Switch Management Commands 2270
EMWA(current_period) = EMA(prev_period) + (currentUtilization –
EMA(prev_period)) * weight
where weight = 2 / ((TotalTimePeriod/samplePeriod) + 1). The sample
period is 5 seconds. The utilization monitoring time period can be configured
from 5 secs to 86400 seconds in multiples of 5 seconds.
Setting a threshold or interval to 0 disables that individual function.
The falling-threshold percentage should be configured to be less than or
equal to the rising-threshold percentage. The switch reports the task level
CPU utilization for the last 5 second, 1 minute and 5 minute periods. To aid
the operator in troubleshooting when the CPU utilization has crossed the
rising threshold, the show proc cpu command has been extended to show the
task/total CPU utilization for the rising threshold period also. If the
utilization thresholds are not configured, then the utilization for last 5 secs, 1
minute and 5 minutes is displayed as before. The CPU utilization for any
given period is displayed in only after the first average has been calculated
over the time period.
For instance, the 5 minute average is shown only after the switch has been up
for more than 5 minutes. Additionally, whenever a time-period is configured
for CPU utilization monitoring, the existing utilization data for the time-
period is cleared and average is built again over the time period. This is done
to prevent generation of notifications based on the old utilization data.
