Service Levels — Promise What You Can Prove

SLO and SLA management on top of your Uptime, Monitoring, and Load Testing data. Normalize signals from every source, track error budgets, alert on burn rate, and publish a customer-facing status page from the same numbers your auditor sees.

One Number · One Source of Truth

Cross-Source SLI Normalization — Uptime + Monitoring + Load Testing.

Every objective points at one source: an Uptime check, a Monitoring profile / datasource / measurement, or a Load Testing datasource. The Service Levels evaluator turns each one into the same shape — Good count, Effective count, NoData count, bucket-aligned. That’s how the same “Checkout availability ≥ 99.9%” number is comparable whether the signal is an HTTP probe, a synthetic Citrix session, or a load test pass rate.

Three source families
Uptime checks · Monitoring measurements · Load Testing datasources
NoData is a first-class state
Treat it as failure (default) or carve it out per objective.
Bucket-alignment warning
Flagged during setup when the bucket size doesn’t divide the source interval.
One number, every audience
The same 99.9% target backs Health, Violations, the public status page, and the audit ledger.

Guided Setup

5-Step SLO Setup Wizard.

Service, Objective, Source, Window, Review. Every field has a “what is this?” help card on the right. Bucket-alignment warnings fire client-side before the backend rejects you.

Service

Name, environment, timezone, owner, tier, sensitivity.

Error Budgets & Burn-Rate Alerts

Budget — How Much Failure Can You Still Afford?

For every objective, the platform tracks how much of the error budget has been spent in the current window, and how fast you’re spending it.

Per-objective budget view
Budget total, consumed, remaining (% of total), and burn rate per hour.
Alert rules
Fire on Breached, NoData failure, or At risk (high budget burn) — each with a configurable severity.
Alert events feed
Every fire — with bucket-start and created-at timestamps for audit.
Business hours & exclusions
Maintenance windows and incidents don’t count against the budget.

Health · Violations · Latest Snapshot

Compliance at a glance, violations you can drill.

One window selector drives the dashboard at /service-levels/health and the audit ranges at /service-levels/violations.

Health
Per-service rolling window (1–365 days). Per-objective Good / Effective / NoData counts. Latest active snapshot rows, and on-demand “Evaluate now”.
Violations
Breach and NoData ranges side by side — objective, source, reason, bucket span, and compliance % per range. Same window selector as Health.

Audit-Grade History

Every Change Tracked. Every Number Reproducible.

Version ledger with checksum chain
Every objective edit creates a new version with effective-from / effective-to UTC timestamps.
Recalculation jobs
Replay any historical window with the definitions that were active at the time. The API enforces one active recalc at a time so the audit trail stays clean.
JSON / CSV exports of snapshots and violations
For auditors, board reports, and whatever spreadsheet legal sends back.

Access Control · Sensitivity Masking

Show Customers What They Need. Hide What They Don’t.

Per-service ACL
Allow / deny principal lists per service.
Mask sensitive fields
A per-ACL toggle that hides sensitive fields from principals who aren’t on the allow list.
Tenant-scoped reads and writes
Definitions carry an optional tenant id. The API honours an X-Tenant-Id header — one appliance can scope services and snapshots per tenant.

Public Status Pages · LG059

A Customer-Facing Status Page From the Same Numbers Your Auditor Sees.

The same Service Levels snapshots that drive your internal Health view drive a public, anonymously-served page at /status-pages/{slug}. No second data pipeline. No reconciliation. One source of truth.

Per-page slug
customer-portal, b2b-api, anything URL-safe.
Published or Draft
Drafts stay operator-only; published pages render without authentication.
Pick which services appear
One page per audience — every page a curated subset.
Title is customer-facing copy
No internal naming leaks.
Operator-served, anonymously delivered
Served by the platform/appliance at /status-pages/{slug} — confirm with engineering that public rendering is enabled in your target build.

Scheduler · Storage

Operator controls — evaluation cadence, storage backend, schema provisioning.

Scheduler
Enabled / disabled state, evaluation interval and lookback window (minutes), max services per run, next-run and last-run details, plus an on-demand all-services evaluation cycle.
Storage
Authoritative snapshot store — SQL Server or PostgreSQL. Test connection and provision schema from the UI. Managed appliance ships PostgreSQL pre-configured, no DBA required.
