Turning Linux /proc into Domain Queries with TeaQL Rust
Reading system information on Linux is not difficult. Open /proc/meminfo, /proc/[pid]/stat, and /proc/[pid]/task, parse the text, and send the results to a terminal UI.
The harder part is keeping that code maintainable. As process fields grow, filtering becomes more complex, or the same system data needs to serve monitoring agents, alerting jobs, and management APIs, file reads and string parsing scattered through application code quickly become a liability.
Linux System Info using TeaQL demonstrates another approach: model Linux system information as domain objects, let TeaQL generate type-safe Rust query APIs, and use teaql-provider-linux to execute those queries against /proc. The example then builds an interactive process and thread monitor with ratatui.
