smokeping简介
smokeping是一款监控网络状态和稳定性的开源软件（它是rrdtool的作者开发的），通过它可以监控到公司IDC的网络状况，如延时，丢包率，是否BGP多线等；
smokeping会向目标设备和系统发送各种类型的测试数据包，测量、记录，并通过rrdtool制图方式，图形化地展示网络的时延情况，进而能够清楚的判断出网络的即时通信情况；
通过smokeping来监控IDC机房网络质量情况，可以从监控图上的延时与丢包情况分辨出机房的网络是否稳定，是否为多线，是否为BGP机房以及到各城市的三个运行商网络各是什么情况。如果出现问题，可以有针对性的去处理；如果选择新机房的时候，还可以根据smokeping的监控结果来判断这个机房是否适合。
需要注意的是：smokeping监控的是网络稳定性，而cacti或zabbix监控的是带宽使用情况（即进出口流量）、
smokeping部署过程
安装smokeping的依赖包

部署smokeping
[[email protected] ~]# cd /usr/local/src/ #进入默认源码包存放路径 [[email protected] ~]# wget http://oss.oetiker.ch/smokeping/pub/smokeping-2.6.9.tar.gz #下载smokeping包 [[email protected] src]# tar xf smokeping-2.6.9.tar.gz #解压smokeping [[email protected] src]# cd smokeping-2.6.9 [[email protected] smokeping-2.6.9]# ./setup/build-perl-modules.sh /usr/local/smokeping/thirdparty [[email protected] smokeping-2.6.9]# ./configure --prefix=/usr/local/smokeping #编译smokeping到/usr/local [[email protected] smokeping-2.6.9]# /usr/bin/gmake install [[email protected] smokeping-2.6.9]# cd /usr/local/smokeping/ #进入smokeping目录 [[email protected] smokeping]# mkdir cache data var #创建三个目录 [[email protected] smokeping]# touch /var/log/smokeping.log #创建smokeping日志文件 [[email protected] smokeping]# chown apache.apache cache/ data/ var/ /var/log/smokeping.log #授权属主属组为apache [[email protected] smokeping]# cd /usr/local/smokeping/htdocs/ #进入smokeping下htdocs目录 [[email protected] htdocs]# mv smokeping.fcgi.dist smokeping.fcgi #修改smokeping文件名 [[email protected] smokeping]# mv /usr/local/smokeping/etc/config.dist /usr/local/smokeping/etc/config #修改smokeping配置文件名称
修改smokeping配置文件如下：
[[email protected] smokeping]# vim /usr/local/smokeping/etc/config cgiurl = http://192.168.1.120/smokeping.cgi #配置smokeping主机地址 *** Database *** step = 60 #默认检测时间300秒修改60秒 pings = 60 #默认ping20次，修改为60秒ping60次 *** Presentation *** charset = utf-8 #在presentation添加utf-8中文字符集
修改smokeping密码文件的权限为root
[[email protected] smokeping]# chmod 600 /usr/local/smokeping/etc/smokeping_secrets.dist
设置smokeping登录密码认证
[[email protected] htdocs]# htpasswd -c /usr/local/smokeping/htdocs/htpasswd darker New password: Re-type new password: Adding password for user darker
修改apache的配置文件，配置smokeping的站点
[[email protected] ~]# vim /etc/httpd/conf/httpd.conf #ServerName www.example.com:80 # 在此行下面添加如下一行，不然启动会报错 ServerName localhost:80 DocumentRoot "/var/www/html" #在这行下面添加如下---标红的代表密码验证 Alias /cache "/usr/local/smokeping/cache/" Alias /cropper "/usr/local/smokeping/htdocs/cropper/" Alias /smokeping "/usr/local/smokeping/htdocs/smokeping.fcgi" <Directory "/usr/local/smokeping"> AllowOverride None Options All AddHandler cgi-script .fcgi .cgi Order allow,deny Allow from all AuthName "Smokeping" AuthType Basic AuthUserFile /usr/local/smokeping/htdocs/htpasswd Require valid-user DirectoryIndex smokeping.fcgi </Directory>
创建smokeping的启动脚本，让smokeping可以启动、停止、重启、开机自启动等
[[email protected] ~]# cat /etc/init.d/smokeping #!/bin/bash # # chkconfig: 2345 80 05 # Description: Smokeping init.d script # Write by : goser # Get function from functions library . /etc/init.d/functions # Start the service Smokeping function start() { echo -n "Starting Smokeping: " /usr/local/smokeping/bin/smokeping >/dev/null 2>&1 ### Create the lock file ### touch /var/lock/subsys/smokeping success $"Smokeping startup" echo } # Restart the service Smokeping function stop() { echo -n "Stopping Smokeping: " kill -9 `ps ax |grep "/usr/local/smokeping/bin/smokeping" | grep -v grep | awk ‘{ print $1 }‘` >/dev/null 2>&1 ### Now, delete the lock file ### rm -f /var/lock/subsys/smokeping success $"Smokeping shutdown" echo } #Show status about Smokeping function status() { NUM="`ps -ef|grep smokeping|grep -v grep|wc -l`" if [ "$NUM" == "0" ];then echo "Smokeping is not run" else echo "Smokeping is running" fi } ### main logic ### case "$1" in start) start ;; stop) stop ;; status) status ;; restart|reload) stop start ;; *) echo $"Usage: $0 {start|stop|restart|reload|status}" exit 1 ;; esac exit 0
