生產(chǎn)環(huán)境：

在鼎城等地區(qū)，都構(gòu)建了全面的區(qū)域性戰(zhàn)略布局，加強(qiáng)發(fā)展的系統(tǒng)性、市場前瞻性、產(chǎn)品創(chuàng)新能力，以專注、極致的服務(wù)理念，為客戶提供成都網(wǎng)站建設(shè)、成都網(wǎng)站制作 網(wǎng)站設(shè)計制作按需制作網(wǎng)站,公司網(wǎng)站建設(shè),企業(yè)網(wǎng)站建設(shè),品牌網(wǎng)站設(shè)計,成都營銷網(wǎng)站建設(shè),成都外貿(mào)網(wǎng)站建設(shè)公司,鼎城網(wǎng)站建設(shè)費(fèi)用合理。

操作系統(tǒng)：CentOS release 6.8 (Final)

數(shù)據(jù)庫：mysql 5.5.49-cll-lve

問題：在眾多Cacti監(jiān)控的對象中，由于增加一臺服務(wù)器增加了一個了監(jiān)控對象Windows系統(tǒng)，導(dǎo)致cacti在監(jiān)控所有對象中僅有1個對象出圖出數(shù)據(jù)。

分析：

1.圖像沒有生成，運(yùn)行# /usr/bin/php /var/www/html/cacti/poller.php --force #出現(xiàn)數(shù)據(jù)了嗎？
2.權(quán)限問題，修改權(quán)限#chmod 777 -R /var/www/html/cacti/rra #沒有權(quán)限嗎？
3.數(shù)據(jù)庫表有損壞。#需要修復(fù)數(shù)據(jù)庫嗎？

4.重新啟動snmp服務(wù)。

5.使用snmpwalk 獲取各種信息。

   出現(xiàn)問題之后，我們要通過檢查錯誤日志來分析問題所在。
