netflow input to read NetFlow and IPFIX exported flows
and options records over UDP.
This input supports NetFlow versions 1, 5, 6, 7, 8 and 9, as well as IPFIX. For NetFlow versions older than 9, fields are mapped automatically to NetFlow v9.
filebeat.inputs: - type: netflow max_message_size: 10KiB host: "0.0.0.0:2055" protocols: [ v5, v9, ipfix ] expiration_timeout: 30m queue_size: 8192
netflow input supports the following configuration options plus the
Common options described later.
The maximum size of the message received over UDP. The default is
The host and UDP port to listen on for event streams.
List of enabled protocols.
Valid values are
The time before an idle session or unused template is expired. Only applicable to v9 and IPFIX protocols. A value of zero disables expiration.
The maximum number of packets that can be queued for processing. Use this setting to avoid packet-loss when dealing with occasional bursts of traffic.
The following configuration options are supported by all inputs.
enabled option to enable and disable inputs. By default, enabled is
set to true.
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.
filebeat.inputs: - type: netflow . . . tags: ["json"]
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: netflow . . . fields: app_id: query_engine_12
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.
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.
The Ingest Node pipeline ID to set for the events generated by this input.
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.
