如何得到oracle心跳网络流量趋势图
在dbconsole 能看到趋势图，如何通过数据字典得到这个趋势图呢？ key word : AWR db_hist table & interconnect bandwidthODM Data:
dba_hist_ic_client_stats
DBA_HIST_IC_CLIENT_STATS displays information about the usage of an interconnect device by the instance. The information is divided into several areas of the Oracle Database, each identified by the NAME value.
Column Datatype NULL Description
SNAP_ID NUMBER NOT NULL Unique snapshot ID
DBID NUMBER NOT NULL Database ID for the snapshot
INSTANCE_NUMBER NUMBER NOT NULL Instance number for the snapshot
NAME VARCHAR2(9) NOT NULL Identifies the area of the Oracle Database:
ipq - Parallel query communications
dlm - Database lock management
cache - Global cache communications
All other values are internal to Oracle and are not expected to have high usage.
BYTES_SENT NUMBER Number of bytes sent by the instance since instance startup for the software area identified by NAME. This information is aggregated across all devices used by the instance.
BYTES_RECEIVED NUMBER Number of bytes received by the instance since instance startup for the software area identified by NAME. This information is aggregated across all devices used by the instance. another view dba_hist_ic_device_stats in 11gR2
DBA_HIST_IC_DEVICE_STATS displays operating system information about the usage of interconnect devices by the machine. This usage contains Oracle usage but is not limited to it. The quality of the information depends on the operating system.SQL> select * from v$version;

6 rows selected 你这个结果，是使用2单独个网卡作为心跳，请问，这2个网卡是不是分别连接在2个交换机上面？ 对于 Oracle 而言 它只感知到 网络接口 network interface的信息 ： eth0 eth1:1 这种； 对于实际的 物理拓扑信息 oracle无从得知。 Liu Maclean(刘相兵 发表于 2012-1-19 23:10 static/image/common/back.gif

刘大，请问下，DBA_HIST_IC_DEVICE_STATS 或者DBA_HIST_IC_CLIENT_STATS，为什么只有历史表，当前的信息就没有一个对应的视图可以查看实时的吗？
