Syslog capturing

Hi,

I have 10 AIX machines connected to one linux machine(server) to
collect all the syslog messages (its working). I want to organise in
such a way different logs from diferent machines should go into one
file. example *.error messages from all the 10 AIX machines should go
into one file dedicated only for *.error messages. Do any one knows how
to seperate the messages from remote machines.

Thanks

.
