Defining SLIs and SLOs involves establishing measurable indicators like availability and latency, setting target percentages such as 99.9%, and calculating error budgets to manage service reliability targets effectively.

Calculating error budgets from SLO targets involves defining your reliability target percentage over a specific window like 28 days, then using PromQL to measure the remaining allowable failures for your service.

Generating Prometheus alerting rules for SLO monitoring uses PromQL queries to track SLI metrics, triggering notifications when error budget consumption accelerates too quickly within the configured SLO window.

Common SLI types to track for SRE practices include availability, latency, and durability, which provide measurable targets to balance service reliability with development velocity.

Yes, you can define an availability SLI for your API with a 99.9% SLO target over a 28-day window, then configure alerts to notify you if the error budget is consumed too quickly.

Error budget management is needed for API reliability because it calculates and tracks the allowable failure rate against your SLO, balancing strict reliability targets with ongoing development velocity.
