一款监控网络状态的好工具- Smokeping

       最近工作中需要监测某个分公司到IDC机房的网络情况，到网络上找了不少软件，发现一款叫smokeping的开源软件还不错，它是rrdtool的作者制作的，在图形显示方面很漂亮，可以用来很好的检测网络状态和稳定性。

下面介绍一下软件的安装配置方法：

一．安装软件
1.使用yum 命令安装所需的工具
 yum install gcc freetype-devel zlib-devel libpng-devel libart_lgpl-devel httpd-devel apr-util-devel apr-devel cairo cairo-devel pango pango-devel libxml2 libxml2-devel perl-XML-Simple.noarch perl-Crypt-SSLeay perl-Digest-HMAC

2. 安装rrdtool
wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.3.6.tar.gz
tar zxvf rrdtool-1.3.6.tar.gz
cd rrdtool-1.3.6
./configure --disable-tcl
make
make install

3. 安装cgilib
wget http://down1.chinaunix.net/distfiles/cgilib-0.5.tar.gz
tar zxvf cgilib-0.5.tar.gz
cd cgilib-0.5
make
cp libcgi.a /usr/local/lib
cp cgi.h /usr/include

4. 安装fping
wget http://fping.sourceforge.net/download/fping.tar.gz
tar zxvf fping.tar.gz
cd fping-2.4b2_to
./configure
make
make check
make install

5.安装 echoping
wget http://jaist.dl.sourceforge.net/project/echoping/echoping/6.0.0/echoping-6.0.0.tar.gz
tar zxvf echoping-6.0.0.tar.gz
cd echoping-6.0.0
./configure
make
make test
make install

6.安装 CGI-SpeedyCGI
wget ftp://195.220.108.108/linux/epel/5/x86_64/mod_speedycgi-2.22-4.el5.x86_64.rpm
wget ftp://ftp.muug.mb.ca/mirror/fedora/epel/5/x86_64/perl-CGI-SpeedyCGI-2.22-4.el5.x86_64.rpm
rpm -ivh --force perl-CGI-SpeedyCGI-2.22-4.el5.x86_64.rpm
rpm -ivh mod_speedycgi-2.22-4.el5.x86_64.rpm
wget http://mirrors.163.com/cpan/authors/id/H/HO/HORROCKS/CGI-SpeedyCGI-2.22.tar.gz
tar zxvf CGI-SpeedyCGI-2.22.tar.gz
cd CGI-SpeedyCGI-2.22
perl Makefile.PL
遇到问题选择默认选项（no）
make
make test
make install

7.安装smokeping
wget http://oss.oetiker.ch/smokeping/pub/smokeping-2.3.6.tar.gz
tar zxvf smokeping-2.3.6.tar.gz
mv smokeping-2.3.6 /usr/local/smokeping
cd /usr/local/smokeping

二．配置smokeping
1. 修改文件名
修改/usr/local/smokeping/bin下的smokeping.dist
cp smokeping.dist smokeping
修改etc/ 下的 basepage.html.dist，config.dist，smokemail.dist
cp basepage.html.dist basepage.html
cp config.dist config
cp smokemail.dist smokemail
chmod 600 smokeping_secrets.dist
修改htdoc/下的smokeping.cgi.dist
cp smokeping.cgi.dist smokeping.cgi

2. 修改配置文件

配置 bin/smokeping
vi /usr/local/smokeping/bin/smokeping
在这个文件里面我们需要修改前面两个 lib 和后面 config 文件的 path。
两个 lib 分别是 smokeping 的 lib 和 rrdtool 的 lib （红色为修改后的内容）
#!/usr/sepp/bin/perl-5.8.4 -w
#!/usr/bin/perl -w
use lib qw(/usr/pack/rrdtool-1.2.23-mo/lib/perl);
use lib qw(/usr/local/rrdtool-1.3.6/lib/perl);
use lib qw(lib);
use lib qw(/usr/local/smokeping/lib);
use Smokeping 2.003006;
Smokeping::main("etc/config.dist");
Smokeping::main("/usr/local/smokeping/etc/config");
配置 htdocs/smokeping.cgi,方法与上面相同
vi /usr/local/smokeping/htdocs/smokeping.cgi
************************
#!/usr/sepp/bin/speedy -w

#-*-perl-*-
#!/usr/bin/speedy -w
# -*-perl-*-
# use lib qw(/usr/pack/rrdtool-1.0.33-to/lib/perl);
use lib qw(/usr/local/rrdtool-1.3.6/lib/perl/);
# use lib qw(/home/oetiker/data/projects/AADJ-smokeping/dist/lib);
use lib qw(/usr/local/smokeping/lib);
use Smokeping 2.003006;
Smokeping::cgi("/home/oetiker/data/projects/AADJ-smokeping/dist/etc/config");
Smokeping::cgi("/usr/local/smokeping/etc/config");
配置 etc/config
vi usr/local/smokeping/etc/config   将以下几行替换为已经安装的相关软件的路径
*** General ***
imgcache = /home/oetiker/public_html/smokeping-ms/cache
imgcache = /usr/local/smokeping/htdocs/cache
imgurl = cache
imgurl = cache
datadir = /tmp/smokeping-ms/data
datadir = /usr/local/smokeping/var
piddir = /tmp/smokeping-ms/var
piddir = /usr/local/smokeping/var
cgiurl = http://some.url/smokeping.cgi
cgiurl = http://本机IP/htdocs/smokeping.cgi;
smokemail = /home/oetiker/checkouts/smokeping/trunk/software/etc/smokemail.dist
smokemail = /usr/local/smokeping/etc/smokemail
tmail = /home/oetiker/checkouts/smokeping/trunk/software/etc/tmail.dist
tmail = /usr/local/smokeping/etc/tmail.dist
*** Presentation ***
template= /home/oetiker/checkouts/smokeping/trunk/software/etc/basepage.html.dist
template = /usr/local/smokeping/etc/basepage.html
*** Probes ***
+ FPing
binary = /usr/sbin/fping
binary = /usr/local/sbin/fping
#** Database ***
step = 60
pings = 10

修改ping的频率，默认为300秒ping20 次，我们可以根据需要调整，这里修改为60秒 ping 10次。
*** Targets ***
#=================================
#这里用于配置监控目标，以+号分层,+为首页，++为子层，我们以百度和搜狐为例。
+TEST             
menu= TEST
title = TEST
++ baidu        
menu = baidu
title = baidu
host = 115.239.210.27
++ sohu
menu = sohu
title = sohu
host = 121.14.0.97
#=================================
3. 添加目录

建立下面三个目录用于保存smokeping的数据等

mkdir /usr/local/smokeping/data

mkdir /usr/local/smokeping/var

mkdir /usr/local/smokeping/htdocs/cache

chown –R apache:apache /usr/local/smokeping

4. 修改apache配置文件

vi /etc/httpd/conf/httpd.conf
添加下面内容：
Alias /smokeping/ "/usr/local/smokeping/htdocs/"
Alias /cache/ "/usr/local/smokeping/cache/"
<Directory "/usr/local/smokeping/htdocs">
Options FollowSymLinks ExecCGI
AllowOverride None
AddHandler cgi-script cgi
Order allow,deny
Allow from all
</Directory>

三．启动
1.重启apache
service httpd restart

2.重启smokeping
/usr/local/smokeping/bin/smokeping restart

完成。
