Summary

Adds standardized lib_name and lib_version labels to the all_smi_gpu_info metric across all GPU/accelerator platforms. This enables platform-agnostic queries and dashboards while maintaining backward compatibility with existing platform-specific labels.

Changes Made

1. GPU Readers Updated

  • NVIDIA (src/device/readers/nvidia.rs): Added lib_name="CUDA", lib_version=<cuda_version>
  • AMD (src/device/readers/amd.rs): Added lib_name="ROCm", lib_version=<rocm_version>
  • Jetson (src/device/readers/nvidia_jetson.rs): Added lib_name="CUDA", lib_version=<cuda_version>
  • Apple Silicon (src/device/readers/apple_silicon.rs): Added lib_name="Metal", lib_version=<metal_version>

All platform-specific labels (e.g., cuda_version, rocm_version) remain unchanged for backward compatibility.

2. Mock Templates Updated

  • src/mock/templates/nvidia.rs: NVIDIA mock now includes lib_name/lib_version
  • src/mock/templates/amd_gpu.rs: AMD mock now includes lib_name/lib_version
  • src/mock/templates/jetson.rs: Jetson mock now includes lib_name/lib_version
  • src/mock/templates/apple_silicon.rs: Apple Silicon mock now includes lib_name/lib_version

3. Documentation Updated

Added comprehensive section in API.md with:

  • Platform-specific library mappings table
  • PromQL query examples for cross-platform monitoring
  • Backward compatibility notes

Example Output

NVIDIA GPU:

all_smi_gpu_info{gpu="NVIDIA H100 80GB HBM3", instance="node-0001", uuid="...", index="0", 
  driver_version="580.82.07", cuda_version="13.0", 
  lib_name="CUDA", lib_version="13.0"} 1

AMD GPU:

all_smi_gpu_info{gpu="AMD Instinct MI300X 192GB", instance="node-0001", uuid="...", index="0", type="GPU",
  driver_version="30.10.1", rocm_version="7.0.2",
  lib_name="ROCm", lib_version="7.0.2"} 1

Benefits

  1. Unified Queries: Write platform-agnostic PromQL queries

    # Count devices by AI library type
    count by (lib_name) (all_smi_gpu_info)
    
    # Get all CUDA devices version 12+
    all_smi_gpu_info{lib_name="CUDA", lib_version=~"1[2-9].*|[2-9][0-9].*"}
    
    # Alert on outdated ROCm versions (< 7.0)
    all_smi_gpu_info{lib_name="ROCm", lib_version!~"[7-9].*"} == 1
    
  2. Simplified Dashboards: Create single Grafana panels that work across all platforms

  3. Better Cluster Management: Track version consistency across heterogeneous clusters

  4. Backward Compatibility: Existing queries using platform-specific labels continue to work

Testing

  • ✅ All unit tests pass (cargo test)
  • ✅ Build succeeds (cargo build --release)
  • ✅ NVIDIA mock server verified: lib_name="CUDA", lib_version="13.0"
  • ✅ AMD mock server verified: lib_name="ROCm", lib_version="7.0.2"

Test Plan

  • Build project successfully
  • Run all tests successfully
  • Verify NVIDIA mock server includes new labels
  • Verify AMD mock server includes new labels
  • Confirm backward compatibility with existing labels
  • Test with real NVIDIA GPU hardware (if available)
  • Test with real AMD GPU hardware (if available)
  • Verify metrics in Prometheus/Grafana

Resolves #66

…onsistency

Add standardized lib_name and lib_version labels to all_smi_gpu_info metric
across all GPU/accelerator platforms while maintaining backward compatibility
with existing platform-specific labels.

Changes:
- GPU Readers: Add lib_name and lib_version to detail HashMap

- Documentation: Add unified labels section in API.md with:
  - Platform mapping table
  - PromQL query examples for cross-platform monitoring
  - Backward compatibility notes

Benefits:
- Platform-agnostic PromQL queries for AI library monitoring
- Simplified dashboards that work across NVIDIA, AMD, Jetson, and Apple Silicon
- Easy tracking of library versions across heterogeneous clusters
- Backward compatible - existing platform-specific labels remain unchanged

Resolves #66
…ib_name/lib_version fields

- Replace platform-specific CUDA/ROCm version lookups with unified lib_name/lib_version
- Display driver version and AI library (CUDA/ROCm/Metal) for all platforms
- Maintain backward compatibility with legacy data using fallback logic
- Shorten 'Driver:' to 'Drv:' to save space in TUI
- Implements issue #68 alongside #66
For Apple Silicon, strip "Metal " prefix from lib_version to store only
numeric version (e.g., "3" instead of "Metal 3") for consistency with
other platforms' lib_version format.

