About
These graphs depict the amount of traffic over time to various ports on our public network interface.
The short period graphs are more accurate because traffic is sampled at higher rates than graphs for
longer time spans. The Who's Online graph merges information from the entire site via embedded chatter, our forum, and the IRC server, but not unique visitors to /wiki, /media or /meme yet.
Here's the sample rate for each graphed timespan:
| Graph Duration | Sample Rate |
* 1year graphs only sample traffic once a day so accuracy is doubtful, yet they do reflect annual trends like less overall traffic during summer in the
northern hemisphere.

The architecture of this system is based upon the tutorial Monitoring network traffic with iptraf and rrdtool and related docs.
