Predefined reports

Predefined reports

You can view the following types of predefined reports:

Reports about the capacity and relationships of your resources

Reports about the capacity and relationships of servers, hypervisors, network-attached storage systems, storage virtualizers, storage systems, storage resource groups, groups, fabrics, and switches. Use these reports to analyze the capacity and relationships of resources. For example, to show the current space statistics for a pool on a storage system, run the Pools Capacity report. To show the pools that are related to a storage system, run the Storage Resource Relationships Summary report.

Reports about performance

Reports about the performance of your monitored resources. You can view reports about storage systems, components of storage systems, switches, and switch ports. Use these reports to analyze the performance of resources. For example, to find out which are the most active volumes on a storage system over a specified period, run the Most Active Volumes report. To view details about the performance of a volume over a specified period, run a report such as the Performance of One Volume report.

Restrictions:

• Performance data is collected at intervals. An interval represents the number of minutes over which samples of performance data are averaged. Data that is collected at certain intervals is automatically consolidated, or rolled up, to higher intervals. For example, data collected at 1-minute intervals is consolidated into 5-minute data. When you create a performance report in the Cognos Analytics reporting tool, the smallest interval for the sample data is 5 minutes. The data collected at 1-minute intervals is not available in the Cognos Analytics reporting tool to avoid performance problems.
• Performance reports are not available for the following storage systems:
  • IBM Storage FlashSystem 900
  • IBM Storage Scale
  • Dell EMC Unity
  • Hitachi VSP
  • NetApp storage systems running ONTAP 9
  • Pure FlashArray//M and FlashArray//X storage systems
  To view performance metrics for those storage systems, use the IBM Spectrum Control GUI. For more information, see Monitoring the performance of resources.

Reports about historical capacity

Reports that include the historical information about the capacity of your storage systems, pools, and volumes. Use these reports to determine whether more storage resources are required. For example, to show how space is used over a specified period on volumes on storage systems, run the Volumes Historical Capacity report. You can also use these reports to analyze future storage requirements for your environment.

Reports about storage tiering

Reports that include information about the workload activity of these resources: managed disk (MDisk) groups, virtual disks (VDisks) in MDisk groups, VDisks in storage resource groups, and VDisks in storage virtualizers. Use these reports to determine the best storage-tier configuration for your environment.
