摘要：本文主要着重介绍资源池资源监控以及用户资源监控。

本文分享自华为云社区《​ ​GaussDB(DWS)资源监控之用户、队列资源监控​​》，作者： 一只菜菜鸟。

GaussDB(DWS)资源监控功能包含实例资源监控、内存资源监控、资源池资源监控、查询监控以及用户资源监控，本文主要着重介绍资源池资源监控以及用户资源监控；

用户是使用数据库系统以及执行业务的主要手段，在GaussDB(DWS)中将用户场景分为两种方案，分别是普通方案以及多租户方案；为了更好的使用GaussDB(DWS)的资源分组管理，建议依托多租户场景构造具体的使用情况；

多租户引入了两级用户机制，分别为组用户以及业务用户；两级用户分别关联不同的资源池以及存储空间；

详解GaussDB(DWS) 资源监控_存储空间

1、创建组用户关联到组资源池

CREATE USER user_g RESOURCE POOL 'respool_g1' PASSWORD 'Gauss_234';



2、创建业务用户关联到业务资源池



CREATE USER user_1 RESOURCE POOL 'respool_g1' USER GROUP 'user_g' PASSWORD 'Gauss_234';



注：创建业务用户时，业务资源池（resource pool）和组用户（user group）为必选字段；



用户资源监控



用户资源监控中记录所有用户使用资源（内存、CPU核数、存储空间、临时空间、算子落盘以及IO）的实时使用情况，也可以通过查询历史表访问用户资源的历史使用情况；

资源池资源监控



多租户场景下，用户关联资源池执行业务，其消耗的资源汇总到其对应的资源池上，可以通过资源池资源监控视图，实时查看其相应数值，以及历史表记录的资源历史使用情况；
