Quick Definition (30–60 words)
Multi window burn rate is a measurement of how quickly an error budget is consumed across multiple rolling time windows to detect rapid or sustained degradation. Analogy: like checking several timers on a stove simultaneously to catch both fast boils and long simmers. Formal: a sliding-window rate calculation comparing error events to allowed budget across short and long windows.
What is Multi window burn rate?
Multi window burn rate is a monitoring and SRE concept that computes burn rates of an error budget across multiple rolling time windows (for example 5m, 1h, 24h) to detect both short-lived and sustained incidents. It is NOT a single-window alerting rule or a capacity planning metric by itself.
Key properties and constraints:
- Uses multiple rolling windows to balance sensitivity and stability.
- Compares observed error rate against SLO-derived thresholds.
- Designed to reduce both false positives and late detection.
- Requires reliable telemetry and correct SLO definitions.
- Can be noisy without aggregation, dedupe, and grouping strategies.
- Depends on accurate weighting for windows with different lengths.
Where it fits in modern cloud/SRE workflows:
- Early detection: catches spikes before total budget loss.
- Incident escalation: triggers paging or mitigation when short windows burn fast.
- Automation: feeds auto-remediation runbooks and progressive rollbacks.
- Postmortem: provides time-series evidence of when and how budget was consumed.
Text-only diagram description:
- Imagine three parallel time tapes labeled 5 minutes, 1 hour, and 24 hours.
- Each tape receives tokens when requests fail or latency breaches occur.
- Each tape has a threshold line representing allowed budget consumption scaled to its window.
- A burn-rate engine samples recent events, computes rate per tape, and outputs a combined risk score.
- The risk score routes to alarms, dashboards, and automation.
Multi window burn rate in one sentence
A technique that computes error budget consumption across multiple rolling windows so teams can detect and act on both sudden spikes and slower degradations before SLOs are exhausted.

Business impact:
- Revenue: Fast detection of customer-facing failures reduces transactional revenue loss and conversion drops.
- Trust: Prevents repeated visible failures, protecting brand and user retention.
- Risk: Helps prioritize mitigations where SLA penalties or contractual risks exist.
Engineering impact:
- Incident reduction: Early detection reduces blast radius and downstream failures.
- Velocity: Clear SLO-driven guardrails let teams move faster with confidence.
- Focus: Helps prioritize engineering work that reduces true customer impact.
SRE framing:
- SLIs/SLOs: Multi window burn rate uses SLIs to compute burn across windows and protects SLOs.
- Error budgets: It monitors the rate at which the error budget is consumed across time horizons.
- Toil: Automations tied to burn-rate events reduce manual firefighting.
- On-call: Enables graduated paging rules to reduce pager fatigue while ensuring timely responses.
3–5 realistic “what breaks in production” examples:
- A sudden database failover causes a 10x 5-minute spike in failed requests.
- A gradual memory leak increases tail latencies over several hours, slowly consuming budget.
- A bad deploy increases errors at low volume but persists for 12 hours.
- A third-party API degrades intermittently causing short bursts of timeouts.
- A misconfigured rate limiter starts dropping requests under unusual client patterns.

When should you use Multi window burn rate?
When it’s necessary:
- You have SLOs and want nuanced, time-aware detection of budget consumption.
- You need to distinguish between short severe incidents and long mild degradations.
- You run services with both high-volume short requests and long-running transactions.
When it’s optional:
- Small teams with simple uptime requirements may use single-window burn rates.
- Non-customer-facing internal services with limited SLAs.
When NOT to use / overuse it:
- For metrics that are not tied to customer experience.
- For low-cardinality metrics with insufficient volume (high noise).
- As the only safeguard against cascading failures — pair with other controls.
Decision checklist:
- If production traffic > X per minute and you have an SLO -> use multi-window.
- If you have L3/L4 incidents causing short spikes -> prioritize short-window rules.
- If you suffer long tail degradations -> ensure long windows are included.
Maturity ladder:
- Beginner: Single short and single long window burn alerts, basic dashboards.
- Intermediate: Multi-window with grouping by service and basic automations for rollbacks.
- Advanced: Weighted multi-window engine, dynamic thresholds, ML anomaly fusion, automated remediations and policy enforcement.
How does Multi window burn rate work?
Step-by-step:
- Define SLO and error budget for an SLI (for example availability 99.9% per 30 days).
- Choose multiple rolling windows (e.g., 5m, 1h, 24h) and map allowed budget per window.
- Collect telemetry: counts of good vs bad events and relevant request volumes.
- Compute burn rate per window: observed error rate divided by allowed error rate for that window.
- Normalize and combine window signals to determine risk level (for example, if any window exceeds threshold page).
- Trigger actions: warn in dashboard, create ticket, page on-call, or run automated rollback.
- Record events to incident timeline and adjust SLO or policies postmortem.
Data flow and lifecycle:
- Instrumentation emits SLIs to metrics pipeline.
- Aggregator computes rolling-window counts and burn rates.
- Decision engine applies rules or ML to raise alerts.
- Alert routing sends to on-call, automation, and dashboards.
- Post-incident, data is stored for analysis and SLO adjustment.
Edge cases and failure modes:
- Telemetry lag causes delayed burn calculation.
- Cardinality explosion from many service tags causes aggregation issues.
- Low traffic windows lead to noisy burn rates.
- Metric reset during deploys yields miscounted events.

Frequently Asked Questions (FAQs)
What window lengths should I use for multi-window burn rate?
Typical starting set: 5 minutes, 1 hour, 24 hours. Tune based on traffic patterns and SLO period.
Can multi-window burn rate replace anomaly detection?
No. It complements anomaly detection by focusing on SLO-relevant consumption.
How do I handle low-traffic services?
Apply minimum request thresholds or aggregate across similar services.
How to avoid alert fatigue with multiple windows?
Use severity mapping, dedupe, grouping, and suppression windows.
Do I need a separate tool for burn-rate computation?
Not always; many observability platforms and PromQL can compute it, but a central SLO engine simplifies management.
How should I weight different windows in a combined score?
Weights should reflect business priorities; validate with historical incidents.
What SLIs are most useful with multi-window burn rate?
Availability and latency for customer-facing endpoints; business success metrics for transactions.
How to correlate deploys with burn-rate spikes?
Annotate metrics with deploy markers and include deploy metadata in dashboards.
Can automation be triggered by burn-rate alerts?
Yes, but test automations thoroughly and use human-in-loop for risky actions.
How to measure effectiveness of multi-window burn rate?
Track detection lead time, reduction in user impact, and false positive rates.
Should I use multi-window for internal infra?
Use only if internal SLOs exist and customer impact is meaningful.
How to handle cardinality explosion?
Limit tags, use aggregation, and apply label rollups.
How many teams should share a central SLO engine?
Depends on scale; many teams benefit from a shared engine to standardize policies.
How often should we review SLOs and thresholds?
Quarterly at minimum, and after significant incidents or traffic pattern changes.
What is an acceptable burn-rate alert threshold?
No universal answer. Start with conservative thresholds and tune after collecting data.
Can burn rate detect security incidents?
It can surface unusual patterns but should be combined with SIEM and security workflows.
How do I test burn-rate alerts?
Use synthetic traffic, chaos experiments, and staged failures in pre-prod.
What if telemetry stops during incident?
Detect ingestion gaps and consider fallback rules using logs or sampling.
Conclusion
Multi window burn rate gives teams nuanced visibility into how quickly error budgets are consumed across multiple timescales, enabling faster detection and more measured responses to both rapid and slow degradations. It ties technical metrics to business impact and can power automation when used responsibly.
