HP P6000 Performance Advisor Software - Manual (Page 90)

For license expiry, install the required license for the storage system in HP P6000 Command View
and click Update Object Status in HP P6000 Performance Advisor for that storage system. This
action updates the license status in HP P6000 Performance Advisor. To install and manage licenses
for a storage system, see the HP P6000 Command View User Guide. To update object status, see
“Updating the object state for a storage system” (page 78) .
Viewing performance metrics of storage systems
This section describes various performance metrics, such as the following for a monitored storage
system and performance object:
•
“Viewing the Dashboard Overview” (page 90)
•
“Viewing a threshold summary” (page 101)
•
“Viewing a summary of key metrics” (page 108)
•
“Managing charts” (page 119)
•
“Viewing and managing reports” (page 121)
You can create charts and generate reports, and view the threshold and key metrics summary of
all performance objects in an object type.
IMPORTANT:
•
The performance data displayed is always with respect to the current monitored storage
systems and corresponding performance objects. HP P6000 Performance Advisor does not
display data for unmonitored objects.
•
Statistics data is only based on actual data collected at the daily polling interval.
•
Sequence of data displayed in charts and reports, and statistics displayed in reports, key
metrics, and KPI may differ if the selected time is within the Daylight Savings Time period.
•
If data from a storage system is being collected at 30-second intervals, a total of 400 data
points will be collected in a 3-hour and 20-minute period. So, if you plot a chart for 3 hours
and 20 minutes or less, all data samples collected are plotted, but if you want to view data
for any duration more than 3 hours and 20 minutes, one data sample is displayed for every
hour, which are average of all the data samples collected for every hour. In such cases, if
statistical table is also displayed, it might not match with the chart data samples. To understand
how the aggregated values are calculated, refer to the first two list items in the important note
provided for Key Metrics (see
“Key Metrics” (page 20) ).
WARNING! Data displayed on the P6000 Performance Advisor windows reflects the time zone
in which the server is located. HP strongly recommends that you do not modify the date and time
on your server, as it can result in irreversible data loss.
Viewing the Dashboard Overview
The dashboard for a storage system shows the overall performance of the storage system through:
•
Charts that can display live or historical data samples of the storage system
•
Statistical table that provides data based on historical performance of the storage system
Dashboard also constitutes the Key Performance Indicators that you configure to monitor the health
of your storage system. A Key Performance Indicator includes the performance object that you
monitor for a specific counter, which acts as key indicator to help you analyze the performance
of your storage system. Dashboard always pertains to a storage system. It is not available specifically
at the object type or performance object levels. You can choose to view the dashboard on
performance data collected over a duration (1 hour (minimum) and 24 hours (maximum)). By
default, the performance data collected over 1 hour is displayed.
