Features

• Simple structured logging without dependencies on OpenTelemetry
• Batching of logs for better performance
• Customizable configuration through environment variables or code
• Support for Flask and FastAPI web frameworks
• Ability to send logs to a custom endpoint or fallback to console output

Configuration

Configure the logger via environment variables:

# Required for sending logs to a custom endpoint
export SIFT_DEV_ENDPOINT="https://your-log-endpoint.com/logs"
export SIFT_DEV_API_KEY="your-api-key"

# Optional configuration
export SIFT_DEV_SERVICE_NAME="your-service-name"
export SIFT_DEV_SERVICE_INSTANCE_ID="your-instance-id"
export ENV="production"  # or development, staging, etc.

Or configure programmatically:

from sift_dev_logger import configure, SiftDevConfig

# Configure once at application startup
configure(SiftDevConfig(
    service_name="my-service",
    service_instance_id="instance-1",
    endpoint="https://your-log-endpoint.com/logs",
    api_key="your-api-key",
    env="production",
    batch_size=10,  # Number of logs to batch before sending
    batch_delay_millis=5000  # Maximum time to wait before sending a batch
))

Basic Usage

from sift_dev_logger import getLogger

# Get a logger (automatically configured with SiftDevHandler)
logger = getLogger("my_module")

# Log messages with different severity levels
logger.info("This is an informational message")
logger.warning("This is a warning message")
logger.error("This is an error message")

# Log with additional context
logger.info("User logged in", extra={"user_id": "12345", "ip_address": "192.168.1.1"})

# Log with structured data
logger.info("API request completed", extra={
    "request_id": "req-abc-123",
    "duration_ms": 42,
    "status_code": 200,
    "user": {
        "id": "user-123",
        "role": "admin"
    }
})

# Make sure all logs are flushed before application exit
from sift_dev_logger import flush_logs
flush_logs()
