(This is based on Table 4.1 "Linux Crisis Tools" in SysPerf 2.) Some longer notes: [1] bcc and bpftrace have many overlapping tools: the bcc ones are more capable (e.g., CLI options), and the bpftrace ones can be edited on the fly. But that's not to say that one is better or faster than the other: They emit the same BPF bytecode and are equally fast once running. Also note that bcc is evolving and

Sometimes debuggers and profilers are obviously broken, sometimes it's subtle and hard to spot. From my flame graphs page: (Click for original SVG.) This is pretty common and usually goes unnoticed as the flame graph looks ok at first glance. But there are 15% of samples on the left, above "[unknown]", that are in the wrong place and missing frames. The problem is that this system has a default li

The Utilization Saturation and Errors (USE) Method is a methodology for analyzing the performance of any system. It directs the construction of a checklist, which for server analysis can be used for quickly identifying resource bottlenecks or errors. It begins by posing questions, and then seeks answers, instead of beginning with given metrics (partial answers) and trying to work backwards. The re

This is based on my bcc Tutorial, and many also exist in bpftrace. I chose these to find the most performance wins with the fewest tools. Note that runqlat and profile can have noticable overheads, so I'd run these tools for between 10 and 60 seconds only and generate a report. Some are low enough overhead to be run 24x7 if desired (e.g., execsnoop, biolatency, tcplife, tcpretrans). There is alrea

For my AWS re:Invent talk on BPF Performance Analysis at Netflix, I began with a demo of "BPF superpowers" (aka eBPF). The video is on youtube and the demo starts at 0:50 (the slides are here or as a PDF): I'm demonstrating a tool I developed to turn my laptop's wifi signal strength into audio (someone described this as a BPF theremin.) I first developed it as this bpftrace one-liner: bpftrace -e
