Where do you check to ensure the metadata application is running?

The correct answer is the PADR.log. This log file is essential for reviewing the status and activity of the metadata application. It contains detailed logs that provide insights into the application's functioning, including any errors or warnings that may indicate issues. By checking the PADR.log, administrators can confirm whether the application is operating as expected or if there are any problems that need to be addressed.

The other options, while relevant to different aspects of the CyberArk environment, do not specifically serve the purpose of checking the operational status of the metadata application. For instance, the PADR.ini file is primarily a configuration file that might inform you about settings and parameters but does not provide real-time status information. The Vault activity monitor allows you to view the interactions and access patterns within the vault but does not focus on the operational status of the metadata application. Similarly, the System Performance Dashboard offers metrics on system performance but is not tailored toward monitoring the specific status of the metadata application. Therefore, the PADR.log is the most appropriate resource for verifying that the application is running properly.
