NetFlow (xm_netflow)
This module provides a parser for NetFlow payloads collected over UDP using im_udp. It supports the following NetFlow protocol versions: v1, v5, v7, v9, and IPFIX.
| To examine the supported platforms, see the list of installer packages in the Available Modules chapter. |
| This module only supports parsing NetFlow data received as UDP datagrams and does not support TCP or SCTP. |
| xm_netflow uses the IP address of the exporter device to distinguish between different devices so that templates with the same name would not conflict. |
The module exports an input parser which can be referenced in the UDP input instance with the InputType directive:
- InputType netflow
-
This input reader function parses the payload and extracts NetFlow specific fields.
Configuration
The xm_netflow module accepts only the common module directives.
The IpfixElementDefinition directive is optional.
- IpfixElementDefinition
-
The optional IpfixElementDefinition directive specifies the names and element type of a private element definition. This directive may be specified more than once if multiple private element definitions need to be loaded. It is often convenient to group the private element definitions into one or more separate configuration files that are included within the module definition.
The format of an IpfixElementDefinition is:
IpfixElementDefinition '<PEN Name>,<PEN>,<Element Name>,<Element ID>,<Element Type>'
Where:
<Pen Name>is a text string representing the organization defining the private element.<PEN>is the 32 bit integer Identifier of the organization defining the private element.<Element Name>is a text string naming the private element.<Element ID>, is the 16 bit integer Identifier the private element.<Element Type>is one of: [octetArray, unsigned8, unsigned16, unsigned32, unsigned64, signed8, signed16, signed32, signed64, float32, float64, boolean, macAddress, string, dateTimeSeconds, dateTimeMilliseconds, dateTimeMicroseconds, dateTimeNanoseconds, ipv4Address, ipv6Address, basicList, subTemplateList, subTemplateMultiList].<PEN Name>and<Element Name>must comply with the naming rules of a normal nxlog field see Fields.
