IBM Updated C1000-156 Exam Questions and Answers by olly

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.

ReferencesThe 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.

When the error "Insufficient disk space to complete data export request" is encountered, and the Export Directory property in the System Settings has the default configuration, the disk partition that needs to be checked is/store/ariel/events/exports. This directory is typically used for exporting event data in QRadar SIEM. The error indicates that the available disk space in this partition is insufficient to handle the export operation. Administrators should check the storage usage of this partition and manage the space by either cleaning up unnecessary files or expanding the storage capacity.
