A single syslog service can receive and process messages from multiple applications on multiple devices.
syslog messages have a concept of message type or message class known as facility. All messages are "stamped" with a facility.
There are eight facilities available to group and process messages as you wish. These are named local0 - local7.
FWSM messages are sent as local4 by default. This can be changed with the "logging facility" command.
Depending on the capabilites of the syslog program receiving the messages you should be able to
configure it so messages arriving with a certain facility are processed in a customised way.
For example, collect only local4 messages into a file named "fwsm.log"
If this does not meet your needs and you _REALLY_ do require a second syslog service
then FWSM can be configured to send syslogs to a non-standard port with optional udp (or tcp) parameters
on the "logging host" command. For example, you configure a second instance of syslog receiver on your
server IP address 1.1.1.2 listening on udp port 60000 the FWSM config would be
"logging host INSIDE 1.1.1.2 udp/60000"
