操作系统：CentOS release 6.8 (Final)

数据库：MySQL 5.5.49-cll-lve

问题：在众多Cacti监控的对象中，由于增加一台服务器增加了一个了监控对象Windows系统，导致cacti在监控所有对象中仅有1个对象出图出数据。

分析：

1.图像没有生成，运行# /usr/bin/php /var/www/html/cacti/poller.php --force #出现数据了吗？
2.权限问题，修改权限#chmod 777 -R /var/www/html/cacti/rra  #没有权限吗？
3.数据库表有损坏。#需要修复数据库吗？

4.重新启动snmp服务。

5.使用snmpwalk 获取各种信息。

   出现问题之后，我们要通过检查错误日志来分析问题所在。

    此次增加cacti对象导致两个问题，一个是导致数据库发生错误，另一个是snmp运行服务的问题。
