[shaig-mahmudov]

Type: Observability / Operations
Priority: Medium

Description

Create version-controlled Grafana dashboards and actionable Prometheus alerts for the Loopin API.

Scope

• Configure Grafana with Prometheus as a data source.
• Add a Loopin API dashboard.
• Include request rate, error rate, latency, JVM, HikariCP, WebSocket, notification, AI and media metrics.
• Add alert rules for critical operational conditions.
• Add a short runbook for each alert.
• Store dashboard and provisioning files in the repository.

Acceptance Criteria

• Grafana loads the Loopin dashboard automatically.
• Dashboard panels display data from Prometheus.
• Alerts cover readiness failure, high 5xx rate, high latency, database pool saturation and background-operation failures.
• Each alert includes a clear description and remediation note.
• Dashboards and alert rules are version controlled.
• No dashboard depends on high-cardinality identifiers.
