loadgen/

Package command wraps any load tool behind shell commands: start, stop, rate (with {rate}) and status, whose output may be JSON {"running":..,"rate":..,"sent":..,"failed":..}.

Package http is a built-in open-model load generator: requests go out at a fixed rate whatever the latency (no coordinated omission), from this process, for as long as rig runs.

Package kv drives load generators that run as services and read their rate from a key-value store: the rate is written to a key (or one JSON field of it), start and stop scale the generator services, and counters come from metrics queries when configured.
