acknowledgements

common optional object
Controls how acknowledgements are handled by this source.

acknowledgements.enabled

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 accept connections on. The address must include a port.
Examples 
"0.0.0.0:9090"

auth

optional object
Options for HTTP Basic Authentication.

auth.password

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

auth.username

optional string literal
The basic authentication user name.
Examples 
"${HTTP_USERNAME}"
"username"

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

Output

Metrics

counter

counter
A single value that can be incremented or reset to a zero value but not decremented.
* optional
Any tags present on the metric.

gauge

gauge
A gauge represents a point-in-time value that can increase and decrease. Vector’s internal gauge type represents changes to that value. Gauges should be used to track fluctuations in values, like current memory or CPU usage.
* optional
Any tags present on the metric.

How it works

Context

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

Metric type interpretation

The remote_write protocol used by this source transmits only the metric tags, timestamp, and numerical value. No explicit information about the original type of the metric (i.e. counter, histogram, etc) is included. As such, this source makes a guess as to what the original metric type was.

For metrics named with a suffix of _total, this source emits the value as a counter metric. All other metrics are emitted as gauges.

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.
