Environment Configuration

This section documents environment variables and configuration options.

Environment Variables

Environment Variable Names

dftracer.python.env.DFTRACER_ENABLE_ENV = "DFTRACER_ENABLE"

str(object=’’) -> str str(bytes_or_buffer[, encoding[, errors]]) -> str

Create a new string object from the given object. If encoding or errors is specified, then the object must expose a data buffer that will be decoded using the given encoding and error handler. Otherwise, returns the result of object.__str__() (if defined) or repr(object). encoding defaults to sys.getdefaultencoding(). errors defaults to ‘strict’.

dftracer.python.env.DFTRACER_INIT_ENV = "DFTRACER_INIT"

str(object=’’) -> str str(bytes_or_buffer[, encoding[, errors]]) -> str

Create a new string object from the given object. If encoding or errors is specified, then the object must expose a data buffer that will be decoded using the given encoding and error handler. Otherwise, returns the result of object.__str__() (if defined) or repr(object). encoding defaults to sys.getdefaultencoding(). errors defaults to ‘strict’.

dftracer.python.env.DFTRACER_LOG_LEVEL_ENV = "DFTRACER_LOG_LEVEL"

str(object=’’) -> str str(bytes_or_buffer[, encoding[, errors]]) -> str

Create a new string object from the given object. If encoding or errors is specified, then the object must expose a data buffer that will be decoded using the given encoding and error handler. Otherwise, returns the result of object.__str__() (if defined) or repr(object). encoding defaults to sys.getdefaultencoding(). errors defaults to ‘strict’.

Logger Setup

dftracer.python.env.setup_stream_logger()[source]

Configuration Examples

Enable DFTracer

export DFTRACER_ENABLE=1

Set Log Level

export DFTRACER_LOG_LEVEL=INFO

Set Initialization Mode

export DFTRACER_INIT=PRELOAD

Checking Configuration

In Python code:

from dftracer.python import (
    DFTRACER_ENABLE,
    DFTRACER_INIT_PRELOAD,
    DFTRACER_LOG_LEVEL
)

if DFTRACER_ENABLE:
    print("DFTracer is enabled")
    print(f"Log level: {DFTRACER_LOG_LEVEL}")
    print(f"Preload mode: {DFTRACER_INIT_PRELOAD}")
