netmon@gentoo.org Gentoo network monitoring and analysis project Spine (formerly known as Cactid) is a poller for Cacti that primarily strives to be as fast as possible. For this reason it is written in native C, makes use of POSIX threads, and is linked directly against the net-snmp library for minmumal SNMP polling overhead. Spine is a replacement for the default cmd.php poller so you must decide if using Spine makes sense for your installation.
