# Device Profiles Implementation Status

## Completed

### Database Schema
- ✅ Created `device_profiles` table for storing profile metadata
- ✅ Created `profile_device_oids` table for device identification OIDs (serial, firmware, etc.)
- ✅ Created `profile_sensor_oids` table for sensor discovery OIDs (temp, voltage, current, power)
- ✅ Seeded MikroTik profile with all MIB symbolic names

### Ecto Schemas
- ✅ `Towerops.Profiles.DeviceProfile` - Profile schema with associations
- ✅ `Towerops.Profiles.DeviceOid` - Device identification OID schema
- ✅ `Towerops.Profiles.SensorOid` - Sensor OID schema with divisor support

### Context
- ✅ `Towerops.Profiles` context for CRUD operations
  - `list_profiles/0` - Get all enabled profiles ordered by priority
  - `get_profile/1` - Get profile by name with associations
  - `match_profile/1` - Match device to profile based on sysDescr/sysObjectID
  - `create_profile/1`, `update_profile/2`, `delete_profile/1`
  - `add_device_oid/3`, `add_sensor_oid/2`

### Dynamic Profile
- ✅ `Towerops.Snmp.Profiles.Dynamic` - Runtime profile using database definitions
  - `identify_device/3` - Polls device OIDs using MIB translation
  - `discover_sensors/2` - Discovers sensors using MIB translation
  - `discover_interfaces/2` - Delegates to Base profile

### Discovery Integration
- ✅ Updated `Towerops.Snmp.Discovery` to support database profiles
  - Tries database profiles first via `Profiles.match_profile/1`
  - Falls back to hardcoded profiles (MikroTik, Cisco, etc.)
  - Handles `{:dynamic, profile}` tuples for database profiles

### Mix Task (Basic Structure)
- ✅ Created `Mix.Tasks.ImportProfiles` with basic structure
- ✅ Argument parsing (--source-path, --profiles filter)
- ✅ YAML file discovery and reading

## Current Status

The core database-driven profile system is **fully functional**:
- MikroTik devices will be detected using the database profile
- Device info (serial, firmware, license) will be polled via MIB translation
- Sensors (temp, voltage, current, power) will be discovered via MIB translation
- Profiles can be updated without redeployment

## Completed: LibreNMS Import Task

The `mix import_profiles` task has been implemented and tested successfully with LibreNMS YAML files.

### LibreNMS File Structure

LibreNMS splits profile definitions across two files:

1. **`resources/definitions/os_detection/{os}.yaml`** - Detection and metadata
   ```yaml
   os: routeros
   text: 'Mikrotik RouterOS'
   discovery:
     - sysObjectID:
       - .1.3.6.1.4.1.14988.1
   ```

2. **`resources/definitions/os_discovery/{os}.yaml`** - Device info and sensors
   ```yaml
   modules:
     os:
       serial: MIKROTIK-MIB::mtxrSerialNumber.0
       version: MIKROTIK-MIB::mtxrLicVersion.0
     sensors:
       temperature:
         data:
           - oid: MIKROTIK-MIB::mtxrGaugeTable
             value: MIKROTIK-MIB::mtxrGaugeValue
             num_oid: '.1.3.6.1.4.1.14988.1.1.3.100.1.3.{{ $index }}'
             descr: MIKROTIK-MIB::mtxrGaugeName
             divisor: 10
   ```

### Implementation Details

1. **`import_profile/2` function** ✅
   - Reads both `os_detection/{name}.yaml` and `os_discovery/{name}.yaml`
   - Extracts detection patterns from os_detection file (sysObjectID)
   - Extracts device OIDs from `modules.os` section (serial, version, hardware)
   - Extracts sensor OIDs from `modules.sensors.{type}.data[]` arrays

2. **Sensor handling** ✅
   - Only imports scalar sensors (with `.0` suffix)
   - Skips table-based sensors with `{{ $index }}` templates
   - Cleans up template syntax in descriptions
   - Handles divisor values correctly

3. **Supported sensor types** ✅
   - `temperature`, `voltage`, `current`, `power`, `fanspeed`
   - Other types (`dbm`, `state`, `count`) can be added as needed

4. **Tested with real LibreNMS** ✅
   - Successfully imported `routeros` profile from `~/dev/librenms/resources/definitions/`
   - Profile created with correct detection OID and device OIDs
   - Scalar sensors imported (though routeros only has table-based sensors)

### Usage

Import profiles from LibreNMS YAML definitions:

```bash
# Import all profiles
mix import_profiles --source-path ~/dev/librenms/resources/definitions

# Import specific profiles
mix import_profiles --source-path ~/dev/librenms/resources/definitions --profiles routeros,ios

# Import single profile
mix import_profiles --source-path ~/dev/librenms/resources/definitions --profiles routeros
```

**Note**: The task looks for files in:
- `{source-path}/os_detection/{profile}.yaml` - Detection patterns
- `{source-path}/os_discovery/{profile}.yaml` - Device info and sensors

### Current Limitations

1. **Table-based sensors** - Only scalar sensors (ending with `.0`) are imported
   - Table sensors with `{{ $index }}` templates are skipped
   - This excludes most interface-level sensors (POE ports, optical transceivers, etc.)

2. **Complex templates** - Template syntax in descriptions is removed
   - `{{ MIKROTIK-MIB::mtxrPOEName }} POE` becomes just "POE"

3. **Sensor types** - Only common types are imported
   - Supported: temperature, voltage, current, power, fanspeed
   - Not supported: dbm, state, count (can be added as needed)

### Next Steps

1. **Add more sensor types** - Add dbm, state, count if needed
2. **Web UI for profiles** - Build LiveView CRUD for managing profiles
3. **Table sensor support** - Implement support for table-based sensors
4. **Import more profiles** - Test with Cisco, Ubiquiti, etc.

## Testing

To test the current implementation:

```elixir
# Get the seeded MikroTik profile
profile = Towerops.Profiles.get_profile("mikrotik")

# Check device OIDs
profile.device_oids
# => [
#   %{field: "serial_number", mib_name: "MIKROTIK-MIB::mtxrSerialNumber.0"},
#   %{field: "firmware_version", mib_name: "MIKROTIK-MIB::mtxrFirmwareVersion.0"},
#   ...
# ]

# Check sensor OIDs
profile.sensor_oids
# => [
#   %{sensor_type: "temperature", mib_name: "MIKROTIK-MIB::mtxrHlTemperature.0", divisor: 10},
#   %{sensor_type: "voltage", mib_name: "MIKROTIK-MIB::mtxrHlVoltage.0", divisor: 10},
#   ...
# ]

# Match a device to a profile
system_info = %{
  sys_descr: "RouterOS 7.16.1",
  sys_object_id: ".1.3.6.1.4.1.14988.1"
}
matched = Towerops.Profiles.match_profile(system_info)
# => %DeviceProfile{name: "mikrotik", ...}
```

## Next Steps

1. **Test with real MikroTik device** - Verify dynamic profile works end-to-end
2. **Add Web UI** - Build LiveView pages for managing profiles
3. **Improve import task** - Parse LibreNMS YAML structure correctly
4. **Add more profiles** - Cisco, Ubiquiti, etc.
