Profiler for Home Assistant (built-in integration)

About

Profiler is a built-in Home Assistant integration for diagnosing performance and memory use. It adds actions that write diagnostic information to the log, such as current asyncio tasks, thread frames, used sockets, what is scheduled in the event loop, and statistics of LRU caches. It can also create a memory profile or a system profile for a specified number of seconds. For tracking memory, separate actions start and stop logging the growth of objects and the sources of new objects, and another dumps the repr of matching objects to the log. Asyncio debug mode can be switched on or off with an action, and the integration is set up in the UI.
