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.
Comand grafana-agent-crow is a correctness checker tool that validates that
scraped metrics are delivered to a remote_write endpoint. Inspired by Loki
Canary and Cortex test-exporter.
