Forward metrics from your Prometheus instance
Collect metrics from your Prometheus instance using Vector and Prometheus Remote-Write .
1. Install
Select your platform:
Ubuntu • Debian
Configure the Vector APT repository and install Vector:
Install Vector
curl -1sLf \
'https://repositories.timber.io/public/vector/cfg/setup/bash.deb.sh' \
| sudo -E bash
apt-get install vector
2. Setup
Add a Prometheus source and a Better Stack sink to your /etc/vector/vector.yaml config:
vector.yaml
vector.toml
sources:
better_stack_prometheus_source_$SOURCE_TOKEN:
type: "prometheus_remote_write"
address: "0.0.0.0:9090"
transforms:
better_stack_prometheus_log_transform_$SOURCE_TOKEN:

.counter.value = del(.gauge.value)
del(.gauge)
}

Prometheus config file
remote_write:
- url: 'http://localhost:9090'
Reload the configuration of your Prometheus server:
Reload Prometheus server
ps -A | grep prometheus | tr -s ' ' | xargs | cut -f1 -d' ' | xargs kill -HUP
3. Restart
Restart Vector to reload the configuration:
Restart Vector
systemctl restart vector
You should see your metrics in the Prometheus dashboard .
Collect metrics from Prometheus exporters
Scrape metrics from your Prometheus exporters and applications using Vector .

Configure the Vector APT repository and install Vector:
Install Vector
curl -1sLf \

| sudo -E bash
apt-get install vector
2. Setup
Add a Prometheus source and a Better Stack sink to your /etc/vector/vector.yaml config.
Change endpoints in the source section to be an array of string URLs on which Vector can scrape metrics in the Prometheus format.
