The Data Feed service sends node data to a 3rd party service. This can be useful when updating configuration management databases, external security dashboards, and IT service management platforms. The following types of information are sent:

• Ohai data gathered from each managed node - This data includes hardware, operating system, and installed program information. Some variation depends on the managed operating system.
• Configuration information about each managed node - This information includes Chef Client Run status, Runlists, Cookbooks, and Recipes running against each node.
• Compliance information about each node that shows the compliance state - This information includes passed and failed controls for each profile executed against that node.

A Data Feed operates by doing the following:

• Every 4 hours, the data-feed-service will aggregate the client runs and compliance reports from the previous 4 hours and send this information to the registered destinations. This time interval is 4 hours by default but is configurable.
• If there are no destinations, the aggregation will not occur.
• The data aggregates and sends in batches of 50 nodes at a time. The batch amount is 50 by default but is configurable.

By default, only Admin users of Chef Automate may create and manage Data Feeds.

Data Feed Integration

Currently, the data feed has two types of integrations:

• Webhook Integration
  • ServiceNow

Enable/Disable a Data Feed Instance

Chef Automate lets you temporarily disable the data feed. It can be helpful if the data feed is going under maintenance or you don’t want to send the node or compliance data to a data feed.

The data feed instances are by default enabled when created. To disable a feed:

• Select Disable from the top left corner of the details page. OR

• Select the ellipses icon from the list of data feeds and select Disable.

To enable a disabled data feed:

• Select Enable from the top left corner of the details page. OR

• Select the ellipses icon from the list of data feeds and select Enable.

Delete a Data Feed Instance

To delete an individual instance:

1. Select the ellipses icon .
2. Select Delete.
3. Select Delete Data Feed to confirm the action.

Configuring Global Data Feed Behavior

To modify Data Feed behavior with the available configuration settings:

• Create a configuration patch file to update the configuration settings. Save this file in the .toml file format and name your file as desired. For example, data-feed-patch.toml
• Include one or more configuration settings and their updated value(s) in your configuration patch .toml file to reflect the desired global Data Feed behavior:
  • Use the feed_interval setting to change the interval for the Data Feed collection. The default value is four hours
  • Use the node_batch_size setting to change the number of sets of node data sent in each batch to your endpoint. The default value is 50 nodes
  • Use the updated_nodes_only setting to determine what data to include in each export. The default setting is true, which causes the aggregation of only the changed data of updated nodes since the last export. Set updated_nodes_only to false, and it aggregates all data of updated nodes since the last export
  • To reduce the IP address range for the collected and processed node data, update the disable_cidr_filter setting to false and update the cidr_filter setting to cover the required IP address range. For example, you may wish to send only production or test node traffic
  • Use the accepted_status_codes setting to define an array of HTTP status codes that the Data Feed Service will treat as success if returned by the 3rd party endpoint. If the status code is not in the accepted_status_codes list, then an error will be logged
• Save your configuration patch file changes before continuing to the next step.
• Apply your configuration changes with the Chef Automate command-line tool:

    chef-automate config patch data-feed-patch.toml

where `data-feed-patch.toml` is this example's configuration patch file.

Configuration Patch File Example

[data_feed_service.v1.sys]
  [data_feed_service.v1.sys.service]
        feed_interval = "4h"
        node_batch_size = 50
        updated_nodes_only = true
        disable_cidr_filter = true
        cidr_filter = "0.0.0.0/0"
        accepted_status_codes = [200, 201, 202, 203, 204]
      [data_feed_service.v1.sys.log]
        level = "info"

To debug any issues with the Data Feed Service in Chef Automate, update the following section in your configuration patch file by changing the log_level value to “debug”:

    [data_feed_service.v1.sys.log]
    log_level = "debug"
