Add support for InfiniBand
Browse files Browse the repository at this point in the history 
The Prometheus node exporter collects metrics for the InfiniBand network
protocol including the amount of packets sent and received, the number
of times the link has been downed and how many times the link has
recovered from an error state.

Reading all those information from sysfs is better placed in the procfs
library. Also collect the state, physical state, and the rate.
