FileTarget日志中忽略跟踪信息。

即使traceLevel设置为大于0，跟踪数据也不会写入日志文件。

这有助于在开发环境中获得更干净的日志。

安装

安装此扩展的首选方式是通过composer。

运行以下命令之一：

php composer.phar require --prefer-dist roslov/yii2-compact-file-target "*"

或添加以下内容到您的composer.json文件的require部分：

"roslov/yii2-compact-file-target": "*"

用法

扩展安装后，只需在代码中通过以下方式使用它：

让我们假设您有如下配置

return [
    'bootstrap' => ['log'],
    'components' => [
        'log' => [
            'targets' => [
                [
                    'class' => 'yii\log\FileTarget',
                    'levels' => ['info'],
                    'categories' => ['analytics'],
                    'logVars' => [],
                ],
            ],
        ],
    ],
];

在Yii::info($text, 'analytics');之后，您的日志将输出如下：

2017-10-30 12:11:41 [172.18.0.1][43][-][info][analytics] User 123 updated.
    in /var/www/html/components/analytics/Analytics.php:110
    in /var/www/html/components/analytics/Analytics.php:75
    in /var/www/html/modules/api/v2/behaviors/EventTracker.php:40
2017-10-30 12:11:42 [172.18.0.1][43][-][info][analytics] Notification sent to user 123.
    in /var/www/html/components/analytics/Analytics.php:110
    in /var/www/html/components/analytics/Analytics.php:75
    in /var/www/html/modules/api/v2/behaviors/ActivityTracker.php:85
2017-10-30 12:11:55 [172.18.0.1][43][-][info][analytics] User 456 logged out.
    in /var/www/html/components/analytics/Analytics.php:110
    in /var/www/html/components/analytics/Analytics.php:41
    in /var/www/html/modules/api/v2/behaviors/ActivityTracker.php:57

如果您只是记录事件，可能不需要任何跟踪信息。

因此，您可以更改class从yii\log\FileTarget到roslov\log\CompactFileTarget

return [
    'bootstrap' => ['log'],
    'components' => [
        'log' => [
            'targets' => [
                [
                    'class' => 'roslov\log\CompactFileTarget',
                    'levels' => ['info'],
                    'categories' => ['analytics'],
                    'logVars' => [],
                ],
            ],
        ],
    ],
];

在这种情况下，日志看起来会更干净。

2017-10-30 12:11:41 [172.18.0.1][43][-][info][analytics] User 123 updated.
2017-10-30 12:11:42 [172.18.0.1][43][-][info][analytics] Notification sent to user 123.
2017-10-30 12:11:55 [172.18.0.1][43][-][info][analytics] User 456 logged out.
