Magento 2: How to override default logger?

Question

I want all my log files to be send to a certain server by using this snippet in a custom module

use Monolog\Logger;
use Monolog\Handler\SyslogUdpHandler;
$log = new Logger('Test');
$log->pushHandler(new SyslogUdpHandler("MyLogServer", 5000));
$log->addError("ERRORRRRRR::");

Is there a common place where I can register this new logger, so that every new log is processed by this handler and not written into files?

Thanks

Try to set preference for LoggerInterface in VendorName/ModuleName/etc/di.xml. This will make your logger default systemwide:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Psr\Log\LoggerInterface" type="VendorName\ModuleName\Model\CustomLogger" />
</config>

Note that CustomLogger must implement LoggerInterface in this case.
