Configuration Note 5. CPU and Memory Utilization History
Version 7.2 23 Troubleshooting the MSBR
5 CPU and Memory Utilization History
The MSBR device has an option to view the CPU history. The MSBR device includes two
CPUs: Voice CPU and Data CPU. You can view both CPU utilization and memory utilization
history for both of these CPUs.
5.1 CPU Utilization History
The CPUs utilization history is collected for up to 72 hours according to the following:
For the last 60 seconds, the CPU utilization is saved on a per second basis i.e. the
MSBR retrieves the CPU utilization history of every second in the last minute.
For the last 60 minutes (last hour), the MSBR retrieves 60 values. Every retrieved
value is the average of the CPU utilization for every 60 second interval.
For the last 72 hours (3 days) the MSBR retrieves 72 values. Every retrieved value is
the average of the CPU utilization for every 60 minute interval.
The following commands show CPU utilization values:
Command Description
show system cpu-util history
data
Show data CPU utilization history
show system cpu-util history
voice
Show voice CPU utilization history
The output of the command is graphical, showing time on the X axis, and CPU utilization on
the Y axis. The numbers at the bottom of the Y axis represent the last time that a
measurement of a utilization value was taken. The value at the top of the graph is the
utilization value of the CPU.
Example:
Mediant 500 - MSBR# show system cpu-util history data
