Getting information of NIC buffer and IP processing usage

[Guest]

Hello,

On a Windows XP workstation, I'm looking for a way to measure
- the buffer used / available in the Network Interface Card (NIC)
- the % of processor used by IP processing

Does any know how to get them

Thanks a lot

Best regards

Didier

Hello,

On a Windows XP workstation, I'm looking for a way to measure
- the buffer used / available in the Network Interface Card (NIC)

You can get this info using OID_GEN_TRANSMIT_BUFFER_SPACE
and OID_GEN_RECEIVE_BUFFER_SPACE.
However even if the netcard driver provides this info, it may be not accurate, because... just so it works.
For example if the NIC is bus mastering, it's "buffer" is limited only by PC memory.

- the % of processor used by IP processing

AFAIK this isn't available directly. Try a kernel profiler such as Intel VTune.

Thanks Pavel A.

I suppose you are talking abour SNMP OID rights ?
Can you please give me the corresponding numbers 1.3.6.1. .... for
OID_GEN_TRANSMIT_BUFFER_SPACE
OID_GEN_RECEIVE_BUFFER_SPACE

Please what exactly do these OIDs represent ?
- The total space available for tranmit buffer and receive buffer
(if there ae 2 different buffers ; I don't know)
- The amount available in each buffer
- The amount used in eahc buffer

No, these are NDIS OIDs :-(
