Cacti 图表不出来,报Maximum runtime错误

图表一直正常,但突然就不出图,查看cacti日志,如下:

解决方案:

解决步骤1：
使用cactiuser用户手动执行poller.php，将错误重定向到一个文件中

#su cactiuser
#/usr/local/bin/php /var/www/html/cacti07/poller.php > ./error.log 2>&1 (查看是否有错误信息)

解决步骤2：

修改cacti setting的poller设置.

settting-->poller:

Maximum Concurrent Poller Processes 把1改成4

Maximum Threads per Process         把1改成2

Number of PHP Script Servers        把1改成6
