# LogsView Demo
This demo shows how to use the `LogsView` component to display logs from a process or a thread in real-time.
Click on any button to launch a process or a thread and see the logs displayed in real-time.
In the thread example, logs are generated randomly with different log levels.
In the process example, logs are generated by a Python script but any command can be executed.

## How to run in a thread?
With `LogsView.run_thread`, you can run a function in a separate thread and capture logs in real-time.
You can configure which logs to capture (log level and logger name).
```py
from gradio_logsview import LogsView
def fn_thread():
# Run `my_function` in a separate thread
# All logs above `INFO` level will be captured and displayed in real-time.
yield from LogsView.run_thread(my_function, log_level=logging.INFO, arg1="value1")
with gr.Blocks() as demo:
logs = LogsView()
btn = gr.Button("Run thread")
btn.click(fn_thread, outputs=logs)
```
## How to run in a process?
With `LogsView.run_process`, you can run a command in a separate process and capture logs from the process in real-time.
```py
from gradio_logsview import LogsView
def fn_process():
# Run a process and capture all logs from the process
yield from LogsView.run_process(
cmd=[mergekit-yaml", "config.yaml", "merge", "--copy-", "--cuda", "--low-cpu-memory"]
)
with gr.Blocks() as demo:
logs = LogsView()
btn = gr.Button("Run process")
btn.click(fn_process, outputs=logs)
```
