smokeping简介
smokeping是rrdtool的作者Tobi Oetiker的作品，用Perl语言写的，主要是监视网络性能，所以它在图形显示方面有很大优势，也是一个很有特点的opensource工具：多种探测方式，包括fping、echoping、dig、curl等；监视dns、ssh性能，底层也是rrdtool做支持，特点是画的图非常漂亮，网络丢包和延迟用颜色和阴影来表示，非常直观。同时也可以在多个节点收集同一个监测点的数据；很有特色的alert设置，不只是简单的设置一个阀值。

smokeping架构组件
主要有Rrdtool 、Fping 、 Echoping 、 Curl 、 Dig 、 SSH 、 Perl 模块、SpeedyCGI 、 Apache等
分布式功能
在使用smokeping功能时，从单个节点去探测网络性能是有缺陷的，smokeping提供了多个节点的分布式部署功能，可以从多个节点去探测某个地区网络回调并显示至主服务器，也就是smokeping的主从模式
特点
可视化的网络品质延迟。
交互式的图形浏览。
较多的网络测量插件。
主/从系统分布式测量。
高度可配置的警报系统。
直观的网络延迟图表。
自定义时间刷新图形显示。
缺点：
依赖包、组件过多，安装搭建配置较为繁琐。
图形参数较多，需要查阅相关文档
Alerts API
警报alerts接口可以调用外部程序，可传送5个相关参数：
警报名称 #eg:myloss
地址别名 #eg：Ustack.Publoc-google
loss规则 #eg:loss: S, 30%, 40%, 30%, 40%
延迟 #eg:rtt: S, 204ms, 200ms, 200ms, 200ms
ip地址 #eg:8.8.8.8
警报触发规则可参考官网说明 http://oss.oetiker.ch/smokeping/doc/smokeping_config.en.html
图形参数说明
RTT(Round-Trip Time)
Median RTT 中间数
Avg RTT 评价值
Avg pkt loss
Probe:10 ICMP Echo Pings(56 Bytes)every 30s
Smokeping 搭建
1、yum安装需要的软件包（若无法安装部分软件包，推荐用epel源）
* yum -y install freetypefreetype-devel fontconfig cairo cairo-devel libart_lgpl libart_lgpl-devel perl perl-Net-Telnet perl-Net-DNSperl-LDAP
* yum -y install perl-libwww-perl perl-RadiusPerl perl-IO-Socket-SSL perl-Socket6perl-CGI-SpeedyCGI rrdtool-perl

4、安装fping
* wget http://fping.sourceforge.net/download/fping.tar.gz
* tar zxf fping.tar.gz -C /usr/src/ && cd /usr/src/fping.XX

5、安装echoping
* wget http://jaist.dl.sourceforge.net/project/echoping/echoping/6.0.0/echoping-6.0.0.tar.gz
* tar zxf echoping-6.0.0.tar.gz -C /usr/src/ && cd /usr/src/echoping-XXX
* ./configure --without-libidn && make && make install
* 会有报错：configure: error: Missing popt library
* 解决：yum -y install popt-devel 即可
6、安装FCGI
* wget http://cpan.communilink.net/authors/id/F/FL/FLORA/FCGI-0.74.tar.gz
* tar zxf FCGI-0.74.tar.gz -C /usr/src/ && cd /usr/src/FCGI-XXX
* perl Makefile.PL && make && make install
7、安装mod_fastcgi
* wget http://www.fastcgi.com/dist/mod_fastcgi-2.4.6.tar.gz
* tar zxf mod_fastcgi-2.4.6.tar.gz -C /usr/src/ && cd /usr/src/mod_fastcgi.XXX
* apxs -o mod_fastcgi.so -c *.c && apxs -i -a -n fastcgi .libs/mod_fastcgi.so
8、安装Smokeping （注：会有问题，请看下面解决方案）
* wget http://oss.oetiker.ch/smokeping/pub/smokeping-2.6.8.tar.gz
* tar zxf smokeping-2.6.8.tar.gz -C /usr/src/ && cd /usr/src/smokeping-XXX
* ./configure --prefix=/usr/local/smokeping
* (报错：FCGI failed，CGI::Fast failed,config::Grammar failed ........)
* ./setup/build-perl-modules.sh /usr/local/smokeping/thirdparty （时间有些长,安装完即可）
* ./configure --prefix=/usr/local/smokeping
* /usr/bin/gmake install
文件创建及授权
cd /usr/local/smokeping/
mkdir cache data var
chown –R apache.apache cache data var
cd /usr/local/smokeping/htdocs/
cp smokeping.fcgi.dist smokeping.fcgi
cd /usr/local/smokeping/etc/
cp config.dist config
chmod 600 /usr/local/smokeping/etc/smokeping_secrets.dist
chown apache.root /usr/local/smokeping/etc/smokeping_secrets.dist #slave 需要用到次文件，权限需分明
ln -s /usr/local/smokeping/cache /usr/local/smokeping/htdocs/cache
vim /usr/local/smokeping/etc/config
找到binary = /usr/sbin/fping ——— binary = /usr/local/sbin/fping
vi /usr/local/smokeping/bin/smokeping
找到：use lib qw(); ———— use lib qw(/usr/local/rrdtool/lib/perl);

Apache的配置
vim /etc/httpd/conf/httpd.cof
添加
Alias /smokeping “/usr/local/smokeping/htdocs/smokeping.fcgi”
Alias /cache “/usr/local/smokeping/cache”
Alias /cropper “/usr/local/smokeping/htdocs/cropper/”
AllowOverride None
Options ExecCGI
AddHandler cgi-script .fcgi .cgi
Order allow,deny
Allow from all
DirectoryIndex smokeping.fcgi
slave 主机
slave搭建与master一致
slave不需要配置
唯一需要配置的是 smokeping_secrets.dist文件（保存的是密码，主服务器上保存的是用户名及密码，密码与之对应，客户端启动需要用户名）
启动： 若启动出错，可以–debug-daemon –logfile=file.txt 分析
客户端启动需要连接master的URL，确保公网可以访问
服务启动
Apache启动
