audit: Phase 3 - HP/Aruba and Dell sensor analysis complete
Completed comprehensive sensor discovery analysis for HP/Aruba and Dell platforms.
Identified critical gaps in network switch monitoring.

Files Added:
- docs/librenms-audit/sensors/hp-aruba-comparison.md
  Analyzed 6 HP/Aruba platforms (ProCurve, Comware, hpblmos, ArubaOS, CX, Instant On)
  - ProCurve: 60% parity (missing transceiver metrics)
  - Comware: 40% parity (CRITICAL - missing temperature + transceivers)
  - hpblmos: 0% parity (CRITICAL - no sensor profile)
  - ArubaOS-CX: 100% parity (EXCELLENT - exceeds LibreNMS)
  - ArubaOS: 100% parity (controller platform)
  - Instant On: 100% parity (AP platform)

- docs/librenms-audit/sensors/dell-comparison.md
  Analyzed 11 Dell platforms (OS10, rPDU, UPS, OME-M, Compellent, PowerVault,
  PowerConnect, Force10, SONiC, Quanta, Servers)
  - Excellent: OS10, rPDU, OME-M, Compellent (100% parity)
  - Critical gaps: PowerConnect, Force10, SONiC, PowerVault, Servers (0% parity)
  Network switches severely underserved compared to infrastructure/storage

- docs/librenms-audit/PHASE3-VENDOR-EXPANSION.md
  Executive summary with implementation priorities and effort estimates
  - Tier 1: Critical network switches (8-12 hours)
  - Tier 2: Optical monitoring (4-6 hours)
  - Tier 3: Storage/compute (7-10 hours)
  - Tier 4: Blade chassis (5-7 hours)
  Total: 26-38 hours for full parity

Key Findings:
- Modern platforms excellent (Aruba CX, Dell OS10)
- Network switches need urgent attention (HP Comware, Dell PowerConnect/FTOS/SONiC)
- HP Comware missing fundamental temperature monitoring (BLOCKING)
- Dell PowerConnect/DNOS/Force10/SONiC missing all sensors (CRITICAL)

Implementation Recommendations

Priority 1 - Critical (Immediate)

  1. Comware temperature sensors (2-3 hours)

    • Add hh3cEntityExtTemperature discovery
    • Enables hardware temperature monitoring and alerting
    • Affects all HP Comware switches (common enterprise platform)
  2. hpblmos sensor support (4-6 hours)

    • Implement temperature, power, and state discovery
    • Enables monitoring for BladeSystem/Moonshot chassis

Priority 2 - High (Short Term)

  1. ProCurve transceiver metrics (2-3 hours)

    • Add hpicfXcvrInfoTable discovery
    • Enables optical monitoring for fiber uplinks
    • Common deployment scenario
  2. Comware transceiver metrics (2-3 hours)

    • Add hh3cTransceiverInfoTable discovery
    • Completes Comware sensor coverage

Priority 3 - Medium (Nice to Have)

  1. Review Comware power metrics alignment
  2. Validate ProCurve PoE power sensor implementation

Parity Target After Fixes

  • ProCurve: 60% → 100% (after transceiver addition)
  • Comware: 40% → 95% (after temperature/transceiver addition)
  • hpblmos: 0% → 80% (after basic sensor addition)
  • ArubaOS: 100% (current)
  • CX: 100% (current - already excellent)
  • Instant On: 100% (current)

Conclusion

Overall Status: ⚠️ Needs Work on Legacy Platforms

Key Achievements:

  • Aruba ArubaOS-CX: Excellent coverage (exceeds LibreNMS)
  • ArubaOS: Good parity for controller platform
  • ProCurve: Good chassis monitoring (fans, PSU, PoE)

Critical Needs:

  • ⚠️ Comware: Missing fundamental temperature monitoring
  • ⚠️ hpblmos: No sensor support at all
  • ⚠️ ProCurve/Comware: Missing transceiver optical monitoring

Recommendation: Implement Comware temperature sensors (Priority 1) first to restore fundamental monitoring capability, then add transceiver support for both ProCurve and Comware platforms.
