sosreport
sosreport是一個類型于supportconfig 的工具，sosreport是python編寫的一個工具，適用于centos（和redhat一樣，包名為sos）、ubuntu（其下包名為sosreport）等大多數(shù)版本的linux 。sosreport在github上的托管頁面為：https://github.com/sosreport/sos ，而且默認在很多系統(tǒng)的源里都已經(jīng)集成有。如果使用的是正版redhat，在出現(xiàn)系統(tǒng)問題，尋求官方支持時，官方一般也會通過sosreport將收集的信息進行分析查看。需要注意的是在一些老的redhat發(fā)行版中叫sysreport ------ 如redhat4.5之前的版本中。
一、sosreport的安裝
在默認使用linux發(fā)行版的源進行安裝時，由于在不同的系統(tǒng)上包名稱也會有差異，所以使用的命令也不同，如redhat和ubuntu平臺的安裝如下：
// redhat/centos下的安裝
# yum -y insatll sos
// ubuntu下的安裝
# sudo apt-get install sosreport
二、sosreport用法
可以使用sosreport --help或man sosreport 獲取使用幫助手冊，如下：
[root@361way ~]# sosreport --help
Usage: sosreport [options]
Options:
-h, --help show this help message and exit
-l, --list-plugins list plugins and available plugin options
-n NOPLUGINS, --skip-plugins=NOPLUGINS
disable these plugins
-e ENABLEPLUGINS, --enable-plugins=ENABLEPLUGINS
enable these plugins
-o ONLYPLUGINS, --only-plugins=ONLYPLUGINS
enable these plugins only
-k PLUGOPTS, --plugin-option=PLUGOPTS
plugin options in plugname.option=value format (see
-l)
-a, --alloptions enable all options for loaded plugins
--batch batch mode - do not prompt interactively
--build keep sos tree available and dont package results
-v, --verbose increase verbosity
--quiet only print fatal errors
--debug enable interactive debugging using the python debugger
--ticket-number=TICKET_NUMBER
specify ticket number
--name=CUSTOMER_NAME specify report name
--config-file=CONFIG_FILE
specify alternate configuration file
--tmp-dir=TMP_DIR specify alternate temporary directory
--report Enable HTML/XML reporting
--profile turn on profiling
-z COMPRESSION_TYPE, --compression-type=COMPRESSION_TYPE
compression technology to use [auto, zip, gzip, bzip2,
xz] (default=auto)
Some examples:
enable cluster plugin only and collect dlm lockdumps:
# sosreport -o cluster -k cluster.lockdump
disable memory and samba plugins, turn off rpm -Va collection:
# sosreport -n memory,samba -k rpm.rpmva=off
上面也列出了具體操作的示例。其中-l 參數(shù)會列出當(dāng)前enable和disable的所有服務(wù)插件及當(dāng)前available的所有插件。
[root@361way log]# sosreport -a --report
sosreport (version 3.0)
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 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 [361way.com]:
Please enter the case number that you are generating this report for:
Running plugins. Please wait ...
Running 68/68: yum...
Creating compressed archive...
Your sosreport has been generated and saved in:
/var/tmp/sosreport-361way.com-20140912204339.tar.xz
The checksum is: eaf5b2cbb1e9be68d41be5e5a60a61b6
Please send this file to your support representative.
如上所示，我使用-A 啟用所有的模塊，--report是開啟所有的結(jié)果以html /xml 的格式一個總的報告。生成的包需要通過下面的命令進行解包。
# xz -d ***.tar.xz
# tar -xvf ***.tar
或直接使用下面的命令一步完成解壓
tar xvJf ***.tar.xz
在解包后的sos_reports 目錄會有report的結(jié)果sos.html文件生成，同時會有sos.txt文件生成，該文件內(nèi)列出了具體執(zhí)行的命令及copy 文件的一些信息。
由于頁面較大，這里只截出了最上面的部分，列出了所有的收集模塊，下面alerts 給出了報警模塊的信息。再往下就是具體到每一個模塊的信息。
三、sosreport配置文件
sosreport的配置文件是/etc/sos.conf ，默認內(nèi)容如下：
[root@361way ~]# cat /etc/sos.conf
[general]
#ftp_upload_url = ftp://example.com/incoming
#gpg_keyring = /usr/share/sos/rhsupport.pub
#gpg_recipient = support@redhat.com
smtp_server = None
[plugins] //此處可以設(shè)置默認enable和disable的模塊
#disable = rpm, selinux, dovecot
[tunables] //可調(diào)參數(shù)
#rpm.rpmva = off
#general.syslogsize = 15
從配置文件上可以看出，sosreport同樣將收集的結(jié)果上傳到server 上，可以通過man sos.conf 查看配置文件的幫助信息，不過man給出的并沒有太多信息，想在了解更多的信息可以查看 sosreport在github上的wiki頁 。
四、sosreport總結(jié)
相于supportconfig，由于sosreport是由python語言進行編寫的，所以其在功能擴展上更有優(yōu)勢，但由于在不同的發(fā)行版本上的python版本不同，在進行功能擴展時，對不同版本間的異常處理相對麻煩。而supportconfig由于是shell 語言編寫的一個工具，對版本的依賴相對少些 ，但對一些工具的依賴相對多些 ，如在獲取進程相關(guān)的信息時，shell 需要將ps 工具或處理proc的結(jié)果，而sosreport則可以直接import psutil 模塊，兩者之間的區(qū)別，歸根到底就是shell 和python的區(qū)別。
supportconfig
一、supportconfig的安裝
可以通過yast進行安裝，也可以通過zypper命令進行安裝，安裝命令如下：
直接使用源進行安裝
#zypper install supportutils
也可以將rpm包下載下來使用yast進行安裝或者在yast的管理界面里查找安裝
#yast install supportutils-xxx.rpm
注：根據(jù)系統(tǒng)的版本不同，包名也可能是supportconfig 。
安裝完成后可以使用rpm -ql supportutils 查看包中具體包含的文件信息，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：上面的結(jié)果是在 suse11 sp1企業(yè)版上的測試的結(jié)果，在opensuse 13上目錄結(jié)構(gòu)會略有不同，其上使用的是新版本的supportconfig。

五、supportconfig總結(jié)
supportconfig是使用shell 編寫的一個功能十分強大的工具，具體可以通過vim /sbin/supportconfig 查看 。同時，由于linux命令上的通用性，我們甚至可以很簡單的進行修改后將其移植到其他linux 發(fā)行版上。不過顯然這是沒必要的，因為還有一個比較通的用的開源工具sosreport和其作用差不多，而其適用性更強，后面會單獨列一篇做一個總結(jié)。
