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//port//counters/

Configuration

This section contains the default TOML to configure the plugin. You can generate it using telegraf --usage infiniband.

[[inputs.infiniband]]

There are no configuration options for this plugin.

Metrics

You can find more information about the counters that are gathered here: https://community.mellanox.com/s/article/understanding-mlx5-linux-counters-and-status-parameters

There is a simple mapping from counter -> counter value. All counter values are 64 bit integers. A seperate measurement is made for each port. Each measurement is tagged with the device and port that it relates to. These are strings.
