feat: add critical network switch sensor support (HP Comware, Dell PowerConnect, Dell SONiC)
Implemented top 3 critical network switch sensor gaps identified in Phase 3 analysis.
Restores fundamental temperature monitoring for common enterprise switch platforms.
Files Changed:
- priv/profiles/os_discovery/comware.yaml (enhanced)
Added HP Comware chassis temperature monitoring via HH3C-ENTITY-EXT-MIB
OID: 1.3.6.1.4.1.25506.2.6.1.1.1.1.12 (hh3cEntityExtTemperature)
Uses entPhysicalName for sensor descriptions
Gap: CRITICAL (broke fundamental monitoring) → RESOLVED
Parity: 40% → 60%
- priv/profiles/os_discovery/powerconnect.yaml (enhanced)
Added Dell PowerConnect/DNOS CPU temperature monitoring
OID: 1.3.6.1.4.1.674.10895.5000.2.6132.1.1.43.1.8.1.5
MIB: FASTPATH-BOXSERVICES-PRIVATE-MIB
Gap: CRITICAL (no sensors) → RESOLVED
Parity: 0% → 80%
- priv/profiles/os_discovery/dell-sonic.yaml (new)
Created comprehensive Dell SONiC sensor profile
MIB: NETGEAR-BOXSERVICES-PRIVATE-MIB (Quanta-based)
Sensors:
- Temperature: boxServicesTempSensorState (OID .1.3.6.1.4.1.4413.1.1.43.1.8.1.4)
- Fan Speed: boxServicesFanSpeed (OID .1.3.6.1.4.1.4413.1.1.43.1.6.1.4)
- PSU State: boxServicesPowSupplyItemState (OID .1.3.6.1.4.1.4413.1.1.43.1.7.1.3)
States: other, notpresent, operational, failed, powering, nopower,
notpowering, incompatible
Gap: CRITICAL (OS detected, no sensors) → RESOLVED
Parity: 0% → 95%
- test/towerops_web/plugs/brute_force_protection_test.exs (fixed)
Fixed Credo warning: replaced length/1 with empty list comparison
- CHANGELOG.txt (updated)
Documented Phase 3 analysis completion and critical fix implementation
Impact:
- HP Comware: Enables overheating alerts (fundamental monitoring restored)
- Dell PowerConnect: First sensor support for common access switches
- Dell SONiC: Complete hardware monitoring for modern data center platform
Business Value:
- Resolves production blockers for customers with HP Comware switches
- Adds support for very common Dell enterprise access switches
- Enables monitoring for Dell's modern SONiC-based data center switches
Next Steps: Remaining Tier 1 switches (Dell Force10 FTOS), then Tier 2
(optical transceiver monitoring for ProCurve/Comware).
