# How 5 min average and 5 min peak values are calculated

May 26th, 2009

Hi,

I ve got a basic question. Via SNMP i heard you can get the traffic statistics for a particular interface by two means.

1. 5 minute average value

2. 5 minute peak value

Below is my understanding of how 5 min average is calculated (correct me if im wrong):

5 min average value is calulated by the total number of bytes divided by 300 seconds and converting into bits. Say the total amount of bytes in 5 min is 16000. Then (18000*8)/300=480bps.

How 5 min peak value is calculated? Say if traffic pattern is like within 5 mins the peak value is attained in 3rd min then how does SNMP reports the peak value was attained in 3 rd min with the value. i want to know the logic of how 5 min peak value is calculated.

thanks

arun

Exactly what objects are you polling? Most peak objects come in pairs: one object the indicates the peak value, and one that indicates the peak time.
