- Sort repositories alphabetically before rendering
- Sort backup disks by serial number
- Prevents display jumping between different orderings on updates
- Consistent display order across refreshes
Bump version to v0.1.214
Co-Authored-By: Claude <noreply@anthropic.com>
- Update BackupData structure to support multiple backup disks
- Scan /var/lib/backup/status/ directory for all status files
- Calculate status icons for backup and disk usage
- Aggregate repository status from all disks
- Update dashboard to display all backup disks with per-disk status
- Display repository list with count and aggregated status
- Agent now extracts "C" + digits pattern (C3, C10) using char parsing
- Removes suffixes like "_ACPI", "_MWAIT" at source
- Reduces JSON payload size over ZMQ
- No regex dependency - uses fast char iteration (~1μs overhead)
- Robust fallback to original name if pattern not found
- Dashboard simplified to use clean names directly

Bump version to v0.1.210
Co-Authored-By: Claude <noreply@anthropic.com>
- Changed CpuData.cstate from String to Vec<CStateInfo>

Provides better visibility into CPU idle state distribution.
Bump version to v0.1.209
Co-Authored-By: Claude <noreply@anthropic.com>
- Changed CpuData.frequency_mhz to CpuData.cstate (String)
- Implemented collect_cstate() to read CPU idle depth from sysfs
- Finds deepest C-state with most accumulated time (C0-C10)
- Updated dashboard to display C-state instead of frequency
- More accurate indicator of CPU activity vs power management

The service_status_cache from discovery only has active_state with
all detailed metrics set to None. During collection, get_service_status()
was returning cached data instead of fetching fresh systemctl show data.
Now always fetch fresh data to populate memory_bytes, restart_count,
and uptime_seconds properly.
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:
- Add memory_bytes, restart_count, uptime_seconds to ServiceInfo
- 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.
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
- Remove memory/disk parsing in legacy metric path
- Remove unused format_disk_size() function
Service resource metrics were slow, unreliable, and never worked
properly since structured data migration. Will be handled differently
in the future.
Service control migrated to SSH, command receiver no longer needed.
- Remove command_receiver Socket from ZmqHandler
- Remove try_receive_command method
- Remove AgentCommand enum
- Remove command_port from ZmqConfig
Changes:
- Rename docker images from 'image_node:18...' to 'I node:18...' for conciseness
- Change image status from 'active' to 'inactive' for neutral informational display
- Images now show with gray empty circle ○ instead of green filled circle ●
Docker images are static artifacts without meaningful operational status, so using inactive status provides neutral gray display that won't trigger alerts or affect service status aggregation.
Fixes random host disconnections caused by blocking operations preventing timely ZMQ packet transmission.
Changes:
- Add run_command_with_timeout() wrapper using tokio for async command execution
- Apply 10s timeout to smartctl (prevents 30+ second hangs on failing drives)
- Apply 5s timeout to du, lsblk, systemctl list commands
- Apply 3s timeout to systemctl show/is-active, df, ip commands
- Apply 2s timeout to hostname command
- Use system 'timeout' command for sync operations where async not needed
Critical fixes:
- smartctl: Failing drives could block for 30+ seconds per drive
- du: Large directories (Docker, PostgreSQL) could block 10-30+ seconds
- systemctl/docker: Commands could block indefinitely during system issues
With 1-second collection interval and 10-second heartbeat timeout, any blocking operation >10s causes false "host offline" alerts. These timeouts ensure collection completes quickly even during system degradation.
Agent changes:
- Changed docker ps and docker images commands to run without sudo
- cm-agent user is already in docker group, so sudo is not needed
- Fixes "unable to change to root gid: Operation not permitted" error
- Systemd security restrictions were blocking sudo gid changes
This fixes Docker container and image collection on systems with
systemd security hardening enabled.
Updated to version 0.1.178
Agent changes:
- Log stderr output when docker images command fails
- This will show the actual error message (e.g., permission denied, docker not found)
- Helps diagnose why docker images collection is failing
Updated to version 0.1.177
Agent changes:
- Changed debug!() to info!() for Docker collection logs
- This allows logs to show with default RUST_LOG=info setting
- Added info import to tracing use statement
Now logs will be visible in journalctl without needing to change log level:
- "Collecting Docker sub-services for service: docker"
- "Found X Docker containers"
- "Found X Docker images"
- "Total Docker sub-services added: X"
Updated to version 0.1.176
Agent changes:
- Added debug logging to Docker images collection function
- Log when Docker sub-services are being collected for a service
- Log count of containers and images found
- Log total sub-services added
- Show command failure details instead of silently returning empty vec
This will help diagnose why Docker images aren't showing up as sub-services
on some hosts. The logs will show if the docker commands are failing or if
the collection is working but data isn't being transmitted properly.
Updated to version 0.1.175
Agent changes:
- Added get_docker_images() function to list all Docker images
- Use docker images to show stored images with repository:tag and size
- Display images as sub-services under docker service with size in parentheses
- Skip dangling images (<none>:<none>)
- Images shown with active status (always present when listed)
Example display:
● docker active 139M 1MB
├─ ● docker_gitea active
├─ ○ docker_old-app inactive
├─ ● image_nginx:latest (142MB)
├─ ● image_postgres:15 (379MB)
└─ ● image_gitea:latest (256MB)
Updated to version 0.1.174
Agent changes:
- Use docker ps -a to show ALL containers (running and stopped)
- Map container status: Up -> active, Exited/Created -> inactive, other -> failed
- Display Docker containers as sub-services under the docker service
- Each container shown with proper status indicator
Example display:
● docker active 139M 1MB
├─ ● docker_gitea active
├─ ○ docker_old-app inactive
└─ ● docker_immich active
Updated to version 0.1.173
