前言
smokeping页面和rrd图片支持中文
最近搭建了机房内网互通，急需要监控网络的质量，经过同事的推荐，体验了一下smokeping这款开源软件。其中我认为最大的亮点是支持分布式监控，master/slaves，多个节点的监控数据可以在同一个图上展现。事不宜迟，开始介绍部署吧、
部署1.master的部署
master负责提供web界面，cgi接口。其中也有些坑后面会讲述。
a.先加入epel，rpmforge的源吧，方便yum安装
rpm –Uvh http://mirrors.neusoft.edu.cn/epel/6/i386/epel-release-6-8.noarch.rpm rpm –Uvh http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-1.el6.rf.x86_64.rpm
b.安装依赖包
yum -y install httpd fping echoping curl rrdtool perl perl-Net-Telnet perl-Net-DNS perl-LDAP perl-libwww-perl perl-RadiusPerl perl-IO-Socket-SSL perl-Socket6 perl-CGI-SpeedyCGI perl-devel perl-FCGI.x86_64 perl-CGI.x86_64 rrdtool-perl.x86_64
c.有一个perl模块找不到rpm，用CPAN装上吧
wget http://search.cpan.org/CPAN/authors/id/D/DS/DSCHWEI/Config-Grammar-1.10.tar.gz tar -zxvf Config-Grammar-1.10.tar.gz cd Config-Grammar-1.10 perl Makefile.PL make && make install
d.开始安装smokeping
wget http://oss.oetiker.ch/smokeping/pub/smokeping-2.6.9.tar.gz tar -zxvf smokeping-2.6.9.tar.gz cd smokeping-2.6.9 ./configure make && make install
e.初始化环境
cp /opt/smokeping-2.6.9/etc/config.dist /opt/smokeping-2.6.9/etc/config mkdir -p /opt/smokeping-2.6.9/cache mkdir -p /opt/smokeping-2.6.9/data mkdir -p /opt/smokeping-2.6.9/var chmod 400 /opt/smokeping-2.6.9/etc/smokeping_secrets.dist #这个密钥用于master与slaves验证用，后面会说 chown apache.apache /opt/smokeping-2.6.9/etc/smokeping_secrets.dist chown apache.apache -R /opt/smokeping-2.6.9/
f.配置apache
vim /etc/httpd/conf.d/smokeping.conf
Alias /smokeping/cache/ /opt/smokeping-2.6.9/cache/ Alias /smokeping/ /opt/smokeping-2.6.9/htdocs/ <Directory /opt/smokeping-2.6.9/htdocs/> Allow from all Options ExecCGI AddHandler cgi-script .fcgi <IfModule dir_module> DirectoryIndex smokeping.fcgi </IfModule> </Directory>
g.单节点的部署完了，测试跑一下
/etc/init.d/httpd start sudo -u apache /opt/smokeping-2.6.9/bin/smokeping
2.部署master/slaves
现在开始部署分布式监控
需要注意以下几点：
1）smokeping的slaves机器不需要配置httpd且不需要配置文件，它会去master上取。
2）master与slaves需要通过校验文件校验
3）master的httpd进程必须与smokeping进程是相同的启动用户（在本文用apache用户）。不然会出现slaves采集的数据，一直不会更新rrd.图上一直是Nan
a.master端
1)在master上添加配置,添加以下内容到配置文件
/opt/smokeping-2.6.9/etc/config
*** Slaves *** #此文件就是校验文件 secrets=/opt/smokeping-2.6.9/etc/smokeping_secrets.dist + 节点的hostname display_name=节点的hostname location=China color=0000ff
2)生成master校验文件
vim /opt/smokeping-2.6.9/etc/smokeping_secrets.dist
节点的hostname:密钥
3)重启smokeping服务
b.在slaves端
和master一样安装包和初始化环境，这里就不重复了
1）生成slaves的校验文件
echo "上面master校验文件中定义的密钥" > /opt/smokeping-2.6.9/etc/slave_secret.txt chmod 400 /opt/smokeping-2.6.9/etc/slave_secret.txt
2)启动slaves服务
注意：
slaves的hostname必须与master校验文件和配置文件中的对上
/opt/smokeping-2.6.9/bin/smokeping --master-url=http://你的masterIP/smokeping/smokeping.fcgi --shared-secret=/opt/smokeping-2.6.9/etc/slave_secret.txt --cache-dir=/opt/smokeping-2.6.9/cache/
master的配置文件参考

默认不支持中文，不过修改也很简单
1.页面支持中文
在配置文件的*** Presentation ***下添加
charset = utf-8
2.rrd图片支持中文
yum -y install wqy-zenhei-fonts.noarch
修改配置文件/opt/smokeping-2.6.9/lib/Smokeping/Graphs.pm ,插入这句'--font TITLE:20:"WenQuanYi Zen Hei Mono"',
my ($graphret,$xs,$ys) = RRDs::graph
("dummy",
'--start', $tasks[0][1],
'--end', $tasks[0][2],
'--font TITLE:20:"WenQuanYi Zen Hei Mono"',

'PRINT:maxping:MAX:%le' );
