OpenSLO

Only Compatible with CLI, Not Kubernetes compatible

This spec can't be used with Kubernetes CRDs, use Kubernetes spec instead.

Sloth supports OpenSLO v1alpha spec, however we need to take into account that it has some restrictions:

  • OpenSLO time window restricted to 30 days.
  • Only Objective ratio metrics are supported.
  • Only Prometheus and PromQL query types are supported.
  • Configuration fields not required by Sloth will be ignored.

Regarding Sloth features, OpenSLO spec doesn't support all of the sloth features:

  • No Prometheus labels support.
  • No alerting support.
  • No SLI plugins support.
  • No Kubernetes support (at least until official OpenSLO CRDs are released).
