KPIs
The Key Performance Indicators (KPI) functionality helps you view historical data of performance
objects for counters that you consider important. The KPI data is available as charts and statistical
data, and always included in the dashboard summary displayed for a storage system. The statistical
table displays basic statistics (Minimum, Maximum, Average) and the recent performance value.
Also, advanced statistical data is available, which includes the Standard Deviation, 90th, 95th,
and 99th percentile in addition to the basic statistics. It is required that you identify KPIs for your
storage system if you regularly monitor the performance of corresponding sets of objects for specific
counters. You can configure a KPI record for each combination of performance object and counter
that you want to monitor. For example, if you have virtual disks, Data 1 and Data 2, configured
for a critical application and you want to monitor their throughput along both the controllers CPU%
in your storage system, you may like to configure them in Key Performance Indicator.
If a performance object configured as part of a KPI record is deleted in HP P6000 Command View,
the performance data collected until the time of deletion is still displayed. The recent value in the
statistical table still shows the most recent value available before the performance object was
deleted.
On the Dashboard Overview page, click the Advanced link to go to the Key Performance Indicator
tab and view additional statistical data like Standard Deviation, Percentiles values. For more
information, see
“Key Performance Indicators – Dashboard” (page 97) .
Key Metrics
Key Metrics helps you view performance data for storage systems and objects for the supported
counters (key counters) defined by HP P6000 Performance Advisor. To know the supported key
metric counters, see
“Supported counters” (page 167) .
HP P6000 Performance Advisor provides key metric data for every monitored storage system and
performance object in the form of:
•
Key metric charts
•
Key metric statistical table
You can also view key metrics summary of all monitored performance objects for an object type,
where the historical statistical data of those objects is displayed for the key counters. At this level,
you can sort performance objects based on their performance data to identify highest and least
utilized objects. For example, you can sort key metrics summary for the Virtual Disks object type
to view the top ten performing virtual disks. Additionally, you can filter records to view only the
required performance objects. You can drill down from the object type to view key metric data for
the specific performance objects in that object type. The key metric data acts as key indicator and
enables you to take a quick look at performance data of objects, based on which you can plot
charts and generate reports to view specific details of the object's performance.
