每个Exadata的数据库服务器和存储服务器节点都安装了sundiag.sh脚本（MOS:761868.1）

我们执行下：

[root@erpdb01 ~]# find /opt -name sundiag.sh
/opt/oracle.SupportTools/sundiag.sh
[root@erpdb01 ~]#

[root@erpdb01 oracle.SupportTools]# sh sundiag.sh
Oracle Exadata Database Machine - Diagnostics Collection Tool
Gathering Linux information

Skipping ILOM collection. Use the ilom or snapshot options, or login to ILOM
over the network and run Snapshot separately if necessary.

/tmp/sundiag_erpdb01_1338NML05G_2015_12_21_16_03
Generating diagnostics tarball and removing temp directory

==============================================================================
Done. The report files are bzip2 compressed in /tmp/sundiag_erpdb01_1338NML05G_2015_12_21_16_03.tar.bz2
==============================================================================
[root@erpdb01 oracle.SupportTools]# pwd
/opt/oracle.SupportTools
[root@erpdb01 oracle.SupportTools]#

文件 /tmp/sundiag_erpdb01_1338NML05G_2015_12_21_16_03.tar.bz2正常也就4M左右，解压后十多M不会很大

注：此BZ2包里包含很多的目录和文件，可以根据需要了解的信息直接搜索文件名

messages：这个就时系统/var/log/messages文件的一个副本，该文件由syslog进程维护，

包括操作系统各类操作与健康情况的重要信息
