Here is a small demo that shows the use of gh_utils.cpu_usage_xxxxxx() set of functions:
– gh_utils.cpu_usage_init()
– gh_utils.cpu_usage_get_core_count()
– gh_utils.cpu_usage_update()
– gh_utils.cpu_usage_get_core_usage()
– gh_utils.cpu_usage_cleanup()
These functions work only on Windows and are available in Lua and Python. Here is how to use them in the different types of scripts to get the overall CPU usage:
INIT script (Lua):
cpu_usage_initialized = gh_utils.cpu_usage_init() overall_cpu_usage = 0 |
TERMINATE script (Lua):
gh_utils.cpu_usage_cleanup() |
FRAME script (Lua):
if (cpu_usage_initialized == 1) then gh_utils.cpu_usage_update() cpu_num_cores = gh_utils.cpu_usage_get_core_count() overall_cpu_usage = 0 for i=0, cpu_num_cores-1 do usage = gh_utils.cpu_usage_get_core_usage(i) overall_cpu_usage = overall_cpu_usage + usage end overall_cpu_usage = overall_cpu_usage / cpu_num_cores end |
The demo displays the overall CPU usage as well as the usage of each CPU core. The CPU usage is updated every second. The demo is available in the full code sample pack in the gl-32/cpu_usage_win32_64/ folder. Launch GeeXLab 0.17+ and drag/drop the demo into GeeXLab.
The demo shows also how to use ImGui functions to display the CPU usage graph (histogram). ImGui is really cool…
