Log Levels

Control log verbosity

Control the verbosity of your logging output with Logixlysia’s log level system.

Available Levels

Log levels follow a hierarchy from most to least verbose:

DEBUG > INFO > WARNING > ERROR

When you set a log level, all higher levels will also be logged. For example, setting the level to WARNING will log both WARNING and ERROR messages.

Configuration

Single Level

logixlysia({
  config: {
    logFilter: {
      level: 'ERROR'
    }
  }
})

Multiple Levels

logixlysia({
  config: {
    logFilter: {
      level: ['INFO', 'ERROR']
    }
  }
})

Environment-based

logixlysia({
  config: {
    logFilter: {
      level: process.env.NODE_ENV === 'production' 
        ? ['ERROR', 'WARNING']
        : ['DEBUG', 'INFO', 'WARNING', 'ERROR']
    }
  }
})

Pino Log Levels

When using Pino integration, you can also configure Pino’s log levels:

logixlysia({
  config: {
    pino: {
      level: 'debug' // 'fatal', 'error', 'warn', 'info', 'debug', 'trace'
    }
  }
})

Best Practices

• Development: Use DEBUG for detailed debugging
• Staging: Use INFO for normal operation
• Production: Use WARNING or ERROR for normal operation
• Monitoring: Set up alerts for ERROR level

Example Configurations

Development

logFilter: {
  level: ['DEBUG', 'INFO', 'WARNING', 'ERROR']
}

Production

logFilter: {
  level: ['WARNING', 'ERROR']
}

Monitoring

logFilter: {
  level: ['ERROR']
}
