72-c02.1.22-create-function-service-level-agreement-SLA-compliance-for-application-performance-monitoring

Description:

Implement a service to monitor and report on the application’s adherence to Service Level Agreement (SLA) requirements. This includes tracking performance metrics, availability, error incidents, generating compliance status reports, and providing improvement recommendations.

Performance Monitoring

Tracks:

Response time (per API endpoint)

Throughput (requests/sec)

Resource utilization (CPU, memory, disk I/O)

Compares real-time metrics against SLA thresholds (e.g., response time ≤ 500ms).

Availability Monitoring

Calculates:

Uptime/downtime (via heartbeat checks)

Availability % (target: e.g., 99.9% monthly)

Flags deviations from SLA targets.

Error and Fault Detection

Logs and classifies:

Errors (HTTP 5xx, database failures)

Fault severity (critical/major/minor)

Incident frequency (violations/week)

Compliance Status Evaluation

Generates report with:

Compliance score (% of SLA met)

Violation details (metrics breached, duration, root cause)

Historical trends (compliance over 30/60/90 days)

Recommendations for Improvement

Suggests actionable fixes (e.g., "Optimize DB queries for endpoint X," "Scale memory for service Y").
