How to view error logs? not in bitrix/modules

Answer 1

What kind of errors do you want to track?
Debug to file:

It is possible to record all queries to the database and their execution time in a separate debug file, for this it is necessary to initialize the $DBDebugToFile variable with the value "true" in the /bitrix/php_interface/dbconn.php file.
In the new core, the following functions are responsible for this: Bitrix\Main\Diag\Debug::dumpToFile and Bitrix\Main\Diag\Debug::writeToFile.
Manual addition via addMessage2Log:

// В файле /bitrix/php_interface/dbconn.php определить константу LOG_FILENAME, в которой задать путь к лог-файлу
define("LOG_FILENAME", $_SERVER["DOCUMENT_ROOT"]."/log.txt");

In the future, any arrays, texts can be sent to this file using

AddMessage2Log("Произвольный текст сообщения или массив", "my_module_id(необязательно)");
