Troubleshooting

  • Check if TCP ports 15672 and 45672 are available.

    netstat command output

    $ netstat -tnlp | egrep '15672|45672'
tcp        0      0 127.0.0.1:15672         0.0.0.0:*               LISTEN      20281/beam.smp      
tcp        0      0 0.0.0.0:45672           0.0.0.0:*               LISTEN      26343/nginx: master

    ss command output

    $ ss -ltn | egrep '15672|45672'
LISTEN     0      128    127.0.0.1:15672                    *:*                  
LISTEN     0      511          *:45672                    *:*

    lsof command output

    $ lsof -P -n -i :15672 -i :45672 | grep LISTEN
beam.smp 20281 wfuser   53u  IPv4 74881022      0t0  TCP 127.0.0.1:15672 (LISTEN)
nginx    26343 wfuser    5u  IPv4 74901596      0t0  TCP *:45672 (LISTEN)
nginx    29644 wfuser    5u  IPv4 74901596      0t0  TCP *:45672 (LISTEN)
nginx    29645 wfuser    5u  IPv4 74901596      0t0  TCP *:45672 (LISTEN)

  • Check the default main log files:

    • Access logs: ${install_dir}/supervisord/log/rabbitmq.out.log
    • Error logs: ${install_dir}/supervisord/log/rabbitmq.err.log
    $ tail -f ${install_dir}/supervisord/log/rabbitmq.err.log ${install_dir}/supervisord/log/rabbitmq.out.log

  • Check rabbitmq out (access) log using the Wfmanager util.

    wfmanager tail rabbitmq

  • Enable more detailed debug information.

    Set the debug log level to ${install_dir}/rabbitmq/etc/rabbitmq/rabbitmq.config and restart the mesos-master service:

    ${install_dir}/rabbitmq/etc/rabbitmq/rabbitmq.config:

    [
   {rabbit, [{log_levels,[{connection, debug}]}]}
]

    wfmanager restart rabbitmq
