Zabbix show incorrect bandwidth

[haejung]

I am using 200Mbps internet link
but Zabbix's max value is over 200Mbps(real bandwith)I compared it with PRTG program, PRTG show me correct bandwith
PRTG didn't exceed real bandwith(200Mbps)

I think Zabbix graph is generally as same as PRTG value
but peak value(max value) is really strange

I think Multiplier value is not issue
because average graph is correct

I saw the issue about 32bit counter in forum
so I changed
from IF-MIB::ifInOctets.{#SNMPINDEX}
IF-MIB::ifHCInOctets.{#SNMPINDEX}

but it show me same result .

I was really frustrated with it
I spent more than one month to troubleshot it

I am monitoring cisco 7604 router(internet router)

Solution!!

Must add in the tab 'Preprocessing' the step 'Change per second' after the step 'Custom multiplier 8'.


See the attach.
