iperf3 network throughput

v0.1.0

Active network throughput measurement with iperf3 — TCP bandwidth and UDP jitter / packet loss — between two nodes in the fleet. Run the one-shot server on one runner, then probe it with the client from another. Use to answer "what is the real bandwidth (or loss) between these two hosts?"

Actions

Required binaries. Install these on the host before relying on the pack — an action that calls a missing one fails at run time.

Install

emisar pack install validates the pack and verifies its content hash before copying it into /etc/emisar/packs. The --hash below pins the install to the exact bytes on this page — a tampered copy is rejected. After install, reload the runner; it re-reads the catalog and advertises every action.

content hash: sha256:4a80767927aaa86d9a4883735afcc2d8a03b745031451f7a0c68244c65d99349

on the runner host

sudo emisar pack install iperf3 \
  --hash sha256:4a80767927aaa86d9a4883735afcc2d8a03b745031451f7a0c68244c65d99349 \
  --dest /etc/emisar/packs

# Reload so the runner re-reads the catalog:
sudo systemctl reload emisar
