I have enabled the profiler in order to find out which events are triggered during order creation and processing.
php bin/magento dev:profiler:enable csvfile But it is alway overwriting
var/log/profiler.csv On each request.
How can I keep all profiler output across requests?
If you need to output a request per file and you can not modify the vendor folder, you can extend in your own module the standard Csvfile class:
<?php namespace Vendor\Module\Output; class Csvfile extends \Magento\Framework\Profiler\Driver\Standard\Output\Csvfile { /** * Parses file path * * @param array|null $config * @return string */ protected function _parseFilePath(array $config = null) { $result = parent::_parseFilePath($config); return str_replace('.csv', "-".date('Ymd-His')."-".uniqid('', true).".csv", $result); } } Then you can launch the profiler with:
php bin\magento dev:profiler:enable "\\Vendor\\Module\\Output\\Csvfile" Now the profiler will output each request in a different var/log/profile-yyyymmdd-hhmmss-rand.csv file.
A temporary are to change this is to edit this line:
vendor/magento/framework/Profiler/Driver/Standard/Output/Csvfile.php:41 To
public function __construct(array $config = null) { parent::__construct($config); # change this line, append uniqid() $this->_filePath = $this->_parseFilePath($config) . uniqid('', true); $this->_delimiter = isset($config['delimiter']) ? $config['delimiter'] : ','; $this->_enclosure = isset($config['enclosure']) ? $config['enclosure'] : '"'; } Of course this is a core patch and only for temporary use.
