Monitoring a fiber card's throughput

[Shane Presley]

Hello,

We use MRTG to monitor our RedHat servers. It automatically detects
the ethernet cards, and produces graphs of our ethernet interface
throughput/bandwidth utilization.

We also have a fiber card installed in the server, for connectivity to
our SAN.  It's a Qlgoic 2460.

Does anybody know if MIBs exist (or some other method) to monitor the
throughput on the fiber card?

Thanks
Shane
