An organization expects a large influx of users who use the standard analysis tools in...

When users perform standard analysis tasks in the portal Map Viewer, the hosting server executes geoprocessing operations that are computationally intensive. These operations require significant CPU resources. Monitoring CPU utilization helps ensure that the server can handle the increased load without performance degradation.​

While disk activity and network utilization are important, they are less directly impacted by standard analysis tasks compared to CPU usage. Therefore, CPU utilization is the primary resource to monitor in this scenario.​
