SonicOS 5.8.1 Administrator Guide
Core Monitor
The Core Monitor displays dynamically updated statistics on the utilization of a single specified
core on the SonicWALL NSA E-Class series security appliances. The View Style provides a
wide range of time intervals that can be displayed to review core usage.
Note High utilization on Core 0 is normal while browsing the Web management interface and
applying changes. All Web management requests are processed by Core 0 and do not
impact the other cores. Traffic handling and other critical, performance-oriented and system
tasks are always prioritized by the scheduler, and will never be impacted by web
management usage.
