--- name: checking-system-health-7e0c483fc757 description: >- Provides comprehensive pre-flight verification for acquisition systems. Orchestrates MCP tools to check network mounts, hardware connectivity, and system configuration. Use before running acquisition sessions or when troubleshooting system issues. --- # System Health Check Provides comprehensive pre-flight verification for acquisition systems by orchestrating multiple MCP tools to validate network storage, hardware connectivity, and system configuration. --- ## MCP Server Requirements All four MCP servers must be running to perform a complete system health check. | Server | Start Command | Tools Used | |-------------------------|--------------------|----------------------------------------------| | sl-experiment | `sl-get mcp` | Mount checks, Zaber discovery, projects | | sl-shared-assets | `sl-configure mcp` | Working directory, credentials, templates | | ataraxis-video-system | `axvs mcp` | Camera discovery, video requirements, CTI | | ataraxis-comm-interface | `axci-mcp` | Microcontroller discovery, MQTT broker | If any MCP server is unavailable, inform the user which server is needed and provide the start command. --- ## Complete Verification Workflow Copy this checklist when performing a system health check: ```text System Health Check Progress: - [ ] Phase 1: Configuration prerequisites verified - [ ] Phase 2: Network storage mounts accessible - [ ] Phase 3: Hardware discovery completed - [ ] Phase 4: Video system requirements verified - [ ] Phase 5: Configuration validation passed ``` ### Phase 1: Configuration Prerequisites | Check | Tool | Expected Result | |------------------------------|-------------------------------------|-------------------------------------| | Working directory set | `get_working_directory_tool` | Returns valid path | | System config exists | `check_system_mounts_tool` | Returns system name | | Task templates directory set | `get_task_templates_directory_tool` | Returns valid path to Unity configs | **Task templates directory** must point to the `sl-unity-tasks/Assets/InfiniteCorridorTask/Configurations/` folder. If not configured, use `set_task_templates_directory_tool(directory)` to set it before running experiments. ### Phase 2: Network Storage Mounts | Check | Tool | Expected Result | |-----------------------|----------------------------|----------------------------| | All mounts accessible | `check_system_mounts_tool` | All paths show "OK" status | If any mount fails, use `check_mount_accessibility_tool(path)` for detailed diagnostics on specific paths. **Interpreting mount results:** - `Exists: No` indicates the path does not exist. Check mount configuration in `/etc/fstab` or systemd mount units. - `Mount: No` indicates the path exists but is not a mount point. This may indicate a local directory is being used instead of network storage. - `Writable: No` indicates the path exists but write test failed. Check permissions or mount options (uid, gid, file_mode, dir_mode). ### Phase 3: Hardware Discovery | Check | Tool | Expected Result | |---------------------------|----------------------------------------|------------------------------------| | Cameras detected | `list_cameras` | Shows expected camera indices | | Microcontrollers detected | `list_microcontrollers` | Shows ACTOR, SENSOR, ENCODER ports | | Zaber motors detected | `get_zaber_devices_tool` | Shows all motor groups and axes | | MQTT broker reachable | `check_mqtt_broker("127.0.0.1", 1883)` | Connection successful | ### Phase 4: Video System Requirements | Check | Tool | Expected Result | |-----------------------|------------------------------|----------------------------------------| | Runtime requirements | `check_runtime_requirements` | FFMPEG available, GPU detected | | CTI file (Harvesters) | `get_cti_status` | CTI file configured (if using GeniCam) | ### Phase 5: Configuration Validation | Check | Tool | Expected Result | |--------------------|--------------------------------------------------|------------------------------| | Projects exist | `get_projects_tool` | Lists expected projects | | Zaber config valid | `validate_zaber_configuration_tool(port, index)` | Status: VALID for each motor | --- ## Quick Health Check For a rapid pre-session check, run these tools in sequence: 1. `check_system_mounts_tool()` verifies all storage is accessible 2. `list_cameras()` confirms cameras are connected 3. `list_microcontrollers()` confirms microcontrollers are connected 4. `get_zaber_devices_tool()` confirms motors are connected 5. `check_mqtt_broker("127.0.0.1", 1883)` confirms Unity communication ready If all pass, the system is ready for acquisition. --- ## Troubleshooting Guide ### Mount Failures | Symptom | Likely Cause | Resolution | |-------------------------|-----------------------|---------------------------------------------------------| | Path does not exist | Mount not configured | Add entry to `/etc/fstab` or create systemd mount unit | | Exists but not mount | Local directory used | Check mount status with `mount | grep path` | | Not writable | Permission issue | Check mount options (uid, gid, file_mode, dir_mode) | | Stale mount | Network disruption | Remount: `sudo umount -l /path && sudo mount /path` | ### Hardware Not Detected | Symptom | Likely Cause | Resolution | |--------------------------|--------------------------|-------------------------------------------------------| | Camera not in list | USB disconnected | Check physical connection | | Wrong camera index | USB enumeration changed | Re-run discovery after reboot | | Microcontroller missing | Port conflict | Check `ls /dev/ttyACM*` and ensure no other process | | Zaber not responding | Power off | Verify motor power supply is on | ### MQTT Connection Failed | Symptom | Likely Cause | Resolution | |---------------------|---------------------|----------------------------------------------------| | Connection refused | Broker not running | Start Mosquitto: `sudo systemctl start mosquitto` | | Timeout | Wrong IP/port | Verify Unity PC IP address in configuration | --- ## Post-Check Actions After completing the health check: 1. **All checks pass**: System is ready for `/acquisition-system-setup` configuration or session execution. 2. **Mount failures**: Resolve OS-level mount issues before proceeding. 3. **Hardware missing**: Check physical connections and re-run discovery. 4. **Configuration invalid**: Use `/acquisition-system-setup` to update configuration. --- Source attribution: David-Li0406 Original project: https://github.com/David-Li0406/meta-skill-evloving/blob/ca3a335628981df10c36e00cb9850df2c247ab9a/skill-flow/data/skills-refined-36k/skillsmp/checking-system-health/SKILL.md License: Apache-2.0 License information: https://www.apache.org/licenses/LICENSE-2.0 Original upstream instructions; downloaded from Dave AI. ## Upstream license notice Apache License Version 2.0, January 2004 http://www.apache.org/licenses/ TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 1.
