Troubleshooting

  • Check if TCP port 27106 is available. The port may be custom.

    netstat command output

    $ netstat -lntp | grep mongod
tcp        0      0 0.0.0.0:27106            0.0.0.0:*               LISTEN      5655/mongod

    ss command output

    $ ss -ltn | egrep '27016'
LISTEN     0      128          *:27016                     *:*

    lsof command output

    $ lsof -P -n -i :27016 | grep LISTEN
mongod   5655 wfuser    6u  IPv4 39040      0t0  TCP *:27016 (LISTEN)

  • Check the default main log files:

    • <INSTALL_DIR>/supervisord/log/mongodb_db.out.log
    • <INSTALL_DIR>/supervisord/log/mongodb_db.err.log
    • <INSTALL_DIR>/mongodb_db/log/mongodb.log
    $ tail -f <INSTALL_DIR>/supervisord/log/mongodb_db.err.log <INSTALL_DIR>/supervisord/log/mongodb_db.out.log

  • Use the Wfmanager util to check the mongodb out log.

    wfmanager tail mongodb_db

  • Enable debug information.

    Add the appropriate log level to <INSTALL_DIR>/mongodb_db/etc/mongodb.conf (default is 0) using the verbosity option and restart the mongodb_db service:

    ${install_dir}/mongodb_db/etc/mongodb.conf

    systemLog:
   destination: file
   path: /opt/workfusion/mongodb_db/log/mongodb.log
   logAppend: true
   verbosity: 4

  • The verbosity level can range from 0 to 5:

    • 0 is the MongoDB’s default log verbosity level to include Informational messages.

    • 1 to 5 increases the verbosity level to include debug messages.

    wfmanager restart mongodb_db
