Heroku Logplex

Collect logs from Heroku’s Logplex, the router responsible for receiving logs from your Heroku apps

status: beta role: aggregator delivery: at-least-once egress: batch state: stateless output: log previously known as: logplex
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:

[sources.my_heroku_logs_source]
+type = "heroku_logs"
-type = "logplex"

acknowledgements

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

Warning

Disabling this option may lead to loss of data, as destination sinks may reject events after the source acknowledges their successful receipt.
default: false

Examples
"0.0.0.0:80"
"localhost:80"

auth

optional string literal
The basic authentication password.
Examples
"${HTTP_PASSWORD}"
"password"

auth.username

optional string literal
The basic authentication user name.
Examples

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 whose length is encoded in a header.

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

tls.key_pass

optional string literal
Pass phrase used to unlock the encrypted key file. This has no effect unless key_file is set.

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.
