$MAGENTO_CLOUD_RELATIONSHIPS variable to retrieve the RabbitMQ connection details and login credentials.
質問 # 48
Which log file would help a developer to investigate 503 errors caused by traffic or insufficient server resources on an Adobe Commerce Cloud project?
- A. cloud.log
- B. access.log
- C. mysql-slow.log
正解：B
解説：
Explanation
The access.log file stores the information about the requests and responses that occur on the web server, such as the IP address, timestamp, request URI, response code, and referer URL1. By checking the access.log file, a developer can identify the requests that resulted in 503 errors and the possible causes of those errors, such as traffic spikes, insufficient server resources, or misconfiguration1.
To check the access.log file on an Adobe Commerce Cloud project, a developer can use the following command in the CLI:
grep -r "\" 50 [0-9]" /path/to/access.log
This command will search for any lines in the access.log file that contain a response code starting with 50, which indicates a server error1. The developer can then compare the timestamps of those lines with the exception.log and error.log files to find more details about the errors1.
Alternatively, if the error has occurred in the past and the access.log file has been rotated (compressed and archived), the developer can use the following command in the CLI (Pro architecture only):
zgrep "\" 50 [0-9]" /path/to/access.log.<rotation ID>.gz
This command will search for any lines in the compressed access.log file that contain a response code starting with 501. The rotation ID is a number that indicates how many times the log file has been rotated. For example, access.log.1.gz is the most recent rotated log file, and access.log.10.gz is the oldest rotated log file1.

- A. $.mage
- B. $.ui
- C. $.widget

Iamstillunderdevelopmentandlearningtobeinformativeandcomprehensiveaspossible.
Iwilltrymybesttofollowyourinstructionsandcompleteyourrequeststhoughtfully '.mage.extend()` function is used to extend an existing set of widget resources in Magento. It takes two arguments: the name of the widget and an object that contains the new properties and methods.
For example, the following code extends the existing Magento accordion widget:
$.mage.extend('mage.accordion', {
// New property
myCustomProperty: 'value',
// New method
myCustomMethod: function() {
// Do something custom
}
});
The new widget will have the myCustomProperty property and the myCustomMethod() method in addition to the properties and methods of the original accordion widget.
The $.widget() function is still used to create new widgets in Magento, but it is not used to extend existing widgets.
