About
This extension was created mainly as practice for me working with Chrome extensions and its API. This extension can be used to monitor multiple system and tab-specific metrics including: CPU model, number of threads, memory capacity, screen resolution, CPU usage, CSS cache, image cache, JavaScript memory, network usage, script cache, and SQLite memory. It can be used during development to quickly monitor these things without having to access Chrome developer tools.
