Requirements

AWS Kinesis Firehose can only deliver data over HTTP. You will need to solve TLS termination by fronting Vector with a load balancer or configuring the tls.* options.

access_key

common optional string literal
AWS Kinesis Firehose can be configured to pass along an access key to authenticate requests. If configured, access_key should be set to the same value. If not specified, vector will treat all requests as authenticated.
Examples 
"A94A8FE5CCB19BA61C4C08"

acknowledgements

common optional object
Controls how acknowledgements are handled by this source. These settings override the global acknowledgement settings. This setting is deprecated in favor of enabling acknowledgements in the destination sink.

acknowledgements.enabled

common optional bool
Controls if the source will wait for destination sinks to deliver the events before acknowledging receipt.
default: false

address

required string literal
The address to listen for connections on
Examples 
"0.0.0.0:443"
"localhost:443"

record_compression

common optional string literal enum

The compression of records within the Firehose message.

Some services, like AWS CloudWatch Logs, will compress the events with gzip, before sending them AWS Kinesis Firehose. This option can be used to automatically decompress them before forwarding them to the next component.

Note that this is different from Content encoding option of the Firehose HTTP endpoint destination. That option controls the content encoding of the entire HTTP request.

Enum options string literal
OptionDescription
auto

Vector will try to determine the compression format of the object by looking at its file signature, also known as magic bytes.

Given that determining the encoding using magic bytes is not a perfect check, if the record fails to decompress with the discovered format, the record will be forwarded as-is. Thus, if you know the records will always be gzip encoded (for example if they are coming from AWS CloudWatch Logs) then you should prefer to set gzip here to have Vector reject any records that are not-gziped.

gzipGZIP format.
noneUncompressed.
default: text

tls

optional object
Configures the TLS options for incoming connections.

tls.ca_file

optional string literal
Absolute path to an additional CA certificate file, in DER or PEM format (X.509), or an in-line CA certificate 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, in DER or PEM format (X.509) or PKCS#12, or an in-line certificate in PEM format. If this is set, and is not a PKCS#12 archive, key_file must also be set. This is required if enabled is set to true.
Examples 
"/path/to/host_certificate.crt"

tls.enabled

optional bool
Require TLS for incoming connections. If this is set, an identity certificate is also required.
default: false

tls.key_file

optional string literal
Absolute path to a private key file used to identify this server, in DER or PEM format (PKCS#8), or an in-line private key in PEM format.
Examples 
"/path/to/host_certificate.key"

tls.key_pass

optional string literal
Pass phrase used to unlock the encrypted key file. This has no effect unless key_file is set.
Examples 
"${KEY_PASS_ENV_VAR}"
"PassWord1"

tls.verify_certificate

optional bool
If true, Vector will require a TLS certificate from the connecting host and terminate the connection if the certificate is not valid. If false (the default), Vector will not request a certificate from the client.
default: false

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 aws_kinesis_firehose source augments events with helpful context keys.

State

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

Forwarding CloudWatch Log events

This source is the recommended way to ingest logs from AWS CloudWatch logs via AWS CloudWatch Log subscriptions. To set this up:

  1. Deploy vector with a publicly exposed HTTP endpoint using this source. You will likely also want to use the parse_aws_cloudwatch_log_subscription_message function to extract the log events. Make sure to set the access_key to secure this endpoint. Your configuration might look something like:

     [sources.firehose]
 # General
 type = "aws_kinesis_firehose"
 address = "127.0.0.1:9000"
 access_key = "secret"

 [transforms.cloudwatch]
 type = "remap"
 inputs = ["firehose"]
 drop_on_error = false
 source = '''
 parsed = parse_aws_cloudwatch_log_subscription_message!(.message)
 . = unnest(parsed.log_events)
 . = map_values(.) -> |value| {
     event = del(value.log_events)
     value |= event
     message = del(.message)
     . |= object!(parse_json!(message))
 }
 '''

 [sinks.console]
 type = "console"
 inputs = ["cloudwatch"]
 encoding.codec = "json"

  2. Create a Kinesis Firewatch delivery stream in the region where the CloudWatch Logs groups exist that you want to ingest.

  3. Set the stream to forward to your Vector instance via its HTTP Endpoint destination. Make sure to configure the same access_key you set earlier.

  4. Setup a CloudWatch Logs subscription to forward the events to your delivery stream

Transport Layer Security (TLS)

Vector uses OpenSSL for TLS protocols. You can adjust TLS behavior via the tls.* options.
