RabbitMQ cluster status: how to parse Erlang's beam from a shell?

I need to monitor rabbitmq cluster status.

REST API doesn't provide information about partitions. So I need to use app rabbitmqctl:

# rabbitmqctl cluster_status
Cluster status of node 'rabbit@rabbit-1' ...
[{nodes,[{disc,['rabbit@rabbit-1','rabbit@rabbit-2',
                'rabbit@rabbit-3']}]},
 {running_nodes,['rabbit@rabbit-3','rabbit@rabbit-2',
                 'rabbit@rabbit-1']},
 {cluster_name,<<"rabbit@rabbit-1">>},
 {partitions,[]},
 {alarms,[{'rabbit@rabbit-3',[]},
          {'rabbit@rabbit-2',[nodedown]},
          {'rabbit@rabbit-1',[]}]}]

I need to check {partitions,[]},. If there is empty [] it is ok. Otherwise I have problem.

I found example of use erlang from bash:

erl -eval 'erlang:display(erlang:system_info(otp_release)), halt().'  -noshell

Is possible to parse rabbitmqctl stdout using erl (or other tool) and return info "empty / not empty" or return code?

I absolutely don't know Erlang.

If anyone help me, I will be happy :-)

you can use this API

http://your_ip:15672/api/nodes

where you can check if a node is up or down 

name: "rabbit@t-srv-rabbit-cent04",
type: "disc",
running: false,
+cluster_links: (0)[...],

or partitions

},
-{
-partitions: (0)[
],
os_pid: "8070",
fd_total: 300000,
sockets_total: 269908,
mem_limit: 1590196633,

you don't need erlang shell
