# Levels



Flare uses the standard syslog severity levels for logs. Each level has its own method on `flare.logger`. The following levels are available, from most to least severe:

| Method | Description |
| ------ | ----------- |
| `flare.logger.emergency(message, attributes?)` | System is unusable |
| `flare.logger.alert(message, attributes?)` | Action must be taken immediately |
| `flare.logger.critical(message, attributes?)` | Critical conditions |
| `flare.logger.error(message, attributes?)` | Error conditions |
| `flare.logger.warning(message, attributes?)` | Warning conditions |
| `flare.logger.notice(message, attributes?)` | Normal but significant condition |
| `flare.logger.info(message, attributes?)` | Informational messages |
| `flare.logger.debug(message, attributes?)` | Debug-level messages |

```js
flare.logger.debug('Cache miss', { key: 'user:42' });
flare.logger.warning('Retrying request', { attempt: 2 });
flare.logger.critical('Payment provider unreachable');
```

## Setting a minimum level

By default, every level is sent to Flare. Set `minimumLogLevel` to drop anything below a given severity:

```js
flare.configure({
    enableLogs: true,
    minimumLogLevel: 'warning',
});
```

With the example above, only logs at `warning` or above (`warning`, `error`, `critical`, `alert`, `emergency`) are recorded. Calls to `flare.logger.info()` and `flare.logger.debug()` become no-ops.

Logs filtered out by `minimumLogLevel` are never buffered, so they cost nothing beyond the method call.
