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@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
