linux信息收集篇之supportconfig

2014年9月11日 发表评论 阅读评论

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:

直接使用源进行安装
#zypper install supportutils
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
#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:

# rpm -ql supportutils
/etc/schealth.conf
/etc/supportconfig.conf
/sbin/chkbin
/sbin/supportconfig
/usr/bin/schealth
/usr/share/man/man5/supportconfig.conf.5.gz
/usr/share/man/man8/chkbin.8.gz
/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。

二、supportconfig用法

以下是supportconfig的帮助输出

# supportconfig -h

     directory.
  -g Use gzip instead of the default bzip2 compression.
  -i <keyword list>
     Include keywords. A comma separated list of feature keywords that specify
     which features to include. Use -F to see a list of valid keywords.

     rpm, messages, y2logs
  -o Toggle listed features on or off
  -p Disable all plugins
  -q Add a uuid to the tar ball filename to ensure uniqueness
  -r <srnum>

     the tar ball to Novell
  -s Include full SLP service lists
  -t Target directory. Just save log files here, do not create tarball.
  -u Upload the tar ball to the specified VAR_OPTION_UPLOAD_TARGET.
  -v Performs an rpm -V for each installed rpm  NOTE: This takes a long time
     to complete
  -x <keyword list>

-----------------------------------------------------------------------------
  NOTE:
  This tool will create a tar ball in the /var/log directory. Please attach
  the log file tar ball to your open Service.  Request at the following URL:
  https://secure-support.novell.com/eService_enu
  If you cannot attach the tar ball to the SR, then email it to the engineer.
  Please submit bug fixes or comments via:

                          Script Date: 2010 04 02
=============================================================================

默认supportconfig或supportconfig -A执行后会将收集后的结果打包为一个nts_主机名_日期.tbz 文件,同时会生成一个以该文件名加.md5后缀的文件。

三、supportconfig常用示例

1、supportconfig -A 收集所有日志

Creating Tar Ball
==[ DONE ]===================================================================
  Log file tar ball: /var/log/nts_361way.com_140825_1504.tbz
  Log file size:     4.0M
  Log file md5sum:   484b111cda54ca04419facd82a1da7d7
  Please attach the log file tar ball to your open Service Request at the
  following URL:
  https://secure-support.novell.com/eService_enu
  You can also upload the tar ball to ftp.novell.com/incoming, or just use
  supportconfig -ur <srnum>, to upload the tar ball automatically.
  If you cannot attach the tar ball to the SR, then email it to the engineer.
=============================================================================

其他常用用法:

//以最小选项搜集所需的信息
# supportconfig -m
//在输出中包含附加的联系人信息
# supportconfig -E tux@example.org -N "Tux Penguin" -O "Penguin Inc." ...
//要查看完整的功能列表
# supportconfig -F
//仅收集某个模块的用法,如LVM相的信息
# supportconfig -i LVM
//-x 的功能与-i刚好相反,是排除某个模块不收集
# supportconfig -x LVM
//使用-U url 可以将收集的结果上传到服务器上,直接的服务有ftp, scp, http, https,如:
# supportconfig -A -U http://www.361way.com/files/

具体可以参看官方的  常用的supportconfig选项 部分 。

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)。

配置文件中列出了默认收集的模块信息,公司信息、邮件、电话及上传的服务器目录等。

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。
