Replace hardcoded terminal width thresholds with dynamic calculation
based on actual column requirements. Column visibility now adapts
correctly at 58, 52, 43, and 34 character widths instead of the
previous arbitrary 80, 60, 45 thresholds.
- Add width constants for each column (NAME=23, STATUS=10, etc)
- Calculate cumulative widths dynamically for each layout tier
- Ensure header and data formatting use consistent width values
- Fix service name truncation to respect calculated column width
Service panel now dynamically shows/hides columns based on terminal width:
- ≥80 chars: All columns (Name, Status, RAM, Uptime, Restarts)
- ≥60 chars: Hide Restarts only
- ≥45 chars: Hide Uptime and Restarts
- <45 chars: Minimal (Name and Status only)
Improves dashboard usability on smaller terminal sizes.
- Sort repositories alphabetically before rendering
- Sort backup disks by serial number
- Prevents display jumping between different orderings on updates
- Consistent display order across refreshes

Shared:
- Add memory_bytes, restart_count, uptime_seconds to ServiceData
Agent:
- Add new fields to ServiceStatusInfo struct
- Fetch MemoryCurrent, NRestarts, ExecMainStartTimestamp from systemctl show
- Calculate uptime from start timestamp
- Parse and populate new fields in ServiceData
- Remove unused load_state and sub_state fields
Dashboard:

- Update header: Service, Status, RAM, Uptime, ↻ (restarts)
- Format memory as MB/GB
- Format uptime as Xd Xh, Xh Xm, or Xm
- Show restart count with ! prefix if > 0 to indicate instability
All metrics obtained from single systemctl show call - zero overhead.
Changed header from 4 columns to 2 columns:
- Before: Service, Status, RAM, Disk
- After: Service, Status
Matches the removal of memory_mb and disk_gb fields.
Complete removal of service resource metrics:
Agent:
- Remove memory_mb and disk_gb fields from ServiceData struct
- Remove get_service_memory_usage() method
- Remove get_service_disk_usage() method
- Remove get_directory_size() method
- Remove unused warn import
Dashboard:
- Remove memory_mb and disk_gb from ServiceInfo struct
- Remove memory/disk display from format_parent_service_line

Service resource metrics were slow, unreliable, and never worked
properly since structured data migration. Will be handled differently
in the future.
Emoji rendering in terminals can be very slow, especially when rendered in the hot path (every frame for every docker image). The whale emoji 🐋 was causing significant rendering delays.
Temporary change to ASCII 'D' to test if emoji was the performance issue.
Docker images now display with distinctive 🐋 whale icon in blue (highlight color) instead of status icons. This provides clear visual identification that these are docker images while not implying operational status.
Dashboard changes:
- Sort child interfaces under physical NICs with VLANs first (by VLAN ID ascending)
- Non-VLAN virtual interfaces sorted alphabetically by name
- Applied same sorting to both nested children and standalone virtual interfaces
Example output order:
- wan (vlan 5)
- lan (vlan 30)
- isolan (vlan 32)
- seclan (vlan 35)
- br-48df2d79b46f
- docker0
- tailscale0
Updated to version 0.1.171
Agent changes:
- Parse /proc/net/vlan/config to extract VLAN IDs for interfaces
- Detect primary physical interface via default route
- Auto-assign primary interface as parent for virtual interfaces without explicit parent
- Added vlan_id field to NetworkInterfaceData
Dashboard changes:
- Display VLAN ID in format "interface (vlan X): IP"
- Show VLAN IDs for both nested and standalone virtual interfaces
This ensures virtual interfaces (docker0, tailscale0, etc.) are properly nested
under the primary physical NIC, and VLAN interfaces show their IDs.
Updated to version 0.1.170
Agent changes:
- Filter out ifb* interfaces from network display
- Parse @parent notation for VLAN interfaces (e.g., lan@enp0s31f6)
- Show physical interfaces even without IP addresses
- Only filter virtual interfaces that have no IPs
- Extract parent interface relationships for proper nesting
Dashboard changes:
- Nest VLAN/child interfaces under their physical parent
- Show physical NICs with status icons even when down
- Display child interfaces grouped under parent interface
- Keep standalone virtual interfaces at root level
Updated to version 0.1.169

Version bump to 0.1.165
Network interfaces now display without status icons since there's no meaningful status to show. Just shows interface name and IP addresses with subnet compression.
Version bump to 0.1.164
Compress IPv4 addresses from same subnet to save space. Shows first IP in full (192.168.30.1) and subsequent IPs in same subnet with only last octet (100, 142).
Version bump to 0.1.163
Extend NixOS collector to gather network interfaces using ip command JSON output. Display all interfaces with IPv4 and IPv6 addresses in Network section above CPU metrics. Filters out loopback and link-local addresses.

