Composite SLOs 2.0​

We're proud to announce the brand-new edition of composite SLOs—Composite SLOs 2.0!

Composite SLOs 2.0 elevates the overall reliability management of complex ecosystems to the next level. Managing numerous data sources and distributed systems often makes it difficult to get a complete view. Composite SLO 2.0 addresses this by unifying all your data, allowing you to integrate multiple SLOs from different sources and projects, effectively eliminating data silos across your monitoring stack.

Composite 2.0 highlights:

  • Flexibility: Assemble SLOs from various data sources and projects to monitor end-to-end user journeys with real-time insights.
  • Data source agnostic approach: Use SLOs based on different data sources in a single composite to unify monitoring across all your distributed data sources. It also simplifies creating composite SLOs because you don't need to configure underlying queries.
  • Weighted components: Assign weights to each SLO component in your composite to accurately reflect their impact on the overall composite.
  • Component impact graph: Quickly identify which SLO component affects your composite error budget the most to address reliability issues promptly.

  • Multi-level hierarchy: Add other composites as components to your composite SLO and view its detailed structure, including all levels of nesting, for a complete overview of your system’s reliability.

note

If you’re already using the previous version of Composite SLOs, rest assured: your existing data will remain unaffected. With this release, you can create Composite SLOs 2.0 using sloctl and the Nobl9 Terraform provider. The Nobl9 Web functionality is on its way, so keep on track of future releases.
