Data Plane Development Kit (DPDK) 输入插件
此插件收集由使用 数据平面开发工具包 (Data Plane Development Kit) 构建的应用程序公开的指标，这是一个用于加速数据包处理工作负载的广泛开源库。
由于 DPDK 很可能以 root 权限运行，DPDK 公开的遥测套接字也将需要 root 访问权限。请相应地调整权限！
有关 DPDK 在应用程序中使用详情和示例，请参阅 遥测用户指南。
此插件使用 v2 接口读取应用程序的遥测数据，并需要 DPDK 版本 v20.05 或更高版本。某些指标可能需要更高版本。推荐版本，特别是结合 in_memory 选项时，是 DPDK 21.11.2 或更高版本。
引入于: Telegraf v1.19.0 标签: applications, 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
# Reads metrics from DPDK applications using v2 telemetry interface.
# This plugin ONLY supports Linux
[[inputs.dpdk]]
## Path to DPDK telemetry socket. This shall point to v2 version of DPDK
## telemetry interface.
# socket_path = "/var/run/dpdk/rte/dpdk_telemetry.v2"
## Duration that defines how long the connected socket client will wait for
## a response before terminating connection.
## This includes both writing to and reading from socket. Since it's local
## socket access to a fast packet processing application, the timeout should
## be sufficient for most users.
## Setting the value to 0 disables the timeout (not recommended)
# socket_access_timeout = "200ms"
## Enables telemetry data collection for selected device types.
## Adding "ethdev" enables collection of telemetry from DPDK NICs (stats, xstats, link_status, info).
## Adding "rawdev" enables collection of telemetry from DPDK Raw Devices (xstats).
# device_types = ["ethdev"]
## List of custom, application-specific telemetry commands to query
## The list of available commands depend on the application deployed.
## Applications can register their own commands via telemetry library API
## https://doc.dpdk.org/guides/prog_guide/telemetry_lib.html#registering-commands
## For L3 Forwarding with Power Management Sample Application this could be:
## additional_commands = ["/l3fwd-power/stats"]
# additional_commands = []
## List of plugin options.
## Supported options:
## - "in_memory" option enables reading for multiple sockets when a dpdk application is running with --in-memory option.
## When option is enabled plugin will try to find additional socket paths related to provided socket_path.
## Details: https://doc.dpdk.org/guides/howto/telemetry.html#connecting-to-different-dpdk-processes
# plugin_options = ["in_memory"]
## Specifies plugin behavior regarding unreachable socket (which might not have been initialized yet).
## Available choices:
## - error: Telegraf will return an error during the startup and gather phases if socket is unreachable
## - ignore: Telegraf will ignore error regarding unreachable socket on both startup and gather
# unreachable_socket_behavior = "error"
## List of metadata fields which will be added to every metric produced by the plugin.
## Supported options:
## - "pid" - exposes PID of DPDK process. Example: pid=2179660i
## - "version" - exposes version of DPDK. Example: version="DPDK 21.11.2"
# metadata_fields = ["pid", "version"]
## Allows turning off collecting data for individual "ethdev" commands.
## Remove "/ethdev/link_status" from list to gather link status metrics.
[inputs.dpdk.ethdev]
exclude_commands = ["/ethdev/link_status"]
