InfiniBand 输入插件

此插件收集系统中所有 InfiniBand 设备和端口的统计信息。这些计数器可以在 /sys/class/infiniband/<dev>/port/<port>/counters/ 中找到，RDMA 计数器可以在 /sys/class/infiniband/<dev>/ports/<port>/hw_counters/ 中找到。

引入于: Telegraf v1.14.0 标签: network 操作系统支持: linux

全局配置选项

插件支持其他全局和插件配置设置，用于修改指标、标签和字段，创建别名以及配置插件顺序等任务。更多详情请参阅 CONFIGURATION.md。

配置

# Gets counters from all InfiniBand cards and ports installed
# This plugin ONLY supports Linux
[[inputs.infiniband]]
  # no configuration

  ## Collect RDMA counters
  # gather_rdma = false

Metrics

实际指标取决于 InfiniBand 设备，该插件使用从计数器 -> 计数器值的简单映射。

Nvidia 提供了有关收集的计数器的信息。

选择 counters 时，插件会发出以下字段

• infiniband

  • 标签 (tags)
