optional string literal

The AWS region to send STS requests to.

If not set, this will default to the configured region for the service itself.

Examples

"us-west-2"

auth.secret_access_key

required string literal

The AWS secret access key.

Examples

"wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"

Option	Description
`auto`	Automatically attempt to determine the compression scheme. The compression scheme of the object is determined from its `Content-Encoding` and `Content-Type` metadata, as well as the key suffix (for example, `.gz`). It is set to `none` if the compression scheme cannot be determined.
`gzip`	GZIP.
`none`	Uncompressed.
`zstd`	ZSTD.

endpoint

optional string literal

Custom endpoint for use with AWS-compatible services.

Examples

"http://127.0.0.0:5000/path/to/service"

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 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

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, users 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

Enables proxying support.

optional string literal

Proxy endpoint to use when proxying HTTP traffic.

Must be a valid URI string.

Wildcard domains	`.example.com` matches requests to `example.com` and its subdomains
IP addresses	`127.0.0.1` matches requests to `127.0.0.1`
CIDR blocks	`192.168.0.0/16` matches requests to any IP addresses in this range
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 should not be changed unless instructed to do so, as if messages are available, they will always be 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"

optional [string]

Sets the list of supported ALPN protocols.

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

sqs.tls_options.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"

sqs.tls_options.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"

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.

Examples

sqs.tls_options.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"

sqs.tls_options.verify_certificate

optional bool

Enables certificate verification.

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

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

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

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.

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.
The AWS credentials file (usually located at ~/.aws/credentials).
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.

If no credentials are found, Vector’s health check fails and an error is logged. If your AWS credentials expire, Vector will automatically search for up-to-date credentials in the places (and order) described above.

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. You can adjust TLS behavior via the tls.* options.
