High disk usage or disk is full?
QRadar requires that certain partitions require disk space and this page is intended to outline troubleshooting administrators can take to review for disk space issues. 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.
