[syslog-ng] Before the basic 101 questions

Tue Jul 21 09:44:27 CEST 2009

Lance,

Depending on how you want to process the collected logfiles, you can also
configure Apache:

ErrorLog syslog:local1
CustomLog "|/usr/bin/logger -t apache -i -p local6.notice" combined

This can be done global (for all virtual hosts) or per virtual host. How to
add the name of the virtual host to the messages in the access logs can be
found here: http://httpd.apache.org/docs/2.0/logs.html

All that remains to be done is to forward syslog from the client with the
webservers to the syslog-ng server.

regards,

Siem Korteweg

Joe, thanks for the update.    Yes, that is the directory name.  Now
regarding the "file", I will start a little more reading, but I don't think
I would have to do this for each file right?  This server (along with the
others in the cluster) have 12 or so virtual sites, each with it's own
access and error log, so that would be at least 24 'file' sources.  Is there
a way to wildcard it?

Also, (I know this too is a basic Q) but are these defined on the
server/client or both?  I still don't see how they mesh, but soon, oh soon
when that light comes on!

Thanks
