smokeping網絡監控

一、smokeping介紹

　　我們在選擇機房的時候，如何知道這個機房的網絡情況，這個時候就要用到網絡監控軟件:smokeping　　

　　本文主要介紹如何使用smokeping來監控idc機房的網絡質量情況，從監控圖上的延時與丟包能分辨出你機房的網絡是否穩定，是否為多線，是否為BGP機房，到各城市的3個運營商之間的網絡，各是什么情況，如果出現問題，如何有針對性的解決。而且如果選擇新機房的時候，你可以根據smokeping的監控結果來判斷這個機房是否適合。

smokeping是rrdtool的作者Tobi Oetiker的作品，所以它在圖形顯示方面有很大優勢，也是一個很 有特點的opensource工具：

1、多種探測方式，包括fping、echoping、dig、curl等；
2、易用可擴展的插件；
3、master/slave 的 工作方式，可以在多個節點收集同一個監測點的數據；

 

二、安裝smokeping

1、軟件環境：

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

2、下載軟件

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、安裝軟件

1、安裝依賴包：

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、解壓、編譯安裝fping

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

3、解壓、編譯安裝echoping

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

4、解壓、編譯安裝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
主要修改如下內容：
#cgiurl = http://some.url/smokeping.cgi
cgiurl = http://192.168.30.128/smokeping.cgi

*** Database ***
#step = 300
step = 60 #此處建議改為 60 ， 一分鍾采集一次數據
pings = 20

7、編輯apache配置文件

vim /etc/httpd/conf/httpd.conf
#在結尾添加如下代碼：

#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、圖像瀏覽界面的中文支持
安裝字體

yum -y install wqy-zenhei-fonts.noarch

編輯smokeping的配置文件

vim /usr/local/smokeping/etc/config

*** Presentation ***
charset = UTF-8  #添加這行，解決出圖亂碼問題
template = /usr/local/smokeping/etc/basepage.html.dist

編輯Graphs.pm

vi /usr/local/smokeping/lib/Smokeping/Graphs.pm
#在第147行，下邊插入這一行代碼

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

如下圖代碼，標紅部分

    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、##########測試數據可自定義##########

10、smokeping的默認配置文件110行的fping安裝目錄與此次安裝目錄不相符需修改！

vi /usr/local/smokeping/etc/config

#第110更改fping的目錄為
binary = /usr/local/sbin/fping

11、啟動apache服務和smokeping服務

#啟動apache服務

  [root@smokeping ~]# /etc/init.d/httpd start
  正在啟動 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
  [確定]

#重啟apache服務
[root@smokeping ~]# /etc/init.d/httpd restart
停止 httpd：[確定]
正在啟動 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


#啟動smokeping
/usr/local/smokeping/bin/smokeping


#檢查
[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

#殺smokeping進程號
[root@smokeping ~]# kill -9 66206
[root@smokeping ~]# kill -9 66206
-bash: kill: (66206) - 沒有那個進程

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

12、設置環境變量

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

 

三、用數據說話（三大運營商網絡監測圖）

1、訪問網站

2、監控統計圖
