Yii2log output to file and database

Yii2log output to file and database edit config/web. php

First, log must be enabled.

'bootstrap' => [    'log'],

[File]

'components' => [    'log' => [        'targets' => [            [                'class' => 'yii\log\FileTarget',                'exportInterval' => 1,            ],        ],    ],

Default output to runtime/logs/app. log

Note that webserver or console users must have the permission to write the file

[Database]

'log' => [    'targets' => [        [            'class' => 'yii\log\DbTarget',            'levels' => ['error', 'warning', 'trace'],        ]    ]],

The {% log} table of the database corresponding to the db component is output by default.

Run the following command in the yii2 directory to generate the corresponding table schema

./yii migrate --migrationPath=@yii/log/migrations/

Note that the configuration in config/console. php must be the same as that in web. php. Otherwise, the command cannot be executed successfully.

You can also configure different log modes based on different environments.

'components' => [    'log' => [        'traceLevel' => YII_ENV == 'dev' ? 3 : 0,        'targets' => [            [                'class' => 'yii\log\DbTarget',                'levels' => YII_DEBUG ? ['error', 'warning', 'trace'] : ['error'],            ],            [                'class' => 'yii\log\FileTarget',                'levels' => YII_DEBUG ? ['error', 'warning', 'trace'] : ['error', 'warning'],            ],        ],    ],],
