Install Vector on RHEL
Red Hat Enterprise Linux is a Linux distribution developed by Red Hat for the commercial market. This page will cover installing and managing Vector on the RHEL operating system.
Install
- Agent Role
- Aggregator Role
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.

Deployment
Vector is an end-to-end observability data platform 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:
Administration
Start
sudo systemctl start vector
Stop
sudo systemctl stop vector
Reload
systemctl kill -s HUP --kill-who=main vector.service
Restart
sudo systemctl restart vector
