Function
Enables the SNMP health monitor on the
router. The health monitor periodically
(the time you specify in the interval field)
checks the following key indicators of
router health:
Percentage of file storage used
Percentage of Routing Engine CPU
used
Percentage of Routing Engine
memory used
Percentage of memory used for
each system process
Percentage of CPU used by the
forwarding process
Percentage of memory used for
temporary storage by the
forwarding process
Determines the sampling frequency, in
seconds, over which the key health
indicators are sampled and compared
with the rising and falling thresholds.
For example, if you configure the
interval as 100 seconds, the values are
checked every 100 seconds.
Value at which you want SNMP to
generate an event (trap and system log
message) when the value of a sampled
indicator is increasing.
For example, if the rising threshold is 90
(the default), SNMP generates an event
when the value of any key indicator
reaches or exceeds 90 percent.
Value at which you want SNMP to
generate an event (trap and system log
message) when the value of a sampled
indicator is decreasing.
For example, if the falling threshold is
80 (the default), SNMP generates an
event when the value of any key
indicator falls back to 80 percent or less.

Your Action
Select the check box to enable the health
monitor and configure options. If you
do not select the check box, the health
monitor is disabled.
NOTE: If you select only the Enable
Health Monitoring check box and do not
specify the options, then SNMP health
monitoring is enabled with the default
values for the options.
Enter an interval time, in seconds,
between 1 and 2147483647
The default value is

Enter a value between
The default value is
Enter a value between
The default value is
NOTE: The falling threshold value must
be less than the rising threshold value.
