name to eventHubMessages.

3. (optional) Send logs to EU or to a proxy

Send logs to EU

Set the environment variable DD_SITE to datadoghq.eu and logs are automatically forwarded to your EU platform.

Parameters

  • API KEY:

There are 2 possibilities to set your Datadog's API key:

  1. Replace <DATADOG_API_KEY> in the code with your API Key value.
  2. Set the value through the DD_API_KEY environment variable
  • Custom Tags:

You have two options to add custom tags to your logs:

  • Manually by editing the function code: Replace the <TAG_KEY>:<TAG_VALUE> placeholder for the DD_TAGS variable by a comma separated list of tags
  • Automatically with the DD_TAGS environment variable

Learn more about Datadog tagging in our main Tagging documentation.
