piccolo-perf - a perfSONAR-lite for routers and SBCs

I have a soft spot for perfSONAR . It’s the gold standard for research and education network performance measurement, and if you run a network that touches ESnet, Internet2, or any of the big R&E backbones, you’ve probably got a perfSONAR node (or ten) somewhere. The problem is that perfSONAR is heavy. It wants a full OS, a stack of services, and real resources. That’s fine for a dedicated measurement box and that has served perfSonar well for 20 years, but it’s a non-starter for a router, a Raspberry Pi at a remote site, or anything else you’d call “constrained.
