Events and Timers
There are a number of elements of a Pathfinder Core PRO system that should only execute on a single system at
a time so that a cluster is not requesting duplicate changes from a device. Examples of this are Logic Flows and
Timers. Those will always execute on the system that is currently active and has the lowest IP address. Heartbeats
are constantly sent and monitored between the systems so that if a system stops responding the next lowest IP
address system will take over those responsibilities.
Clustering and SapV2
SapV2 is the protocol that is used both for cluster communications and for internal communications. This protocol
is available on port 9600 and is described in more detail in the appendix of this manual. If the cluster does not seem
to be working properly there is a great deal of information that can be collected about the clustering process using
this protocol to try and solve the problem.
