Linux Performance Tools, Brendan Gregg, part 2 of 2
Tutorial by Brendan Gregg of Netflix for O'Reilly Velocity conference 2015 Santa Clara. Part 2 of 2.

Description: "
There are many performance tools nowadays for Linux, but how do they all fit together, and when do we use them? This tutorial explains methodologies for using these tools, and provides a tour of four tool types: observability, benchmarking, tuning, and static tuning. Many tools will be discussed, including top, iostat, tcpdump, sar, perf_events, ftrace, SystemTap, sysdig, and others, as well observability frameworks in the Linux kernel: PMCs, tracepoints, kprobes, and uprobes.
This tutorial is updated and extended on an earlier talk that summarizes the Linux performance tool landscape. The value of this tutorial is not just learning that these tools exist and what they do, but hearing when and how they are used by a performance engineer to solve real world problems - important context that is typically not included in the standard documentation."

Surprised that this presentation hasn't gotten the number of eyeballs it so rightly deserves in last 4 years !! Great information for linux developers !!
Loved this series.
That's one hell of a fine presentation.
Very useful, especially for beginner like me. So many unknown tools. Once again thanks for the gr8 info.
Great overview! Thanks.
Thank you, for sharing!
Really good, what an interesting guy Brendan Gregg is.
Great! Thanks
I am buying the book.
cool!!!
Why would you need unicode to make a grey scale in your terminal ?
AWSome :)
maybe this one is a little bit advanced
