smokeping网络监控

一、smokeping介绍

　　我们在选择机房的时候，如何知道这个机房的网络情况，这个时候就要用到网络监控软件:smokeping　　

　　本文主要介绍如何使用smokeping来监控idc机房的网络质量情况，从监控图上的延时与丢包能分辨出你机房的网络是否稳定，是否为多线，是否为BGP机房，到各城市的3个运营商之间的网络，各是什么情况，如果出现问题，如何有针对性的解决。而且如果选择新机房的时候，你可以根据smokeping的监控结果来判断这个机房是否适合。

smokeping是rrdtool的作者Tobi Oetiker的作品，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：

1、多种探测方式，包括fping、echoping、dig、curl等；
2、易用可扩展的插件；
3、master/slave 的 工作方式，可以在多个节点收集同一个监测点的数据；

二、安装smokeping

1、软件环境：

[root@smokeping ~]# cat /etc/redhat-release 
CentOS release 6.6 (Final)
[root@smokeping ~]# uname -r
2.6.32-504.el6.x86_64

2、下载软件

wget http://www.fping.org/dist/fping-3.10.tar.gz

wget https://fossies.org/linux/misc/old/echoping-6.0.2.tar.gz

wget http://oss.oetiker.ch/smokeping/pub/smokeping-2.6.9.tar.gz

3、安装软件

1、安装依赖包：

yum install perl perl-Net-Telnet perl-Net-DNS perl-LDAP perl-libwww-perl perl-IO-Socket-SSL perl-Socket6 perl-Time-HiRes perl-ExtUtils-MakeMaker rrdtool rrdtool-perl curl httpd httpd-devel gcc make wget libxml2-devel libpng-devel glib pango pango-devel freetype freetype-devel fontconfig cairo cairo-devel libart_lgpl libart_lgpl-devel popt popt-devel libidn libidn-devel -y

2、解压、编译安装fping

tar xf fping-3.10.tar.gz
cd fping-3.10
./configure
make && make install

3、解压、编译安装echoping

tar xf echoping-6.0.2.tar.gz
cd echoping-6.0.2
./configure
make && make install

4、解压、编译安装smokeping

tar xf smokeping-2.6.9.tar.gz
cd smokeping-2.6.9
./setup/build-perl-modules.sh /usr/local/smokeping/thirdparty
./configure --prefix=/usr/local/smokeping
/usr/bin/gmake install

5、配置 smokeping 

cd /usr/local/smokeping/
mkdir cache data var
touch /var/log/smokeping.log
chown apache:apache cache data var
chown apache:apache /var/log/smokeping.log
chmod 600 /usr/local/smokeping/etc/smokeping_secrets.dist
cd /usr/local/smokeping/htdocs
mv smokeping.fcgi.dist smokeping.fcgi
cd /usr/local/smokeping/etc
mv config.dist config

6、更改配置文件

vim /usr/local/smokeping/etc/config
主要修改如下内容：
#cgiurl = http://some.url/smokeping.cgi
cgiurl = http://192.168.30.128/smokeping.cgi

*** Database ***
#step = 300
step = 60 #此处建议改为 60 ， 一分钟采集一次数据
pings = 20

7、编辑apache配置文件

vim /etc/httpd/conf/httpd.conf
#在结尾添加如下代码：

#add smokeping configure file at 2017-04-10
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
DirectoryIndex smokeping.fcgi
</Directory>

8、图像浏览界面的中文支持
安装字体

yum -y install wqy-zenhei-fonts.noarch

编辑smokeping的配置文件

vim /usr/local/smokeping/etc/config

*** Presentation ***
charset = UTF-8  #添加这行，解决出图乱码问题
template = /usr/local/smokeping/etc/basepage.html.dist

编辑Graphs.pm

vi /usr/local/smokeping/lib/Smokeping/Graphs.pm
#在第147行，下边插入这一行代码

'--font TITLE:20:"WenQuanYi Zen Hei Mono"',

如下图代码，标红部分

    if ($mode =~ /[anc]/){
        my $val = 0;
        for my $host (@hosts){
            my ($graphret,$xs,$ys) = RRDs::graph
            ("dummy",
            '--start', $tasks[0][1],
            '--end', $tasks[0][2],
            "DEF:maxping=$cfg->{General}{datadir}${host}.rrd:median:AVERAGE",
            '--font TITLE:20:"WenQuanYi Zen Hei Mono"',
            'PRINT:maxping:MAX:%le' );
            my $ERROR = RRDs::error();
            return "<div>RRDtool did not understand your input: $ERROR.</div>" if $ERROR;
            $val = $graphret->[0] if $val < $graphret->[0];
        }
        $val = 1e-6 if $val =~ /nan/i;
        $max = { $tasks[0][1] => $val * 1.5 };
    }

9、##########测试数据可自定义##########

10、smokeping的默认配置文件110行的fping安装目录与此次安装目录不相符需修改！

vi /usr/local/smokeping/etc/config

#第110更改fping的目录为
binary = /usr/local/sbin/fping

11、启动apache服务和smokeping服务

#启动apache服务

  [root@smokeping ~]# /etc/init.d/httpd start
  正在启动 httpd：httpd: apr_sockaddr_info_get() failed for smokeping
  httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
  [确定]

#重启apache服务
[root@smokeping ~]# /etc/init.d/httpd restart
停止 httpd：[确定]
正在启动 httpd：httpd: apr_sockaddr_info_get() failed for smokeping
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName


#启动smokeping
/usr/local/smokeping/bin/smokeping


#检查
[root@smokeping ~]# ps -ef|grep smokeping
root      66206      1  0 23:47 ?        00:00:00 /usr/local/smokeping/bin/smokeping [FPing]
root      66476   1586  0 23:58 pts/0    00:00:00 grep smokeping

#杀smokeping进程号
[root@smokeping ~]# kill -9 66206
[root@smokeping ~]# kill -9 66206
-bash: kill: (66206) - 没有那个进程

#再启动smokeping
[root@smokeping ~]# /usr/local/smokeping/bin/smokeping
Note: logging to syslog as local0/info.
Daemonizing /usr/local/smokeping/bin/smokeping ...

12、设置环境变量

echo 'export PATH=/usr/local/smokeping/bin/:$PATH' >> /etc/profile

三、用数据说话（三大运营商网络监测图）

1、访问网站

http://192.168.30.128/smokeping　

2、监控统计图