- Fix physical drive serial number display in dashboard
- Improve pool health calculation for arrays with multiple disks
- Support proper tree symbols for multiple parity drives
- Read git commit hash from /var/lib/cm-dashboard/git-commit for Build display
- Fix NVMe serial number parsing to handle whitespace variations

- Fix mount point label styling to match other labels
Updates disk collector and dashboard to show drive serial numbers
instead of device names (sdX) for MergerFS data/parity drives.
Agent extracts serial numbers from SMART data and dashboard
displays them when available, falling back to device names.
Updated the dashboard system widget to properly display MergerFS storage
pools in the exact format described in CLAUDE.md:
- Pool header showing "mergerfs (2+1):" format
- Total usage line: "├─ Total: ● 63% 2355.2GB/3686.4GB"
- Data Disks section with tree structure
- Individual drive entries: "│ ├─ ● sdb T: 24°C W: 5%"
- Parity drives section: "├─ Parity: ● sdc T: 24°C W: 5%"
- Mount point footer: "└─ Mount: /srv/media"
The dashboard now processes both data_drives and parity_drives arrays from
the agent data correctly and renders the complete MergerFS pool hierarchy
with proper status indicators, temperatures, and wear levels.
Storage display now matches the enhanced tree structure format specified
in documentation with correct Unicode tree characters and spacing.
Replace timestamp parsing with direct display of start_time from backup TOML file to ensure timestamp always appears regardless of format. Remove empty line spacing above backup section for compact layout.
Changes:
- Remove parsed timestamp fields and use raw start_time string from TOML
- Display backup time directly from TOML file without parsing
- Remove blank line above backup section for tighter layout
- Simplify BackupData structure by removing last_run and next_scheduled fields
Version bump to v0.1.150
Replace standalone backup widget with compact backup section in system widget displaying disk serial, temperature, wear level, timing, and usage information.
Changes:
- Remove standalone backup widget and integrate into system widget
- Update backup collector to read TOML format from backup script
- Add BackupDiskData structure with serial, usage, temperature, wear fields
- Implement compact backup display matching specification format
- Add time formatting utilities for backup timing display
- Update backup data extraction from TOML with disk space parsing
Version bump to v0.1.149
- Remove duplicate status string fields from ServiceData and SubServiceData
- Use only Status enum as single source of truth for service status
- Agent calculates Status enum using calculate_service_status()
- Dashboard converts Status enum to display text for UI
- Implement flexible metrics system for sub-services with label/value/unit
- Fix status icon/text mismatches (inactive services now show gray circles)
- Ensure perfect alignment between service icons and status text
Fully restored CM Dashboard as a complete monitoring system with working
status evaluation and email notifications.
COMPLETED PHASES:
✅ Phase 1: Fixed storage display issues
- Use lsblk instead of findmnt (eliminates /nix/store bind mount)
- Fixed NVMe SMART parsing (Temperature: and Percentage Used:)
- Added sudo to smartctl for permissions
- Consistent filesystem and tmpfs sorting
✅ Phase 2a: Fixed missing NixOS build information
- Added build_version field to AgentData
- NixOS collector now populates build info
- Dashboard shows actual build instead of "unknown"
✅ Phase 2b: Restored status evaluation system
- Added status fields to all structured data types
- CPU: load and temperature status evaluation
- Memory: usage status evaluation
- Storage: temperature, health, and filesystem usage status
- All collectors now use their threshold configurations
✅ Phase 3: Restored notification system
- Status change detection between collection cycles
- Email alerts on status degradation (OK→Warning/Critical)
- Detailed notification content with metric values
- Full NotificationManager integration
CORE FUNCTIONALITY RESTORED:
- Real-time monitoring with proper status evaluation
- Email notifications on threshold violations
- Correct storage display (nvme0n1 T: 28°C W: 1%)
- Complete status-aware infrastructure monitoring
- Dashboard is now a monitoring system, not just data viewer
The CM Dashboard monitoring system is fully operational.
Implements clean structured data collection eliminating all string metric
parsing bugs. Collectors now populate AgentData directly with type-safe
field access.
Key improvements:
- Mount points preserved correctly (/ and /boot instead of root/boot)
- Tmpfs discovery added to memory collector
- Temperature data flows as typed f32 fields
- Zero string parsing overhead
- Complete removal of MetricCollectionManager bridge
- Direct ZMQ transmission of structured JSON
All functionality maintained: service tracking, notifications, status
evaluation, and multi-host monitoring.
Update storage display to match CLAUDE.md specification:
- Show drive temp/wear on main line: nvme0n1 T: 25°C W: 4%
- Display individual filesystems as sub-items: /: 55% 250.5GB/456.4GB
- Remove Total usage line in favor of filesystem breakdown
Clean up code warnings:
- Remove unused heartbeat methods and fields
- Remove unused backup widget fields and methods
- Add allow attributes for legacy methods
Remove parentheses from drive temperature/wear display to match the
hierarchical format specified in documentation. Drive details now show
directly with status icons as 'nvme0n1 T: 25°C W: 4%' format.
The structured data bridge conversion was only converting individual
drive metrics (temperature, wear) and filesystem metrics, but wasn't
generating the aggregated total usage metrics expected by the storage
widget (disk_{drive}_total_gb, disk_{drive}_used_gb, disk_{drive}_usage_percent).
This caused physical drives to display "—% —GB/—GB" instead of actual
usage statistics.
Updated the bridge conversion to calculate drive totals by aggregating
all filesystems on each drive:
- total_used = sum of all filesystem used_gb values
- total_size = sum of all filesystem total_gb values
- average_usage = (total_used / total_size) * 100
Now physical drives like nvme0n1 properly display total usage aggregated
from all their filesystems (e.g., /boot + / = total drive usage).
