What logs and metrics are most useful for Dark launches?

Dark launches are a technique used in software development to release features to a subset of users without making them visible to the entire user base. This approach allows teams to gather insights and make improvements before a full rollout. To effectively monitor dark launches, it's crucial to track specific logs and metrics that can provide valuable insights into user behavior and system performance.

<?php // Example of logging during a dark launch function logDarkLaunch($userIdentifier, $feature, $timestamp) { $logEntry = [ 'user_id' => $userIdentifier, 'feature' => $feature, 'timestamp' => $timestamp, 'status' => 'dark_launch' ]; // Assuming logs are stored in a JSON file file_put_contents('dark_launch_logs.json', json_encode($logEntry) . PHP_EOL, FILE_APPEND); } // Example usage logDarkLaunch('user_123', 'new_feature_A', date('Y-m-d H:i:s')); ?>
