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 uint

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.method

optional string literal enum

The framing method.

Enum options

Option	Description
`bytes`	Byte frames are passed through as-is according to the underlying I/O boundaries (for example, split between messages or stream segments).
`character_delimited`	Byte frames which are delimited by a chosen character.
`length_delimited`	Byte frames which are prefixed by an unsigned big-endian 32-bit integer indicating the length.
`newline_delimited`	Byte frames which are delimited by a newline character.
`octet_counting`	Byte frames according to the octet counting format.

default: newline_delimited

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.

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.

multiline

optional object

Multiline aggregation configuration.

If not specified, multiline aggregation is disabled.

multiline.condition_pattern

required string literal

Regular expression pattern that is used to determine whether or not more lines should be read.

This setting must be configured in conjunction with mode.

Examples

"^[\\s]+"

"\\\\$"

"^(INFO|ERROR) "

";$"

multiline.mode

required string literal enum

Aggregation mode.

This setting must be configured in conjunction with condition_pattern.

Enum options

Option	Description
`continue_past`	All consecutive lines matching this pattern, plus one additional line, are included in the group. This is useful in cases where a log message ends with a continuation marker, such as a backslash, indicating that the following line is part of the same message.
`continue_through`	All consecutive lines matching this pattern are included in the group. The first line (the line that matched the start pattern) does not need to match the `ContinueThrough` pattern. This is useful in cases such as a Java stack trace, where some indicator in the line (such as a leading whitespace) indicates that it is an extension of the proceeding line.
`halt_before`	All consecutive lines not matching this pattern are included in the group. This is useful where a log line contains a marker indicating that it begins a new message.
`halt_with`	All consecutive lines, up to and including the first line matching this pattern, are included in the group. This is useful where a log line ends with a termination marker, such as a semicolon.

Examples

"continue_past"

"continue_through"

"halt_before"

"halt_with"

multiline.start_pattern

required string literal

Regular expression pattern that is used to match the start of a new message.

Examples

"^[\\s]+"

"\\\\$"

"^(INFO|ERROR) "

";$"

The maximum amount of time to wait for the next additional line, in milliseconds.

Once this timeout is reached, the buffered message is guaranteed to be flushed, even if incomplete.

Examples

proxy

optional object

Proxy configuration.

Configure to proxy traffic through an HTTP(S) proxy when making external requests.

Similar to common proxy configuration convention, you can set different proxies to use based on the type of traffic being proxied, as well as set specific hosts that should not be proxied.

proxy.enabled

optional bool

Splat	`*` matches all hosts

region

optional string literal

The AWS region of the target service.

Examples

"us-east-1"

sqs

optional object

Configuration options for SQS.

sqs.client_concurrency

optional uint

Number of concurrent tasks to create for polling the queue for messages.

Defaults to the number of available CPUs on the system.

Should not typically need to be changed, but it can sometimes be beneficial to raise this value when there is a high rate of messages being pushed into the queue and the objects being fetched are small. In these cases, system resources may not be fully utilized without fetching more messages per second, as the SQS message consumption rate affects the S3 object retrieval rate.

Examples

sqs.delete_message

optional bool

Whether to delete the message once it is processed.

It can be useful to set this to false for debugging or during the initial setup.

default: true

sqs.poll_secs

optional uint

How long to wait while polling the queue for new messages, in seconds.

Generally, this should not be changed unless instructed to do so, as if messages are available, they are always consumed, regardless of the value of poll_secs.

default: 15 (seconds)

sqs.queue_url

required string literal

The URL of the SQS queue to poll for bucket notifications.

Examples

"https://sqs.us-east-2.amazonaws.com/123456789012/MyQueue"

Examples

"/path/to/host_certificate.crt"

sqs.tls_options.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.

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"

sqs.tls_options.verify_certificate

optional bool

Enables certificate verification.

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.

Relevant for both incoming and outgoing connections.

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

sqs.tls_options.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.

sqs.visibility_timeout_secs

optional uint

The visibility timeout to use for messages, in seconds.

This controls how long a message is left unavailable after it is received. If a message is received, and takes longer than visibility_timeout_secs to process and delete the message from the queue, it is made available again for another consumer.

This can happen if there is an issue between consuming a message and deleting it.

default: 300 (seconds)

tls_options

optional object

TLS configuration.

tls_options.alpn_protocols

optional [string]

Sets the list of supported ALPN protocols.

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

Examples

"/path/to/host_certificate.crt"

tls_options.key_file

optional string literal

How it works

AWS authentication

Vector checks for AWS credentials in the following order:

The auth.access_key_id and auth.secret_access_key options.
The AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables.
In Web Identity Token credentials from the environment or container (including EKS). These credentials will automatically refresh when expired.
ECS credentials (IAM roles for tasks). These credentials will automatically refresh when expired.
As entries in the credentials file in the .aws directory in your home directory (~/.aws/credentials on Linux, OS X, and Unix; %userprofile%\.aws\credentials on Microsoft Windows).
Using a named profile specified in the credentials file via the AWS_PROFILE environment variable.
The IAM instance profile (only works if running on an EC2 instance with an instance profile/role). Requires IMDSv2 to be enabled. For EKS, you may need to increase the metadata token response hop limit to 2. These credentials will automatically refresh when expired.

If no credentials are found, Vector’s health check fails and an error is logged.

Obtaining an access key

In general, we recommend using instance profiles/roles whenever possible. In cases where this is not possible you can generate an AWS access key for any user within your AWS account. AWS provides a detailed guide on how to do this. Such created AWS access keys can be used via auth.access_key_id and auth.secret_access_key options.

Assuming roles

Vector can assume an AWS IAM role via the auth.assume_role option. This is an optional setting that is helpful for a variety of use cases, such as cross account access.

Context

By default, the aws_s3 source augments events with helpful context keys.

Handling events from the `aws_s3` source

This source behaves very similarly to the file source in that it will output one event per line (unless the multiline configuration option is used).

You will commonly want to use transforms to parse the data. For example, to parse VPC flow logs sent to S3 you can chain the remap transform:

[transforms.flow_logs]
type = "remap" # required
inputs = ["s3"]
drop_on_error = false
source = '''
. = parse_aws_vpc_flow_log!(string!(.message))
'''

To parse AWS load balancer logs, the remap transform can be used:

[transforms.elasticloadbalancing_fields_parsed]
type = "remap" # required
inputs = ["s3"]
drop_on_error = false
source = '''
. = parse_aws_alb_log!(string!(.message))
.request_url_parts = parse_url!(.request_url)
'''

State

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

Transport Layer Security (TLS)

Vector uses OpenSSL for TLS protocols due to OpenSSL’s maturity. You can enable and adjust TLS behavior via the tls.* options and/or via an OpenSSL configuration file. The file location defaults to /usr/local/ssl/openssl.cnf or can be specified with the OPENSSL_CONF environment variable.
