本文主要介绍在添加cacti监控对象时如何处理数据库问题。很详细，有一定的参考价值。感兴趣的朋友一定要看完！
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.系统实用程序重建轮询器缓存#您需要重建缓存吗？
2.系统时间不准确。重置时间#是否需要更新服务器时间？
3.图像没有生成和运行。
#/usr/bin/PHP/var/www/html/cacti/poller . PHP-force #有数据吗？
4.允许。修改权限# chmod 777-r/var/www/html/cacti/rra #是否没有权限？
5.crontab -e #计划任务的问题？
6.数据库表已损坏。#需要修复数据库吗？
出现问题后，我们需要查看错误日志来分析问题。请看附件。
通过查看cacti日志文件，发现没有加载有效数据，通过修复cacti数据库解决了数据出图问题。
