• A column graph that displays the average utilization of the selected MP blade by each associated
consumer. For more information on how to read the column graph, see “Viewing top 20 consumers
of an MP blade” on page 305.
Example:
The following image displays the MPB-1MB utilization data for 53036, which belongs to the P9500
Disk Array type.
The MPB-1MB utilization data includes the following:
• MPB-1MB is the MP blade ID that was selected in the MP Blades Util% group box.
MPB-1MB is also listed in the MP Blade Configuration group box.
• MPB-1MB belongs to the Cluster 1 and the DKC 0.
• 1 in MPB-1MB represents the cluster # and MA represents the blade location for MPB-1MB.
• MP 0, MP 1, MP 2, and MP 3 are the MPs on MPB-1MB.
• The average utilization of MPB-1MB is 2%.
• The average utilization is calculated as the utilization of all the individual processors in MPB-1MB,
which is as follows: (MP1+MP2+MP3+MP4)/4.
• A total number of 264 consumers are assigned to MPB-1MB and grouped in the following com-
ponent types:
• LDEVs: 263
• Cont. Access Jnl Groups: 1
The average utilization of 2% is due to the 264 consumers that are utilizing the CPU cycles through
the associated processing types.
If you want to know which of the individual MPs on MPB-1MB is taking the processing load, click
the MPs in the MP Blade Configuration group box to view their utilization graphs. For example,
if over the last one day, one MP is servicing most of the I/O requests for the previous 23 hours,
you can plot the utilization graphs for all the MPs to view which one of them is processing the
maximum I/O requests.
• The processing types displayed in the Processing Distribution: MPB-1MB table are those utilizing
MPB-1MB to process requests from the associated consumers.
• The Avg. Util % in the Processing Distribution: MPB-1MB table displays the average MPB-1MB
utilization by each processing type, which totals to the 2% displayed in the MP Blade Summary:
MPB-1MB table.
