# 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`

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

### 2. Enable in Sentry.init()
```javascript
Sentry.init({
  dsn: "YOUR_DSN",
  enableLogs: true,
});
```

### 3. Console capture (optional)
```javascript
integrations: [
  Sentry.consoleLoggingIntegration({ levels: ["warn", "error"] }),
],
```

### 4. Use structured logging
```javascript
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 |
|---------|-------------|---------|
| Pino | `Sentry.pinoIntegration()` | 10.18.0+ |
| Winston | `Sentry.createSentryWinstonTransport()` | 9.13.0+ |
| Consola | `Sentry.createConsolaReporter()` | 10.12.0+ |

## Python Setup

### 1. Verify SDK version
```bash
pip show sentry-sdk | grep Version
```

### 2. Enable in init()
```python
sentry_sdk.init(
    dsn="YOUR_DSN",
    enable_logs=True,
)
```

### 3. Stdlib logging capture (optional)
```python
from sentry_sdk.integrations.logging import LoggingIntegration
integrations=[LoggingIntegration(sentry_logs_level=logging.WARNING)]
```

### 4. Use structured logging
```python
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
```python
from sentry_sdk.integrations.loguru import LoguruIntegration
integrations=[LoguruIntegration(sentry_logs_level=LoggingLevels.WARNING.value)]
```

## Ruby Setup

### 1. Verify SDK version
```bash
bundle show sentry-ruby
```

### 2. Enable in init
```ruby
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
```ruby
Sentry.logger.info("User logged in")
Sentry.logger.error("Payment failed. Order: %{order_id}", order_id: "456")
```

## Log Filtering

### JavaScript
```javascript
beforeSendLog: (log) => log.level === "info" ? null : log,
```

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

## 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 |
