TCP inputedit

Warning

This functionality is experimental and may be changed or removed completely in a future release. Elastic will take a best effort approach to fix any issues, but experimental features are not subject to the support SLA of official GA features.

Use the TCP input to read events over TCP.

Example configuration:

filebeat.inputs:
- type: tcp
  max_message_size: 10MiB
  host: "localhost:9000"

Configuration optionsedit

The tcp input supports the following configuration options plus the Common options described later.

max_message_sizeedit

The maximum size of the message received over TCP. The default is 20MiB.

hostedit

The host and TCP port to listen on for event streams.

line_delimiteredit

Specify the characters used to split the incoming events. The default is \n.

timeoutedit

The number of seconds of inactivity before a remote connection is closed. The default is 300s.

ssledit

Configuration options for SSL parameters like the certificate, key and the certificate authorities to use.

See Specify SSL settings for more information.

Common optionsedit

The following configuration options are supported by all inputs.

enablededit

Use the enabled option to enable and disable inputs. By default, enabled is set to true.

tagsedit

A list of tags that Filebeat includes in the tags field of each published event. Tags make it easy to select specific events in Kibana or apply conditional filtering in Logstash. These tags will be appended to the list of tags specified in the general configuration.

Example:

filebeat.inputs:
- type: tcp
  . . .
  tags: ["json"]
fieldsedit

Optional fields that you can specify to add additional information to the output. For example, you might add fields that you can use for filtering log data. Fields can be scalar values, arrays, dictionaries, or any nested combination of these. By default, the fields that you specify here will be grouped under a fields sub-dictionary in the output document. To store the custom fields as top-level fields, set the fields_under_root option to true. If a duplicate field is declared in the general configuration, then its value will be overwritten by the value declared here.

filebeat.inputs:
- type: tcp
  . . .
  fields:
    app_id: query_engine_12
fields_under_rootedit

If this option is set to true, the custom fields are stored as top-level fields in the output document instead of being grouped under a fields sub-dictionary. If the custom field names conflict with other field names added by Filebeat, then the custom fields overwrite the other fields.

processorsedit

A list of processors to apply to the input data.

See Filter and enhance the exported data for information about specifying processors in your config.

pipelineedit

The Ingest Node pipeline ID to set for the events generated by this input.

Note

The pipeline ID can also be configured in the Elasticsearch output, but this option usually results in simpler configuration files. If the pipeline is configured both in the input and output, the option from the input is used.
