TX bytes vs. httpd bytes
I'm getting a consistent disparity between the total bytes sent by Apache vs. the number of tx bytes reported by ifconfig. On one instance, httpd logs summed 1.7 GB delivered, while ifconfig tx bytes showed an increase of only 371MB. I realize the tx byte counters are 32-bits and wrap frequently but checking again on other days it's no different.
Compression by apache is also not the case. Also, adding just the 200 codes alone (certain deliveries) also add up to far more than what ifconfig reports. Taking snapshots of /proc/net/dev show the same as ifconfig. Any insight appreciated.
Oh, some info: CentOS 4.1, httpd 2.0.52, all traffic on eth0, nothing unusual.
