vector sink

The vector sink streams log events to another downstream vector source.

Configuration

  • Common

  type = "vector" # example, must be: "vector"
  inputs = ["my-source-id"] # example
  address = "92.12.333.224:5000" # example

How It Works

Environment Variables

Environment variables are supported through all of Vector's configuration. Simply add ${MY_ENV_VAR} in your Vector configuration file and the variable will be replaced before being evaluated.

You can learn more in the Environment Variables section.

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 thehealthcheck option to false.

Streaming

The vector sink streams data on a real-time event-by-event basis. It does not batch data.
