gs_check工具帮助用户进行集群运行状态（集群、双机和CM状态）、集群部署巡检项（目录权限、数据库版本、环境变量和参数等）、运行巡检项（连接状态、锁数量、游标数量和连接数量等）、管理数据库对象等选项的检查，以确保数据库处于正常可用状态。
前提条件
- 集群预安装成功。
- 集群安装成功。
- 执行集群间的gs_check检测，需要各主机间互信状态正常。如果不确定互信状态，可以参考gs_sshexkey检查和创建互信。
语法
- 健康检查（安装集群的用户）
gs_check -i ITEM [...] [-U USER] [-L] [-X XMLFILE] [-l LOGFILE] [-o OUTPUTDIR] [--skip-root-items] [--format]
gs_check -e SCENE_NAME [-U USER] [-L] [-X XMLFILE] [-l LOGFILE] [-o OUTPUTDIR] [--skip-root-items] [--format] [--time-out=SECS] - 显示帮助信息
