Stream logs to Elasticsearch

DataStream 2 supports sending JSON log files to Elasticsearch for improved log analytics.

Depending on your choice, DataStream 2 can upload either uncompressed or gzip-compressed log files.

The custom header feature allows you to enter the name and value for the header that you want to use in Elasticsearch for authorization and tagging. See the API conventions in the Elasticsearch documentation for details.

Before you begin

Before configuring your stream to send logs to this destination, make sure you create and configure an Elasticsearch data cluster with at least one index. See Set up Elasticsearch in the Elasticsearch documentation.

How to

  1. In Display name, enter a human-readable name description for the destination.

  2. In Endpoint, enter an Elasticsearch bulk endpoint URL you want to send your logs to. The endpoint URL should follow the https://<elastic-cloud.com>/_bulk/ format. See Connect to Elasticsearch if you want to retrieve your Elasticsearch endpoint URL.

  3. In Index name, enter the name of the index inside your Elasticsearch cluster where you want to send logs.

  4. In Username, enter your Elasticsearch username you pass in the Authorization header of your requests that grants access to the space protected by basic access authentication.

  5. In Password, enter your Elasticsearch password you pass in the Authorization header of your requests that grants access to the space protected by basic access authentication.

  6. If you want to send compressed gzip files to Elasticsearch, check the Send compressed data box.

  7. Click Validate & Save to validate the connection to the destination and save the details you provided.

Additional options

  1. Optionally, go to Custom header and enter the Custom header name and Custom header value. The custom header name can contain the alphanumeric, dash, and underscore characters.

  2. Optionally, change the Push frequency to receive bundled logs to your destination every 30, 60 or 90 seconds.

  3. Click Validate & Save to validate the connection to the destination and save the details you provided.

Akamaized hostname as endpoint

This destination supports using Akamaized hostnames as endpoints to send DataStream 2 logs for improved security. When you create a property with an Elasticsearch endpoint URL as hostname, this property acts as a proxy between the destination and DataStream. As a result, you can filter incoming traffic to your destination endpoint by IP addresses using the Origin IP Access List behavior. That means only IP addresses that belong to your Akamaized property hostname can send logs to your custom destination. Using Akamaized hostnames as endpoints also requires enabling the Allow POST behavior in your property.

Once the property hostname works as a destination endpoint, you cannot monitor it as a property in this or another stream. If you already monitor a property in DataStream, you cannot use it as a destination endpoint.

To enable this feature:

  1. Go to Property Manager and create a new property. We recommend choosing API Acceleration as the product. See Create a brand new property.

  2. Set your Elasticsearch endpoint URL as the property hostname. See Redirect users to edge servers.

  3. Go to > CDN > Properties or just enter Properties in the search box.

    The Property Groups page opens.

  4. Click the Property Name link to go to the property you created.

  5. Activate the property on the production network. Only properties active on the production network can serve as DataStream destinations. See Activate property on production.

  6. On the Property Details page, click the Version of your configuration that you want to access in Manage Versions and Activations.

    The Property Manager Editor appears.

  7. In the default rule, click Add Behavior, and select Origin IP Access List. Click Insert Behavior.

    The Origin IP Access List behavior appears in the default rule.

  8. Set the Enable slider in the Origin IP Access Control List behavior to On. Click Save.

  9. Click Add behavior, and select Allow POST.

  10. Click Insert Behavior.

    The Allow POST behavior appears in the default rule.

  11. Set the Behavior option in the Allow POST behavior to Allow.

  12. Click Save.

Tip

You may need to additionally configure your property to ensure uninterrupted data flow. See Configuration best practices in the Property Manager guide for other behaviors you can configure in your property.

  1. Configure the firewall settings at your destination endpoint to allow access for IP addresses that belong to CIDR blocks for your Akamaized hostname. See the Origin IP Access List behavior for the list of IP addresses to put on the allow list.

After successfully configuring an Akamaized hostname as the destination endpoint, avoid editing an active property’s setup in Property Manager to ensure uninterrupted data flow. Adding, deleting, and editing hostnames and behaviors may cause unexpected behavior in the DataStream application.

We recommend setting up alerts that send e-mail notifications every time DataStream logs cannot be uploaded to your destination, so you can immediately troubleshoot issues with your property or destination configuration. See Set up alerts.
