HTTP Output Plugin
This plugin writes metrics to a HTTP endpoint using one of the supported data formats. For data formats supporting batching, metrics are sent in batches by default.
⭐ Telegraf v1.7.0 🏷️ applications 💻 all
Global configuration options
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.
Secret-store support
This plugin supports secrets from secret-stores for the username, password
headers, and cookie_auth_headers option.
See the secret-store documentation for more details on how
to use them.
Configuration
# A plugin that can transmit metrics over HTTP
[[outputs.http]]
## URL is the address to send metrics to
url = "http://127.0.0.1:8080/telegraf"
## Timeout for HTTP message
# timeout = "5s"
## HTTP method, one of: "POST" or "PUT" or "PATCH"
# method = "POST"
## HTTP Basic Auth credentials
# username = "username"
# password = "pa$$word"
## OAuth2 Client Credentials Grant
# client_id = "clientid"
# client_secret = "secret"
# token_url = "https://indentityprovider/oauth2/v1/token"
# audience = ""
# scopes = ["urn:opc:idm:__myscopes__"]
## Goole API Auth
# google_application_credentials = "/etc/telegraf/example_secret.json"
## HTTP Proxy support
# use_system_proxy = false
# http_proxy_url = ""
## Optional TLS Config
# tls_ca = "/etc/telegraf/ca.pem"
# tls_cert = "/etc/telegraf/cert.pem"
# tls_key = "/etc/telegraf/key.pem"
## Use TLS but skip chain & host verification
# insecure_skip_verify = false
## Optional Cookie authentication
# cookie_auth_url = "https://localhost/authMe"
# cookie_auth_method = "POST"
# cookie_auth_username = "username"
# cookie_auth_password = "pa$$word"
# cookie_auth_headers = '{"Content-Type": "application/json", "X-MY-HEADER":"hello"}'
# cookie_auth_body = '{"username": "user", "password": "pa$$word", "authenticate": "me"}'
## cookie_auth_renewal not set or set to "0" will auth once and never renew the cookie
# cookie_auth_renewal = "5m"
## Data format to output.
## Each data format has it's own unique set of configuration options, read
## more about them here:
## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md
# data_format = "influx"
## Use batch serialization format (default) instead of line based format.
## Batch format is more efficient and should be used unless line based
## format is really needed.
# use_batch_format = true
## HTTP Content-Encoding for write request body, can be set to "gzip" to
## compress body or "identity" to apply no encoding.
# content_encoding = "identity"
## MaxIdleConns controls the maximum number of idle (keep-alive)
## connections across all hosts. Zero means no limit.
# max_idle_conn = 0
## MaxIdleConnsPerHost, if non-zero, controls the maximum idle
## (keep-alive) connections to keep per-host. If zero,
## DefaultMaxIdleConnsPerHost is used(2).
# max_idle_conn_per_host = 2
## Idle (keep-alive) connection timeout.
## Maximum amount of time before idle connection is closed.
## Zero means no limit.
# idle_conn_timeout = 0
## Amazon Region
#region = "us-east-1"
## Amazon Credentials
## Amazon Credentials are not built unless the following aws_service
## setting is set to a non-empty string. It may need to match the name of
## the service output to as well
#aws_service = "execute-api"
## 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 = ""
## Optional list of statuscodes (<200 or >300) upon which requests should not be retried
# non_retryable_statuscodes = [409, 413]
## NOTE: Due to the way TOML is parsed, tables must be at the END of the
## plugin definition, otherwise additional config options are read as part of
## the table
## Additional HTTP headers
# [outputs.http.headers]
# ## Should be set manually to "application/json" for json data_format
# Content-Type = "text/plain; charset=utf-8"
Google API Auth
The google_application_credentials setting is used with Google Cloud APIs.
It specifies the json key file. To learn about creating Google service accounts,
consult Google's oauth2 service account documentation.
An example use case is a metrics proxy deployed to Cloud Run. In this example,
the service account must have the "run.routes.invoke" permission.
Optional Cookie Authentication Settings
The optional Cookie Authentication Settings will retrieve a cookie from the given authorization endpoint, and use it in subsequent API requests. This is useful for services that do not provide OAuth or Basic Auth authentication, e.g. the Tesla Powerwall API, which uses a Cookie Auth Body to retrieve an authorization cookie. The Cookie Auth Renewal interval will renew the authorization by retrieving a new cookie at the given interval.
