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

Global configuration options

In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

Configuration

# Gets counters from all InfiniBand cards and ports installed
# This plugin ONLY supports Linux
[[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.
