Prometheus Setup – Vesta Lab

Prometheus collects metrics from exporters in the Vesta Lab and makes them available to Grafana.

Host Info

  • Node: docker-ve2
  • IP: 10.20.0.3
  • Port: 9090

1. Directory Structure

/opt/monitoring/prometheus/
├── prometheus.yml

2. Basic prometheus.yml

global:
  scrape_interval: 15s

scrape_configs:
  - job_name: 'prometheus'
    static_configs:
      - targets: ['localhost:9090']

  - job_name: 've1-proxmox'
    static_configs:
      - targets: ['10.10.0.2:9100']

  - job_name: 've2-proxmox'
    static_configs:
      - targets: ['10.10.0.3:9100']

3. Run Prometheus

docker run -d \
  --name=prometheus \
  -p 9090:9090 \
  -v /opt/monitoring/prometheus:/etc/prometheus \
  prom/prometheus

Result

Prometheus is collecting data from all node exporters and exposing metrics to Grafana.

Node Exporter Deployment – Vesta Lab

Node Exporter is installed on each Proxmox node to provide system-level metrics to Prometheus.

Installation (on each node)

docker run -d \
  --name=node-exporter \
  --net="host" \
  --pid="host" \
  --restart always \
  -v "/:/host:ro,rslave" \
  quay.io/prometheus/node-exporter:latest \
  --path.rootfs=/host
  • Node ve1: 10.10.0.2:9100
  • Node ve2: 10.10.0.3:9100

Result

Each node is exposing metrics to Prometheus on port 9100.

Grafana Configuration – Vesta Lab

Grafana is used as the main visualization layer on top of Prometheus metrics.

Host Info

  • Node: docker-ve2
  • IP: 10.20.0.3
  • Port: 3000
  • Default credentials: admin / admin

Deployment

docker run -d \
  --name=grafana \
  -p 3000:3000 \
  -v grafana_data:/var/lib/grafana \
  --restart=always \
  grafana/grafana-oss

️ Configuration Steps

  1. Access: http://10.20.0.3:3000
  2. Add Prometheus as data source: http://10.20.0.3:9090
  3. Import dashboard: Node Exporter Full (ID: 1860)

Result

Grafana is connected to Prometheus and visualizing node metrics.

Uptime Kuma – Service Monitoring Setup

Uptime Kuma is deployed in the Vesta Lab to monitor the availability of internal and external services via HTTP, TCP, and ICMP.

Host Info

  • Node: docker-ve2
  • IP: 10.20.0.3
  • Port: 8280
  • VLAN: 20 (services)

Deployment (Docker)

docker volume create uptime_kuma_data

docker run -d \
  --name uptime-kuma \
  -p 8280:3001 \
  -v uptime_kuma_data:/app/data \
  --restart=always \
  louislam/uptime-kuma:latest

Usage

  • Access: http://10.20.0.3:8280
  • Create monitors:
  • https://vault.vestasec.com
  • https://gitlab.vestasec.com
  • http://10.10.0.2:8006 (Proxmox VE1)
  • http://10.10.0.3:8006 (Proxmox VE2)

Result

Uptime Kuma is now monitoring the uptime and latency of lab services with visual dashboards and alerts.
