Monitoring the performance of resources

Edit online

IBM Spectrum Control can collect information about the performance of storage systems and switches. This information includes key performance metrics that can help you measure, identify, and troubleshoot performance issues and bottlenecks in your storage.

You can use the performance monitoring to complete the following tasks:

Measure, compare, and troubleshoot the performance of switches, storage systems, and their internal resources.
Review the alerts that were triggered when the performance if a resource fell outside of a specific range.
Customize views of performance so that you can analyze specific resources and metrics during time ranges that you specify.
View performance information in a chart or table format to help you quickly identify where and when performance issues are occurring. The chart is a visual representation of how the performance of resources trend over time.
Drill down into resources to view detailed information about the performance of internal and related resources. For example, if a SAN Volume Controller is shown in the chart, you can quickly view and compare the performance of its internal and related resources, such as disks, volumes, ports, managed disks, and back-end storage.
Implement server-centric monitoring of SAN resources without requiring a Storage Resource agent. When you add an agentless server, IBM Spectrum Control correlates the server with the known host connections on monitored storage systems. If matches are found, you can view the amount of storage that is assigned to the server, and trace that storage back to the storage system. You can then view details about the internal resources of the related storage system, including performance information.
Export performance information to a CSV file. A CSV file is a file that contains comma-delimited values and can be viewed with a text editor or imported into a spreadsheet application.

Before you begin

Before you can view performance information for resources, you must complete the following tasks:

Add storage systems and switches for monitoring by IBM Spectrum Control.	For information about how to add these resources, see the following topics: Adding storage systems Adding fabrics and switches
Ensure that performance data is being collected for a resource. Typically, data collection is scheduled when resources are added for monitoring.	For information about verifying data collection and scheduling performance monitors, see the following topics: Verifying that a performance monitor is running for a resource Creating performance monitors in IBM Spectrum Control
Define performance alerts to be notified if the performance of a resource falls outside a specified range and might represent a potential problem. When you define a performance alert for a resource, select a specific metric that you want to measure. For example, you can define a threshold that notifies you when the total I/O port rate for a storage system falls outside a specified range.	For information about how to define performance alerts, see Defining alert definitions for performance changes.
