acknowledgements

optional object

Deprecated

This field is deprecated.

Controls how acknowledgements are handled by this source.

This setting is deprecated in favor of enabling acknowledgements at the global or sink level.

Enabling or disabling acknowledgements at the source level has no effect on acknowledgement behavior.

See End-to-end Acknowledgements for more information on how event acknowledgement is handled.

acknowledgements.enabled

optional bool
Whether or not end-to-end acknowledgements are enabled for this source.

connection_string

required string literal

URI for the AMQP server.

The URI has the format of amqp://<user>:<password>@<host>:<port>/<vhost>?timeout=<seconds>.

The default vhost can be specified by using a value of %2f.

To connect over TLS, a scheme of amqps can be specified instead. For example, amqps://.... Additional TLS settings, such as client certificate verification, can be configured under the tls section.

Examples 
"amqp://user:password@127.0.0.1:5672/%2f?timeout=10"

consumer

optional string literal
The identifier for the consumer.
Examples 
"consumer-group-name"
default: vector

decoding

optional object
Configures how events are decoded from raw bytes.

decoding.avro

required object
Apache Avro-specific encoder options.
Relevant when: codec = "avro"
decoding.avro.schema
required string literal

The Avro schema definition. Please note that the following [apache_avro::types::Value] variants are currently not supported:

  • Date
  • Decimal
  • Duration
  • Fixed
  • TimeMillis
Examples 
"{ \"type\": \"record\", \"name\": \"log\", \"fields\": [{ \"name\": \"message\", \"type\": \"string\" }] }"
decoding.avro.strip_schema_id_prefix
required bool
For Avro datum encoded in Kafka messages, the bytes are prefixed with the schema ID. Set this to true to strip the schema ID prefix. According to Confluent Kafka’s document.

decoding.codec

optional string literal enum
The codec to use for decoding events.
Enum options
OptionDescription
avroDecodes the raw bytes as as an Apache Avro message.
bytesUses the raw bytes as-is.
gelf

Decodes the raw bytes as a GELF message.

This codec is experimental for the following reason:

The GELF specification is more strict than the actual Graylog receiver. Vector’s decoder currently adheres more strictly to the GELF spec, with the exception that some characters such as @ are allowed in field names.

Other GELF codecs such as Loki’s, use a Go SDK that is maintained by Graylog, and is much more relaxed than the GELF spec.

Going forward, Vector will use that Go SDK as the reference implementation, which means the codec may continue to relax the enforcement of specification.

influxdbDecodes the raw bytes as an Influxdb Line Protocol message.
jsonDecodes the raw bytes as JSON.
native

Decodes the raw bytes as native Protocol Buffers format.

This codec is experimental.

native_json

Decodes the raw bytes as native JSON format.

This codec is experimental.

protobufDecodes the raw bytes as protobuf.
syslog

Decodes the raw bytes as a Syslog message.

Decodes either as the RFC 3164-style format (“old” style) or the RFC 5424-style format (“new” style, includes structured data).

vrlDecodes the raw bytes as a string and passes them as input to a VRL program.
default: bytes

decoding.gelf

default: true

decoding.vrl

required object
VRL-specific decoding options.
Relevant when: codec = "vrl"
decoding.vrl.source
required string literal
The Vector Remap Language (VRL) program to execute for each event. Note that the final contents of the . target will be used as the decoding result. Compilation error or use of ‘abort’ in a program will result in a decoding error.
decoding.vrl.timezone
optional string literal

The name of the timezone to apply to timestamp conversions that do not contain an explicit time zone. The time zone name may be any name in the TZ database, or local to indicate system local time.

If not set, local will be used.

Examples 
"local"
"America/New_York"
"EST5EDT"

exchange_key

optional string literal
The AMQP exchange key.
default: exchange

framing

optional object

Framing configuration.

Framing handles how events are separated when encoded in a raw byte form, where each event is a frame that must be prefixed, or delimited, in a way that marks where an event begins and ends within the byte stream.

framing.character_delimited

required object
Options for the character delimited decoder.
Relevant when: method = "character_delimited"
framing.character_delimited.delimiter
required ascii_char
The character that delimits byte sequences.
framing.character_delimited.max_length
optional uint

The maximum length of the byte buffer.

This length does not include the trailing delimiter.

By default, there is no maximum length enforced. If events are malformed, this can lead to additional resource usage as events continue to be buffered in memory, and can potentially lead to memory exhaustion in extreme cases.

If there is a risk of processing malformed data, such as logs with user-controlled input, consider setting the maximum length to a reasonably large value as a safety net. This ensures that processing is not actually unbounded.

framing.chunked_gelf

optional object
Options for the chunked GELF decoder.
Relevant when: method = "chunked_gelf"
framing.chunked_gelf.decompression
optional string literal enum
Decompression configuration for GELF messages.
Enum options
OptionDescription
AutoAutomatically detect the decompression method based on the magic bytes of the message.
GzipUse Gzip decompression.
NoneDo not decompress the message.
ZlibUse Zlib decompression.
default: Auto
framing.chunked_gelf.max_length
optional uint

The maximum length of a single GELF message, in bytes. Messages longer than this length will be dropped. If this option is not set, the decoder does not limit the length of messages and the per-message memory is unbounded.

Note that a message can be composed of multiple chunks and this limit is applied to the whole message, not to individual chunks.

