We have a live help on our server that generates an insane amount of access logs as you can imagine. Currently they're appended to all of the other access logs for the site they run on. This makes it difficult to sort through the error logs. Is there a way I can specify that anything within /livehelp go into a different log file?
If you move /livehelp to its own VirtualHost (which requires its own HostName) you can customize the logs to keep them separate. You would use the CustomLog and ErrorLog directives to specify the location for those logs.
<VirtualHost *:80> ServerName livehelp.example.com DocumentRoot /path/to/the/livehelp/folder ErrorLog logs/livehelp-error_log CustomLog logs/livehelp-access_log combined </VirtualHost>
You could use the piped log  feature of apache. Create a shell script like
#!/bin/sh PATTERN="/livehelp" FLAGS="-v" if [ "x$1" == "xlive" ]; then FLAGS="" fi; grep $FLAGS "$PATTERN" > $2
(untested and needs improvement)
CustomLog "|/path/to/script live /var/log/live" combined
CustomLog "|/path/to/script std /var/log/std" combined
to the apache config
you can add some more filtering here if you need
