Hi,
Are we talking about a standad network interface which shows up in the
OS as enSOMETHING? Then it should be covered by the kernel metrics which
node_exporter collects as part of netclass/netdev/netstat collectors
which are enabled by default.
We have no troubles monitoring our interfaces with 10G ports (or higher).
If this is some specialized hardware which is driven by a userspace
network stack or something, then things might be different
Can you share some more details how the interfaces look like in the
operating system and which metrics you are missing?
Kind regards,
Christian
