About:
Oslo is a command-line interface (CLI) tool designed to interact with the OpenSLO specification. It enables developers to validate, parse, and manage SLO (Service Level Objective) configurations defined in YAML files. The tool streamlines the workflow for implementing reliable observability practices within cloud-native environments.
Key Features:
  • Validate OpenSLO YAML definitions against the schema
  • Parse and inspect SLO resources from the command line
  • Integrate SLO management into CI/CD pipelines
  • Support for the OpenSLO specification syntax
Use Cases:
  • Validating SLO definitions before deploying them to observability platforms
  • Automating SLO checks in a GitOps workflow
  • Local development and testing of Service Level Objectives
Alternatives:
  • sloctl – sloctl is the official CLI for Nobl9, which supports OpenSLO but also ties into the Nobl9 platform, whereas oslo is strictly focused on the open-source specification.
