The dpdk
plugin collects metrics exposed by applications built with Data
Plane Development Kit which is an extensive set of open
source libraries designed for accelerating packet processing workloads.
DPDK provides APIs that enable exposing various statistics from the devices used by DPDK applications and enable exposing KPI metrics directly from applications. Device statistics include e.g. common statistics available across NICs, like: received and sent packets, received and sent bytes etc. In addition to this generic statistics, an extended statistics API is available that allows providing more detailed, driver-specific metrics that are not available as generic statistics.
DPDK Release 20.05
introduced updated telemetry interface that enables DPDK libraries and
applications to provide their telemetry. This is referred to as v2
version of
this socket-based telemetry interface. This release enabled e.g. reading
driver-specific extended stats (/ethdev/xstats
) via this new interface.
DPDK Release 20.11
introduced reading via v2
interface common statistics (/ethdev/stats
) in
addition to existing (/ethdev/xstats
).
DPDK Release 21.11
introduced reading via v2
interface additional ethernet device information
(/ethdev/info
).
This version also adds support for exposing telemetry from multiple
--in-memory
instances of DPDK via dedicated sockets.
The plugin supports reading from those sockets when in_memory
option is set.
The example usage of v2
telemetry interface can be found in Telemetry User
Guide. A variety of DPDK
Sample Applications is
also available for users to discover and test the capabilities of DPDK libraries
and to explore the exposed metrics.
DPDK Version Info: This plugin uses this
v2
interface to read telemetry data from applications build withDPDK version >= 20.05
. The default configuration include reading common statistics from/ethdev/stats
that is available fromDPDK version >= 20.11
. When usingDPDK 20.05 <= version < DPDK 20.11
it is recommended to disable querying/ethdev/stats
by setting correspondingexclude_commands
configuration option.NOTE: Since DPDK will most likely run with root privileges, the socket telemetry interface exposed by DPDK will also require root access. This means that either access permissions have to be adjusted for socket telemetry interface to allow Telegraf to access it, or Telegraf should run with root privileges.
NOTE: There are known issues with exposing telemetry from multiple
--in-memory
instances while usingDPDK 21.11.1
. The recommended version to use in conjunction within_memory
plugin option isDPDK 21.11.2
or higher.
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.
# 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"
This plugin offers multiple configuration options, please review examples below for additional usage information.
This configuration allows getting metrics for all devices reported via
/ethdev/list
command:
/ethdev/info
- device information: name, MAC address, buffers size, etc. (sinceDPDK 21.11
)/ethdev/stats
- basic device statistics (sinceDPDK 20.11
)/ethdev/xstats
- extended device statistics/ethdev/link_status
- up/down link status
[[inputs.dpdk]]
device_types = ["ethdev"]
Since this configuration will query /ethdev/link_status
it's recommended to
increase timeout to socket_access_timeout = "10s"
.
The plugin collecting interval
should be adjusted accordingly (e.g. interval = "30s"
).
Checking link status depending on underlying implementation may take more time to complete. This configuration can be used to exclude this telemetry command to allow faster response for metrics.
[[inputs.dpdk]]
device_types = ["ethdev"]
[inputs.dpdk.ethdev]
exclude_commands = ["/ethdev/link_status"]
A separate plugin instance with higher timeout settings can be used to get
/ethdev/link_status
independently. Consult Independent NIC link status
configuration and Getting
metrics from multiple DPDK instances running on same
host
examples for further details.
This configuration allows getting /ethdev/link_status
using separate
configuration, with higher timeout.
[[inputs.dpdk]]
interval = "30s"
socket_access_timeout = "10s"
device_types = ["ethdev"]
[inputs.dpdk.ethdev]
exclude_commands = ["/ethdev/info", "/ethdev/stats", "/ethdev/xstats"]
This configuration allows reading custom metrics exposed by applications. Example telemetry command obtained from 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"]
Command entries specified in additional_commands
should match DPDK command
format:
- Command entry format: either
command
orcommand,params
for commands that expect parameters, where comma (,
) separates command from params. - Command entry length (command with params) should be
< 1024
characters. - Command length (without params) should be
< 56
characters. - Commands have to start with
/
.
Providing invalid commands will prevent the plugin from starting. Additional commands allow duplicates, but they will be removed during execution, so each command will be executed only once during each metric gathering interval.
This configuration allows getting metrics from two separate applications
exposing their telemetry interfaces via separate sockets. For each plugin
instance a unique tag [inputs.dpdk.tags]
allows distinguishing between them.
# 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"
This utilizes Telegraf's standard capability of adding custom tags to input plugin's measurements.
The DPDK socket accepts command,params
requests and returns metric data in
JSON format. All metrics from DPDK socket become flattened using Telegraf's
JSON Flattener and exposed as fields. If DPDK
response contains no information (is empty or is null) then such response will
be discarded.
NOTE: Since DPDK allows registering custom metrics in its telemetry framework the JSON response from DPDK may contain various sets of metrics. While metrics from
/ethdev/stats
should be most stable, the/ethdev/xstats
may contain driver-specific metrics (depending on DPDK application configuration). The application-specific commands like/l3fwd-power/stats
can return their own specific set of metrics.
The output consists of plugin name (dpdk
), and a set of tags that identify
querying hierarchy:
dpdk,host=dpdk-host,dpdk_instance=l3fwd-power,command=/ethdev/stats,params=0 [fields] [timestamp]
Tag | Description |
---|---|
host |
hostname of the machine (consult Telegraf Agent configuration for additional details) |
dpdk_instance |
custom tag from [inputs.dpdk.tags] (optional) |
command |
executed command (without params) |
params |
command parameter, e.g. for /ethdev/stats it is the ID of NIC as exposed by /ethdev/list . For DPDK app that uses 2 NICs the metrics will output e.g. params=0 , params=1 . |
