What is one benefit of creating an application performance policy in OnCommand Insight?

Creating an application performance policy in OnCommand Insight primarily provides the benefit of setting thresholds on anomaly scores. This capability is essential for monitoring application performance effectively. By establishing these thresholds, organizations can quickly identify and respond to performance issues as they arise. The thresholds act as a benchmark, allowing for the detection of deviations from expected performance levels. This proactive approach helps maintain optimal application performance and can significantly reduce downtime or disruptions caused by unforeseen issues.

In contrast, the other options, while valuable in their own right, do not fully capture the primary focus of application performance policies. Forecasting performance requirements for storage planning is more about anticipating future needs rather than monitoring current performance. Reserving storage capacity for performance issues and dynamically allocating capacity as requirements change also relate to resource management but do not address the specific monitoring aspect that the anomaly score thresholds provide. Thus, the establishment of thresholds for anomaly scores is a crucial aspect of maintaining and ensuring application performance within the environment.
