Splunk Stream

Installation and Configuration Manual

Supported protocols

Splunk Stream Forwarder utilizes deep packet inspection to interpret protocol attributes from packet data collected on the wire.

For each supported protocol there are many different attributes. A common attribute is protocol_stack, which is a list of network layers that apply to the protocol that is being decoded.

Splunk Stream Forwarder starts to interpret protocols at the third layer, which is the network layer. Splunk Stream Forwarder can then interpret protocol layers up to layer seven, which is the application layer.

There are some instances where Stream is unable to interpret all of the network layers for the protocol. In this case, the protocol_stack field will only include the layers that can be decoded. An empty protocol_stack field indicates and unsupported protocol or a protocal with malformed data.

An example of a protocol_stack for Splunk network traffic would be:


An example of a mysql protocol_stack would be:


Supported protocols for field extraction

Protocol field extraction parses protocol data for specific event types, such as bytes_in, bytes_out, status, src_ip, and time_taken. You can add any protocols supported for field extraction to any stream configuration in the Configure Streams UI.

Stream supports the following protocols for field extraction:

Protocol Description
AMQP Advanced Messaging Queuing Protocol
DHCP Dynamic Host Configuration Protocol
DNS Domain Name Service
FTP File Transfer Protocol
HTTP Hypertext Transfer Protocol
ICMP Internet Control Message Protocol
IP Internet Protocol
IRC Internet Relay Chat

TDS Tabular Data Stream - Sybase/MSSQL Tabular Data Stream - Sybase/MSSQL
TNS Transparent Network Substrate (Oracle)
UDP User Datagram Protocol
XMPP Extensible Messaging and Presence Protocol

Protocol supported for detection only

Protocol detection refers to protocol classification at the transport layer only. For example, there are no Tor event types, only an app=tor field in the TCP event, which indicates Tor protocol at the application layer.

Protocols available only for detection cannot be selected in the Configure Streams UI and cannot be added to a stream configuration. To detect these protocols, you must run a search using the appropriate sourcetype and protocol classification.

How to detect protocols

To detect protocols, run a search that specifies the protocol classification in the tcp stream. For example:

sourcetype=stream:tcp app=tor

To detect all protocol classifications in the tcp and udp streams:

(sourcetype=stream:tcp OR sourcetype=stream:udp) | stats count by app

Stream supports the following protocols for detection only:
