    'performance_monitor' => [
        'logger_output_enable' => 1,
        'logger_output_verbose' => 0,
    ]
]

Use 0 or 1 as the value to enable or disable. Both logger_output_enable and logger_output_verbose default to 0.

The option logger_output_enable enables outputting performance metrics to the logger using debug method of logger. The option logger_output_verbose adds additional metrics.
