A developer is concerned about a virtual machine's CPU usage over the past month. How can an administrator show the CPU usage over this time period to the developer?

The best way for an administrator to show the CPU usage of a virtual machine over a month-long period is by accessing the Monitor tab and selecting Overview. The Overview section typically provides a graphical representation of historical performance data, such as CPU usage, memory usage, disk I/O, and network traffic, thus enabling the developer to see trends and analyze usage patterns over the desired timeframe.

This functionality is particularly useful because it aggregates data over periods, allowing users to visualize spikes, drops, and overall trends in performance metrics. This is crucial for understanding how the virtual machine has performed over the past month, rather than focusing on real-time data or summarized displays that might not provide the historical depth required.

In contrast, while the Summary tab may present useful information about the current state of the VM, it does not typically provide historical data over extended time frames, limiting the developer's ability to assess trends effectively. Similarly, the Events section would show notifications or incidents related to the VM but would lack the detailed performance metrics integral to understanding CPU usage over time.
