【移动应用开发技术】监控cactinagioszabbix(一)cacti

cacti重图形，有数据历史，需用到数据库支持，支持web配置，默认不支持告警，可以加插件；nagios重状态和结果，没有数据历史，不成图像，不支持web配置，可以自己开发脚本定制个性化监控，支持多种插件；zabbix有数据历史，可成图像，支持web配置，可以自动发现；第一部分：监控软件Cacti搭建一、环境准备

1、安装epel扩展源

关闭selinux

临时关闭setenforce0

vim/etc/selinux/config

SELINUX=disbabled1[root@cacti

~]#

yum

install

-y

epel-release

2、搭建lamp环境12345678910111213141516171819202122232425262728293031323334353637[root@cacti

如果访问不了，请检查主机的iptables和selinuxhttp://IP/cacti/

点两下“next”和一次”Finish“即可输入admin

admin登录，重新设置新的密码5查看默认主机执行poller.php,生成图形，加入计划任务/usr/bin/php/usr/share/cacti/poller.php添加cron任务cront-e

增加：*/5****

/usr/bin/php/usr/share/cacti/poller.php6添加需要被监控的主机接下来我们添加被监控的主机在被监控的主机上安装修改syslocation以及syscontact,其中syslocation可以写本机ip，syscontact写管理员邮箱view

systemview

included

..2.1.1修改为:view

systemview

included

..2.1（如果不改，可能找不到网卡）7启动snmp

/etc/init.d/snmpdstart8管理cacti后台点console,再点Device，在右上角点”Add“

Description

写本机ip或你自定义一个名字Hostname

写本机ipHostTemplate

选ucd/net

SNMPHostSNMPVersion

选Version2点右下角的create点右上角的”CreateGraphsforthisHost“GraphTypes:

选择SNMP-InterfaceStatisticsGraphTypes:

再选择GraphTemplateBased在下面的框中，选择你要监控的项目，比如ucd/net-LoadAverage在右侧小方块中打对勾，然后点右下角的create9添加实时监控后台选中”DefaultTree“点右上角的AddTreeItemType选择”Host“Host选择我们刚刚增加的那个机器ip点右下角的create10点左上角的Graphs在左侧可以看到DefautTree下面已经增加了我们刚刚添加的主机，图形一开始不会那么快出来，要等一小会才可以。参考文章：/admin/html/201310/1956.html

Cacti安装高效轮询器spine(转)Cacti默认轮询器cmd.php执行效率有点低，spine为C语言编写的组件，性能要好许多。编译安装spine需以下软件支持：1net-snmp-devel2mysql3mysql-devel4openssl-devel5gcc安装spine要和Cacti的版本相匹配，本文以最新版cacti0.8.8a安装为例。1cd/usr/local/src/2wget

/downloads/spine/cacti-spine-0.8.8a.tar.gz3tar-zxvfcacti-spine-0.8.8a.tar.gz4cdcacti-spine-0.8.8a
