observer_cli

Tech stack & purpose

observer_cli is a production-ready diagnostics tool for inspecting live Erlang and Elixir systems, built for operators, automation, and AI agents. It provides two interfaces—a command-line interface recommended for bounded, repeatable diagnostics with stable text, Erlang-term, or JSON output, and a terminal user interface for interactive exploration. The tool can diagnose capacity pressure, inspect memory and performance metrics, rank processes and tables, capture function traces, and feed versioned machine-readable responses to automation workflows. It is written in Erlang and Elixir, supports Erlang/OTP versions 26–29, and connects to target nodes via Erlang distribution.