启动httpd、smokeping服务并设置其开机自启动
[[email protected] ~]# chmod 755 /etc/init.d/smokeping #添加脚本755权限 [[email protected] ~]# chkconfig --add smokeping #将smokeping加入开机启动 [[email protected] ~]# chkconfig smokeping on #设置smokeping为开机启动 [[email protected] ~]# chkconfig httpd on #设置apache为开机启动 [[email protected] ~]# /etc/init.d/httpd start #启动apache服务 [[email protected] ~]# /etc/init.d/smokeping start #启动smokeping服务
添加需要监控网络状态的站点或服务主机
要添加站点或主机ip地址的话，只能再smokeping的配置文件中添加，无法通过smokeping的web界面添加，在添加完站点后重启smokeping，会在在/usr/local/smokeping/data 之下添加moniter文件夹，其下包含website子文件夹
注意添加监控节点方式为：+是第一层，++是第二层，+++ 是第三层
+ Other menu = 三大网络监控 title = 监控统计 ++ dianxin menu = 电信网络监控 title = 电信网络监控列表 host = /Other/dianxin/dianxin-bj /Other/dianxin/dianxin-hlj /Other/dianxin/dianxin-tj /Other/dianxin/dianxin-sc /Other/dianxin/dianxin-sh /Other/dianxin/dianxin-gz +++ dianxin-bj menu = 北京电信 title = 北京电信 alerts = someloss host = 202.96.199.133 +++ dianxin-hlj menu = 黑龙江电信 title = 黑龙江电信 alerts = someloss host = 219.147.198.242 +++ dianxin-tj menu = 天津电信 title = 天津电信 alerts = someloss host = 219.150.32.132 +++ dianxin-sc menu = 四川电信 title = 四川电信 alerts = someloss host = 61.139.2.69 +++ dianxin-sh menu = 上海电信 title = 上海电信 alerts = someloss host = 116.228.111.118 +++ dianxin-gz menu = 广东电信 title = 广东电信 alerts = someloss host = 113.111.211.22 ++ liantong menu = 联通网络监控 title = 联通网络监控列表 host = /Other/liantong/liantong-bj /Other/liantong/liantong-hlj /Other/liantong/liantong-tj /Other/liantong/liantong-sc /Other/liantong/liantong-sh /Other/liantong/liantong-gz +++ liantong-bj menu = 北京联通 title = 北京联通 alerts = someloss host = 61.135.169.121 +++ liantong-hlj menu = 黑龙江联通 title = 黑龙江联通 alerts = someloss host = 202.97.224.69 +++ liantong-tj menu = 天津联通 title = 天津联通 alerts = someloss host = 202.99.96.68 +++ liantong-sc menu = 四川联通 title = 四川联通 alerts = someloss host = 119.6.6.6 +++ liantong-sh menu = 上海联通 title = 上海联通 alerts = someloss host = 210.22.84.3 +++ liantong-gz menu = 广东联通 title = 广东联通 alerts = someloss host = 221.5.88.88 ++ yidong menu = 移动网络监控 title = 移动网络监控列表 host = /Other/yidong/yidong-bj /Other/yidong/yidong-hlj /Other/yidong/yidong-tj /Other/yidong/yidong-sc /Other/yidong/yidong-sh /Other/yidong/yidong-gz +++ yidong-bj menu = 北京移动 title = 北京移动 alerts = someloss host = 221.130.33.52 +++ yidong-hlj menu = 黑龙江移动 title = 黑龙江移动 alerts = someloss host = 211.137.241.35 +++ yidong-tj menu = 天津移动 title = 天津移动 alerts = someloss host = 211.137.160.5 +++ yidong-sc menu = 四川移动 title = 四川移动 alerts = someloss host = 218.201.4.3 +++ yidong-sh menu = 上海移动 title = 上海移动 alerts = someloss host = 117.131.19.23 +++ yidong-gz menu = 广东移动 title = 广东移动 alerts = someloss host = 211.136.192.6
要是添加的站点生效，必须重启smokeping服务（因为修改了smokeping的配置文件）
[[email protected] smokeping]# /etc/init.d/smokeping restart
最后通过浏览器访问smokeping监控页面：http://192.168.1.120/smokeping 这时候页面可能会显示乱码，这是因为没有加载中文字体，接下来为smokeping添加一个字体
安装字体：yum -y install wqy-zenhei-fonts.noarch
编辑Graphs.pm：
vim /usr/local/smokeping/lib/Smokeping/Graphs.pm #第147行下边插入下边一行 ‘--font TITLE:20:"WenQuanYi Zen Hei Mono"‘,
这样再刷新页面后，中文便显示正常，显示的smokeping页面如下：
