zephyr.
thread_analyze

"
thread_name
-20s: STACK: unusedavailable_stack_space
usagestack_space_used
/stack_size
(percent_stack_space_used
%); CPU:cpu_utilization
%"- CPU utilization is only printed if runtime statistics are configured via the ``CONFIG_THREAD_RUNTIME_STATS`` kconfig
This function can only be accessed if
CONFIG_THREAD_ANALYZER
is configured for the port inzephyr/prj.conf
. For more infomation, see documentation for Zephyr thread analyzer.

shell_exec
(cmd_in)¶ Executes the given command on an UART backend. This function can only be accessed if
