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
| 代码如下 | 复制代码 |
| #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：
| 代码如下 | 复制代码 |
| # 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
| 代码如下 | 复制代码 |

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
| 代码如下 | 复制代码 |

具体可以参看官方的 常用的supportconfig选项 部分 。
supportconfig收集的系统健康报告：
| 代码如下 | 复制代码 |
| # supportconfig -A # cd /var/log # tar jxvf nts_361way.com_140825_1504.tbz # more basic-health-report.txt #==[ Command ]======================================# # /usr/bin/schealth -q ###################################################################### Supportconfig Health Check Report Tool v1.00-5 Date Checked: 09/12/14 04:40:37 ###################################################################### Health Check Files [ Green ] Processes Waiting for Run Queue [ Green ] Kernel Taint Status [ Red ] Kernel Tainted: 64 > 0 CPU Utilization [ Green ] Interrupts Per Second [ Green ] Context Switches Per Second [ Green ] Free Memory and Disk Swapping [ Green ] Used Disk Space [ Green ] Uninterruptible Processes [ Green ] Zombie Processes [ Green ] ###################################################################### Status: Red Flag Checked: /var/log/nts_361way.com_140825_1504/basic-health-check.txt Report: /var/log/nts_361way.com_140825_1504/basic-health-report.txt ###################################################################### |
|
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）。
四、supportconfig配置文件
supportconfig的默认配置文件是 /etc/supportconfig.conf ，其默认内容如下：
| 代码如下 | 复制代码 |
| # cat /etc/supportconfig.conf #################################### # Default Options #################################### OPTION_AFP=1 OPTION_APPARMOR=1 OPTION_AUDIT=1 OPTION_AUTOFS=1 OPTION_BOOT=1 OPTION_CHKCONFIG=1 OPTION_CIFS=1 OPTION_CIMOM=1 OPTION_CRASH=1 OPTION_CRON=1 OPTION_DFS=1 OPTION_DHCP=1 OPTION_DISK=1 OPTION_DNS=1 OPTION_EDIR=1 OPTION_ENV=1 OPTION_ETC=1 OPTION_EVMS=1 OPTION_HA=1 OPTION_HCREPORT=1 OPTION_IB=1 OPTION_ISCSI=1 OPTION_LDAP=1 OPTION_LUM=1 OPTION_LVM=1 OPTION_MEM=1 OPTION_MOD=1 OPTION_MPIO=1 OPTION_NCP=1 OPTION_NCS=1 OPTION_NET=1 OPTION_NFS=1 OPTION_NSS=1 OPTION_NTP=1 OPTION_OCFS2=1 OPTION_OFILES=1 OPTION_PAM=1 OPTION_PRINT=1 OPTION_PROC=1 OPTION_SAM=1 OPTION_SAR=1 OPTION_SLERT=1 OPTION_SLP=1 OPTION_SMART=0 OPTION_SMB=1 OPTION_SMS=1 OPTION_SMT=1 OPTION_SRAID=1 OPTION_SSH=1 OPTION_SYSCONFIG=1 OPTION_SYSFS=1 OPTION_UDEV=1 OPTION_UP=1 OPTION_UPD=1 OPTION_WEB=1 OPTION_X=1 OPTION_XEN=1 ADD_OPTION_EDIR=0 ADD_OPTION_FSLIST=0 ADD_OPTION_LOGS=0 ADD_OPTION_MINDISK=0 ADD_OPTION_MINYAST=0 ADD_OPTION_RPMV=0 ADD_OPTION_SLP=0 VAR_OPTION_BIN_TIMEOUT_SEC=300 VAR_OPTION_CONTACT_COMPANY="" VAR_OPTION_CONTACT_EMAIL="" VAR_OPTION_CONTACT_NAME="" VAR_OPTION_CONTACT_PHONE="" VAR_OPTION_CONTACT_STOREID="" VAR_OPTION_CONTACT_TERMINALID="" VAR_OPTION_CUSTOM_ARCH="" VAR_OPTION_GPG_UID="" VAR_OPTION_LINE_COUNT=500 VAR_OPTION_LOG_DIRS="/var/log /tmp" VAR_OPTION_MSG_MAXSIZE=500000 VAR_OPTION_PENGINE_FILES_LIMIT=250 VAR_OPTION_SAR_FILES_LIMIT=30 VAR_OPTION_SBM=0 VAR_OPTION_SILENT=0 VAR_OPTION_UNIQUE_FILE=0 VAR_OPTION_UPLOAD_ALT='https://secure-www.novell.com/upload?appname=supportconfig&file={tarball}' VAR_OPTION_UPLOAD_TARGET='ftp://ftp.novell.com/incoming' |
|
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。
