The sfcbd (Small foot print CIM broker daemon) is responsible for reporting the hardware status that is viewed via the vSphere client.

In order to enable debug logging:

  1. Stop sfcbd service by running the command:
    /etc/init.d/sfcbd-watchdog stop
  2. Set the CIM log level to 7 by running the command:
    esxcfg-advcfg -s 7 /UserVars/CIMLogLevel
  3. Start sfcbd service by running the command:
    /etc/init.d/sfcbd-watchdog start
  4. Collect the vmsupport log bundle. In ESXi 5.1 and above, sfcbd logs to /var/log/syslog.log.
    **Note: **The default logging level is 3. Ensure you revert the logging level back to 3 after collecting the debug logs.

In order to revert the debug logging back to 3:

  1. Stop sfcbd service
  2. Set the CIM log level back to 3:
    `esxcfg-advcfg -s 3 /UserVars/CIMLogLevel
  3. Start sfcbd
    `/etc/init.d/sfcbd-watchdog start
