VOXL Inspect CPU

voxl-inspect-cpu is a tool to check the CPU/GPU utilization and temperature of the various voxl components. It is part of the voxl-cpu-monitor package and subscribes to the cpu_monitor pipe. If you don’t get data using this tool, make sure the voxl-cpu-monitor systemd service is running using VOXL Inspect Services.

Arguments

voxl2:/$ voxl-inspect-cpu --help

Tool to print cpu monitor information to the screen for inspection

Run this in debug mode to enable debug prints in the libmodal_pipe client code.
You can also try the auto-reconnect mode which is useful for some projects but
not all.

-f, --full         print full table with more data
-j, --json         output results as JSON instead of a table
-k, --json_human   print output in human-readable formatted json format
                       for development and debug only
-t, --test         get a single sample
-h, --help         print this help message

The -f/--full option adds Top CPU Consumers and Top Memory Consumers process tables to the output. The -t/--test option prints a single sample and exits.

Use

The left column is a table of per-core frequency, temperature, and utilization followed by the GPU. The right column shows the clock, uptime, memory use, memory allocation rate, and the current flags. The Governor field shows one of Auto, Perf, Powersave, Conserv, or Cool.
