Export historical data from QRadar

  • Статия

This article describes how to export your historical data from QRadar. After you complete the steps in this article, you can select a target platform to host the exported data, and then select an ingestion tool to migrate the data.

Diagram illustrating steps involved in export and ingestion.

To export your QRadar data, you use the QRadar REST API to run Ariel Query Language (AQL) queries on data stored in an Ariel database. Because the export process is resource intensive, we recommend that you use small time ranges in your queries, and only migrate the data you need.

Create AQL query

  1. In the QRadar Console, select the Log Activity tab.

  2. Create a new AQL search query or select a saved search query to export the data. Ensure that the query includes the START and STOP functions to set the date and time range.

    Learn how to use AQL and how to save search criteria in AQL.

  3. Copy the AQL query for later use.

  4. Encode the AQL query to the URL encoded format. Paste the query you copied in step 3 into the decoder. Copy the encoded format output.

Execute search query

You can execute the search query using one of these methods.

  • QRadar Console user ID. To use this method, ensure that the console user ID being used for data migration is assigned to a security profile that can access the data you need for the export.
  • API token. To use this method, generate an API token in QRadar.

To execute the search query:

  1. Log in to the system from which you'll download the historical data. Ensure that this system has access to the QRadar Console and QRadar API on TCP/443 via HTTPS.

  2. To execute the search query that retrieves the historical data, open a command prompt and run one of these commands:

    • For the QRadar Console user ID method, run:

      curl -s -X POST -u <enter_qradar_console_user_id> -H 'Version: 12.0' -H 'Accept: application/json' 'https://<enter_qradar_console_ip_or_hostname>/api/ariel/searches?query_expression=<enter_encoded_AQL_from_previous_step>'

    • For the API token method, run:

      curl -s -X POST -H 'SEC: <enter_api_token>' -H 'Version: 12.0' -H 'Accept: application/json' 'https://<enter_qradar_console_ip_or_hostname>/api/ariel/searches?query_expression=<enter_encoded_AQL_from_previous_step>

      The search job execution time may vary, depending on the AQL time range and amount of queried data. We recommended that you run the query in small time ranges, and to query only the data you need for the export.

      The output should return a status, such as COMPLETED, EXECUTE, WAIT, a progress value, and a search_id value. For example:

      Screenshot of the output of the search query command.

  3. Copy the value in the search_id field. You'll use this ID to check the progress and status of the search query execution, and to download the results after the search execution is complete.

  4. To check the status and the progress of the search, run one of these commands:

    • For the QRadar Console user ID method, run:

      curl -s -X POST -u <enter_qradar_console_user_id> -H 'Version: 12.0' -H 'Accept: application/json' 'https:// <enter_qradar_console_ip_or_hostname>/api/ariel/searches/<enter_search_id_from_previous_step>'

    • For the API token method, run:

      curl -s -X POST -H 'SEC: <enter_api_token>' -H 'Version: 12.0' -H 'Accept: application/json' 'https:// <enter_qradar_console_ip_or_hostname>/api/ariel/searches/<enter_search_id_from_previous_step>'

  5. Review the output. If the value in the status field is COMPLETED, continue to the next step. If the status isn't COMPLETED, check the value in the progress field, and after 5-10 minutes, run the command you ran in step 4.

  6. Review the output and ensure that the status is COMPELETED.

  7. Run one of these commands to download the results or returned data from the JSON file to a folder on the current system:

    • For the QRadar Console user ID method, run:

      curl -s -X GET -u <enter_qradar_console_user_id> -H 'Version: 12.0' -H 'Accept: application/json' 'https:// <enter_qradar_console_ip_or_hostname>/api/ariel/searches/<enter_search_id_from_previous_step>/results' > <enter_path_to_file>.json

    • For the API token method, run:

      curl -s -X GET -H 'SEC: <enter_api_token>' -H 'Version: 12.0' -H 'Accept: application/json' 'https:// <enter_qradar_console_ip_or_hostname>/api/ariel/searches/<enter_search_id_from_previous_step>/results' > <enter_path_to_file>.json

  8. To retrieve the data that you need to export, create the AQL query (steps 1-4) and execute the query (steps 1-7) again. Adjust the time range and search queries to get the data you need.
