Description

The hawq state utility displays information about a running HAWQ instance. A HAWQ system is comprised of multiple PostgreSQL database instances (segments) spanning multiple machines, and the hawq state utility can provide additional status information, such as:

  • Total segment count.
  • Which segments are down.
  • Master and segment configuration information (hosts, data directories, etc.).
  • The ports used by the system.
  • Whether a standby master is present, and if it is active.
  • Whether Ranger authorization is enabled for HAWQ, and if so, the status of the HAWQ Ranger Plug-in Service.

Options

-b (brief status)
Display a brief summary of the state of the HAWQ system. This is the default mode.

-l, --logdir <logfile_directory>
Specifies the directory to check for logfiles. The default is $GPHOME/hawqAdminLogs.

Log files within the directory are named according to the command being invoked, for example: hawq_config_<log_id>.log, hawq_state_<log_id>.log, etc.

-q, --quiet
Run in quiet mode. Except for warning messages, command output is not displayed on the screen. However, this information is still written to the log file.

-v, --verbose
Displays error messages and outputs detailed status and progress information.

-h, --help (help)
Displays the online help.
