Description

edit

Using this input you can receive single or multiline events over http(s). Applications can send an HTTP POST request with a body to the endpoint started by this input and Logstash will convert it into an event for subsequent processing. Users can pass plain text, JSON, or any formatted data and use a corresponding codec with this input. For Content-Type application/json the json codec is used, but for all other data formats, plain codec is used.

This input can also be used to receive webhook requests to integrate with other services and applications. By taking advantage of the vast plugin ecosystem available in Logstash you can trigger actionable events right from your application.

Security

edit

This plugin supports standard HTTP basic authentication headers to identify the requester. You can pass in a username, password combination while sending data to this input

You can also setup SSL and send data securely over https, with an option of validating the client’s certificate. Currently, the certificate setup is through Java Keystore format

Setting	Input type	Required
`additional_codecs`	hash	No
`host`	string	No

Also see Common Options for a list of options supported by all input plugins.

`additional_codecs`

edit

Value type is hash

There is no default value for this setting.

The JKS keystore to validate the client’s certificates

`keystore_password`

edit

Value type is password
There is no default value for this setting.

Common Options

edit

The following configuration options are supported by all input plugins:

Setting	Input type	Required
`add_field`	hash	No
`codec`	codec	No
`enable_metric`	boolean	No
`id`	string	No
`tags`	array	No
`type`	string	No

Details

edit

`add_field`

edit

Value type is hash
Default value is {}

Add a field to an event

`codec`

edit

Value type is codec
Default value is "plain"

The codec used for input data. Input codecs are a convenient method for decoding your data before it enters the input, without needing a separate filter in your Logstash pipeline.

`enable_metric`

edit

Value type is boolean
Default value is true

Disable or enable metric logging for this specific plugin instance by default we record all the metrics we can, but you can disable metrics collection for a specific plugin.

`id`

edit

Value type is string
There is no default value for this setting.

Add a unique ID to the plugin configuration. If no ID is specified, Logstash will generate one. It is strongly recommended to set this ID in your configuration. This is particularly useful when you have two or more plugins of the same type, for example, if you have 2 grok filters. Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.

output {
 stdout {
   id => "my_plugin_id"
 }
}

`tags`

edit

Value type is array
There is no default value for this setting.

Add any number of arbitrary tags to your event.

This can help with processing later.

`type`

edit

Value type is string
There is no default value for this setting.

This is the base class for Logstash inputs. Add a type field to all events handled by this input.

Types are used mainly for filter activation.

The type is stored as part of the event itself, so you can also use the type to search for it in Kibana.

If you try to set a type on an event that already has one (for example when you send an event from a shipper to an indexer) then a new input will not override the existing type. A type set at the shipper stays with that event for its life even when sent to another Logstash server.
