I deleted all my old server logs today. Roughly 2 years worth of information about all those who requested information from my web server. Sure, half (or more) was unintelligible Nimda and Code Red crap, but there was a sizable amount of legitimate stuff as well. I’d say I averaged 1.5 GigaBytes of data transferred per month over the last year, and around 1GB/mo before that.
So why did I ditch it? To make room? Well, yes, sort of. The logs were quite large, but not unwieldy. I just finished setting up analog to monitor all three virtual hosts now being served, and I wanted a clean run. No errors from old log formats, etc… Wipe the slate clean.
