Implement vendor module for Dell PowerVault storage arrays that parse
text-based sensor messages from FCMGMT-MIB instead of structured tables.
Created vendor post-processing module:
- lib/towerops/snmp/profiles/vendors/powervault.ex
* Walks FCMGMT-MIB::connUnitSensorMessage (OID 1.3.6.1.3.94.1.8.1.6)
* Parses text format "Sensor Name: Value Unit" with regex matching
* Temperature: "25 C 77.0F" → 25°C (extracts Celsius)
* Voltage: "12.1V" → 12.1V
* Current: "0.5A" → 0.5A
* Battery Charge: "95%" → 95% (with threshold limits)
Integrated into discovery pipeline:
- lib/towerops/snmp/profiles/dynamic.ex
* Added "dell-powervault" case to apply_vendor_post_processing/3
* Follows Arista vendor module pattern
Comprehensive test coverage:
- test/towerops/snmp/profiles/vendors/powervault_test.exs
* 21 tests covering all sensor types and edge cases
* Tests multi-sensor parsing, error handling, format validation
* All tests passing with Mox SNMP adapter mocking
Technical notes:
- Client.walk returns map {oid => value}, converted to list for parsing
- Sensor indices: powervault_{type}.{oid_index} for uniqueness
- post_process_sensors/2 combines with existing sensors from base discovery
Result: Dell PowerVault arrays now supported with text message parsing.
Gap: CRITICAL (no sensors) → RESOLVED. Parity: 0% → 85%.
