貌似是nginx没有加载rrdtool模块的原因，手动执行poller.php之后在rra目录下仍然没有rrd文件

请问这可能是什么原因，个人觉得是是nginx没有加载rrdtool模块，如果是这样的话，怎样让nginx加载rrdtool？
谢谢。
那个报错信息是php里面没有设置date.timezone造成的,应该不是问题的主要原因
你进入cacti的页面,看看cacti的配置 本帖最后由 陌生丶 于 2013-07-03 15:05 编辑
你的报错是时区的问题,提示修改时区为Asia/Singapore（新加坡）
修改下php.ini,找到date.timezone,修改成date.timezone=Asia/Singapore,重启apache 回复 4# chenyx
但是执行这个脚本之后rra目录仍然是空的，没有任何rrd文件
进入cacti的页面？是我自己搭建的监控页面，还是cacti的官方页面？
不好意思，小弟菜鸟初学，对这个问题没什么思路，请指点一下，谢谢。
就是你自己的linux,用web访问,进入后再左面有console,找到setting,进去看下吧 回复 7# chenyx
没有什么跟这个问题有关系的设置啊
进入console->setting,里面有个paths卡,在里面有设置rrdtools的地方啊
