openGauss学习笔记-292 openGauss AI特性-AI4DB数据库自治运维-DBMind的AI子功能-X-Tuner：参数调优与诊断-获取帮助

292.1 获取帮助命令

启动调优程序之前，可以通过如下命令获取帮助信息：

gs_dbmind component xtuner --help

292.2 获取帮助输出信息

输出帮助信息结果如下：

usage:  [-h] [--database DATABASE] [--db-user DB_USER] [--db-port DB_PORT] [--db-host DB_HOST] [--host-user HOST_USER] [--host-ssh-port HOST_SSH_PORT] [-f DB_CONFIG_FILE] [-x TUNER_CONFIG_FILE] [-v]
        {train,tune,recommend}

X-Tuner: a self-tuning tool integrated by openGauss.

positional arguments:
  {train,tune,recommend}
                        Train a reinforcement learning model or tune database by model. And also can recommend best_knobs according to your workload.

optional arguments:
  -h, --help            show this help message and exit
  -f DB_CONFIG_FILE, --db-config-file DB_CONFIG_FILE
                        You can pass a path of configuration file otherwise you should enter database information by command arguments manually. Please see the template file share/server.json.template.
  -x TUNER_CONFIG_FILE, --tuner-config-file TUNER_CONFIG_FILE
                        This is the path of the core configuration file of the X-Tuner. You can specify the path of the new configuration file. The default path is /path/to/config/file. You can modify the configuration file to control the tuning process.
  -v, --version         show program's version number and exit

  --db-port DB_PORT, --port DB_PORT
                        Use this port to connect with the database.
  --db-host DB_HOST, --host DB_HOST
                        The IP address of your database InstallationGuide host.
  --host-user HOST_USER
                        The login user of your database InstallationGuide host.
  --host-ssh-port HOST_SSH_PORT
