A command-line and terminal UI tool for visualizing and diagnosing live Erlang/Elixir (BEAM) nodes, showing VM health, memory, IO, and process rankings. It supports bounded command diagnostics with text, Erlang-term, or JSON output plus an interactive TUI over Erlang distribution.
Use cases
- inspect memory usage of a live Elixir node
- debug high CPU processes in production Erlang
- monitor BEAM VM health from the terminal
- dump process rankings as JSON for automation
- profile a Phoenix application at runtime
- troubleshoot Erlang node performance remotely
When to choose
- you run Erlang/Elixir systems on OTP 26-29 and need production diagnostics
- you want scriptable JSON output for monitoring or AI agents
- you prefer a terminal tool over GUI observer
When to avoid
- you need to inspect non-BEAM runtimes like JVM or Node.js
- your nodes run unsupported OTP versions
- you cannot connect over a trusted network since distribution cookies are not read-only credentials
