我的CACTI－－FAQ

lues

我在实际中还碰到2个问题
1.对远程服务器执行/usr/bin/php /var/www/html/cacti/poller.php命令时有出现Timeout问题,但是并不时每次超作都超时，而且在同一次定时任务中，对同一台机器的操作有的操作超时，有的操作不超时
OK u:0.00 s:0.01 r:1.02
OK u:0.00 s:0.01 r:1.02
Timeout: No Response from xxx.xxx.xxx.xxx:161.
Timeout: No Response from xxx.xxx.xxx.xxx:161.

2.周、年统计图字母乱码

1、可能是网络问题。snmp使用udp协议，容易丢包，如carrison所说， 把snmp的timeout时间设长一点试试，或多开几个进程。



2、乱码是因为这张图太挤了，英文太多，所以显示不出来。试一下升级rrdtool到1.2 ...

1.我已经把settings->general->SNMP Timeout的值设为5000了,settings->general中的Maximum Concurrent Poller Processes和Maximum Threads per Process两个值都设为5了,但是还是有Timeout: No Response from xxx.xxx.xxx.xxx的问题，而且可以肯定网络一直是通的

2.我的rrdtool已经是1.2.11了，有没有办法把图搞大呢，我把graphs->settings->Thumbnail Width的值改为了400也没用

今天又发现我的cacti的图像出现断层的问题，开始以为是Timeout的问题，但是出现问题的机器是局域网的而且连的是同一个交换机，于是察看日志，发现日志一切正常，/usr/bin/php /var/www/html/cacti/poller.php命令没有出现Timeout的情况，为什么我的cacti的图形还出现断层的情况呢？