Modified:
- src/device/readers/apple_silicon.rs: strip_prefix("Metal ")
- src/mock/templates/apple_silicon.rs: lib_version="3"
Replace hardcoded "Metal 3" with actual Metal version detection:
1. Try system_profiler SPDisplaysDataType to parse real Metal version
2. Fall back to macOS version mapping (sw_vers) if needed:
   - macOS 13-15+: Metal 3
   - macOS 12: Metal 2.4
   - macOS 11: Metal 2.3
3. Cache result for performance (existing cache mechanism)

This ensures lib_version reflects the actual Metal version on the system
instead of assuming all Apple Silicon devices run Metal 3.
Update macOS to Metal version mapping to include:
- macOS 26+ (Tahoe): Metal 4
- macOS 15-25 (Sequoia era): Metal 3
- macOS 14 (Sonoma): Metal 3
- macOS 13 (Ventura): Metal 3
- macOS 12 (Monterey): Metal 2.4
- macOS 11 (Big Sur): Metal 2.3

Note: macOS version numbering jumped from 15 to 26 (year-based)
starting with Tahoe, which introduces Metal 4 support.

Add lib_name and lib_version fields to all NPU readers:

- Tenstorrent: lib_name="Luwen", lib_version=ARC firmware version
- Furiosa: lib_name="PERT", lib_version=PERT/firmware version
- Rebellions: lib_name="RBLN-SDK", lib_version=KMD version

This provides consistent AI library identification across all accelerator
types (GPUs and NPUs) for unified monitoring and querying.
Updates the Furiosa NPU reader implementation to comply with the official
furiosa-smi-rs 2025.3.0 API documentation.

Changes:
- Replace Device::all() with list_devices() for device enumeration
- Replace device.get_device_info() with device.device_info()
- Replace single get_performance() call with individual metric methods:
  - device.core_utilization() for utilization metrics
  - device.device_temperature() for temperature
  - device.power_consumption() for power
  - device.governor_profile() for governor settings
  - device.core_frequency() for frequency
- Update DeviceInfo field access to use method calls instead of direct
  field access (serial(), uuid(), arch(), firmware_version(), etc.)
- Use VersionInfo::to_string() for firmware and PERT versions
- Rename create_gpu_info_from_device() to create_gpu_info_from_device_2025()
  to reflect the new API version
- Update lib_version to use info.pert_version().to_string() for accurate
  PERT version reporting

🔍 Security & Performance Review - Phase 1 Complete

✅ Security Analysis Results

1. Command Execution Security ✅ SECURE

  • All command executions use execute_command_default() which includes:
    • Input validation via validate_command() and validate_args()
    • Protection against shell metacharacters (;, &, |, $, backticks, etc.)
    • Path traversal prevention (.. patterns blocked)
    • No direct shell invocations or unsafe string interpolations
  • Risk Level: LOW - Proper security measures in place

2. Error Handling & Panic Safety ✅ GOOD

  • No new unwrap() calls that could cause panics
  • All uses of unwrap_or provide safe default values
  • Proper error propagation with ? operator
  • JSON parsing uses safe error handling patterns
  • Risk Level: LOW - No panic vulnerabilities identified

3. Input Validation ⚠️ MINOR ISSUES FOUND

  • Issue: String parsing with strip_prefix("Metal ") assumes format consistency
  • Location: src/device/readers/apple_silicon.rs:182-184
  • Impact: Could produce unexpected version strings if format changes
  • Priority: LOW - Graceful degradation with fallback to full string

📊 Performance Analysis Results

1. String Parsing Efficiency ⚠️ OPPORTUNITIES IDENTIFIED

  • Multiple string allocations in hot paths:
    • driver_ver.clone() at line 170
    • thermal_level.clone() at line 175
    • Version string manipulations creating new allocations
  • Impact: Minor memory overhead, ~50-100 bytes per GPU read
  • Priority: MEDIUM - Affects monitoring frequency

2. Command Execution Overhead ✅ ACCEPTABLE

  • System calls are properly cached where possible
  • Metal version detection adds 1-2 extra subprocess calls
  • Impact: ~10-20ms additional latency on first read
  • Priority: LOW - Only affects initialization

🐛 Potential Issues Identified

Issue #1: Metal Version Detection Edge Case

Priority: MEDIUM
Location: src/device/readers/apple_silicon.rs:347-359

// macOS version to Metal version mapping
let metal_version = match major {
    26.. => "Metal 4",    // macOS 26+ (Tahoe)
    15..=25 => "Metal 3", // macOS 15-25 (Sequoia era)
    // ...

Problem: Version range 15..=25 may be incorrect. macOS typically increments by 1 yearly.
Recommendation: Verify macOS version numbering scheme and adjust ranges.

Issue #2: Furiosa API Error Messages to stderr

Priority: LOW
Location: src/device/readers/furiosa.rs:246-248, 287-296

eprintln!("Failed to parse memory for process {}: {}", proc.pid, proc.memory);

Problem: Error messages printed to stderr in library code without logging control
Recommendation: Use proper logging framework or return errors to caller

Issue #3: Missing Version Validation

Priority: LOW
Location: Multiple readers
Problem: No validation that extracted version strings are in expected format
Recommendation: Add regex validation for version formats (e.g., \d+\.\d+)

🔄 Next Steps

Continuing with:

  • Deep dive into Furiosa API 2025.3.0 migration compatibility
  • Performance profiling of string operations
  • Edge case testing for version detection logic

Review Progress: 40% Complete
