Send records from ExtraHop to Google BigQuery

You can configure your ExtraHop system to send transaction-level records to a Google BigQuery server for long-term storage, and then query those records from the ExtraHop system and the ExtraHop REST API. Records on BigQuery recordstores expire after 90 days.

Before you begin

  • You need the BigQuery project ID
  • You need the credential file (JSON) from your BigQuery service account. The service account requires the BigQuery Data Editor, BigQuery Data Viewer, and BigQuery User roles.
  • For access to the ExtraHop Cloud Recordstore, your sensors must be able to access outbound TCP 443 (HTTPS) to these fully qualified domain names:
    • bigquery.googleapis.com
    • oauth2.googleapis.com
    • www.googleapis.com
    • www.mtls.googleapis.com
    • iamcredentials.googleapis.com

    You can also review the public guidance from Google about computing possible IP address ranges for googleapis.com.

  • If you want to configure the BigQuery recordstore settings with Google Cloud workload identity federation authentication, you need the configuration file from your workload identity pool.
    Note:The workload identity provider must be set up to provide a fully valid OIDC ID Token in response to a Client Credentials request. For more information about workload identity federation, see https://cloud.google.com/iam/docs/workload-identity-federation.

Send records from ExtraHop to BigQuery

Complete this procedure on all connected Command and Discover appliances.
Note:Any triggers configured to send records through commitRecord to an Explore appliance are automatically redirected to BigQuery. No further configuration is required.
Important:If your ExtraHop system includes a Command appliance, configure all appliances with the same recordstore settings or transfer management to manage settings from the Command appliance.
  1. Log in to the Administration settings on the ExtraHop system through https://<extrahop-hostname-or-IP-address>/admin.
  2. In the Records section, click Recordstore.
  3. Select Enable BigQuery as the recordstore.
    Important:If you are migrating to BigQuery from a connected Explore appliance, you will no longer be able to access records stored on the Explore appliance.
  4. In the Project ID field, type the ID for your BigQuery project. The project ID can be found in the BigQuery API console.
  5. In the JSON Credential File field, click Choose File and select one of the following files:
    • The credential file saved from your BigQuery service account.

      See the Google Cloud documentation on how to create a service account and generate a service account key.

    Important:Create your service account with the following BigQuery roles:
    • BigQuery Data Editor
    • BigQuery Data Viewer
    • BigQuery User
    • The configuration file from your workload identity pool.
  6. (Optional): If you chose the configuration file from your workload identity pool in the previous step, select Authenticate through local Identity Provider for Workload Identity Federation and enter the credentials from your identity provider in the following fields:
    • Token URL
    • Client ID
    • Client Secret
  7. Click Test Connection to verify that your sensor can communicate with the BigQuery server.
  8. Click Save.
After your configuration is complete, you can query for stored records in the ExtraHop system by clicking Records.
Important:Do not modify or delete the table in BigQuery where the records are stored. Deleting the table deletes all stored records.

Transfer recordstore settings

If you have a Command appliance connected to your ExtraHop sensors, you can configure and manage the recordstore settings on the sensor, or transfer the management of the settings to the Command appliance. Transferring and managing the recordstore settings on the Command appliance enables you to keep the recordstore settings up to date across multiple sensors.

Recordstore settings are configured for connected recordstores and do not apply to the Explore appliance.
  1. Log in to the Administration settings on the sensor through https://<extrahop-hostname-or-IP-address>/admin.
  2. In the Records section, click Recordstore.
  3. From the Recordstore settings drop-down list, select the Command appliance and then click Transfer.
    If you later decide to manage the settings on the sensor, select this Discover appliance from the Recordstore settings drop-down list and then click Transfer.
