neophyte webserver statistics question

[tvaniderstine]

Under View Server xxxx statistics, my server shows 3.562 (and I don't know if that is less than 4 or more than three thousand) messages sent yesterday. When I look at /var/log/zimbra.log.?, I see that 11 messages were sent yesterday.

Can someone help me understand what I'm seeing or point me to a valid url where these statistics are described? Also, is that number a decimal or an integer? If it's a decimal, where did the fractional message come from (or go)? If it's and integer, is there a way to replace the "." with a "," for my own clarity?

I'm running ZCS 7.1 on CentOS 5.5.

Thanks.
