Monitorama 2015 talk by Brendan Gregg, Netflix. With our large and ever-changing cloud environment, it can be vital to debug instance-level performance quickly. There are many instance monitoring solutions, but few come close to meeting our requirements, so we've been building our own and open sourcing them. In this talk, I will discuss our real-world requirements for instance-level analysis and monitoring: not just the metrics and features we desire, but the methodologies we'd like to apply. I will also cover the new and novel solutions we have been developing ourselves to meet these needs and desires, which include use of advanced Linux performance technologies (eg, ftrace, perf_events), and on-demand self-service analysis (Vector).
