linux下构建Smokeping网络监控平台
一. Smokeping 简介
1.1 Smokeping简介：
Smokeping 是rrdtool 的作者Tobi Oetiker 的作品，是用Perl 写的，主要是监视网络性能，包括常规的ping，用echoping监控www 服务器性能，监视dns 查询性能，监视ssh 性能等。底层也是rrdtool做支持，特点是画的图非常漂亮，网络丢包和延迟用颜色和阴影来表示。
1.2 Smokeping 架构组件
Smokeping 有以下组件组成：RRDtool、Fping、Echoping、Curl、Dig、SSh、Perl 模块，Perl、SpeedyCGI、Apache 等。
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．Smokeping 安装
[root@smokeping ~]# uname -a
Linux smokeping.junjie.com 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:54 EDT 2009 i686 i686 i386 GNU/Linux
[root@smokeping ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.4 (Tikanga)
[root@smokeping ~]# perl -v
This is perl, v5.8.8 built for i386-linux-thread-multi
先暂时关闭iptables以及selinux刨除其他影响
构建本地yum数据库
[root@smokeping ~]# cat /etc/yum.repos.d/server.repo
name=Red Hat Enterprise Linux server
name=Red Hat Enterprise Linux vt
name=Red Hat Enterprise Linux cluster
name=Red Hat Enterprise Linux clusterstorage
[root@smokeping ~]#
[root@smokeping ~]# mkdir /mnt/cdrom
[root@smokeping ~]# mount /dev/cdrom /mnt/cdrom/
mount: block device /dev/cdrom is write-protected, mounting read-only
[root@smokeping ~]# yum list all
RRDTool 是由Tobias Oetiker 开发的开源软件，它使用RRD（Round Rebin Databases）作为存储格式，Round robin 是一种处理定量数据以及当前元素指针的技术，RRDTool 主要用来跟踪对象的变化情况，生成改对象变化的趋势图。
[root@smokeping ~]# cd /root/smokeping/
[root@smokeping smokeping]# ls
cgilib-0.5.tar.gz
# 安装依赖的软件包:
[root@smokeping smokeping]# yum -y install freetype freetype-devel libpng libpng-devel gd gd-devel libxml2 libxml2-devel libiconv libiconv-devel pango pango-devel qpixman qpixman-devel glib glib-devel cairo cairo-devel libart* gettext gettext-devel libjpeg libjpeg-devel perl-XML-Simple.noarch perl-Crypt-SSLeay perl-Digest-HMAC
使rrdtool支持中文
[root@smokeping smokeping]# cat /etc/sysconfig/i18n
[root@smokeping smokeping]# export LANG="zh_CN.UTF-8"
[root@smokeping smokeping]# yum -y install fonts-chinese
[root@smokeping smokeping]# tar -zxvf rrdtool-1.4.4.tar.gz -C /usr/local/src/

在smokeping的子目录中会发现很多“*.dist”命名的文件，这些文件使用的时候请将其改名为“*”并进行配置
[root@smokeping ~]# cd /usr/local/smokeping/
[root@smokeping smokeping]# ls
[root@smokeping smokeping]# cp -a htdocs/smokeping.cgi.dist htdocs/smokeping.cgi
[root@smokeping smokeping]# cp -a etc/config.dist etc/config
接着建立三个目录用于保存smokeping的数据等，如下所示：
[root@smokeping ~]# mkdir /usr/local/smokeping/data
[root@smokeping ~]# mkdir /usr/local/smokeping/var
[root@smokeping ~]# mkdir /usr/local/smokeping/cache
[root@smokeping ~]# chown -R apache.apache /usr/local/smokeping
mailhost = my.mail.host
sendmail = /usr/lib/sendmail
imgcache = /usr/local/smokeping/cache
cgiurl = http://192.168.101.81/smokeping/smokeping.cgismokemail = /usr/local/smokeping/etc/smokemail.dist
tmail = /usr/local/smokeping/etc/tmail.dist
*** Presentation ***
template = /usr/local/smokeping/etc/basepage.html.dist
binary = /usr/sbin/fping##修改为实际路径
binary = /usr/local/sbin/fping
把#*** Slaves ***下的所有东西注释掉，这里暂时不采用master/slave模式。
在Targets下添加监控节点，其中Multi也就是在一张图里画多个监测点的数值：
title = 21ViaNet(China)Telecom
menu = xjzhujunjie
title = xjzhujunjie-server
host = 192.168.101.82

（3）someloss 表示30个包丢1个，连续出现3次就发送报警；rttbad表示连续两个包延迟超过50ms就发送报警。
其它关于smokeping的使用，待续…….
