Install Vector via Nix

Nix is a cross-platform package manager implemented on a functional deployment model where software is installed into unique directories generated through cryptographic hashes, it is also the name of the programming language. This page will cover installing and managing Vector through the Nix package repository.

1. Your service logs to STDOUT
STDOUT follows the 12 factor principles.
2. STDOUT is captured
STDOUT is captured by your platform.
3. Vector collects & fans-out data
Vector collects data from your platform.

The agent role is designed to collect all data on a single host. Vector runs as a background process and interfaces with a host-level APIs for data collection. By default, Vector will collect logs from Journald via Vector's journald source and metrics via the host_metrics source, but it is recommended to adjust your pipeline as necessary using Vector's sources, transforms, and sinks.

  1. Install Vector

    nix-env --file --install --attr vector
  2. Configure Vector

  3. Start Vector

    vector --config /etc/vector/vector.toml
  4. Observe Vector

    vector top

Vector is an end-to-end observability data pipeline designed to deploy under various roles. You mix and match these roles to create topologies. The intent is to make Vector as flexible as possible, allowing you to fluidly integrate Vector into your infrastructure over time. The deployment section demonstrates common Vector pipelines:
