I couldn&#x27;t agree more; Brendan Gregg is awesome. I finally created an account just to say this. His materials on Linux performance analysis and monitoring[0] are phenomenal. The analysis and observability maps he made are quite helpful to see the big picture and put specific tools in their proper context. I also particularly appreciate his materials on perf.<p>Maybe I&#x27;m being too much of a fanboy, but I appreciate good materials when I come across them.<p>[0] <a href="http:&#x2F;&#x2F;www.brendangregg.com&#x2F;linuxperf.html" rel="nofollow">http:&#x2F;&#x2F;www.brendangregg.com&#x2F;linuxperf.html</a>
