How It Works

Communication Protocol

Upstream Vector instances forward data to downstream Vector instances via the TCP protocol.

Context

By default, the vector source will augment events with helpful context keys as shown in the "Output" section.

Encoding

Data is encoded via Vector's event protobuf before it is sent over the wire.

Health checks

Health checks ensure that the downstream service is accessible and ready to accept data. This check is performed upon sink initialization. If the health check fails an error will be logged and Vector will proceed to start.

Require health checks

If you'd like to exit immediately upon a health check failure, you can pass the --require-healthy flag:

vector --config /etc/vector/vector.toml --require-healthy

Disable health checks

If you'd like to disable health checks for this sink you can set the healthcheck option to false.

Message Acknowledgement

Currently, Vector does not perform any application level message acknowledgement. While rare, this means the individual message could be lost.

State

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

Transport Layer Security (TLS)

Vector uses Openssl for TLS protocols for it's maturity. You can enable and adjust TLS behavior via the tls.* options.
