QRadar event data is stored in the Ariel database on the Event Processor and any attached Data Nodes. The Event Processor is responsible for processing incoming events, performing correlation, and storing the event data. The attached Data Nodes provide additional storage capacity and can be used to extend the storage available to the Event Processor.

Reference IBM QRadar SIEM V7.5 Administration documentation.

To optimize event and flow payload searches for log data stored for up to a month, an administrator should configure the retention period for payload indexes. Here's the process:

Retention Period Configuration: Set the retention period for payload indexes to match the desired data storage duration (e.g., one month).

Improved Search Efficiency: By configuring the retention period appropriately, QRadar ensures that the indexed data is efficiently searchable, improving performance during searches.

Index Management: Regularly manage and clean up indexes to maintain optimal system performance and storage utilization.

Reference The IBM QRadar SIEM administration guides provide instructions on configuring retention periods for various types of indexes, including payload indexes, to optimize search performance.

When IBM QRadar SIEM V7.5 reaches the events per second (EPS) or flows per minute (FPM) shared license pool limits, the following occurs:

Burst Handling Queue: QRadar utilizes a temporary burst handling queue to manage the overflow of events and flows. This queue temporarily holds data until the system can process it.

Continued Processing: QRadar continues to process events and flows despite reaching the license limits, ensuring no data is lost.

Efficiency: This mechanism allows QRadar to handle short-term spikes in data volume without compromising the integrity or continuity of event and flow processing.

Reference The handling of EPS and FPM limits is described in IBM QRadar SIEM's system administration and configuration guides, which explain how QRadar manages data when license thresholds are exceeded.

Administrators can configure a rule response in QRadar to add event data to a reference set by using the 'add to reference set' rule response. This is a predefined response action in QRadar that allows specific event data to be added to a reference set when the rule conditions are met.

Navigate to the 'Offenses' tab in the QRadar console.

Select 'Rules' from the navigation pane.

Create a new rule or edit an existing rule.

In the 'Rule Response' section, add a new response.

Select the 'Add to Reference Set' response.

Specify the reference set and the data to be added.

Save and deploy the rule.

The primary method used by IBM QRadar to install and manage applications created using the GUI Application Framework Software Development Kit (SDK) is through the REST API interface:

API Endpoint: /api/gui_app_framework

Functionality: This endpoint allows administrators to manage the lifecycle of applications, including installation, updates, and removal.

Integration: Provides seamless integration with the GUI Application Framework, enabling the development and deployment of custom applications within QRadar.

Reference The IBM QRadar API documentation provides details on the /api/gui_app_framework endpoint and its usage for managing GUI applications.
