Measuring NIC usage

[kammy_boy186]

Hi

We are using an HP DL380 file server, which has a 100 Mbs NIC.

Question - how can I measure the utilisation of this NIC to see if it's
worth upgrading to Gigabit ethernet? i.e, if the usage is generally at
50Mbs then there's no point, but if the NIC is always operating at
100Mbs, then it may be being used to capacity and an upgrade would
help.

Thx.
