Show HN: Xcapture-BPF – like Linux top, but with Xray vision
Always on Profiling for Production Systems
xcapture-bpf(and xtop) are like the Linux top tool, but extended with x-ray vision and ability to view your performance data from any chosen angle (that eBPF allows to instrument). This may come as a surprise if you’ve worked only for startups running latest ephemeral Ubuntu containers in the cloud :-) For example RedHat started actually supporting eBPF in RHEL 8.1 (Released Nov 2019). Such time-series metrics are useful background info, but do not allow you to drill down into the low level reasons of increased system activity, application resource usage or misbehavior of the OS kernel itself.
