Do we process squid logs?On Mon, Aug 26, 2013 at 3:23 PM, Matthew Walker <mwalker@wikimedia.org> wrote:
Whist investigating an orthogonal logging issue I encountered a couple of differences between squid/varnish which I didn't know about:* Varnish does not give subsecond request time informationYes that's correct@ottomata: maybe we can add subsecond request time information to varnish requests?* Varnish does give subsecond request processing time infoYes that's correct.* Varnish calls it 'hit/200' or 'miss/302' instead of 'TCP_MEM_HIT/200' or 'TCP_MISS/302'Yes that's correct.* Varnish does not URL encode the user agent fieldWe never URL encoded the user agent field as far as I know, we did replace space with %20 but have stopped doing that as we are using the tab as separator now. Maybe that patch has not been removed from the squids?Example log lines:
