Display a rolling graph of Task CPU usage inside an ESP32
- any Arduino program with wifi, just include the taskman.h, call taskman_setup() in the setup(), and it will serve a graph at port 81 of your ip as below with 100 seconds of 1 second averages of all the tasks above 2% utilization on your esp32
- with 2 cores on the esp32-s (on the ai thinker esp32-cam), the percentages will add to 200%
https://www.reddit.com/r/esp32/comments/1oeq3v6/whats_happening_inside_my_esp32/
- download the .ino and the .h
- edit your ssid and password into the .ino file
- install on esp32
- goto your ip address with port 81, like 192.168.1.111:81
- then add your own code, and delete the lines that produce the fake load on core 0, core 1, and inside the loop
Good stuff not added yet
- killing tasks
- changing priorities
The endpoints are below - the esp32 keeps track of 100 points, and will deliver that entire series for every task that every exceeded 2% of its core, or for the current data you can just get the last second snapshot of every 2% plus task. The data collector only runs once per second, so 2 fetchs in a second will give you the same data.
