SLO Dashboard

Each SLO has a linked dashboard that shows:

• Current SLI ratio over the selected window

• Error budget remaining

• Good events versus total events

• Burn rate trends

The dashboard is created automatically when the SLO is created.

SLO status reference

An SLO can appear in these states:

• Healthy: target is being met and budget is intact

• At Risk: budget is running low

• Violated: the SLO has been breached

• Warning: a slow burn alert is firing

• Degraded: a fast burn alert is firing

• No Data: there is not enough metric data to evaluate

• Disabled: the SLO is administratively disabled

Best practices

Set the right target

• Start with 99.5% for internal services

• Start with 99.9% for customer-facing services

• Avoid targets above 99.99% unless your platform can support it

• Revisit targets regularly using actual SLI data

Configure alerts well

• Enable both fast and slow burn alerts for production services

• Start with the default thresholds

• Route fast burn alerts to an on-call channel

• Route slow burn alerts to a team channel for review

Choose metrics carefully

• Prefer counter metrics for both good and total events

• Make sure the total metric includes all attempts

• Prefer service-level metrics over per-instance metrics when possible

Pick a stable time window

• 28d is the recommended default

• 7d can help during early setup and tuning

• avoid windows shorter than 24h for production SLOs

Glossary

• SLI: the measured ratio of good events to total events

• SLO: the target percentage the SLI must meet over a time window

• Error Budget: the allowed unreliability, calculated as 100% − SLO Target

• Error Budget Remaining: the portion of the budget not yet consumed

• Burn Rate: how fast the budget is being consumed

• Fast Burn: alert for sudden high-severity outages

• Slow Burn: alert for gradual sustained degradation

• Multi-window alert: alert that checks two windows to reduce false positives

• Time Window: rolling evaluation period such as 28d

• Notification Channel: destination that receives SLO alerts

• PromQL: Prometheus Query Language used to define SLI metrics and alert queries
