 - ExecTransport supports data delivery through proxy. Specify proxy using [libcurl format](http://curl.haxx.se/libcurl/c/CURLOPT_PROXY.html): <[protocol://][user:password@]proxyhost[:port]>

 ### CurlTransport
 CurlTransport does not require a Stackify agent to be installed and it also sends data directly to Stackify services. It collects log entries in a single batch and sends data using native [PHP cURL](http://php.net/manual/en/book.curl.php) functions. This way is a blocking one, so it should not be used on production environments. To configure CurlTransport you need to pass environment name and API key (license key):

 ### AgentTransport
 
 AgentTransport does not require additional configuration in your PHP code because all data is passed to the [Stackify agent](http://support.stackify.com/hc/en-us/articles/205419575). The agent must be installed on the same machine. Local TCP socket on port 10515 is used, so performance of your application is affected minimally.
 ```php
 use Stackify\Log\Standalone\Logger;
 
-$logger = new Logger('appname.com');
+$logger = new Logger('application_name', 'environment_name');
 ```
 
 You will need to enable the TCP listener by checking the "PHP App Logs (Agent Log Collector)" in the server settings page in Stackify. See [Log Collectors Page](http://support.stackify.com/hc/en-us/articles/204719709) for more details.

 ## Troubleshooting
 
 If transport does not work, try looking into ```vendor\stackify\logger\src\Stackify\debug\log.log``` file (if it is available for writing). Errors are also written to global PHP [error_log](http://php.net/manual/en/errorfunc.configuration.php#ini.error-log).
