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

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

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");
