Dashboard > Multi-Core Monitor

NOTE: For increased convenience and accessibility, the Multi-Core Monitor also can be accessed either from the Dashboard > Multi-Core Monitor, Dashboard > Real-Time Monitor, or System > Diagnostics page. The Multi-Core Monitor display on the System > Diagnostics page is identical to that of the Dashboard > Multi-Core Monitor. Both monitors display information about single cores. The Dashboard > Real-Time Monitor shows the information either for combined data in flow chart format or for individual cores in bar chart format.

The Multi-Core Monitor displays dynamically updated statistics on utilization of the 18 to 32 individual cores of the Dell SonicWALL network security appliance. The number of cores depends on the model of the appliance.

Core 1 through Core 8 handle the control plane, and its usage is displayed in green on the Multi-Core Monitor. The remaining cores handle the data plane. To maximize processor flexibility, functions are not dedicated to specific cores; instead all cores can process all data plane tasks. Memory is shared across all cores. Each core can process a separate flow simultaneously, allowing for up to 88 flows to be processed in parallel.

NOTE: High utilization on Core 1 is normal while browsing the Web management interface and applying changes. All Web management requests are processed by Core 1 through core 8 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.
