Resolution

Since no logs are being updated, it is possible that there may be an issue with the logback.xml file. The logback.xml file contains configuration settings that determine how Artifactory logs events and messages during runtime.
To proceed, navigate to the $JFROG_HOME/artifactory/var/etc/artifactory directory and inspect the logback.xml file. Here is an example of the directory listing:

drwxr-xr-x.  6 artifactory artifactory  4096 Jan 1 20:08 .
drwxr-xr-x. 13 artifactory artifactory  4096 Jan 1 20:09 ..
-rw-r-----.  1 artifactory artifactory  3251 Jan 1 00:05 artifactory.config.20230323.000514.yml

-rw-r-----.  1 artifactory artifactory  1145 Jan 1 00:03 binarystore.xml

-rw-r-----.  1 artifactory artifactory     0 Jan 1 20:08 logback.xml
-rw-r-----.  1 artifactory artifactory  6242 Jan 1 00:03 mimetypes.xml

From the directory listing, it appears that the logback.xml file has a file size of 0 bytes, indicating that it is empty and has no contents. When the logback.xml file is empty or missing, it means that the logging framework has no configuration to work with, and it may not be able to initialize properly.

Although Artifactory doesn't remove the contents of the logback.xml file, it's possible that the user deleted the file manually or it was overwritten by an empty file due to running an automation script. To determine how the content was erased, you may need to conduct an internal investigation.
To address this issue, you can try the following solutions:

• Locate a backup copy of the logback.xml file.
• Copy the logback.xml file from another Artifactory instance that is currently functioning correctly, ensuring that the versions match.
• Download the Artifactory Linux Archive Installer and extract the logback.xml file from under the artifactory-pro-<VERSION>/app/misc/etc/artifactory directory.

After replacing the file,

Restart Artifactory and the service is now running as expected.
