HTTP Listener v2 Input Plugin
HTTP Listener v2 is a service input plugin that listens for metrics sent via HTTP. Metrics may be sent in any supported data format.
Note: The plugin previously known as http_listener
has been renamed
influxdb_listener
. If you would like Telegraf to act as a proxy/relay for
InfluxDB it is recommended to use influxdb_listener
.
Configuration:
This is a sample configuration for the plugin.
[[inputs.http_listener_v2]]
## Address and port to host HTTP listener on
service_address = ":8080"
## Path to listen to.
# path = "/telegraf"
## HTTP methods to accept.
# methods = ["POST", "PUT"]
## maximum duration before timing out read of the request
# read_timeout = "10s"
## maximum duration before timing out write of the response
# write_timeout = "10s"
## Maximum allowed http request body size in bytes.
## 0 means to use the default of 524,288,000 bytes (500 mebibytes)
# max_body_size = "500MB"
## Set one or more allowed client CA certificate file names to
## enable mutually authenticated TLS connections
# tls_allowed_cacerts = ["/etc/telegraf/clientca.pem"]
## Add service certificate and key
# tls_cert = "/etc/telegraf/cert.pem"
# tls_key = "/etc/telegraf/key.pem"
## Optional username and password to accept for HTTP basic authentication.
## You probably want to make sure you have TLS configured above for this.
# basic_username = "foobar"
# basic_password = "barfoo"
## 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"
Metrics:
Metrics are created from the request body and are dependant on the value of data_format
.
