They use tools like Logster to aggregate Apache logs into Graphite for generating graphs of metrics like response times. Profiling tools help identify slow database queries, services, and third party calls. The goal is
Seldom do we get to hear stories of the bumps and bruses earned by a popular website during its formative years. Ross Snyder, a Sr. Software Engineer at Etsy, changes that with an engaging talk he gave at Surge 2011: Scaling Etsy: What Went Wrong, What Went Right.
