Custom reports about performance

You can use the optional Cognos Analytics reporting tool to create custom performance reports. Performance reports can contain detailed information about the performance of monitored resources, and some of the properties of those resources.

The resources for which you can create performance reports are storage systems and their components, storage virtualizers and their components, and switches and switch ports. You can add statistics for volumes, back-end arrays, caches, ports, port errors, and other statistics to performance reports. For example, you can add key statistics to a report to create and generate a performance chart for a specific volume of a storage system.

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.
