Oracle Enterprise Manager 在单独的窗口中导出对更多数据库的实时监控

Question

我正在使用 Oracle Cloud Manager 13c。 我有很多数据库，但我只想跟踪五六个重要数据库的 CPU 负载。

我看到了性能中心，当我单击目标数据库时，我可以在其中看到负载和性能，在其中我们可以看到 CPU 负载与活动会话的图表。

由于我需要单击每个数据库才能获取该输出，我想知道是否可以进行某种导出（例如单独的活动 html 页面）以将所有数据库放在一个地方（例如摘要）？

提前致谢。

您可以假脱机到 *.csv CPU 使用率指标，然后根据需要在 html 页面中可视化数据。

oracle sqlplus 1020.sql 的 SQL 查询示例：

    set pagesize 10000
    set head on
    
    SET COLSEP ','
    set UNDERLINE off
    set linesize 10000
    set trimout on
    set echo off
    set verify off
    set feedback off
    set timing off
    set markup html OFF
    
    
    SET TERMOUT OFF
    
    alter session set nls_date_format='YYYY/MM/DD HH24:MI:SS';

spool 1020.csv
