Hello,
I want to monitor bandwidth on a switch using SNMP and ifHCInOctets
and ifHCOutOctets.

My question is ifHCIn/OutOctets gives the total value in bytes
receieved on the interface so it will grow and grow.

I want to get mbits per second for this. Do i just take 2 readings at
1 min interval, obtain the difference. Divide it by 60 to get bytes
per second, then divide by 8 to get bits per second?

Thanks

Hans Jørgen Jakobsen...

Better to multiply by 8 Smile

yes thats the basic way to do it.
