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@MJ-Zabbix ~]# cat /etc/redhat-release 

CentOS release 6.9 (Final)

[root@MJ-Zabbix ~]# uname -r

2.6.32-696.1.1.el6.x86_64

[root@MJ-Zabbix ~]# 

2、软件下载

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://10.0.0.62/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

#结尾最后边添加如下代码：

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

第50行添加

charset = utf-8 #添加此行，解决出图乱码问题

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"',

设置开机启动：

echo "/usr/local/smokeping/bin/smokeping --logfile=/var/log/smokeping.log 2>&1 &" >> /etc/rc.local

#########################################################

 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、Config 配置文件的最后边

vim /usr/local/smokeping/etc/config

10.启动服务：

httpd:

[root@MJ-Zabbix etc]# /etc/init.d/httpd restart

Stopping httpd:                                            [  OK  ]

Starting httpd:                                            [  OK  ]

11.启动问题

smokeping:

[root@MJ-Zabbix etc]# /usr/local/smokeping/bin/smokeping    看到如下信息说明smokeping 配置无问题，可出图

Note: logging to syslog as local0/info.

Daemonizing /usr/local/smokeping/bin/smokeping ...

如果启动有问题：

1、File '/usr/local/smokeping/etc/smokeping_secrets.dist' is world-readable

2、ERROR: /usr/local/smokeping/bin/../etc/config, line 112: File '/usr/local/smokeping/etc/smokeping_secrets.dist' is world-readable or writable, refusing it

查看smokeping_secrets.dist文件属性是否为400，如不是请按照如下修改：

[root@MJ-Zabbix etc]# ll

total 24

-rw-r--r-- 1 root root 2041 Feb 27 17:21 basepage.html.dist

-rw-r--r-- 1 root root 3829 Mar  1 10:19 config

drwxr-xr-x 2 root root 4096 Feb 27 17:21 examples

-rw-r--r-- 1 root root 1563 Feb 27 17:21 smokemail.dist

-rw-r--r-- 1 root root   59 Feb 27 17:21 smokeping_secrets.dist

-rw-r--r-- 1 root root 3815 Feb 27 17:21 tmail.dist

注意etc/smokeping_secrets.dist文件属性必须400

chmod 400 smokeping_secrets.dist    修改权限

/usr/local/smokeping/bin/smokeping  --check   检查语法

[root@MJ-Zabbix etc]# ps -ef |grep smokeping

root     15946     1  0 10:20 ?        00:00:02 /usr/local/smokeping/bin/smokeping [FPing]

root     21066 20350  0 11:49 pts/1    00:00:00 grep smokeping

注意：每次修改smokeping配置文件/usr/local/smokeping/etc/config都要先杀进程，然后重启服务才生效

[root@MJ-Zabbix etc]# kill -9 15946     

[root@MJ-Zabbix etc]# /usr/local/smokeping/bin/smokeping

Note: logging to syslog as local0/info.

Daemonizing /usr/local/smokeping/bin/smokeping ...

12. Zabbix和Smokeping部署在同一台服务器，占用端口80

修改端口80为8080,重启httpd服务

[root@MJ-Zabbix /]# cd /etc/httpd/conf/http.conf



13、验证测试：

10.2.66.200:8080/zabbix

10.2.66.200:8080/smokeping



############################

补充：

14、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！

vim /usr/local/smokeping/etc/config

#第110更改fping的目录为

binary = /usr/local/sbin/fping

15、启动apache和smokeping&设置环境变量

/etc/init.d/httpd start

/usr/local/smokeping/bin/smokeping

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