Visualize Erlang/Elixir Nodes On The Command Line base on recon. Document in detail.

• Provide a high-performance tool usable both in development and production settings.
• Focus on important and detailed information about real-time running system.
• Keep minimal consumption.

# mix.exs

   end

%% rebar3 project
rebar3 shell
1> observer_cli:start().
%% mix project
iex -S mix
iex(1)> :observer_cli.start

%% rebar3 project
rebar3 shell --name '[email protected]'
1> observer_cli:start('target@host', 'magic_cookie').
%% mix project
iex --name "[email protected]" -S mix
iex(1)> :observer_cli.start(:'target@host', :'magic_cookie')

❗ ensure observer_cli application been loaded on target node.

1. cd path/to/observer_cli/
2. rebar3 escriptize to generate an escript executable containing the project's and its dependencies' BEAM files. Place script(_build/default/bin/observer_cli) anywhere in your path and use observer_cli command.
3. observer_cli TARGETNODE [TARGETCOOKIE] to monitor remote node.
