Logging
Browser Client Logging
Client logging generally occurs via JavaScript console.log() and can be accessed using the built-in browser-specific developer tools:
- Blink
- Gecko
- WebKit
Application Server/Backend Logging
Logging is an ongoing work-in-progress but some level of control is available using environment variables. Python Logging log() and print() statements send information to the console. The default level is INFO. Ideally, sensitive data will only be exposed with DEBUG level.
Logging Levels
The following logging levels values are supported:
| Level | Numeric value |
|---|---|
CRITICAL | 50 |
ERROR | 40 |
WARNING | 30 |
INFO | 20 |
DEBUG | 10 |
NOTSET | 0 |
Global
The default global log level of INFO can be overridden with the GLOBAL_LOG_LEVEL environment variable. When set, this executes a basicConfig statement with the force argument set to True within config.py. This results in reconfiguration of all attached loggers:
If this keyword argument is specified as true, any existing handlers attached to the root logger are removed and closed, before carrying out the configuration as specified by the other arguments.
The stream uses standard output (sys.stdout). In addition to all Open-WebUI log() statements, this also affects any imported Python modules that use the Python Logging module basicConfig mechanism including urllib.
For example, to set DEBUG logging level as a Docker parameter use:
--env GLOBAL_LOG_LEVEL="DEBUG"
App/Backend
Some level of granularity is possible using any of the following combination of variables. Note that basicConfig force isn't presently used so these statements may only affect Open-WebUI logging and not 3rd party modules.
| Environment Variable | App/Backend |
|---|---|
AUDIO_LOG_LEVEL | Audio transcription using faster-whisper, TTS etc. |
COMFYUI_LOG_LEVEL | ComfyUI integration handling |
CONFIG_LOG_LEVEL | Configuration handling |
DB_LOG_LEVEL | Internal Peewee Database |
IMAGES_LOG_LEVEL | AUTOMATIC1111 stable diffusion image generation |
LITELLM_LOG_LEVEL | LiteLLM proxy |
MAIN_LOG_LEVEL | Main (root) execution |
MODELS_LOG_LEVEL | LLM model interaction, authentication, etc. |
OLLAMA_LOG_LEVEL | Ollama backend interaction |
OPENAI_LOG_LEVEL | OpenAI interaction |
RAG_LOG_LEVEL | Retrieval-Augmented Generation using Chroma/Sentence-Transformers |
WEBHOOK_LOG_LEVEL | Authentication webhook extended logging |
