Crow

Crow is a tool similar to Tempo Vulture and Loki Canary that is used to smoke test Grafana Agent. Crow works by generating metrics, then validating them against Prometheus. Crow uses two endpoints; the traditional /metrics and then /validate that generates the results of Crow checking for successful samples.

Note: The /validate endpoint should only be checked by the Grafana Agent instance that is configured to remote_write.
