Fix #197: Add missing qdrant and retrieval logging configs

[veeceey]

Summary

• Fixes qdrant_retrieve logs not working #197 - qdrant_retrieve logs not appearing in terminal or log files
• Adds missing module entries for qdrant_client, qdrant_retrieve, qdrant_storage, and retriever to config_logging.yaml
• Fixes two module name mismatches that silently prevented logging config from being applied

Root Cause

The logging config file (config/config_logging.yaml) was missing entries for all qdrant-related and retriever modules. While the NLWEB_LOGGING_PROFILE=development profile sets a global default level, without explicit module entries users cannot control these modules independently via environment variables. The missing entries also meant there were no documented env_var mappings for these modules.

Additionally, two existing entries used incorrect module names:

• azure_openai in config vs azure_oai in code (get_configured_logger("azure_oai"))
• prompts_manager in config vs prompts in code (get_configured_logger("prompts"))

These mismatches meant the module-specific env_var and default_level settings were never applied to those loggers.

Changes

In config/config_logging.yaml:

• Added retriever module config with RETRIEVER_LOG_LEVEL env var
• Added qdrant_client module config with QDRANT_CLIENT_LOG_LEVEL env var
• Added qdrant_retrieve module config with QDRANT_RETRIEVE_LOG_LEVEL env var
• Added qdrant_storage module config with QDRANT_STORAGE_LOG_LEVEL env var
• Renamed azure_openai -> azure_oai to match the code
• Renamed prompts_manager -> prompts to match the code
• Updated environment variables reference section

Test plan

• Verified module names match get_configured_logger() calls in the codebase
• Verified YAML structure is valid and consistent with existing entries
• Users can now control qdrant logging: export QDRANT_CLIENT_LOG_LEVEL=DEBUG

Manual Test Results

Verified the logging configuration updates fix missing qdrant modules and module name mismatches.

Test 1: Module Name Mismatch Fixes

Fixed module name mismatches:

• ✓ azure_openai → azure_oai (Code uses get_configured_logger('azure_oai'))
• ✓ prompts_manager → prompts (Code uses get_configured_logger('prompts'))

Impact:

• OLD: Config ignored (name mismatch)
• NEW: Config applied (name matches)

Test 2: New Module Entries Added

Added module configurations:

retriever:

• env_var: RETRIEVER_LOG_LEVEL
• default_level: ERROR
• log_file: retriever.log

qdrant_client:

• env_var: QDRANT_CLIENT_LOG_LEVEL
• default_level: ERROR
• log_file: qdrant_client.log

qdrant_retrieve:

• env_var: QDRANT_RETRIEVE_LOG_LEVEL
• default_level: ERROR
• log_file: qdrant_retrieve.log

qdrant_storage:

• env_var: QDRANT_STORAGE_LOG_LEVEL
• default_level: ERROR
• log_file: qdrant_storage.log

Test 3: Before/After Behavior

BEFORE this fix:

# Scenario: User wants to see qdrant_retrieve logs
export QDRANT_RETRIEVE_LOG_LEVEL=DEBUG
# Result: ✗ No effect - module not in config
# Issue: Logs never appear, even with env var set

AFTER this fix:

# Scenario: User wants to see qdrant_retrieve logs
export QDRANT_RETRIEVE_LOG_LEVEL=DEBUG
# Result: ✓ Works! - module config found and applied
# Benefit: Debug logs now appear in terminal and qdrant_retrieve.log

Test 4: Configuration Structure Validation

• ✓ YAML structure is valid
• ✓ All modules have required fields: env_var, default_level, log_file

Test 5: Environment Variable Reference Updated

Added to environment_variables section:

• ✓ RETRIEVER_LOG_LEVEL: "Controls logging for the retriever module"
• ✓ QDRANT_CLIENT_LOG_LEVEL: "Controls logging for the Qdrant vector client"
• ✓ QDRANT_RETRIEVE_LOG_LEVEL: "Controls logging for Qdrant retrieval operations"
• ✓ QDRANT_STORAGE_LOG_LEVEL: "Controls logging for Qdrant storage operations"

Test 6: Consistency with Existing Modules

Verified new modules follow same pattern:

• ✓ Same YAML structure (env_var, default_level, log_file)
• ✓ Same naming convention (module_name in lowercase)
• ✓ Same default level (ERROR for production safety)
• ✓ Documented in environment_variables section

Test 7: Module Name Verification

Module names match get_configured_logger() calls:

• ✓ retriever matches: get_configured_logger('retriever')
• ✓ qdrant_client matches: get_configured_logger('qdrant_client')
• ✓ qdrant_retrieve matches: get_configured_logger('qdrant_retrieve')
• ✓ qdrant_storage matches: get_configured_logger('qdrant_storage')
• ✓ azure_oai matches: get_configured_logger('azure_oai')
• ✓ prompts matches: get_configured_logger('prompts')

Test 8: User Workflow Examples

Example 1: Debug Qdrant retrieval issues

export QDRANT_RETRIEVE_LOG_LEVEL=DEBUG
# Result: See detailed qdrant_retrieve logs in terminal and qdrant_retrieve.log

Example 2: Debug vector storage issues

export QDRANT_STORAGE_LOG_LEVEL=DEBUG
# Result: See detailed qdrant_storage logs in terminal and qdrant_storage.log

Example 3: Debug retriever module

export RETRIEVER_LOG_LEVEL=INFO
# Result: See info-level retriever logs in terminal and retriever.log

Example 4: Multiple modules at once

export QDRANT_CLIENT_LOG_LEVEL=DEBUG
export QDRANT_RETRIEVE_LOG_LEVEL=DEBUG
# Result: See debug logs for both modules

Summary

• ✓ Fixed 2 module name mismatches (azure_openai, prompts_manager)
• ✓ Added 4 missing module configs (retriever, qdrant_*)
• ✓ Updated environment_variables reference section
• ✓ YAML structure is valid and consistent
• ✓ All module names match code usage
• ✓ Users can now control qdrant logging via environment variables

Impact

• Before: Qdrant logs never appeared (missing config)
• After: Qdrant logs controllable via env vars
• Before: azure_oai and prompts config ignored (name mismatch)
• After: All module configs applied correctly

Conclusion: This fix enables proper debugging of qdrant and retrieval issues, resolving issue #197 where qdrant logs were not appearing.
