Generating

Look the file slo_example.yml to see how to parametrize SLOs and generate Prometheus rules by running the following command:

slo-generator -slo.path=slo_example.yml -rule.output rule.yml

SLOs at scale

The Workbook suggests to create classes to simplify how to set a SLO for your services, read details about concepts here

Look at slo_example_with_classes.yml and slo_classes.yml to see how to define classes and associate with your services.

After that, you can run the command specifying the classes:

slo-generator -slo.path=slo_example_with_classes.yml -classes.path slo_classes.yml -rule.output rule.yml

Grafana integration

All generated SLOs are visible by grafana:
