the above-mentioned processing type requests.
System
Select an MP blade from MP Blades in the component selection tree and choose the MP Blade
Util/Processing Type metric in the Available Metrics Choose Metric Category list. For more
information, see “MP Blades navigation path” (page 242). A stacked area graph is displayed in a
separate Utilization Metrics chart window and displays the MP blade utilization split up for the
different processing types. Each area represents the percentage of average MP blade utilization
by an individual processing type. The X-axis represents the duration that you select and the Y-axis
represents the average MP blade utilization. The chart title includes the P9000 disk array DKC
number, the MP blade ID, and the metric name for which the graph is plotted. The legends on the
top right corner of the stacked area graph help you to identify the corresponding processing types.
“MP blade utilization - Processing types” (page 274) displays a stacked area graph for the processing
types served by the MPB-1MA blade.
