device-name
(config cpu-usage)#
show
Period : 10 sec.
Fault LED : Enabled
Traps : Enabled
Log : Enabled
Limit value : 75%
4.
Set the limit for CPU usage monitoring alerts to 5%:
device-name
(config monitor cpu-usage)#
limit 5
5.
Set the delta to trigger alerts for changes of 1% in the error rate:
device-name
(config monitor cpu-usage)#
delta 1 greater
device-name
(config monitor cpu-usage)#
end
6.
Display CPU usage monitoring configuration:
device-name
#
show monitor cpu-usage
Period : 10 sec.
Fault LED : Enabled
Traps : Enabled
Log : Enabled
Limit value : 5%
Delta value : 1%
Notify on delta if criteria greater than limit
7.
To check CPU usage monitoring, the trap output can be routed to the console:
device-name
#
configure terminal
device-name
(config)#
log cli-console trap debugging
device-name
(config)#
log nvram-history trap errors
Traps are displayed on the CLI console. Note that the CPU usage is checked at 10-second intervals,
as specified with the
period
command:
tHiSwMonitr: 1993/01/01 00:54:43 alerts: CPU Usage BIST fail: 7(limit 5)
tHiSwMonitr: 1993/01/01 00:54:43 alerts: CPU usage delta: current 7
tHiSwMonitr: 1993/01/01 00:54:53 alerts: CPU Usage BIST OK: 5(max 7)
tHiSwMonitr: 1993/01/01 00:55:03 alerts: CPU Usage BIST fail: 6(limit 5)
tHiSwMonitr: 1993/01/01 00:55:03 alerts: CPU usage delta: current 6
tHiSwMonitr: 1993/01/01 00:55:23 alerts: CPU usage delta: current 7
tHiSwMonitr: 1993/01/01 00:55:33 alerts: CPU Usage BIST OK: 5(max 7)
RAM Usage Monitoring
In the following example, RAM usage monitoring is enabled and configured with
period
,
limit
and
delta
commands.
1.
Enable RAM usage monitoring:
device-name
(config)#
monitor ram-usage enable
2. Enter into the RAM usage Monitoring Configuration mode:
device-name
(config)#
monitor ram-usage
