snmp ifInOctets ifOutOctets

[tnk2k]

Hello All,

I'm trying to set up an item to watch the network interface throughput.

Now after reading the wiki page about SNMP & EthernetIface i still have the following questions:

- the data sent by ifInOctets is the total amount of data passed in octets, so this can be also referred to as in bytes?
- how does the deltaspeed works? lets say i the first value is: 121 and 10 seconds later it's 131. So the data past is 10 bytes. So i had 10 bytes passed in 10 seconds so i have an average of 1 byte per second?

- why does 'ploeger' on the snmp page use an multiplier 8? if i want the number of bits per second shouldn't i divide it instead of multiplying?

calculate bandwidth of system using SNMP in DOTNET

Hi,

I want to calculate bandwidth using SNMP.When i use OID's defined in MIB files like
1).iso.org.dod.internet.mgmt.mib-.interfaces.ifTable.ifEntry.ifInOctets:-.1.3.6.1.2.1.2.2.1.10

Iam getting output as below

ifInOctets.1
0
ifInOctets.2
0
ifInOctets.3
0
ifInOctets.4
0
etc.
These all are interfaces available on xyz machine.but i want to know what ifInOctets.1,ifInOctets.2 etc represents,so that i can calcutate bandwidth as per interface.Please guide me and tell me how to calculate bandwidth using SNMP.



Thanks
