# Create performance reports

Unisphere supports the creation, management, and running of performance reports.

## About this task

To create a performance report:

## Steps

1. Select a storage system.
2. Select Performance > Reports.
3. Click Create.
4. In the General section, enter a report Name.
5. Optional: Enter a report Description.
6. Select the System.
7. Select the Time Frame.
   If you select Custom, the Custom Time Selection dialog box displays for custom start and end times.

   The Last Interval option is available only for the Diagnostic type. This option runs a report at each diagnostic interval on the following categories:

   - System
   - Director
   - Port
   - Storage group

   In addition, every hour the system runs a cleanup job to remove Last Interval reports that are older than one hour.

8. From the Generated Time Zone menu, select the time zone to apply to times in the report.
9. Select a Format.
10. For XML or CSV reports, add one or more queries to the report. Each of these reports must have at least one query.
    For more information about creating queries, see Create queries using the Create Query wizard. Queries can also be edited (see Modify queries using the Modify Query wizard) or deleted.

    | NOTE: If the report contains multiple queries involving volumes and disks, the report is saved to this location: install_dir/SMAS/report/SPA/runnow

11. Optional: In the Set Schedule section, select the Run every x hours starting check box and configure values for each of the following options:
    - First run time—The first run time is continually adjusted relative to the current time and the report execution interval. For example, if the time is set to 3am, but the current time is 4am and the Time Frame is set to Last 4 Hours, then the value of the first run time is changed to 7am.
    - Day(s) to run
    - Retain for (days)
    The value of x in Run every x hours starting check box depends on the value that is selected for Time Frame.
12. Optional: In the Enable Email section, specify the report email options, if email notifications have been configured.
13. Click OK.
