Logging and Profiling
=====================

This extension allows logging HTTP requests being sent and profiling their execution.
In order to setup a log target, which can capture all entries related to HTTP requests, you should
use category `yii\httpclient\Transport*`. For example:

```php
return [
    // ...
    'components' => [
        // ...
        'log' => [
            // ...
            'targets' => [
                [
                    'class' => 'yii\log\FileTarget',
                    'logFile' => '@runtime/logs/http-request.log',
                    'categories' => ['yii\httpclient\*'],
                ],
                // ...
            ],
        ],
    ],
];
```

You may also use [HTTP client DebugPanel](topics-debug.md) to see all related logs.

> Attention: since the content of some HTTP requests may be very long, saving it in full inside the logs
  may lead to certain problems. Thus there is the restriction on the maximum length of the request content,
  which will be placed in log. It is controlled by [[\yii\httpclient\Client::contentLoggingMaxSize]].
  Any exceeding content will be trimmed before logging.
