spine是一个基于C语言的，非常快速的轮询引擎。使用 spine 比 使用 cmd.php 效率高，特别是在当 cmd.php 执行接近或超过 300 秒的时候。cmd.php采集存在大的延迟，从添加设备到up，spine通常不到一分钟，而cmd.php等的时间较长，超过10分钟。当设备down后 2分钟之内spine可以发出alert，而cmd.php可能需要10分钟以上。 yum install cacti-spine -y 配置 chmod +r /etc/spine.conf vim /etc/spine.conf 创建一个软链接文件(因为spine默认会去读取该sock文件) ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock 验证spine是否正常 /bin/spine 用管理员帐号登陆Cacti.在系统参数中制定Spine/Cactid的物理路径.