This limit takes only into account the message’s payload and the GELF header bytes are excluded from the calculation. The message’s payload is the concatenation of all the chunks’ payloads.

framing.chunked_gelf.pending_messages_limit
optional uint
The maximum number of pending incomplete messages. If this limit is reached, the decoder starts dropping chunks of new messages, ensuring the memory usage of the decoder’s state is bounded. If this option is not set, the decoder does not limit the number of pending messages and the memory usage of its messages buffer can grow unbounded. This matches Graylog Server’s behavior.
framing.chunked_gelf.timeout_secs
optional float
The timeout, in seconds, for a message to be fully received. If the timeout is reached, the decoder drops all the received chunks of the timed out message.
default: 5

framing.length_delimited

required object
Options for the length delimited decoder.
Relevant when: method = "length_delimited"
framing.length_delimited.length_field_is_big_endian
optional bool
Length field byte order (little or big endian)
default: true
framing.length_delimited.length_field_length
optional uint
Number of bytes representing the field length
default: 4
framing.length_delimited.length_field_offset
optional uint
Number of bytes in the header before the length field
framing.length_delimited.max_frame_length
optional uint
Maximum frame length
default: 8.388608e+06

framing.method

optional string literal enum
The framing method.
Enum options
OptionDescription
bytesByte frames are passed through as-is according to the underlying I/O boundaries (for example, split between messages or stream segments).
character_delimitedByte frames which are delimited by a chosen character.
chunked_gelfByte frames which are chunked GELF messages.
length_delimitedByte frames which are prefixed by an unsigned big-endian 32-bit integer indicating the length.
newline_delimitedByte frames which are delimited by a newline character.
octet_countingByte frames according to the octet counting format.
default: bytes

framing.newline_delimited

optional object
Options for the newline delimited decoder.
Relevant when: method = "newline_delimited"
framing.newline_delimited.max_length
optional uint

The maximum length of the byte buffer.

This length does not include the trailing delimiter.

By default, there is no maximum length enforced. If events are malformed, this can lead to additional resource usage as events continue to be buffered in memory, and can potentially lead to memory exhaustion in extreme cases.

If there is a risk of processing malformed data, such as logs with user-controlled input, consider setting the maximum length to a reasonably large value as a safety net. This ensures that processing is not actually unbounded.

framing.octet_counting

optional object
Options for the octet counting decoder.
Relevant when: method = "octet_counting"
framing.octet_counting.max_length
optional uint
The maximum length of the byte buffer.

offset_key

optional string literal
The AMQP offset key.
default: offset

queue

optional string literal
The name of the queue to consume.
default: vector

routing_key_field

optional string literal
The AMQP routing key.
default: routing

tls

optional object
TLS configuration.

tls.alpn_protocols

optional [string]

Sets the list of supported ALPN protocols.

Declare the supported ALPN protocols, which are used during negotiation with peer. They are prioritized in the order that they are defined.

tls.ca_file

optional string literal

Absolute path to an additional CA certificate file.

The certificate must be in the DER or PEM (X.509) format. Additionally, the certificate can be provided as an inline string in PEM format.

Examples 
"/path/to/certificate_authority.crt"

tls.crt_file

optional string literal

Absolute path to a certificate file used to identify this server.

The certificate must be in DER, PEM (X.509), or PKCS#12 format. Additionally, the certificate can be provided as an inline string in PEM format.

If this is set, and is not a PKCS#12 archive, key_file must also be set.

Examples 
"/path/to/host_certificate.crt"

tls.key_file

optional string literal

Absolute path to a private key file used to identify this server.

The key must be in DER or PEM (PKCS#8) format. Additionally, the key can be provided as an inline string in PEM format.

Examples 
"/path/to/host_certificate.key"

tls.key_pass

optional string literal

Passphrase used to unlock the encrypted key file.

This has no effect unless key_file is set.

Examples 
"${KEY_PASS_ENV_VAR}"
"PassWord1"

tls.server_name

optional string literal

Server name to use when using Server Name Indication (SNI).

Only relevant for outgoing connections.

Examples 
"www.example.com"

tls.verify_certificate

optional bool

Enables certificate verification. For components that create a server, this requires that the client connections have a valid client certificate. For components that initiate requests, this validates that the upstream has a valid certificate.

If enabled, certificates must not be expired and must be issued by a trusted issuer. This verification operates in a hierarchical manner, checking that the leaf certificate (the certificate presented by the client/server) is not only valid, but that the issuer of that certificate is also valid, and so on until the verification process reaches a root certificate.

Do NOT set this to false unless you understand the risks of not verifying the validity of certificates.

tls.verify_hostname

optional bool

Enables hostname verification.

If enabled, the hostname used to connect to the remote host must be present in the TLS certificate presented by the remote host, either as the Common Name or as an entry in the Subject Alternative Name extension.

Only relevant for outgoing connections.

Do NOT set this to false unless you understand the risks of not verifying the remote hostname.

Outputs

<component_id>

Default output stream of the component. Use this component’s ID as an input to downstream transforms and sinks.

How it works

Context

By default, the amqp source augments events with helpful context keys.

Lapin

The amqp source and sink uses lapin under the hood. This is a reliable pure rust library that facilitates communication with AMQP servers such as RabbitMQ.

State

This component is stateless, meaning its behavior is consistent across each input.
