  • Product information
  • Release notes

Overview

The Site Reliability Guardian provides an automated change impact analysis to validate service availability, performance, and capacity objectives across various systems. This enables DevOps platform engineers to make the right release decisions for new versions and empowers SREs to apply Service-Level Objectives (SLOs) for their critical services.

Use cases

  • DevOps can automate safe and secure releases by applying a gating mechanism that identifies release issues quickly and prevents poor-quality code from being promoted to production.

  • SREs can leverage on-demand reliability validation by comparing observability data such as service-level objectives against a dedicated release version from the past, or as part of progressive delivery.

Get started

  1. Open the Site Reliability Guardian to create a new guardian.

  2. Specify objectives you would like to validate automatically.

  3. Create a workflow to automate the change impacts analysis.

  4. Trigger a validation on demand or by sending an event to Dynatrace.

  5. Leverage the validation result to enrich your release process.

Details

  • Allows you to define service or application objectives that are validated at specific events or on-demand to detect regressions.

  • Leverages Workflows to execute a customizable default workflow for your automation requirements.

  • Links to a notebook for a detailed root cause analysis of a failed validation.

1.28.0

This release adds a ready-to-use "Releases Inventory" dashboard, giving you an out-of-the-box overview of your release landscape.

Guardian templates that previously relied on deprecated entity selectors have been migrated to Smartscape, giving you a modern and consistent way to select the resources you want to monitor.

DQL reliability has been improved: unquoted variables in objective queries now work correctly, and all timeseries-based template objectives receive a consistent default parameter to ensure predictable query behavior.

Duplicate, edit, and delete buttons now follow the standard missing-permissions pattern, providing consistent feedback when an action is unavailable due to insufficient permissions.

This release introduces lifecycle guardians, enabling you to store and analyze validation results within the Software Development Life Cycle context. You can now create guardians that ingest validations into SDLC events, providing enhanced traceability and integration with your development workflows.

This update improves the guardian creation experience with a clearer interface for selecting between business guardians and lifecycle guardians. You will now find an option in the guardian creation and editing screens that allow you to easily switch between event types, with lifecycle guardians set as the default option for new guardians.

The analysis capabilities have been enhanced with SDLC events integration throughout the application. The overview page now retrieves and displays SDLC event data, while the analysis page provides comprehensive visualization and drilling capabilities into notebooks. Auto-adaptive thresholds now support SDLC events and take failed validations into account for more accurate threshold calculations.
