Core content from the show running resource-monitor command on a VM series firewall

The show running resource-monitor outputs the load rate for each core in the cpu usage part.
It is evenly distributed in each core, so there is a case where there is no load factor, but only one output.
At this time, I would like to know if the output to only one is really the load rate generated from that core or the load rate generated from all cores combined into one and output.
And I would like to know if the output of only one is due to the equipment structure.

On a regular dataplane it could be possible that one core is high while other cores are low if for example a single flow requires a lot of processing (high pps, encapsulation, ...)

Flows in the dataplane are assigned to a core for processing, so a single session will use a single core during it's lifetime

In the screenshot above, however, core 1 is used by the management plane
