[syslog-ng] configuring different sources on the syslog-ng server

Hi,
Perhaps I am wrong (so please correct me), but I assume you want to do
the following:
all of your clients read logs from two source (weblogic, apache) and
send them to syslog-ng server via tcp.
You would like to store these logs different place on syslog-ng server,
one for weblogic logs and other one for apache logs. Is it true?
If it is, you have a lot of possibility to do that.
e.g.:
1, You can set different port numbers (but the same ip) for two
destinations in client config, and set two sources on server side with
these ports
example:
client side (as you wrote):
destination apacheaccesslog {
tcp("192.x.x.x " port(3331));
};
destination weblogiclog {
tcp("192.x.x.x " port(3332));
};
server side:
source apacheacceslog{tcp(port(3331));};
source weblogiclog{tcp(port(3332));};
After that you can use these sources in different log paths
2,
You can use only one tcp destination in client configuration, in this
case you need to split the logs with filters using program name or other
entity (you can override value of $PROGRAM macro with program_override()
option) on server side
Also you may not know but you can also use macros in file path.