## When running multiple instances of the plugin it's recommended to add a
## unique tag to each instance to identify metrics exposed by an instance
## of DPDK application. This is useful when multiple DPDK apps run on a
## single host.
## [inputs.dpdk.tags]
## dpdk_instance = "my-fwd-app"此插件提供多种配置选项，请参阅下面的示例以获取更多使用信息。
示例：NIC 指标的最小配置
此配置允许获取通过 /ethdev/list 命令报告的所有设备的指标
/ethdev/info- 设备信息：名称、MAC 地址、缓冲区大小等 (自DPDK 21.11起)/ethdev/stats- 基本设备统计信息 (自DPDK 20.11起)/ethdev/xstats- 扩展设备统计信息/ethdev/link_status- 上/下链路状态
[[inputs.dpdk]]
device_types = ["ethdev"]由于此配置将查询 /ethdev/link_status，因此建议将超时时间增加到 socket_access_timeout = "10s"。
插件收集间隔应相应调整 (例如 interval = "30s")。
示例：排除 NIC 链路状态的收集
根据底层实现检查链路状态可能需要更长的时间。此配置可用于排除此遥测命令，以便更快地响应指标。
[[inputs.dpdk]]
device_types = ["ethdev"]
[inputs.dpdk.ethdev]
exclude_commands = ["/ethdev/link_status"]可以使用具有更高超时设置的单独插件实例独立获取 /ethdev/link_status。请参阅独立 NIC 链路状态配置和从同一主机上运行的多个 DPDK 实例获取指标示例以获取更多详细信息。
示例：独立 NIC 链路状态配置
此配置允许使用具有更高超时时间的单独配置来获取 /ethdev/link_status。
[[inputs.dpdk]]
interval = "30s"
socket_access_timeout = "10s"
device_types = ["ethdev"]
[inputs.dpdk.ethdev]
exclude_commands = ["/ethdev/info", "/ethdev/stats", "/ethdev/xstats"]示例：获取特定于应用程序的指标
此配置允许读取应用程序公开的自定义指标。示例遥测命令来自 L3 Forwarding with Power Management Sample Application。
[[inputs.dpdk]]
device_types = ["ethdev"]
additional_commands = ["/l3fwd-power/stats"]
[inputs.dpdk.ethdev]
exclude_commands = ["/ethdev/link_status"]additional_commands 中指定的命令条目应符合 DPDK 命令格式
- 命令条目格式：对于需要参数的命令，可以是
command或command,params，其中逗号 (,) 分隔命令和参数。 - 命令条目长度（带参数的命令）应为
< 1024字符。 - 命令长度（不带参数）应为
< 56字符。 - 命令必须以
/开头。
提供无效命令将阻止插件启动。附加命令允许重复，但在执行期间会被删除，因此每个命令在每个指标收集间隔期间只会执行一次。
示例：从同一主机上的多个 DPDK 实例获取指标
此配置允许从通过独立套接字公开其遥测接口的两个独立应用程序获取指标。对于每个插件实例，唯一的标签 [inputs.dpdk.tags] 允许区分它们。
# Instance #1 - L3 Forwarding with Power Management Application
[[inputs.dpdk]]
socket_path = "/var/run/dpdk/rte/l3fwd-power_telemetry.v2"
device_types = ["ethdev"]
additional_commands = ["/l3fwd-power/stats"]
[inputs.dpdk.ethdev]
exclude_commands = ["/ethdev/link_status"]
[inputs.dpdk.tags]
dpdk_instance = "l3fwd-power"
# Instance #2 - L2 Forwarding with Intel Cache Allocation Technology (CAT)
# Application
[[inputs.dpdk]]
socket_path = "/var/run/dpdk/rte/l2fwd-cat_telemetry.v2"
device_types = ["ethdev"]
[inputs.dpdk.ethdev]
exclude_commands = ["/ethdev/link_status"]
[inputs.dpdk.tags]
dpdk_instance = "l2fwd-cat"这利用了 Telegraf 添加自定义标签到输入插件度量的标准功能。
Metrics
DPDK 套接字接受 command,params 请求，并以 JSON 格式返回指标数据。来自 DPDK 套接字的所有指标都使用 Telegraf 的 JSON Flattener 进行展平，并作为字段公开。如果 DPDK 响应不包含任何信息（为空或为 null），则该响应将被丢弃。
注意： 由于 DPDK 允许在其遥测框架中注册自定义指标，因此 DPDK 的 JSON 响应可能包含各种指标集。虽然来自
/ethdev/stats的指标应该最稳定，但/ethdev/xstats可能包含特定于驱动程序的指标（取决于 DPDK 应用程序配置）。像/l3fwd-power/stats这样的特定于应用程序的命令可以返回其自身的特定指标集。
示例输出
输出包括插件名称 (dpdk) 以及一组标识查询层次结构的标签
dpdk,host=dpdk-host,dpdk_instance=l3fwd-power,command=/ethdev/stats,params=0 [fields] [timestamp]| 标签 | 描述 |
|---|---|
host | 机器的主机名（有关更多详细信息，请参阅 Telegraf Agent 配置） |
dpdk_instance | 来自 [inputs.dpdk.tags] 的自定义标签（可选） |
command | 执行的命令（不带参数） |
params | 命令参数，例如，对于 /ethdev/stats，它是 /ethdev/list 公开的 NIC 的 ID。对于使用 2 个 NIC 的 DPDK 应用程序，指标将输出例如 params=0，params=1。 |
