Example (see Figure 26)MP blade utilization by processing types
3.12%
Average MP blade utilization by a processing type (average
from the previous to the current time stamp)
Total: 19.02%
Average MP blade utilization by all the processing types
associated with the MP blade for the overall duration
(16.4%)
Calculated as (3.12 / 19.02) * 100
The value 16.4% in 19.02% indicates the average utilization contributed
by the System processing type.
The 16.4% average utilization by the System processing type is further
contributed by the associated top 20 consumers. It indicates that 16.4%
of the CPU cycles are utilized to process the consumers requests. For
more information, see “Viewing top 20 consumers of an MP
blade” on page 305.
Average MP blade utilization by a processing type for the
overall duration
The above data helps you to understand the extent of an MP blade utilization by a particular processing
type when compared to the average utilization by all the processing types for the overall duration.
Viewing Aggregate Data for Metrics
You can view the average utilization for the components in a metrics category using the Stacked
button in the Charts screen. Select the required in the component selection tree, and then choose the
appropriate metric for which you want to view the average utilization data in the Choose Metrics
box.
NOTE:
You can select a maximum of eight components. The system does not display the stacked chart if more
that eight components are selected.
The Line chart for the selected components is displayed in the Chart window. To view the stacked
chart, click the stacked button. The button label changes to Line Chart. When you click the button
again the Line chart is displayed and the button label changes to Stacked.
Each area represents the percentage of average metrics utilization. The X-axis represents the date
and the time duration selected. The Y-axis represents the metrics utilization. The legends on the top
right corner of the stacked area graph help you to identify the components.
NOTE:
• You can stack the area chart for a maximum of 12 hours duration.
• For MP Blades utilization, the Stacked button is disabled for the following utilization metrics:
• MP Blade Util/Processing Type
• MP Blade Util – Top 20 Consumers
Figure 27 displays the stacked area graph for the average metrics utilization.
