Extended Monitoring of CPU Utilisation
(CR00012616)
This Software Version includes a new feature for monitoring CPU utilisation.
You can now set the switch to capture data about which specific functions the
CPU is executing, and what level of instantaneous usage the CPU is
experiencing. This allows you, in conjunction with your authorised distributor
or reseller, to diagnose the causes of high rates of CPU utilisation on the switch.
You can set the switch to capture data continuously, or only when the CPU
experiences a specific level of instantaneous usage. The switch holds up to 500
entries (10 seconds) of data about CPU utilisation.
To capture data when the CPU is experiencing a specific amount of
instantaneous usage, set the start and start percentages with the command:
activate cpu extended start=1..100 [stop=1..100]
When a start percentage is set, the switch automatically disables extended
monitoring once it has 500 data entries.
To enable extended monitoring, use the command:
enable cpu extended
This command also lets you capture data immediately, without first setting
start and stop percentages. This adds data entries continuously, until you stop
it. Only the last 10 seconds of data entries are stored.
To stop capturing data, and reset the
start
and
stop
parameters if they are set,
use the command:
disable cpu extended
To remove data entries and reset the
start
and
stop
parameters in the
activate
cpu extended
command, use the command:
reset cpu utilisation
This command interrupts active data capturing for a specific event. However,
monitoring remains enabled, and continues to collect data. This means you can
capture data for a particular event without having to disable and re-enable this
feature.
To see the extended CPU utilisation information (
Figure 1
,
Table 1
), use the
new optional
extended
parameter in the command:
show cpu extended
