linux信息收集篇之supportconfig
由于工作原因，平时需要suse的工程师做二线技术支持，除了经常会提交kdump分析的结果给suse 工程师定位根因。而在没有kdump生成时，经常会用的指令就是supportconfig收集系统信息。其收集内容基本涵盖了内核、模块、系统、服务等几乎所有我们能想到的信息，另外还会出一份简单的health check报告，其除了适用于suse企业版外，同样在opensuse上也可以使用。本篇就结合现网使用的场景对supportconfig命令做一个简单的概括。
一、supportconfig的安装
可以通过yast进行安装，也可以通过zypper命令进行安装，安装命令如下：
1直接使用源进行安装
2#zypper install supportutils
3也可以将rpm包下载下来使用yast进行安装或者在yast的管理界面里查找安装
4#yast install supportutils-xxx.rpm
注：根据系统的版本不同，包名也可能是supportconfig 。
安装完成后可以使用rpm -ql supportutils 查看包中具体包含的文件信息，如下：
1# rpm -ql supportutils
2/etc/schealth.conf
3/etc/supportconfig.conf
4/sbin/chkbin
5/sbin/supportconfig
6/usr/bin/schealth
7/usr/share/man/man5/supportconfig.conf.5.gz
8/usr/share/man/man8/chkbin.8.gz
9/usr/share/man/man8/supportconfig.8.gz
注：上面的结果是在 suse11 sp1企业版上的测试的结果，在opensuse 13上目录结构会略有不同，其上使用的是新版本的supportconfig。

上面的报告中，我们发现kernel Tainted 状态为red ，该处是通过cat /proc/sys/kernel/tainted 进行判断的，如果值不为0，则是内核受到污染 ，显的值不同，具体可以参看/usr/src/linux/Documentation/sysctl/kernel 文件（具体的值不一样，代表的意义也不一样）。64报红是由于加载了非系统官方或非开源的模块所致（ Unsupported modules loaded）。

五、supportconfig总结
supportconfig是使用shell 编写的一个功能十分强大的工具，具体可以通过vim /sbin/supportconfig 查看 。同时，由于linux命令上的通用性，我们甚至可以很简单的进行修改后将其移植到其他linux 发行版上。不过显然这是没必要的，因为还有一个比较通的用的开源工具sosreport和其作用差不多，而其适用性更强，后面会单独列一篇做一个总结。
