SLO/FAQ

What use cases lead to a negative error budget?

A sustained amount of errors (namely, SLO target not met) may lead to the exhaustion of the error budget and a negative value (until the errors are resolved). In a rolling window, the negative error budget will show up for a while.

What tooling is used to manage SLO metrics, alerts and dashboards?

The tool that SRE uses to manage SLO metrics, dashboards and alerts is Sloth

Sloth provides a manifest language which allows users to express their SLOs in a unified way. Sloth takes these manifests, and generates a unified set of prometheus recording rules which present a consistent SLO metrics format that is consumed by Grafana, and Prometheus Alertmanager.
