This functionality is enabled by default, +but can be disabled by setting `VLLM_CONFIGURE_LOGGING=0` when running vLLM. + +If `VLLM_CONFIGURE_LOGGING` is enabled and no value is given for +`VLLM_LOGGING_CONFIG_PATH`, vLLM will use built-in default configuration to +configure the root vLLM logger. By default, no other vLLM loggers are +configured and, as such, all vLLM loggers defer to the root vLLM logger to make +all logging decisions. + +If `VLLM_CONFIGURE_LOGGING` is disabled and a value is given for +`VLLM_LOGGING_CONFIG_PATH`, an error will occur while starting vLLM. + +### `VLLM_LOGGING_CONFIG_PATH` + +`VLLM_LOGGING_CONFIG_PATH` allows users to specify a path to a JSON file of +alternative, custom logging configuration that will be used instead of vLLM's +built-in default logging configuration. The logging configuration should be +provided in JSON format following the schema specified by Python's [logging +configuration dictionary +schema](https://docs.python.org/3/library/logging.config.html#dictionary-schema-details). + +If `VLLM_LOGGING_CONFIG_PATH` is specified, but `VLLM_CONFIGURE_LOGGING` is +disabled, an error will occur while starting vLLM. + + +## Examples + +### Example 1: Customize vLLM root logger + +For this example, we will customize the vLLM root logger to use +[`python-json-logger`](https://github.com/madzak/python-json-logger) to log to +STDOUT of the console in JSON format with a log level of `INFO`. + +To begin, first, create an appropriate JSON logging configuration file: + +**/path/to/logging_config.json:** + +```json +{ + "formatters": { + "json": { + "class": "pythonjsonlogger.jsonlogger.JsonFormatter" + } + }, + "handlers": { + "console": { + "class" : "logging.StreamHandler", + "formatter": "json", + "level": "INFO", + "stream": "ext://sys.stdout" + } + }, + "loggers": { + "vllm": { + "handlers": ["console"], + "level": "INFO", + "propagate": false + } + }, + "version": 1 +} +``` + +Next, install the `python-json-logger` package if it's not already installed: + +```bash +pip install python-json-logger +``` + +Finally, run vLLM with the `VLLM_LOGGING_CONFIG_PATH` environment variable set +to the path of the custom logging configuration JSON file: + +```bash +VLLM_LOGGING_CONFIG_PATH=/path/to/logging_config.json \ + python3 -m vllm.entrypoints.openai.api_server \ + --max-model-len 2048 \ + --model mistralai/Mistral-7B-v0.1 +``` + + +### Example 2: Silence a particular vLLM logger + +To silence a particular vLLM logger, it is necessary to provide custom logging +configuration for the target logger that configures the logger so that it won't +propagate its log messages to the root vLLM logger. + +When custom configuration is provided for any logger, it is also necessary to +provide configuration for the root vLLM logger since any custom logger +configuration overrides the built-in default logging configuration used by vLLM. + +First, create an appropriate JSON logging configuration file that includes +configuration for the root vLLM logger and for the logger you wish to silence: + +**/path/to/logging_config.json:** + +```json +{ + "formatters": { + "vllm": { + "class": "vllm.logging.NewLineFormatter", + "datefmt": "%m-%d %H:%M:%S", + "format": "%(levelname)s %(asctime)s %(filename)s:%(lineno)d] %(message)s" + } + }, + "handlers": { + "vllm": { + "class" : "logging.StreamHandler", + "formatter": "vllm", + "level": "INFO", + "stream": "ext://sys.stdout" + } + }, + "loggers": { + "vllm": { + "handlers": ["vllm"], + "level": "DEBUG", + "propagage": false + }, + "vllm.example_noisy_logger": { + "propagate": false + } + }, + "version": 1 +} +``` + +Finally, run vLLM with the `VLLM_LOGGING_CONFIG_PATH` environment variable set +to the path of the custom logging configuration JSON file: + +```bash +VLLM_LOGGING_CONFIG_PATH=/path/to/logging_config.json \ + python3 -m vllm.entrypoints.openai.api_server \ + --max-model-len 2048 \ + --model mistralai/Mistral-7B-v0.1 +``` + + +### Example 3: Disable vLLM default logging configuration + +To disable vLLM's default logging configuration and silence all vLLM loggers, +simple set `VLLM_CONFIGURE_LOGGING=0` when running vLLM. This will prevent vLLM +for configuring the root vLLM logger, which in turn, silences all other vLLM +loggers. + +```bash +VLLM_CONFIGURE_LOGGING=0 \ + python3 -m vllm.entrypoints.openai.api_server \

PR Checklist (Click to Expand)

Thank you for your contribution to vLLM! Before submitting the pull request, please ensure the PR meets the following criteria. This helps vLLM maintain the code quality and improve the efficiency of the review process.

PR Title and Classification

Only specific types of PRs will be reviewed. The PR title is prefixed appropriately to indicate the type of change. Please use one of the following:

  • [Bugfix] for bug fixes.
  • [CI/Build] for build or continuous integration improvements.
  • [Doc] for documentation fixes and improvements.
  • [Model] for adding a new model or improving an existing model. Model name should appear in the title.
  • [Frontend] For changes on the vLLM frontend (e.g., OpenAI API server, LLM class, etc.)
  • [Kernel] for changes affecting CUDA kernels or other compute kernels.
  • [Core] for changes in the core vLLM logic (e.g., LLMEngine, AsyncLLMEngine, Scheduler, etc.)
  • [Hardware][Vendor] for hardware-specific changes. Vendor name should appear in the prefix (e.g., [Hardware][AMD]).
  • [Misc] for PRs that do not fit the above categories. Please use this sparingly.

Note: If the PR spans more than one category, please include all relevant prefixes.

Code Quality

The PR need to meet the following code quality standards:

  • We adhere to Google Python style guide and Google C++ style guide.
  • Pass all linter checks. Please use format.sh to format your code.
  • The code need to be well-documented to ensure future contributors can easily understand the code.
  • Include sufficient tests to ensure the project to stay correct and robust. This includes both unit tests and integration tests.
  • Please add documentation to docs/source/ if the PR modifies the user-facing behaviors of vLLM. It helps vLLM user understand and utilize the new features or changes.

Notes for Large Changes

Please keep the changes as concise as possible. For major architectural changes (>500 LOC excluding kernel/data/config/test), we would expect a GitHub issue (RFC) discussing the technical design and justification. Otherwise, we will tag it with rfc-required and might not go through the PR.

What to Expect for the Reviews

The goal of the vLLM team is to be a transparent reviewing machine. We would like to make the review process transparent and efficient and make sure no contributor feel confused or frustrated. However, the vLLM team is small, so we need to prioritize some PRs over others. Here is what you can expect from the review process:

  • After the PR is submitted, the PR will be assigned to a reviewer. Every reviewer will pick up the PRs based on their expertise and availability.
  • After the PR is assigned, the reviewer will provide status update every 2-3 days. If the PR is not reviewed within 7 days, please feel free to ping the reviewer or the vLLM team.
  • After the review, the reviewer will put an action-required label on the PR if there are changes required. The contributor should address the comments and ping the reviewer to re-review the PR.
  • Please respond to all comments within a reasonable time frame. If a comment isn't clear or you disagree with a suggestion, feel free to ask for clarification or discuss the suggestion.

Thank You

Finally, thank you for taking the time to read these guidelines and for your interest in contributing to vLLM. Your contributions make vLLM a great tool for everyone!
