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.
