You can identify key metrics that are outside
of a standard range for resources that run IBM Storage Virtualize by using the key performance
indicators charts.
Before you begin
Before you view the performance of your resources that run IBM Storage Virtualize, ensure that performance data was
collected for those systems during the time ranges that you want to analyze. IBM
Spectrum Control uses performance monitors to collect data so
that you can measure the performance of storage systems and switches. To
verify that performance monitors were run, follow the instructions in Verifying that a performance monitor is running for a resource.
About this task
In this documentation, IBM Storage Virtualize is used to refer collectively to
IBM SAN Volume
Controller, IBM Storage Virtualize for Public Cloud, IBM Storage Virtualize as Software
Only, and IBM
Storwize storage systems, and to IBM
Storage FlashSystem devices that run IBM Storage Virtualize.
Restriction: Key performance indicators are
provided only for IBM Storage FlashSystem 9100 from the
IBM
Storage FlashSystem family. Key performance
indicators are not provided for file storage in Storwize V7000 Unified storage systems.
Procedure
-
To select a storage system, choose one of the following options from the menu bar:
| Resource |
Menu bar |
|---|
| Block storage systems |
|
| File storage systems |
|
-
From the list of storage systems that are displayed, right-click the resource that you want to
view and click View Details.
For example, select a SAN Volume Controller or a
Storwize storage system on the
Block Storage Systems page, or select a Storwize V7000 Unified storage system on the File
Storage Systems page.
-
In the General section of the resource
details page, click Performance.
The key performance indicators charts are displayed with data that was collected from monitored
resources over the last 24 hours. The
performance of each monitored resource is charted against the best practice guidelines for IBM Storage Virtualize storage systems.
- Optional:
If you want to view the performance charts for a period other than the default 24-hour period,
change the date for all of the charts. Click Last 24 hours and use the
calendar to specify a date.
- Optional:
Drill down to view detailed information about a specific I/O group, port, or node. Click a
resource from the chart's list.
For example, select the name of an I/O group in the Read Response Time by I/O
Group chart to view the average number of milliseconds taken by the I/O group to
complete a read operation.
By default, metrics are shown on the charts for the following time periods:
- The last 24 hours
- The same 24-hour period for yesterday
- The same 24-hour period for the day seven days before today
If you selected a date from the calendar, the metrics are shown on the charts for the following
time periods:
- The selected date
- The day before the selected date
- The day seven days before the selected date
