Setup Sentry Logging

Configure Sentry's structured logging feature.

Invoke This Skill When

• User asks to "setup Sentry logging" or "capture logs in Sentry"
• User wants to integrate logging libraries (Pino, Winston, Loguru) with Sentry
• User asks about Sentry.logger or sentry_sdk.logger

Important: The SDK versions, API names, and code samples below are examples. Always verify against docs.sentry.io before implementing, as APIs and minimum versions may have changed.

Quick Reference

Platform	Min SDK	Enable Flag	Logger API
JavaScript	9.41.0+	enableLogs: true	Sentry.logger.*
Python	2.35.0+	enable_logs=True	sentry_sdk.logger.*
Ruby	5.24.0+	config.enable_logs = true	Sentry.logger.*

JavaScript Setup

1. Verify SDK version

grep -E '"@sentry/(nextjs|react|node|browser)"' package.json

2. Enable in Sentry.init()

Sentry.init({
  dsn: "YOUR_DSN",
  enableLogs: true,
});

3. Console capture (optional)

integrations: [
  Sentry.consoleLoggingIntegration({ levels: ["warn", "error"] }),
],

4. Use structured logging

Sentry.logger.info("User logged in", { userId: "123" });
Sentry.logger.error("Payment failed", { orderId: "456", amount: 99.99 });

// Template literals (creates searchable attributes)
Sentry.logger.info(Sentry.logger.fmt`User ${userId} purchased ${productName}`);

Third-party integrations

Library	Integration	Min SDK
Consola	Sentry.createConsolaReporter()	10.12.0+
Console capture	Sentry.consoleLoggingIntegration()	10.13.0+

Python Setup

1. Verify SDK version

pip show sentry-sdk | grep Version

2. Enable in init()

sentry_sdk.init(
    dsn="YOUR_DSN",
    enable_logs=True,
)

3. Stdlib logging capture (optional)

from sentry_sdk.integrations.logging import LoggingIntegration
integrations=[LoggingIntegration(sentry_logs_level=logging.INFO)]

4. Use structured logging

from sentry_sdk import logger as sentry_logger

sentry_logger.info("User logged in: {user_id}", user_id="123")
sentry_logger.error("Payment failed", order_id="456", amount=99.99)

Loguru integration

from sentry_sdk.integrations.loguru import LoguruIntegration
integrations=[LoguruIntegration(sentry_logs_level=LoggingLevels.INFO.value)]

Ruby Setup

1. Verify SDK version

bundle show sentry-ruby

2. Enable in init

Sentry.init do |config|
  config.dsn = "YOUR_DSN"
  config.enable_logs = true
  config.enabled_patches << :logger  # Optional: capture stdlib Logger
end

3. Use structured logging

Sentry.logger.info("User logged in")
Sentry.logger.error("Payment failed. Order: %{order_id}", order_id: "456")

Log Filtering

JavaScript

beforeSendLog: (log) => log.level === "info" ? null : log,

Python

def before_send_log(log, hint):
    return None if log["severity_text"] == "info" else log

Verification

After enabling logs, emit a test log and check the Sentry Logs dashboard (Explore > Logs):

Sentry.logger.info("Sentry logging test");

Troubleshooting

Issue	Solution
Logs not appearing	Verify SDK version, check enableLogs/enable_logs is set
Too many logs	Use beforeSendLog to filter, reduce captured levels
Console not captured	Add consoleLoggingIntegration to integrations array
