Fleet and network in React

Address, data-size and rate types, latency long-tailed so p99 bites

type: ipv4 · bytes · bitrate

This is a fleet and network sheet with address, data-size and rate types, and latency that is long-tailed so the p99 really bites. It shows infrastructure metrics with the right types and the tail statistic that matters for reliability.

Building…

Loading a live grid…

This is the React version. The grid mounts through the createLatticeGrid adapter, which takes its configuration as ordinary props and hands back the live grid through a ref. The grid below is the same one every other tab runs.
