http-sink

A request sink at /blackhole that accepts any method or subpath, echoes it back, and lets you simulate latency and failures while watching live traffic stats.

Latency simulation

Configure a path and a jitter value in ms. Requests to the exact path get a random delay between 0 and that value before responding.

Failure injection

Configure a path, an error rate (0-1), and a status code. That fraction of requests to the exact path will receive the status code instead of the normal 200 response; the rest respond normally.
