Resolves#641
## Problem
When a VM migrates between Proxmox nodes, Pulse was treating it as a new
resource and discarding custom alert threshold overrides. This occurred
because guest IDs included the node name (e.g., `instance-node-VMID`),
causing the ID to change when the VM moved to a different node.
Users reported that after migrating a VM, previously disabled alerts
(e.g., memory threshold set to 0) would resume firing.
## Root Cause
Guest IDs were constructed as:
- Standalone: `node-VMID`
- Cluster: `instance-node-VMID`
When a VM migrated from node1 to node2, the ID changed from
`instance-node1-100` to `instance-node2-100`, causing:
- Alert threshold overrides to be orphaned (keyed by old ID)
- Guest metadata (custom URLs, descriptions) to be orphaned
- Active alerts to reference the wrong resource ID
## Solution
Changed guest ID format to be stable across node migrations:
- New format: `instance-VMID` (for both standalone and cluster)
- Retains uniqueness across instances while being node-independent
- Allows VMs to migrate freely without losing configuration
## Implementation
### Backend Changes
1. **Guest ID Construction** (`monitor_polling.go`):
- Simplified to always use `instance-VMID` format
- Removed node from the ID construction logic
2. **Alert Override Migration** (`alerts.go`):
- Added lazy migration in `getGuestThresholds()`
- Detects legacy ID formats and migrates to new format
- Preserves user configurations automatically
3. **Guest Metadata Migration** (`guest_metadata.go`):
- Added `GetWithLegacyMigration()` helper method
- Called during VM/container polling to migrate metadata
- Preserves custom URLs and descriptions
4. **Active Alerts Migration** (`alerts.go`):
- Added migration logic in `LoadActiveAlerts()`
- Translates legacy alert resource IDs to new format
- Preserves alert acknowledgments across restarts
### Frontend Changes
5. **ID Construction Updates**:
- `ThresholdsTable.tsx`: Updated fallback from `instance-node-vmid` to `instance-vmid`
- `Dashboard.tsx`: Simplified guest ID construction
- `GuestRow.tsx`: Updated `buildGuestId()` helper
## Migration Strategy
- **Lazy Migration**: Configs are migrated as guests are discovered
- **Backwards Compatible**: Old IDs are detected and automatically converted
- **Zero Downtime**: No manual intervention required
- **Persisted**: Migrated configs are saved on next config write cycle
## Testing Recommendations
After deployment:
1. Verify existing alert overrides still apply
2. Test VM migration - confirm thresholds persist
3. Check guest metadata (custom URLs) survive migration
4. Verify active alerts maintain acknowledgment state
## Related
- Addresses similar issues with guest metadata and active alert tracking
- Lays groundwork for any future guest-specific configuration features
- Aligns with project philosophy: correctness and UX over implementation complexity
Added explicit onKeyDown handler to stop event propagation when Enter
is pressed in the ignored container prefixes textarea. This ensures
newlines can be properly entered to separate multiple prefixes.

Extends the Docker monitoring and alerting system to track writable layer
usage as a percentage of the container's root filesystem. This helps
identify containers with bloated copy-on-write layers before they
consume excessive disk space.
- Add disk threshold to DockerThresholdConfig (default: 85% trigger, 80% clear)
- Evaluate disk alerts for running containers when RootFilesystemBytes > 0
- Include disk metadata (writable layer, total filesystem, block I/O stats)
- Update frontend to display and configure disk thresholds
- Add test coverage for disk usage alert hysteresis
- Document disk monitoring in DOCKER_MONITORING.md
Per-container and per-host overrides apply to disk thresholds the same
way they do for CPU and memory.
Fixes build failure caused by unescaped apostrophes in single-quoted
strings. The Vite/Babel parser was failing on "You'll" and "you'll"
in ActivationModal.tsx, preventing successful frontend builds.
Replace harsh/technical language with clearer, more positive messaging:
BEFORE → AFTER:
- "No alert violations detected during observation yet" → "All systems healthy — no alerts triggered"
- "Monitoring is live; notifications will start after..." → "Monitoring is active. Review your settings..."
- "24h observation ending" → "24-hour setup period ending soon"
- "Review alerts before activating" → "Ready to activate notifications"
- "breached thresholds" → "triggered"
- "violations" → "alerts"
Key improvements:
- Removed jargon: "observation window", "during observation"
- Removed ominous language: "yet", harsh "violations"
- More conversational: "You'll receive" vs "will dispatch to configured destinations"
- Positive framing: "All systems healthy" vs absence-focused language
- Clearer actions: "turning on alerts" vs "enabling notifications"
- Enthusiastic success messages: "Notifications activated!" with exclamation
Affected components:
- ActivationBanner.tsx: 4 text improvements
- ActivationModal.tsx: 5 text improvements
Impact: Better first-run UX, less intimidating language, clearer call-to-action
Discovery Fixes:
- Always update cache even when scan finds no servers (prevents stale data)
- Remove automatic re-add of deleted nodes to discovery (was causing confusion)
- Optimize Docker subnet scanning from 762 IPs to 254 IPs (3x faster)
- Add getHostSubnetFromGateway() to detect host network from container
Frontend Type Fixes:
- Fix ThresholdsTable editScope type errors
- Fix SnapshotAlertConfig index signature
- Remove unused variable in Settings.tsx
These changes make discovery faster, more reliable, and fix the issue where
deleted nodes would persist in the discovery cache or immediately reappear.
- Add comprehensive test coverage for alerts package with 285+ new tests
- Implement ThresholdsTable component with metric thresholds display
- Enhance Alerts page UI with improved layout and metric filtering
- Add frontend component tests for Alerts page and ThresholdsTable
- Set up Vitest testing infrastructure for SolidJS components
- Improve config persistence with better validation
- Expand discovery tests with 333+ test cases
- Update API, configuration, and Docker monitoring documentation
