CHAOS
Adversarial test harness for distributed systems.
CHAOS is a transparent in-line WAN-emulation appliance for measurement-grade test and evaluation of devices under test.
Configure chaosd, bind the data ports, start the daemon, and apply your first per-direction impairment with the chaos CLI.
The CHAOS domain model — directions, the impairment composite, the qdisc stack, applied-state read-back, and the daemon architecture.
The full set of impairment kinds CHAOS applies per direction — latency, loss, rate, queue, duplication, reordering, corruption — and their wire shapes.
How chaosd programs and reads the egress qdisc stack through rtnetlink, the read-back contract, and live statistics.
The chaosd HTTP/JSON control surface — system info, per-direction impairment read/apply/clear, live statistics, and the calibration baseline.
The chaos operator CLI — one-shot subcommands, the interactive shell, and the live data-plane monitor.
How CHAOS measures impairment accuracy against tolerance bands, and the calibration baseline surfaced by the daemon.
chaosd configuration, filesystem layout, capabilities, logging, and lifecycle on the CHAOS appliance.
What CHAOS ships today, the subsystems planned for later phases, and how to tell present behavior from roadmap intent.
