這篇文章主要介紹增加 cacti 監(jiān)控對象時導致數據庫出問題怎么辦，文中介紹的非常詳細，具有一定的參考價值，感興趣的小伙伴們一定要看完！
生產環(huán)境：
數據庫：mysql 5.5.49-cll-lve
問題：在眾多 Cacti 監(jiān)控的對象中，由于增加了監(jiān)控對象 nginx，導致 cacti 在監(jiān)控所有對象中僅有 1 個對象出圖出數據。
分析：
1.systemutilities – Rebuild poller cache #需要重建 cache 嗎？
2. 系統時間不準確，重新設置時間 # 需要更新服務器時間嗎？
3. 圖像沒有生成，運行
# /usr/bin/php /var/www/html/cacti/poller.php –force #出現數據了嗎？
4. 權限問題，修改權限 #chmod 777 -R /var/www/html/cacti/rra #沒有權限嗎？
5.crontab -e # 定時任務的問題嗎？
6. 數據庫表有損壞。# 需要修復數據庫嗎？
出現問題之后，我們要通過檢查錯誤日志來分析問題所在，請查看附件。
通過查看 cacti 日志文件，發(fā)現沒有加載有效數據，通過修復 cacti 數據庫解決了出圖出數據的問題。
