Add comprehensive PMG monitoring with mail statistics, queue depth tracking,
spam distribution analysis, and quarantine monitoring. Includes full discovery
support and UI consistency improvements across all Proxmox products.
Backend:
- Add pkg/pmg package with complete API client for PMG operations
- Implement mail statistics collection (inbound/outbound, spam, virus, bounces)
- Add queue depth monitoring (active, deferred, hold, incoming queues)
- Support spam score distribution and quarantine totals
- Add PMG-specific discovery logic to differentiate from PVE on port 8006
- Extend mock data generator with realistic PMG instances and metrics
- Add PMG node configuration support in config system
Frontend:
- Create MailGateway.tsx component with detailed PMG dashboard
- Display mail flow statistics with time-series charts
- Show queue depth with color-coded warnings (>50 messages or >30min age)
- Add spam distribution histogram and quarantine status
- Support cluster node status with individual queue monitoring
- Add PMG to network discovery with purple branding and mail icon
- Implement conditional navigation (hide PMG tab when no instances configured)
- Standardize discovery UI controls across PVE/PBS/PMG settings pages
API:
- Add /api/config/pmg endpoints for node configuration
- Support PMG-specific monitoring toggles (mail stats, queues, quarantine)
- Extend system settings with PMG configuration options
Discovery:
- Detect PMG vs PVE on shared port 8006 using /api2/json/statistics/mail endpoint
- Return 'pmg' type for mail gateway servers in discovery results
- Update DiscoveryModal to display PMG servers with appropriate styling
This completes ecosystem monitoring support for all three Proxmox products:
Proxmox VE, Proxmox Backup Server, and Proxmox Mail Gateway.
Implements comprehensive Docker monitoring with a dedicated agent that collects
container metrics and reports them to the main Pulse server. Adds Docker-specific
alert rules and threshold management with a redesigned UI.
Backend changes:
- Add Docker agent binary with container metrics collection
- Implement Docker host and container models with CPU/memory tracking
- Add Docker-specific alert types (offline, state, health)
- Extend threshold system to support Docker resources
- Add WebSocket message types for Docker agent communication
- Implement Docker agent API endpoints for registration and metrics
Frontend changes:
- Add Docker monitoring page with host/container views
- Add Docker agent settings panel for configuration
- Reorganize thresholds page with Proxmox/Docker tabs
- Add Docker-specific alert threshold management
- Improve layout consistency with vertical stacking
- Fix defensive null checks and TypeScript errors
This change enables monitoring of Docker containers across multiple hosts
with the same alerting and threshold capabilities as Proxmox resources.
Frontend (TypeScript):
- Eliminated all 'any' types (7 → 0)
- Added proper types for event system with generics
- Fixed event data interfaces with specific types
- Replaced any with unknown where appropriate
Backend (Go):
- Created central types.go with 30+ typed API structures
- Eliminated all interface{} in /internal/api package (158 → 0)
- Replaced map[string]interface{} with typed structs:
- ChartResponse, VMChartData, NodeChartData, StorageChartData
- DiagnosticsInfo with NodeDetails, ClusterInfo, PBSDetails
- StorageChartsResponse with StorageMetrics
- Improved compile-time type safety for all API responses
Benefits:
- Better IDE support and autocomplete
- Compile-time error detection
- Clearer API contracts
- Improved maintainability
All tests passing, service running successfully with typed code.
