Per-port monitor configuration scripts (/etc/saf/pmtag/_config) are optional. They enable you to customize the environment for any given port monitor and for the services that are available through the ports for which that port monitor is responsible. Per-port monitor configuration scripts are written in the same language that is used for per-system configuration scripts.
The per-port monitor configuration script is interpreted when the port monitor is started. The port monitor is started by the SAC after the SAC has itself been started and after it has run its own configuration script, /etc/saf/_sysconfig.
The per-port monitor configuration script might override defaults provided by the per-system configuration script.
