- -## Sampling debug logs - -Sampling allows you to set your Logger Log Level as DEBUG based on a percentage of your concurrent/cold start invocations. You can set a sampling value of `0.0` to `1` (100%) using either `sample_rate` parameter or `POWERTOOLS_LOGGER_SAMPLE_RATE` env var. - -This is useful when you want to troubleshoot an issue, say a sudden increase in concurrency, and you might not have enough information in your logs as Logger log level was understandably set as INFO. - -Sampling decision happens at the Logger class initialization, which only happens during a cold start. This means sampling may happen significantly more or less than you expect if you have a steady low number of invocations and thus few cold starts. - - - If you want Logger to calculate sampling on every invocation, then please open a feature request. -

- - -## Migrating from other Loggers - -If you're migrating from other Loggers, there are few key points to be aware of: **Service parameter**, **Inheriting Loggers**, **Overriding Log records**, and **Logging exceptions**. - -### service parameter - -Service is what defines what the function is responsible for, or part of (e.g payment service), and the name of the Logger. - -For Logger, the `service` is the logging key customers can use to search log operations for one or more functions - For example, **search for all errors, or messages like X, where service is payment**. - -### inheriting Loggers - -> Python Logging hierarchy happens via the dot notation: `service`, `service.child`, `service.child_2`. - -For inheritance, Logger uses a `child=True` parameter along with `service` being the same value across Loggers. - -For child Loggers, we introspect the name of your module where `Logger(child=True, service="name")` is called, and we name your Logger as **{service}.{filename}**. - -A common issue when migrating from other Loggers is that `service` might be defined in the parent Logger (no child param), and not defined in the child Logger: - -```python:title=incorrect_logger_inheritance.py -# app.py -import my_module -from aws_lambda_powertools import Logger - -logger = Logger(service="payment") # highlight-line -... - -# my_module.py -from aws_lambda_powertools import Logger - -logger = Logger(child=True) # highlight-line -``` - -In this case, Logger will register a Logger named `payment`, and a Logger named `service_undefined`. The latter isn't inheriting from the parent, and will have no handler, thus no message being logged to standard output. - -This can be fixed by either ensuring both has the `service` value as `payment`, or simply use the environment variable `POWERTOOLS_SERVICE_NAME` to ensure service value will be the same across all Loggers when not explicitly set. - -### overriding Log records - -You might want to continue to use the same date formatting style, or override `location` to display the `package.function_name:line_number` as you previously had. - -Logger allows you to either change the format or suppress the following keys altogether at the initialization: `location`, `timestamp`, `level`, `xray_trace_id`, and `datefmt` - -```python -from aws_lambda_powertools import Logger - -# override default values for location and timestamp format -logger = Logger(stream=stdout, location="[%(funcName)s] %(module)s", datefmt="fake-datefmt") # highlight-line - -# suppress location key -logger = Logger(stream=stdout, location=None) # highlight-line -``` - -Alternatively, you can also change the order of the following log record keys via the `log_record_order` parameter: `level`, `location`, `message`, `xray_trace_id`, and `timestamp` - -```python -from aws_lambda_powertools import Logger - -# make message as the first key -logger = Logger(stream=stdout, log_record_order=["message"]) # highlight-line - -# Default key sorting order -logger = Logger(stream=stdout, log_record_order=["level","location","message","timestamp"]) # highlight-line -``` - -Some keys cannot be supressed in the Log records: `sampling_rate` is part of the specification and cannot be supressed; `xray_trace_id` is supressed automatically if X-Ray is not enabled in the Lambda function, and added automatically if it is. - -### logging exceptions - -When logging exceptions, Logger will add a new key named `exception`, and will serialize the full traceback as a string. - -```python:title=logging_an_exception.py -from aws_lambda_powertools import Logger -logger = Logger() - -try: - raise ValueError("something went wrong") -except Exception: - logger.exception("Received an exception") # highlight-line -``` - -
