Webalizer and apache log

Hi!

Well how often do you run webalizer ?
When does webalizer run ?

I ran webalizer every hour.
I rotated logs once every week, keeping 4 weeks.

This gave us very good accuracy, I never experienced that we lost any info.
Let's say webalizer runs 0:00 at night, every hour.
The logrotate runs at the same time, but it's not only apache logs that needs rotating.
Webalizer only has to parse one hour of traffic.
It will most likely be done by the time logrotate comes to apache.

If you are really, really unlucky, you might loose 45-60 minutes of traffic between 23:0x and 24:0x.

But my experience is that I at most lost 1-3 minutes if any at all.
Thoose minutes are between 24:00-24:03

I came up with this solution:

* I edited "httpd" logrotate configuration in /etc/logrotate.d to be like this :

/home/www/mydomain.com/logs/*log {
    missingok
    notifempty
    sharedscripts
    prerotate
        /usr/bin/webalizer
    endscript
    postrotate
        /bin/kill -HUP `cat /var/run/httpd.pid 2>/dev/null` 2> /dev/null || true
    endscript
}

* I set webalizer.conf to do incremental and the log file to be processed is :

   /home/www/mydomain.com/logs/apache.log

* I removed 00Webalizer from /etc/cron.daily , because webalizer will be executed by logrotate process.

My scenario is : When the logrotate process occured, it will run webalizer and then rotate the log.

Is this a good solution? Or is it wrong?

I am not an experience linux admin btw.

Please if you can verify my solution :)

Thank you
