千家信息网最后更新 2024年10月19日分析ADG网卡流量出现规律性毛刺现象
一、介绍
客户ADG环境，刚上线的业务系统，通过ZABBIX进行监控，发现每半个小时会出现ADG网卡流量超过1M，持续2分钟后，平均网络流量在100K左右。
二、分析
1、ADG 环境备库流量主要来自主库redo的数据传输，或者出现网络问题，导致归档无法传输，恢复后归档日志的传输。
2、查看归档日志产生的频率及大小，检查告警日志是否有归档日志传输。
3、经过排查并未发现归档日志传输。检查数据库job,发现并没有客户创建的job。
4、检查系统自带的Job，dba_scheduler_jobs,我们会发现很多系统自带的job.
5、数据库自身自动写入的数据，而且有定时计划的可能会导致这个问题。
6、查看awr的写入的频率发现是每半个小时执行一次。
7、查看awrinfo.sql详细信息
以下是测试环境的的awrinfo.sql结果，大家需要熟悉了解。
