README

Query comparator

This docker-compose file will setup the following environment:

  1. 1 M3Comparator node that acts as remote gRPC storage. Provides randomized data based on the incoming query's start time.
  2. 1 M3Query node that connects to the M3Comparator instance, using it as remote storage. Serves queries and remote reads.
  3. 1 Prometheus node that has no scrape settings set, connecting to M3Query instance as a remote_read endpoint.
  4. (optionally) 1 Grafana node with pre-configured graphs corresponding to the queries run by the test.

Mechanism

  • Queries are generated from queries.json, then run against both the Prometheus and M3Query instances, then results are compared.

Usage

  • Use make docker-compatibility-test from the base folder to run the comparator tests.
  • Use CI=FALSE make docker-compatibility-test from the base folder to run the comparator tests, brings up a Grafana instance and does not perform teardown, allowing manual inspection of query differences.

Grafana

Use Grafana by navigating to http://localhost:3000 and using admin for both the username and password. The dashboard should already be populated and working, it should be named Dashboard <git-reference>.
