MINOR: General go HTTP/REST performance tips:
- use a struct here rather than
map[string]anyto avoid extraneous allocations. - don't make a map to iterate through the headers: just do
req.Header.Set("Content-Type", "application/json") - don't make a new
http.Clientfor each request: they're safe to share between invocations. if you don't care which client to use, usehttp.DefaultClient - either or both of the client or request context should have a timeout.

this function should return an error.

check this error and return it.

again, don't use map[string]any: just make a struct type that's the shape you want. in this case, it would be
type Result struct {
Data struct {
Pod struct {
MachineID string `json:"machineId"`
} `json:"pod"`
} `json:"data"`

use return fmt.Errorf with %w instead of just printing the error.

What will happen if people try to run this on the client? Is there anything telling them that it is a diagnostic to be run specifically through web terminal on the pod? I think somebody will try to run it locally and be confused by the output if not |
Most of the output in json file would be empty though script will try to run PyTorch test. |
Added new command: gpu-test
Curently it's including one of my script to test out PyTorch (PyTorch,go file)
Saves debug informations to /workspace/gpu_diagnostics.json
What script does:
Gather all informations about host including:
Runs test on all attached GPU's to makre sure PyTorch fully utilizes CUDA
Logs error messages into .json file for tech support to review.
