Apache + 20 virtual hosts + awstats?

Apache + 20+ virtual hosts + awstats with one access log?

Can one configure awstats to properly render individual awstats pages per virtual host if all virtual hosts are writing to the same access log?

Yup. You need an separate config files for each domain, named, and set the SiteDomain= and HostAliases= and DirData= config entries as suited. Then run awstats.pl -update -config=filename for each host. I do that automatically in apache logrotate, just before the log is rotated out.

benzo: Is there anything you'd need to do the LogFormat of the access log so that it includes virtual host information?

I believe the logging token is %V.

I use:

LogFormat "%v %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" vhost
CustomLog /var/log/apache/access.log vhost

On preview: Yes, it's the %v that's important.

I'm assuming it's better for Apache to dump all access information into one log vs. N number of virtual host specific access logs. Anyone have thoughts?

I run a LogFormat like benzo8's and then pipe the output into vlogger which automatically sorts the log lines into separate files without my having to separately configure the virtual hosts, and rotates them by date in the bargain. Here's my configuration:

LogFormat "%v %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" vlogger
CustomLog "| /usr/local/bin/vlogger -u httpd -g httpd -s access_log -t access_log.%Y%m%d /web/logs" vlogger

Thanks. One last question- I assume the LogFormat line in the awstats conf files must match the Apache line verbatim?

Here's the LogFormat directive I use in the awstats configuration files:

LogFormat="%virtualname %host %logname %other %time1 %methodurl %code %bytesd %refererquot %uaquot"

Basically - yup - awstats needs to know what each field in the access.log represents.

Do you guys separate SSL access logs?

Indeed - it's basically a different server, so it gets different logs and different configuration.

Thanks bezno8- appreciate it.

I've never encountered Apache being bound by its logging. Lots of other things, but not logging. I would be extremely surprised if having a log per vhost would have any noticeable impact on performance.

Most setups I have seen have one log per vhost. Certainly tidier.

Google Analytics?

If the question is about awstats, Google Analytics are not the answer, especially since they'll miss everybody with the NoScript extension.
