Cacti配置流程 Cacti是一个简单直观的监控工具,后台使用rrdtool记录监控数据,虽然功能较少,但是图形显示效果比较好看、直观、配置也比较方便,当需要有复杂的监控需求时,可以使用zabbix或者nagios来做。 这里主要讲的是Cacti两方面的配置,一个是添加设备,另外一个是配置权限 添加监控设备 首先需要在被监控的设备上安装与配置snmp agent,Linux平台请参考Linux安装与配置Snmpd,OpenSolaris参考OpenSolaris net-snmp install script,windows安装配置snmp agent方法 检查是否存在SNMP Service,需要将此服务启动。我的电脑-管理-服务-SNMP Ssrvice. 单击属性-安全,添加发送身份验证陷阱。添加在cacti中的SNMP Community,在下面添加监控端的IP地址 如果没有此服务,通过控制面板-添加组件-管理和监视工具-简单网络管理协议。 添加设备 登陆Cacti后点击面板左侧的devices后点击右侧面板的Add,之后填写Description, Hostname, Host Template(Linux与Solaris使用ucd/net SNMP Host,Windows使用windows2000/xp Host), 其他部分可以使用自己的值来填写"SNMP Community"或者保持不变。配置完成后点击Create增加此设备。 在创建完毕后出现的页面中点下Query Verbose 来测试下snmp数据抓取是否正常。 添加图像 点击页面中的"Create Graphs for this Host" 选中所有复选框后点击"Create",完成生成图像的设置 设置图像数 点击面板左侧的"Graph Trees" –> "Add",输入name后"Create" –> "Save" 把设备添加到心的图像树中 在"Devices"中选中刚加入的设备选择 "Place on a Tree" –> "Go" –> "Continue",到这里设备的配置已经完成,可以点击导航栏的graphs查看新增加设备的各种监控图像,下面是我Cacti监控数据的两个截图 权限配置 增加新用户 […]
