Troubleshooting

• Check if TCP port 27106 is available. A 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
  

  The Wfmanager util can be used to check 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 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
