There's an arms race to add eBPF (BPF) to commercial observability products, and in this post I'll describe how to quickly do that. This is also applicable for people adding it to their own in-house monitoring systems. You might not even like BPF. You likely already have agents running on all your customer systems.

This talk originated from my updates to [Systems Performance 2nd Edition], and this was the first time I've given this talk in person! CXL in a way allows a custom memory controller to be added to a system, to increase memory capacity, bandwidth, and overall performance. Ford, et al., “TCP

For example, iostat(1), or a monitoring agent, may tell you your average disk latency, but not the distribution of this latency. For smaller environments, it can be of more use helping eliminate latency outliers. I [previously] wrote about bpftrace vs other tracers, including [BCC] (BPF Compiler Collection). system(".")
