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.
