Common errors

error AttributeError: module 'loopmon' has no attribute 'EventLoopMonitor' ↓

cause Incorrect import (e.g., `from loopmon.monitor import EventLoopMonitor`).

fix

Use from loopmon import EventLoopMonitor.

error RuntimeError: Monitor is not running ↓

cause Calling get_stats() before entering the context manager.

fix

Ensure get_stats() is called inside the async with monitor: block.

Warnings

gotcha Monitor must be used as async context manager; otherwise, it won't start monitoring. ↓

fix Use `async with monitor:` block.

gotcha get_stats() returns None if called outside the context manager block. ↓

fix Call get_stats() inside the `async with` block.

Imports

        await asyncio.sleep(1)
    print(monitor.get_stats())

asyncio.run(main())
