Performance, capacity, and configuration troubleshooting

Learn more about the features that IBM Storage Insights and IBM Storage Insights Pro provide to troubleshoot the performance, capacity, and configuration of your storage environment.

IBM Storage Insights Pro subscribers can use the performance information that is collected, analyzed, and presented in summary views, table views, and trending charts to identify performance anomalies such as performance bottlenecks and slow response times. This includes performance information for switches, fabrics, and hosts.

To help you detect performance issues before they impact the storage environments, you can complete these actions:

Use alert policies to manage alert definitions for groups of resources.
Define alerts for individual resources, such as storage systems, hosts., switches, and fabrics. If multiple alerts are triggered by the same violations, only one consolidated alert is displayed.
Define alerts for storage resources that are assigned to applications and general groups.
Identify whether the performance of their storage systems that run IBM Storage Virtualize comply with best practice guidelines for key performance indicators.
Use the performance trending charts to identify and investigate performance issues.

Specify email addresses to be notified when alerts are triggered. Alerts can be triggered by changes to the attributes, capacity, and performance of resources. When the warning threshold for a storage resource is exceeded, you are notified so that you can act before the situation becomes critical.

Tip: To help you define warning and critical thresholds you are provided with recommended values for threshold values that do not vary much between environments.

To detect performance anomalies, you can use the key performance indicator charts to compare the metric values for the storage systems that run IBM Storage Virtualize with the best practice values that were established by the historical analysis of storage environments. If the performance metric values for your storage systems exceed the best practice value or range of values, you can investigate further and determine whether you need to take remedial action.

Storage systems that run IBM Storage Virtualize: IBM SAN Volume Controller, IBM Storwize family, IBM Storage FlashSystem V9000 storage systems, and to the IBM Storage Virtualize software-only solution.

In the performance table views and performance trending charts, you can investigate the performance of your storage systems and their internal resources. You can investigate and compare the performance of storage systems and investigate the performance of internal resources such as disks and volumes.

In the performance trending charts, you can select the performance metrics that you want to use to compare the performance of storage resources. If you detect an issue, you can change the time range to determine whether the issue recurs, or occurs at a specific time or on a specific day or days.
