Create Site Reliability Guardian

Site reliability guardians are a mechanism to automate analysis when changes are made. They can be used in production (on a CRON) or as deployment checks (eg. pre and post deployment health checks, security checks, infrastructure health checks).

We will create a guardian to check the checkoutservice microservice which is used during the purchase journey.

• Press ctrl + k search for Site Reliability Guardian and select the app.
• Click + Guardian to add a new guardian.
• Under Four Golden Signals choose Use template.
• Click Run query and toggle 50 rows per page to see more services.
• Select the checkoutservice. Click Apply to template (1).
• Hover over the Saturation objective and delete it (there are no resource statistics from OpenTelemetry available so this objective cannot be evaluated).
• At the top right of the screen, customise the guardian name to be called Three golden signals (checkoutservice).
• Click Save

Note: This process can be automated for at-scale usage using Monaco or Terraform.
