a report using that template. These templates are termed as user-defined report templates. You can
also generate a report using the predefined report templates that come bundled with the P6000
Performance Advisor.
•
User-defined Reports. You can generate the report in PDF and CSV formats. The reports contain
historical data for the selected performance objects. In CSV format, raw historical performance
data is captured in the report. In PDF format, historical performance data is plotted as charts.
Performance data in either format is based on the granularity selected (number of data points
considered).
Optionally, you can have statistical data if PDF is chosen as the file format. The statistical
data in a report contains minimum, maximum, average, standard deviation, 90th, 95th, and
99th percentile values. The statistical data is based on performance data collected at the
specified polling interval.
•
Predefined Reports. You can create predefined reports from a fixed report template that is
bundled in the P6000 Performance Advisor application. These templates cannot be edited.
Predefined report templates for commonly used reports enable you to create these reports with
less effort and can be used for analyzing EVA Performance Metrics.
The granularity can be one of the following:
Daily Average
Displays an aggregate of all data points collected during a day.
Hourly Average Displays an aggregate of all data points collected during an hour.
Polling Interval Displays the collected data points based on the frequency of collection,
which is specified while configuring monitoring settings for the storage
system. All data points plotted after the specified interval are displayed
if polling interval is selected as the granularity type. For example, if you
select a frequency of 30 seconds, data points collected after every 30
seconds are plotted and displayed in the report.
Data points are based on the aggregate of performance data collected across controllers. To
understand how the aggregated values are calculated, refer the first two list items in the important
note provided for Key Metrics (see
“Key Metrics” (page 20) ). For polling interval granularity, the
duration cannot be more than 24 hours for creating a report.
For more information, see “Viewing and managing reports” (page 121) .
Load Distribution
Load distribution enables you to identify if the load across the host ports and controllers is well
balanced.
Load distribution can be classified as follows:
•
Load distribution across controllers
•
Load distribution across host ports
Load distribution across controllers
Load distribution across controllers provide information about the resource usage of both controllers.
It enables you to identify whether the load across both the controllers is well distributed. The load
data comprises of the following type of metrics:
•
“Live Data Metrics” (page 25)
•
“Historical Data Metrics” (page 25)
