Datadog API Logs

Datadog Logs Submission

Implements log submission and forwarding to Datadog API with a focus on structured logging for enhanced observability. Configures logging to include necessary Datadog fields for correlation with metrics.

TL;DR Checklist

• Use structured logging with JSON format to enable context-rich log entries.
• Inject Datadog-specific fields (dd.trace_id, dd.span_id) during log submission.
• Validate the connection to the Datadog logs endpoint on startup.

Core Workflow

1. Initialize Log Configuration: Set up a logger that outputs in JSON format. Integrate the necessary Datadog fields for tracing. Checkpoint: Test log output to ensure all required fields are present.

2. Inject Datadog Fields: Ensure every log entry includes dd.trace_id and dd.span_id using the ddtrace library. Checkpoint: Confirm the correlation of logs to their corresponding tracing information.

3. Submit Logs to Datadog: Forward the logs in batches to minimize API calls. Ensure that logs are sent with the correct tags reflecting service and environment. Checkpoint: Validate the submission and check for errors after each batch.

Implementation Patterns

Pattern 1: Log Submission Implementation

import logging
import json
import os
from ddtrace import patch

# Patch logging to automatically add Datadog trace IDs
patch(logging=True)

class DatadogLogger:
    def __init__(self):
        logging.basicConfig(level=logging.INFO,
                            format='%(asctime)s	%(levelname)s	%(message)s')

    def log_info(self, message, tags=None):
        log_entry = {"message": message, "tags": tags if tags else []}
        print(json.dumps(log_entry))  # Send to your log forwarding mechanism.

    def log_error(self, message, error, tags=None):
        log_entry = {"message": message, "error": str(error), "tags": tags if tags else []}
        print(json.dumps(log_entry))  # Send to your log forwarding mechanism.

Pattern 2: Error Handling in Log Submission

def handle_logging_error(e):
    logger.error("Logging error occurred: %s", str(e))
    # Implement retry logic or fallback as necessary

Constraints

MUST DO

• Ensure structured logs are submitted in a format that includes key metadata for observability.
• Validate configuration against the logs endpoint during initialization.

MUST NOT DO

• Never send plain text logs without context. Use structured JSON for better observability.
• Do not neglect to include trace IDs for correlation purposes.
