rally

Retrieve Rally benchmark results from an external Elasticsearch metrics store. Use to list past races, get a single race's overall (per-task) results, chart a metric's trend across multiple runs, compare two races, or check whether a run converged — e.g. "show me recent geonames races", "what's the service_time trend for nyc_taxis over the last 30 days?", "compare these two race-ids". Applies when datastore.type = elasticsearch is set in ~/.rally/rally.ini.

Work on Rally's own codebase, not running benchmarks with it. Use when setting up the dev environment, running Rally's tests or linters, navigating its source, debugging Rally's own code, or making changes to Rally itself.

Run Rally benchmarks (races) against Elasticsearch — an existing/external cluster or a Rally-provisioned distribution — and read the summary report. Use when running a race (any pipeline, track, challenge, target-hosts, or auth) or when interpreting throughput, latency, and service_time results.
