    I have tried to get $wpdb->queries from my plugin to print all wp queries. But $wpdb->queries return null. When I check var_dump($wpdb), it return last_query and num_queries is not 0. How can the $wpdb->queries return null but the last_query and num_quries is filled? and how I can get result for the $wpdb->queries from my plugin?

    I believe you need SAVEQUERIES defined as true in wp-config.php for wpdb::queries to be populated.

    Note that there is a sizable performance hit in doing this. It’s not something you’d want in place for every single request.

    Another avenue of investigation would be to examine the source code of the Query Monitor plugin and see how it gathers its query information.

    It works. My Bad. I defined the config SAVEQUERIES on the bottom line, not between the custom value lines. Thank you for the advice
