Disk Space 101

QRadar Support Team technical resolutions to common problems with disk space usage, troubleshooting and and known issues articles.

High disk usage or disk is full?

QRadar has two different partition tables based on the QRadar version, 7.2.x vs 7.3.x, that would determine the starting point for the troubleshooting process. By default, the QRadar disk sentry check runs every 60 seconds and looks for high disk usage across the QRadar partitions. If any of these partitions exceed 90% usage, a warning notification is sent to the UI. For the partitions critical to system functionality, if the partition usage grows above 95%, system services will be stopped to avoid the partition becoming completely full and possibly causing further issues.

Partition requirements and recommendations

The partition requirements and recommendations revolve around two main topics that affect the partition sizing; installing QRadar on your own hardware (so called “software install”) and upgrades from 7.2.x to 7.3.x which repartitions the system. For a QRadar installation on a QRadar appliance, the installation script automatically partitions the space and no user input is required.
