[syslog-ng] Forwarding flat files to a remote syslog-ng server

[Song, Young]

Hi Balázs,


In fact, I’m trying to forward the following 3 different types of logs:



  1.  Audit logs (from auditd on Solaris 10 using the “audit” facility) --> syslog-ng server cannot recognize “audit” facility, though, and thus not working



  1.  OS logs (from syslog facilities) --> Using various facilities and levels


  1.  Oracle logs (flat file) --> Using the “local1” facility, as in my first email, but not working


How to separate them so that each logs get stored in different locations is my challenge.


Thanks.

Hi,


Couple of notes:

* When reading messages from a file, you are using flags(no-parse) which means that you will not have facility information. I dont see that you need the filter at all, as you are using dedicated destinations. I think that filter can be removed.
* you dont need separate destinations to each file, just use one destination and connect both sources to it
* If you run syslog-ng in foreground and enable debug mode it emits information about messages entering and leaving
* 3.6 is ancient, not to mention 2.0.9, you should probably upgrade

Hi,


I’m trying to send various flat files to a central syslog-ng server.

So, I have the following setups but somehow using the “local1” and “local2” facilities don’t work, although no errors when restarting syslog services on both client & server.

Any advice would be appreciated much!


=======================================================================

My syslog-ng CLIENT (running syslog-ng 3.6.2):

source s_file1 { file("/var/log/syslog/file1.log" follow-freq(1) flags(no-parse) program_override("audit")); };
filter f_file1 { facility(local1); };
destination d_file1 { syslog("10.10.10.10" transport("udp") port(514)); };
log { source(s_file1); filter(f_file1); destination(d_file1); };

source s_file2 { file("/var/log/syslog/file2.log" follow-freq(1) flags(no-parse) program_override("audit")); };
filter f_file2 { facility(local2); };
destination d_file2 { syslog("10.10.10.10" transport("udp") port(514)); };
log { source(s_file2); filter(f_file2); destination(d_file2); };


========================================================================

My syslog-ng SERVER (10.10.10.10 – running syslog-ng 2.0.9):

destination d_file1 { file ("/var/log/syslogs/file1-$YEAR$MONTH$DAY.log" owner(root) group(root) perm(0644) dir_perm(0755) create_dirs(yes)); };
filter f_file1 { facility(local1); };
log { source(remote); filter(f_file1); destination(d_file1); };

destination d_file2 { file ("/var/log/syslogs/file2-$YEAR$MONTH$DAY.log" owner(root) group(root) perm(0644) dir_perm(0755) create_dirs(yes)); };
filter f_file2 { facility(local2); };
log { source(remote); filter(f_file2); destination(d_file2); };


Thanks.
