Bertha 。 2022-08-14 00:54 219阅读 0赞

Cacti 在英文中的意思是仙人掌的意思，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，使用PHP开发，它是由一些PHP页面组成软件，主要针对企业的大量网络设备、服务器主机\*\*\*能监测服务，可提供对CPU负载、内存占用、运行进程数、磁盘空间、网卡流量等各种数据信息的监测，cacti注重的是状态监控，报警和服务恢复功能比较差。

定义监控哪些设备：

控制面版-->建立设备-->定义设备-->为设备生成图像-->在图像树中添加新设备

console-->Devices-->add(左上角)-->define devices-->Create Graphs for this Host-->create

在被监控客户机上要安装net-snmp,41行那里要填写监控端的IP地址。

\[root@rhel64 ~\]\# yum -y install net-snmp

\[root@rhel64 ~\]\# vim /etc/snmp/snmpd.conf

62 access  notConfigGroup ""      any       noauth    exact  all none none
