Which tool is commonly used to analyze the performance of Exchange servers?

Performance Monitor, often referred to as PerfMon, is the correct tool for analyzing the performance of Exchange servers due to its capability to provide detailed insights into various performance metrics. This tool allows administrators to track real-time data and historical trends by collecting and observing performance counters associated with different Exchange components.

PerfMon can monitor critical aspects such as CPU usage, memory consumption, disk activity, and application response times, which are essential for maintaining optimal server performance. It also allows for the customization of monitoring sessions, where specific counters related to Exchange, such as mailbox database performance or mail flow statistics, can be observed.

While Task Manager provides a snapshot of current system performance, it lacks the depth and long-term analysis capabilities that PerfMon offers. Windows Event Viewer is primarily focused on logging events and alerts rather than performance metrics, making it less suitable for performance analysis. Exchange Logs can provide information regarding transactions and server activities but do not offer a comprehensive view of performance in the way that Performance Monitor does. Thus, Performance Monitor is the ideal choice for monitoring Exchange server performance comprehensively.
