Which of the following best describes the purpose of ArcGIS Server Manager?

ArcGIS Server Manager primarily serves as a web application used for managing your ArcGIS Server site. One of its core functionalities includes providing access to system logs and performance metrics, which are essential for administrators to monitor the health and performance of their GIS services.

By accessing system logs, administrators can troubleshoot issues and maintain the efficiency of the various services running on ArcGIS Server. Performance metrics allow administrators to evaluate resource usage, service uptime, and overall server performance, enabling them to make informed decisions for tuning and optimizing their GIS environment.

While creating custom applications, managing user data privacy, or backing up existing spatial data are important tasks within the overall GIS environment, these activities are outside the primary function of Server Manager. Instead, they typically involve using other tools or features within the ArcGIS platform.
