Unable to connect remote ejabberd server

[itty-nikhil-ps]

erl -sname `monitor@localhost`
observer_cli:start('ejabberd@nikhil5', 'actualcookiedata').

On the remote machine, the ejabberd server is running with node name ejabberd@nikhil5. On the same remote machine while running above command, the process monitor tool gives the following error-

badrpc,{'EXIT',{undef,[{observer_cli,start,[1500],[]},
                    {rpc,'-handle_call_call/6-fun-0-',5,
                         [{file,"rpc.erl"},{line,197}]}]}}}

Any suggestions/ideas why this is happening? Machine runs CentOS, and ejabberd-18.01, if that information is useful.

:exclamation: ensure observer_cli application been loaded on target node.

you should use escript way.

Escriptize

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 REFRESHMS] to monitor remote node.

this will copy observer_cli/recon's beam to ejabberd node.
