输入和输出集成概述
NATS Consumer Input Plugin 实现了从 NATS 消息主题实时数据消费,无缝集成到 Telegraf 数据管道中,用于监控和指标收集。
AWS Timestream Telegraf 插件使用户能够将指标直接发送到 Amazon 的 Timestream 服务,该服务专为时序数据管理而设计。此插件为身份验证、数据组织和保留设置提供了多种配置选项。
集成详情
NATS
NATS Consumer Plugin 允许 Telegraf 从指定的 NATS 主题读取指标,并根据支持的输入数据格式创建指标。利用队列组允许多个 Telegraf 实例并行地从 NATS 集群读取,从而提高吞吐量和可靠性。此插件还支持各种身份验证方法,包括用户名/密码、NATS 凭据文件和 nkey 种子文件,确保与 NATS 服务器的安全通信。由于 JetStream 等功能有助于历史消息的消费,因此在数据持久性和消息可靠性至关重要的环境中,此插件尤其有用。此外,配置各种操作参数的能力使此插件适用于高吞吐量场景,同时保持性能完整性。
AWS Timestream
此插件旨在高效地将指标写入 Amazon 的 Timestream 服务,Timestream 服务是一个针对物联网和运营应用优化的时序数据库。借助此插件,Telegraf 可以发送从各种来源收集的数据,并支持身份验证、数据组织和保留管理方面的灵活配置。它利用凭据链进行身份验证,允许各种方法,如 Web 身份、承担的角色和共享配置文件。用户可以定义指标在 Timestream 中的组织方式——是使用单个表还是多个表,以及控制磁存储和内存存储的保留期等方面。一个关键特性是它能够处理多指标记录,从而实现高效的数据摄取,并有助于减少多次写入的开销。在错误处理方面,该插件包含用于解决数据写入期间与 AWS 错误相关的常见问题的机制,例如用于节流的重试逻辑以及根据需要创建表的能力。
配置
NATS
[[inputs.nats_consumer]]
## urls of NATS servers
servers = ["nats://localhost:4222"]
## subject(s) to consume
## If you use jetstream you need to set the subjects
## in jetstream_subjects
subjects = ["telegraf"]
## jetstream subjects
## jetstream is a streaming technology inside of nats.
## With jetstream the nats-server persists messages and
## a consumer can consume historical messages. This is
## useful when telegraf needs to restart it don't miss a
## message. You need to configure the nats-server.
## https://docs.nats.io/nats-concepts/jetstream.
jetstream_subjects = ["js_telegraf"]
## name a queue group
queue_group = "telegraf_consumers"
## Optional authentication with username and password credentials
# username = ""
# password = ""
## Optional authentication with NATS credentials file (NATS 2.0)
# credentials = "/etc/telegraf/nats.creds"
## Optional authentication with nkey seed file (NATS 2.0)
# nkey_seed = "/etc/telegraf/seed.txt"
## Use Transport Layer Security
# secure = false
## Optional TLS Config
# tls_ca = "/etc/telegraf/ca.pem"
# tls_cert = "/etc/telegraf/cert.pem"
# tls_key = "/etc/telegraf/key.pem"
## Use TLS but skip chain & host verification
# insecure_skip_verify = false
## Sets the limits for pending msgs and bytes for each subscription
## These shouldn't need to be adjusted except in very high throughput scenarios
# pending_message_limit = 65536
# pending_bytes_limit = 67108864
## Max undelivered messages
## This plugin uses tracking metrics, which ensure messages are read to
## outputs before acknowledging them to the original broker to ensure data
## is not lost. This option sets the maximum messages to read from the
## broker that have not been written by an output.
##
## This value needs to be picked with awareness of the agent's
## metric_batch_size value as well. Setting max undelivered messages too high
## can result in a constant stream of data batches to the output. While
## setting it too low may never flush the broker's messages.
# max_undelivered_messages = 1000
## Data format to consume.
## Each data format has its own unique set of configuration options, read
## more about them here:
## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
data_format = "influx"
AWS Timestream

## Amazon Region
region = "us-east-1"
## Amazon Credentials
## Credentials are loaded in the following order:
## 1) Web identity provider credentials via STS if role_arn and web_identity_token_file are specified
## 2) Assumed credentials via STS if role_arn is specified
## 3) explicit credentials from 'access_key' and 'secret_key'
## 4) shared profile from 'profile'
## 5) environment variables
## 6) shared credentials file
## 7) EC2 Instance Profile
#access_key = ""
#secret_key = ""
#token = ""
#role_arn = ""
#web_identity_token_file = ""
#role_session_name = ""
#profile = ""
#shared_credential_file = ""
## Endpoint to make request against, the correct endpoint is automatically
## determined and this option should only be set if you wish to override the
## default.
## ex: endpoint_url = "http://localhost:8000"
# endpoint_url = ""
## Timestream database where the metrics will be inserted.
## The database must exist prior to starting Telegraf.
database_name = "yourDatabaseNameHere"
## Specifies if the plugin should describe the Timestream database upon starting
## to validate if it has access necessary permissions, connection, etc., as a safety check.
## If the describe operation fails, the plugin will not start
## and therefore the Telegraf agent will not start.
describe_database_on_start = false
## Specifies how the data is organized in Timestream.
## Valid values are: single-table, multi-table.
## When mapping_mode is set to single-table, all of the data is stored in a single table.
## When mapping_mode is set to multi-table, the data is organized and stored in multiple tables.
## The default is multi-table.
mapping_mode = "multi-table"
## Specifies if the plugin should create the table, if the table does not exist.
create_table_if_not_exists = true
## Specifies the Timestream table magnetic store retention period in days.
## Check Timestream documentation for more details.
## NOTE: This property is valid when create_table_if_not_exists = true.
create_table_magnetic_store_retention_period_in_days = 365
## Specifies the Timestream table memory store retention period in hours.

## NOTE: This property is valid when create_table_if_not_exists = true.
create_table_memory_store_retention_period_in_hours = 24
## Specifies how the data is written into Timestream.
## Valid values are: true, false
## When use_multi_measure_records is set to true, all of the tags and fields are stored
## as a single row in a Timestream table.
## When use_multi_measure_record is set to false, Timestream stores each field in a
## separate table row, thereby storing the tags multiple times (once for each field).
## The recommended setting is true.
## The default is false.
use_multi_measure_records = "false"
## Specifies the measure_name to use when sending multi-measure records.
## NOTE: This property is valid when use_multi_measure_records=true and mapping_mode=multi-table

## Specifies the name of the table to write data into
## NOTE: This property is valid when mapping_mode=single-table.
# single_table_name = ""
## Specifies the name of dimension when all of the data is being stored in a single table
## and the measurement name is transformed into the dimension value
## (see Mapping data from Influx to Timestream for details)
## NOTE: This property is valid when mapping_mode=single-table.
# single_table_dimension_name_for_telegraf_measurement_name = "namespace"
## Only valid and optional if create_table_if_not_exists = true
## Specifies the Timestream table tags.
