This is likely because the cards aren't visible to the OS in the correct way to end up in IF-MIB unless they're configured for Ethernet traffic.

If you can get at traffic data on the device itself, perhaps a unix-agent app will let you draw some graphs of it.

Hi all,

I would like to know if any of you have been able to monitor Infiniband traffic on Linux hosts with Observium.

I have added some nodes with Mellanox cards (MT27500 [ConnectX-3]) to Observium but it seems to see them only when they are configured for Ethernet traffic.

I have no issue monitoring Infiniband switches (mostly Mellanox SX6012 ) but is there a way to display Infiniband traffic from a Linux box in Observium ?


Best regards,
Louis
