luxinjun

大家好，我系统CENTOS 5.5 CACTI版本0.8.7e rrdtool版本1.2.27 php5.2.14 apache2.2.15
，在刚安装完成后，添加设备监控都正常。但是第二天，再次添加设备中，CPU,内存磁盘都正常，但是在添加网卡流量监控这里点create后页面出现如下错误：
Notice: Undefined index: local_data_id in /usr/local/apache/htdocs/cacti/graphs_new.php on line 214

Warning: Invalid argument supplied for foreach() in /usr/local/apache/htdocs/cacti/graphs_new.php on line 214

Warning: Cannot modify header information - headers already sent by (output started at /usr/local/apache/htdocs/cacti/graphs_new.php:214) in /usr/local/apache/htdocs/cacti/graphs_new.php on line 330

网卡添加监控出现问题，而CACTI.LOG日志没有任何显示，不知道大家有没有碰到这个情况，是否有解决办法，谢谢了！
