Yukab Panel Stress Diagnostic

Controlled workload generator that measures Yukab CPU, memory, persistent storage, bandwidth, logging, long-request, health, and cgroup behavior.

Authentication required. Set STRESS_TOKEN to a strong random secret. Stress endpoints stay disabled when the token is absent.

Full diagnostic report limit-aware

The diagnostic now reads the real cgroup RAM/CPU limits and current /data capacity before choosing workload sizes. It will not accept impossible 25–50 GiB values on a small server.

CPU saturation

Runs worker threads continuously for a bounded duration.

Memory pressure

Commits a real Buffer. Requests are server-side clamped to the detected safe cgroup headroom.

Persistent disk write

Writes real bytes to /data/yukab-stress-test.bin. Requests are clamped to available persistent capacity.

Bandwidth stream

Streams an exact binary response through the reverse proxy.

Log pressure

Writes structured lines to stdout to exercise Docker log limits and rotation.

Held connection

Leaves an HTTP response open for a bounded period to exercise proxy timeout behavior.
