#一开始无图，然后处理后有无数据，后面开始查资料：
cacti无图像或者无数据，网上查到的检查
1.system utilities –>Rebuild poller cache
2.系统时间不准确，重新设置时间
3.图像没有生成，运行#/usr/bin/php /srv/www/htdocs/cacti/poller.php –force
4.权限问题，修改权限#chmod 777 -R /srv/www/htdocs/cacti/rra
5.数据库表有损坏，修复#mysqlcheck -ao cacti –auto-repair -uroot -p
6.重启snmpd服务#service snmpd restart
