SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires fastapi, uvicorn, pydantic, requests, and includes scripts (resource) components.

What problem does it solve?

Organizations rely on measurable reliability targets to ensure system availability and predictable performance. This skill provides a structured approach to define SLIs, SLOs, and SLAs, calculate error budgets, and monitor compliance against production metrics.

Core Features & Use Cases

  • Define SLIs and SLOs: Specify availability, latency, freshness, and correctness indicators that align with business goals.
  • Compute and monitor error budgets: Track remaining budgets and burn rates to inform release decisions and capacity planning.
  • Prometheus-backed compliance: Query Prometheus metrics to assess current service compliance and generate actionable insights.
  • Automated dashboards and API access: Expose status via a REST API and integration-friendly dashboards for operators and software engineers.

Quick Start

Define your service's SLO, deploy the monitoring tools, and start evaluating compliance against your Prometheus data.

Frequently Asked Questions about Service Level Objectives (SLO/SLI/SLA)

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I calculate error budgets and burn rates for SLO compliance?▼

Error budgets and burn rates are calculated by defining SLIs and SLOs against production metrics to track remaining availability thresholds and inform release decisions. This skill uses a Python toolchain to automate these calculations.

What is the best way to monitor SLO compliance using Prometheus metrics?▼

Monitoring SLO compliance with Prometheus involves querying production metrics to assess service availability and generate actionable insights. This skill uses a FastAPI service to expose and evaluate these Prometheus-backed checks.

Can I expose SLO and SLA status through an API for automated dashboards?▼

You can expose SLO and SLA status through a REST API to enable integration-friendly automated dashboards. This skill deploys a FastAPI service using Uvicorn to provide programmatic access to reliability metrics.

Do I need FastAPI and Pydantic to define service reliability targets?▼

FastAPI and Pydantic are required dependencies to run the compliance workflow and expose the REST API service. The underlying SLI and SLO definitions are managed through Python scripts that handle error budget calculations.

When should I define SLIs and error budgets for my production services?▼

You should define SLIs and error budgets when your services have clear reliability requirements and need data-driven compliance windows. This enables automated monitoring, burn-rate calculations, and alerting based on production metrics.
