Receives log data from Heroku log drains via Heroku’s logplex system.

Alias

This component was previously called the logplex source. Make sure to update your Vector configuration to accommodate the name change:

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.

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

address

required string literal
The socket address to listen for connections on.
Examples
"0.0.0.0:80"
"localhost:80"

auth

optional object
HTTP Basic authentication configuration.

auth.password

required string literal
The password for basic authentication.
Examples
"hunter2"
"${PASSWORD}"

auth.username

required string literal
The username for basic authentication.
Examples
"AzureDiamond"
"admin"

decoding

optional object
Configures how events are decoded from raw bytes.

decoding.codec

optional string literal enum
The codec to use for decoding events.
Enum options
OptionDescription
bytesUses the raw bytes as-is.
gelfDecodes the raw bytes as a GELF message.
jsonDecodes the raw bytes as JSON.
native

Decodes the raw bytes as Vector’s native Protocol Buffers format.

This codec is experimental.

native_json

Decodes the raw bytes as Vector’s native JSON format.

This codec is experimental.

syslog

Decodes the raw bytes as a Syslog message.

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

default: bytes

framing

optional object

Framing configuration.

Framing deals with 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.

Options for the character delimited decoder.
Relevant when: method = "character_delimited"
The character that delimits byte sequences.

The maximum length of the byte buffer.

This length does not include the trailing delimiter.

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 (e.g. split between messages or stream segments).
character_delimitedByte frames which are delimited by a chosen character.
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
Options for the newline delimited decoder.
Relevant when: method = "newline_delimited"

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"
The maximum length of the byte buffer.

query_parameters

optional [string]

A list of URL query parameters to include in the log event.

These will override any values included in the body with conflicting names.

Array string literal
Examples
[
  "application",
  "source"
]

tls

optional object
Configures the TLS options for incoming/outgoing connections.

tls.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.

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.enabled

optional bool

Whether or not to require TLS for incoming/outgoing connections.

When enabled and used for incoming connections, an identity certificate is also required. See tls.crt_file for more information.

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"

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.

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 heroku_logs source augments events with helpful context keys.

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.
