osquery is an operating system instrumentation framework for Windows, OS X (macOS), and Linux. The tools make low-level operating system analytics and monitoring both performant and intuitive.

osquery exposes an operating system as a high-performance relational database. This allows you to write SQL queries to explore operating system data. With osquery, SQL tables represent abstract concepts such as running processes, loaded kernel modules, open network connections, browser plugins, hardware events or file hashes.
