The USE Method
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

How To Add eBPF Observability To Your Product
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
