process cpu threshold
Use the process cpu threshold command to configure the rising and falling
thresholds for the issuance of the CPU overload SNMP trap and notification
via a SYSLOG message. Use the no form of the command to return the
thresholds to their default values.
Syntax
process cpu threshold type total rising percentage interval seconds [ falling
percentage interval seconds ]
no process cpu threshold total type {rising | falling }
• rising percentage —The rising CPU percentage threshold over which a trap
will be issued and a message logged. This is a percentage of CPU utilized
over the period and ranges from 1 to 100.
•
falling percentage —The falling threshold value under which a trap will be
issued and message logged. This is a percentage of CPU utilized and
ranges from 1 to 100.
•
interval seconds —The number of seconds in the exponential weighted
moving average period (multiple of 5 seconds).
Default Configuration
• The default rising-threshold-val is 75%.
• The default falling-threshold-val is 50%
• The default severity level is NOTICE.

User Guidelines
CPU utilization is calculated using Exponential Moving Weighted Average
(EMWA) over the total time period. The EMWA is calculated using the
following formula:
EMWA(current_period) = EMA(prev_period) + (currentUtilization –
EMA(prev_period)) * weight
