Common protocol options

The following options are available for all protocols:

enabled

The enabled setting is a boolean setting to enable or disable protocols without having to comment out configuration sections. If set to false, the protocol is disabled.

The default value is true.

ports

Exception: For ICMP the option enabled has to be used instead.

The ports where Packetbeat will look to capture traffic for specific protocols. Packetbeat installs a BPF filter based on the ports specified in this section. If a packet doesn’t match the filter, very little CPU is required to discard the packet. Packetbeat also uses the ports specified here to determine which parser to use for each packet.

send_request

If this option is enabled, the raw message of the request (request field) is sent to Elasticsearch. The default is false. This option is useful when you want to index the whole request. Note that for HTTP, the body is not included by default, only the HTTP headers.

send_response

If this option is enabled, the raw message of the response (response field) is sent to Elasticsearch. The default is false. This option is useful when you want to index the whole response. Note that for HTTP, the body is not included by default, only the HTTP headers.

transaction_timeout

The per protocol transaction timeout. Expired transactions will no longer be correlated to incoming responses, but sent to Elasticsearch immediately.

fields

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.

packetbeat.protocols:
- type: http
  ports: [80]
  fields:
    service_id: nginx

fields_under_root

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 Packetbeat, then the custom fields overwrite the other fields.

tags

A list of tags that will be sent with the transaction event. This setting is optional.

processors

A list of processors to apply to the data generated by the protocol.

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