Overview of Performance Monitor
Performance Monitor enables you to monitor your storage system and collect detailed usage and performance statistics. You can view the data in lists and on graphs to identify changes in usage rates and workloads, analyze trends in disk I/O, and detect peak I/O times. For example, if there is a decrease in performance, such as delayed host response times, you can use Performance Monitor to discover the reason for the decrease and determine the actions to take to improve performance.
Performance Monitor collects data about storage system resources such as drives, volumes, and microprocessors as well as statistics about front-end (host I/O) and back-end (drive I/O) workloads. You can perform the following types of monitoring depending on the storage system:
- Data is collected when the Monitoring Switch is set to Enable, and you specify when and how often the data is collected.
Using the Performance Monitor data, you can manage and fine-tune the performance of your storage system using the performance management software products.
