生产环境：

数据库：MySQL 5.5.49-cll-lve

问题：在众多Cacti监控的对象中，由于增加了监控对象nginx，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.systemutilities –>Rebuild poller cache #需要重建cache吗？
2.系统时间不准确，重新设置时间  #需要更新服务器时间吗？
3.图像没有生成，运行

# /usr/bin/php /var/www/html/cacti/poller.php --force #出现数据了吗？
4.权限问题，修改权限#chmod 777 -R /var/www/html/cacti/rra #没有权限吗？
5.crontab -e  #定时任务的问题吗？

6.数据库表有损坏。#需要修复数据库吗？

 出现问题之后，我们要通过检查错误日志来分析问题所在，请查看附件。

通过查看cacti日志文件，发现没有加载有效数据，通过修复cacti数据库解决了出图出数据的问题。
