介绍
Cacti是一套基于PHP,MySQL,SNMP及RRDTool开发的网络流量监测图形分析工具。Cacti是通过 snmpget来获取数据，使用 RRDtool绘画图形。它提供了非常强大的数据和用户管理功能，可以指定每一个用户能查看树状结构、host以及任何一张图，还可以与LDAP结合进行用户验证，同时也能自己增加模板，功能非常强大完善。界面友好。软件 Cacti 的发展是基于让 RRDTool 使用者更方便使用该软件，除了基本的 Snmp 流量跟系统资讯监控外，Cacti 也可外挂 Scripts 及加上 Templates 来作出各式各样的监控图。
snmp关系着数据的收集，rrdtool关系着数据存储和图表的生成，snmp抓到数据不是存储在mysql中，而是存在rrdtool生成的rrd文件中（在cacti根目录的rra文件夹下）。rrdtool对数据的更新和存储就是对rrd文件的处理，rrd文件是大小固定的档案文件（Round Robin Archive），它能够存储的数据笔数在创建时就已经定义
准备工作
http://www.cacti.net/download_cacti.php http://www.cacti.net/downloads/cacti-0.8.8b.tar.gz http://www.cacti.net/downloads/spine/cacti-spine-0.8.8b.tar.gz
安装rrdtool
getconf LONG_BIT rpm -ivh http://apt.sw.be/redhat/el6/en/i386/rpmforge/RPMS/rpmforge-release-0.5.2-2.el6.rf.i686.rpm rpm -ivh http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm yum install rrdtool -y
安装配置snmp
yum install net-snmp net-snmp-libs net-snmp-utils -y chkconfig snmpd on
snmp配置文件 /etc/snmp/snmpd.conf
com2sec notConfigUser 127.0.0.1 public group notConfigGroup v1 notConfigUser group notConfigGroup v2c notConfigUser view systemview included .1.3.6.1.2.1 view systemview included .1.3.6.1.2.1.25.1.1 access notConfigGroup "" any noauth exact all none none view all included .1 80 syslocation Unknown (edit /etc/snmp/snmpd.conf) syscontact Root <root@localhost> (configure /etc/snmp/snmp.local.conf) dontLogTCPWrappersConnects yes
启动然后测试
service snmpd start snmpwalk -v 1 -c public localhost .1.3.6.1.2.1.1.1.0 snmpwalk -c public -v 2c 127.0.0.1 system
输出类一下信息则表明安装成功
