R0106-HP MSR Router Series Fundamentals Command Reference(V7)

212
Parameters
job job-id: Specifies a process by its ID. If you do not specify this option, the command displays the
historical CPU usage statistics for the entire system, which is the sum of the historical CPU usage statistics
for all processes in the system. To view the IDs and names of the running processes, use the display
process command. For more information, see Network Management and Monitoring Configuration
Guide.
slot slot-number: Specifies a card by its slot number. If you do not specify this option, the command
displays the historical CPU usage statistics for the active MPU. (On an MSR4000.)
cpu cpu-number: Specifies a CPU by its number. If you do not specify this option, the command displays
the historical CPU usage statistics for the default CPU. (On an MSR4000.)
Usage guidelines
After CPU usage monitoring is enabled, the system regularly samples CPU usage and saves the samples
to the history record buffer. This command displays the most recent 60 samples in a coordinate system
as follows:
• The vertical axis represents the CPU usage. If a statistic is not a multiple of the usage step, it is
rounded up or down to the closest multiple of the usage step, whichever is closer. For example, if the
CPU usage step is 5%, the statistic 53% is rounded up to 55%, and the statistic 52% is rounded
down to 50%.
• The horizontal axis represents the time.
• Consecutive pound signs (#) indicate the CPU usage at a specific time. The value on the vertical
axis for the topmost pound sign at a specific time represents the CPU usage at that time.
