Linux下日志的采集和分析是一个非常重要的工作，一般厂商都会有自己独有的命令，我这边列举下常用的两个Linux厂商的收集命令(Redhat Linux以及SuSe Linux），便于收集后，对系统进行全面分析。
1. 基于redhat的日志收集
[root@openstack-01 etc]# sosreport sosreport (version 3.2) This command will collect diagnostic and configuration information from this CentOS Linux system and installed applications. An archive containing the collected information will be generated in /var/tmp/sos.NUmfab and may be provided to a CentOS support representative. Any information provided to CentOS will be treated in accordance with the published support policies at: https://www.centos.org/ The generated archive may contain data considered sensitive and its content should be reviewed by the originating organization before being passed to any third party. No changes will be made to system configuration. Press ENTER to continue, or CTRL-C to quit. Please enter your first initial and last name [openstack-01]: Please enter the case id that you are generating this report for []: Setting up archive ... Setting up plugins ... Running plugins. Please wait ... Running 114/114: yum... [plugin:openstack_swift] regex substitution failed for ‘/etc/swift/container.builder‘ with: ‘‘utf8‘ codec can‘t decode byte 0x80 in position 0: invalid start byte‘ [plugin:openstack_swift] regex substitution failed for ‘/etc/swift/container.ring.gz‘ with: ‘‘utf8‘ codec can‘t decode byte 0x8b in position 1: invalid start byte‘ Creating compressed archive... Your sosreport has been generated and saved in: /var/tmp/sosreport-openstack-01-20160603071544.tar.xz The checksum is: 757286aeba8b7ca78b0614547c4d58c9 Please send this file to your support representative.
2. 基于SUSE Linux下的日志收集
使用脚本supportconfig -A收集日志，日志路径会存在/var/log下。

If you cannot attach the tar ball to the SR, then email it to the engineer.=============================================================================--
然后我们可以根据收集的相关信息，对系统进行分析
