InfiniBand Input Plugin

This plugin gathers statistics for all InfiniBand devices and ports on the system. These are the counters that can be found in /sys/class/infiniband/<dev>/port/<port>/counters/

Supported Platforms: Linux

Configuration

[[inputs.infiniband]]
  # no configuration

Metrics

Actual metrics depend on the InfiniBand devices, the plugin uses a simple mapping from counter -> counter value.

Information about the counters collected is provided by Mellanox.
