Add export and import functionality for device SNMP profiles:
Export (local):
- New mix task: mix export_profiles --librenms-path ~/dev/librenms --output profiles.json
- Exports all profiles to JSON format
- Can filter specific profiles with --profiles flag
Import (production):
- New API endpoint: POST /api/v1/admin/profiles/import
- Requires superuser authentication via browser session
- Processes imports in background via Exq worker (maintenance queue)
- Returns job ID for tracking
New modules:
- Mix.Tasks.ExportProfiles - Export profiles to JSON
- ProfileImportWorker - Background job for importing profiles
- ProfilesController - API endpoint for bulk import
- RequireSuperuser plug - Restricts access to superusers
- Importer.import_profile_from_data/2 - Import from data structures
This enables bulk profile management without SSH access to production.
Fixed three compile warnings by removing unreachable error handling:
1. Dynamic.discover_sensors/2 always returns {:ok, sensors}, never errors
- Removed unreachable error clause in discovery.ex
- Updated spec to reflect actual return type
2. parse_detection_rule/2 always returns {:ok, :processed}
- Simplified create_detection_rules/2 to use Enum.each instead of reduce_while
- Removed unreachable error handling in caller
3. import_all_from_directory/2 always returns {:ok, %{...}}
- Removed unreachable error clause in Mix task
- Simplified to direct pattern match
All code now compiles without warnings.
Replace all references with generic terms:
- 'external YAML files' instead of specific project names
- 'device profiles' for database-stored definitions
- 'imported OID definitions' for sensor configurations
This makes the codebase vendor-neutral and focused on the
internal implementation rather than external dependencies.
