- 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
Bump version to v0.1.208

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
Agent changes:
- Changed docker ps to docker ps -a to show ALL containers (running and stopped)
- Map container status: Up -> active, Exited/Created -> inactive, other -> failed
- Display Docker containers as individual top-level services instead of sub-services
- Each container shown as "docker_{container_name}" in service list
This provides better visibility of all containers and their status directly in the
services panel, making it easier to see stopped containers at a glance.
Updated to version 0.1.172
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
Reordered display sections in system widget:
- Network section now appears after RAM and tmpfs mounts
- Improves logical grouping by placing network info between memory and storage
- Updated to version 0.1.168
Nest IP addresses under physical interface names. Show physical interfaces with status icon on header line. Virtual interfaces show inline with compressed IPs.
Format:
● eno1:
├─ ip: 192.168.30.105
└─ tailscale0: 100.125.108.16
Version bump to 0.1.166
Move network collection from NixOS collector to dedicated NetworkCollector. Add link status detection for physical interfaces (up/down). Group interfaces by physical/virtual, show status icons for physical NICs only. Down interfaces show as Inactive instead of Critical.
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.
Version bump to 0.1.161
Update systemd collector to use sudo for docker ps command to resolve
permission issues when cm-agent user lacks docker group membership.
This ensures Docker containers are properly discovered and displayed
as sub-services under the docker service.
Version: 0.1.160
