HTTP 输入插件
此插件从一个或多个提供支持的 数据格式 中数据的 HTTP 端点收集指标。
引入于: Telegraf v1.6.0 标签: applications, server 操作系统支持: all
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。
Secret-store 支持
此插件支持来自 secret-stores 的 username、password、token、headers 和 cookie_auth_headers 选项的 secret。有关如何使用它们的更多详细信息,请参阅 secret-store 文档。
配置
# Read formatted metrics from one or more HTTP endpoints
[[inputs.http]]
## One or more URLs from which to read formatted metrics.
urls = [
"https:///metrics",
"http+unix:///run/user/420/podman/podman.sock:/d/v4.0.0/libpod/pods/json"
]
## HTTP method
# method = "GET"
## Optional HTTP headers
# headers = {"X-Special-Header" = "Special-Value"}
## HTTP entity-body to send with POST/PUT requests.
# body = ""
## HTTP Content-Encoding for write request body, can be set to "gzip" to
## compress body or "identity" to apply no encoding.
# content_encoding = "identity"
## Optional Bearer token settings to use for the API calls.
## Use either the token itself or the token file if you need a token.
# token = "eyJhbGc...Qssw5c"
# token_file = "/path/to/file"
## Optional HTTP Basic Auth Credentials
# username = "username"
# password = "pa$$word"
## OAuth2 Client Credentials. The options 'client_id', 'client_secret', and 'token_url' are required to use OAuth2.
# client_id = "clientid"
# client_secret = "secret"
# token_url = "https://indentityprovider/oauth2/v1/token"
# scopes = ["urn:opc:idm:__myscopes__"]
## HTTP Proxy support
# use_system_proxy = false
# http_proxy_url = ""
## Optional TLS Config
## Set to true/false to enforce TLS being enabled/disabled. If not set,
## enable TLS only if any of the other options are specified.
# tls_enable =
## Trusted root certificates for server
# tls_ca = "/path/to/cafile"
## Used for TLS client certificate authentication
# tls_cert = "/path/to/certfile"
## Used for TLS client certificate authentication
# tls_key = "/path/to/keyfile"
## Password for the key file if it is encrypted
# tls_key_pwd = ""
## Send the specified TLS server name via SNI
# tls_server_name = "kubernetes.example.com"
## Minimal TLS version to accept by the client
# tls_min_version = "TLS12"
## List of ciphers to accept, by default all secure ciphers will be accepted
## See https://pkg.go.dev/crypto/tls#pkg-constants for supported values.
## Use "all", "secure" and "insecure" to add all support ciphers, secure
## suites or insecure suites respectively.
# tls_cipher_suites = ["secure"]
## Renegotiation method, "never", "once" or "freely"
# tls_renegotiation_method = "never"
## Use TLS but skip chain & host verification
# insecure_skip_verify = false
## Optional Cookie authentication
# cookie_auth_url = "https:///authMe"
# cookie_auth_method = "POST"
# cookie_auth_username = "username"
# cookie_auth_password = "pa$$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"
## Amount of time allowed to complete the HTTP request
# timeout = "5s"
## List of success status codes
# success_status_codes = [200]
## 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"可以通过“http+unix”或“https+unix”方案指定通过 Unix 域套接字的 HTTP 请求。请求 URL 应具有以下形式
http+unix:///path/to/service.sock:/api/endpoint注意:Unix 域套接字和请求端点的路径由冒号(“:”)分隔。

此输入插件收集的指标将取决于配置的 data_format 和 HTTP 端点返回的有效负载。
如果输入格式未指定值,则会添加下面的默认值
- http
- 标签 (tags)
- url
- 标签 (tags)
可选 Cookie 身份验证设置
可选的 Cookie 身份验证设置将从给定的授权端点检索 Cookie,并在后续的 API 请求中使用它。这对于不提供 OAuth 或 Basic Auth 身份验证的服务很有用,例如 Tesla Powerwall API,它使用 Cookie Auth Body 来检索授权 Cookie。Cookie Auth Renewal 间隔将以给定的间隔续订授权,通过检索新的 Cookie。
