thanks to the relentless support by @bdraco, I can post the solution to original request for instructions to install py-spy on HAOS (you need to run it on the host):
2 ways to install and run the required files:
1 The easiest way to run docker commands required for the py-spy is to install the ssh & web terminal addon and disable protection mode then you can ( get into the host and) access the docker cli and follow the rest of the steps described below.
Important: this is the ssh addon in the community addons repo, not the ssh addon in the official addons repo. You cannot access the docker cli from the ssh addon in the official addons repo.
2 On the other hand, you won’t be able to c&p commands (and results) from those terminal windows.
thats the main reason I run ssh in external terminal: to be able to c&p results
For that use the Debugging the Home Assistant Operating System | Home Assistant Developer Docs
method to create authorized keys and copy that to your instance via
ha os import on an attached usb
So you can shell into the Host, which is required for these readings.
ssh [email protected] -p 22222
After having settled the above, you can now continue with the actual setup process of the py-spy files:
docker exec -it homeassistant /bin/bash
next, download and install the correct image for py-spy for your hardware:
For the RPI4:
wget https://github.com/benfred/py-spy/releases/download/v0.3.12/py_spy-0.3.12-py2.py3-none-manylinux_2_17_armv7l.manylinux2014_armv7l.whl
unzip py_spy-0.3.12-py2.py3-none-manylinux_2_17_armv7l.manylinux2014_armv7l.whl
For the intel based use:
https://github.com/benfred/py-spy/releases/download/v0.3.12/py_spy-0.3.12-py2.py3-none-manylinux_2_5_x86_64.manylinux1_x86_64.whl
instead.
There should be a py-spy binary once you call unzip in one of the directories it creates
top (to get pid for homeassistant)
go to the created dir in your /config folder using
cd py_spy-0.3.12.data
cd scripts
Run the next commands for the actual py-spy readings to be analyzed by dev’s:
./py-spy top --pid 60
./py-spy record --pid 60 --duration 120 --rate 100
./py-spy record --pid 60 --duration 300 --rate 200
./py-spy dump --pid 60
Thanks Nick!
