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)
- Dell enterprise servers (iDRAC) not supported (CRITICAL)
Next Steps: Implement Tier 1 critical network switch sensor profiles.

docs: Phase 2 vendor sensor analysis complete (Cisco/Juniper/Arista)
Complete comprehensive sensor discovery analysis for top 3 enterprise network
vendors. Results show excellent parity with specific actionable improvements
identified for Arista EOS.
Vendor Analysis Results:
- Cisco IOS/XE/XR/NX-OS: 95% parity ✅ Production ready
- All critical sensors via ENTITY-SENSOR-MIB + YAML profiles
- PoE, HSRP, module status, StackWise, redundancy covered
- Minor gap: cellular modem sensors (rare devices, low impact)
- Juniper JunOS: 100% parity ✅ Perfect
- junos.yaml files byte-for-byte identical between systems
- 30+ sensor types, 38+ OIDs, 10 MIBs covered
- Optical, BER, CD, DGD, Q-factor, SNR, RPM all included
- Arista EOS: 85% parity ⚠️ Improvements needed
- Base ENTITY-SENSOR-MIB coverage complete
- CRITICAL: DOM power shown as watts instead of dBm
- CRITICAL: Missing ARISTA-ENTITY-SENSOR-MIB thresholds
- MINOR: No smart grouping (SFPs/PSUs/Platform)
- ADVANTAGE: Towerops discovers CPU/Memory/Uptime + PSU/Fan state
Identified Fixes (Arista):
1. DOM power conversion (2-3 hrs) - watts→dBm for optical sensors
2. Arista thresholds (4-6 hrs) - enable alerting with warn/critical limits
3. Smart grouping (2-3 hrs) - organize sensors by type
4. Description cleanup (1-2 hrs) - remove redundant text
Documentation Created:
- cisco-ios-comparison.md: ENTITY-SENSOR-MIB analysis, YAML profiles
- juniper-junos-comparison.md: Complete MIB inventory, identical files
- arista-eos-comparison.md: Gap analysis with implementation plan
- PHASE2-VENDOR-ANALYSIS.md: Executive summary and recommendations
Total: 50+ sensor types analyzed, 15+ MIBs documented, 50+ platforms verified
Recommendation: Cisco and Juniper are production ready. Arista needs critical
fixes (1 day effort) for full production readiness.

docs: complete LibreNMS parity audit and add missing OS profiles
Complete comprehensive audit comparing Towerops device detection and sensor
discovery against LibreNMS (~/dev/librenms). Results show excellent parity:
Detection Parity: 100%
- Added 2 missing OS detection profiles (conteg-pdu, microsens-g6)
- Now 786 profiles total (matches LibreNMS exactly)
- Priority vendors verified: MikroTik, Ubiquiti (100% identical)
Sensor Discovery Parity: 95%+
- MikroTik: All 22 sensor tables covered identically
- Ubiquiti: Identical YAML-based discovery
- Towerops has index template enhancement (prevents deduplication bugs)
Audit Documentation:
- detection-algorithm.md: LibreNMS 2-pass detection analysis
- towerops-detection.md: Towerops 4-phase detection analysis
- vendor-detection-comparison.csv: Priority vendor comparison
- librenms-sensors.md: LibreNMS sensor architecture (360+ modules)
- EXECUTIVE-SUMMARY.md: Key findings and recommendations
- IMPLEMENTATION-STATUS.md: Phase 1 completion status
Towerops Architectural Advantages:
- 4-phase detection (vs 2-phase) - clearer separation
- Rust NIF MIB resolution - microsecond lookups vs milliseconds
- ETS pre-resolved cache - 95%+ hit rate, no runtime overhead
- Index templates - prevents sensor deduplication issues
- Substring OID matching - handles firmware variations
Conclusion: Towerops is a drop-in replacement for LibreNMS detection/discovery
with same or better capabilities plus performance improvements.
