From 41d292913a27b629a141e4f084e9011c2dcf7c07 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 7 Nov 2025 22:16:16 +0000 Subject: [PATCH] feat: Add alert endpoints to alert_processor service for dashboard MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented missing alert endpoints that the dashboard requires for health status and action queue functionality. Alert Processor Service Changes: - Created alerts_repository.py: * get_alerts() - Filter alerts by severity/status/resolved with pagination * get_alerts_summary() - Count alerts by severity and status * get_alert_by_id() - Get specific alert - Created alerts.py API endpoints: * GET /api/v1/tenants/{tenant_id}/alerts/summary - Alert counts * GET /api/v1/tenants/{tenant_id}/alerts - Filtered alert list * GET /api/v1/tenants/{tenant_id}/alerts/{alert_id} - Single alert - Severity mapping: "critical" (dashboard) maps to "urgent" (alert_processor) - Status enum: active, resolved, acknowledged, ignored - Severity enum: low, medium, high, urgent API Server Changes: - Registered alerts_router in api_server.py - Exported alerts_router in __init__.py Procurement Client Changes: - Updated get_critical_alerts() to use /alerts path - Updated get_alerts_summary() to use /alerts/summary path - Added severity mapping (critical → urgent) - Added documentation about gateway routing This fixes the 404 errors for alert endpoints in the dashboard. --- services/alert_processor/app/api/__init__.py | 3 +- services/alert_processor/app/api/alerts.py | 222 ++++++++++++++++++
