address

required string literal
The address to listen for connections on, or systemd#N to use the Nth socket passed by systemd socket activation. If an address is used it must include a port.
Examples 
"0.0.0.0:8125"
"systemd"
"systemd#3"
Relevant when: mode = `tcp` or `udp`

connection_limit

optional uint
The max number of TCP connections that will be processed.
Relevant when: mode = `tcp`

keepalive

optional object
Configures the TCP keepalive behavior for the connection to the source.

keepalive.time_secs

optional uint
The time a connection needs to be idle before sending TCP keepalive probes.

mode

required string literal enum
The type of socket to use.
Examples 
"tcp"
"udp"
"unix"
Enum options string literal
OptionDescription
tcpTCP Socket.
udpUDP Socket.
unixUnix Domain Socket.

path

required string literal
The unix socket path. This should be an absolute path.
Examples 
"/path/to/socket"
Relevant when: mode = `unix`

receive_buffer_bytes

optional uint
Configures the receive buffer size using the SO_RCVBUF option on the socket.
Examples 
65536
Relevant when: mode = `tcp` or mode = `udp`

shutdown_timeout_secs

optional uint
The timeout before a connection is forcefully closed during shutdown.
default: 30 (seconds)
Relevant when: mode = `tcp`

tls

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

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.

default: false

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"

tls.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.

default: false

Outputs

<component_id>

counter

counter
A single value that can be incremented or reset to a zero value but not decremented.

How it works

Context

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

State

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

Timestamps

The StatsD protocol doesn’t provide support for sending metric timestamps. You may notice that each parsed metric is assigned a null timestamp, which is a special value indicating a realtime metric (i.e. not a historical metric). Normally, such null timestamps are substituted with the current time by downstream sinks or third-party services during sending/ingestion. See the metric data model page for more info.

Transport Layer Security (TLS)

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