An Update on PromQL Compatibility Across Vendors

  • Last time we tested Cortex we encountered two minor issues: floating-point input timestamps were not rounded in the same way as in Prometheus, and the system did not support executing queries without a metric name.
  • This is currently not configurable on the Grafana Cloud side, so we had to apply a cross-cutting query tweak to align input timestamps to our reference Prometheus server in the same way, to get comparable results.
  • With this in mind, we tested a Grafana Cloud account via remote_write and their Prometheus-style HTTP query API on both the remaining legacy cluster and a new dedicated blocks-storage cluster, and we got the same 99.62% and 100% test scores as for Cortex itself.
  • MetricFire is still using a slightly outdated version of Cortex, so we ran into similar input timestamp parsing inaccuracies as with Cortex in August, and queries without a metric name are not yet supported due to using chunks-based storage.
