Deploy and Host Victoria Monitoring Stack on Railway

VictoriaMetrics is a high-performance, cost-effective time series database and monitoring solution. This stack combines VictoriaMetrics for metric storage, vmagent for scraping Prometheus-compatible metrics from your applications, Grafana for visualization, and an auth proxy for secure external access—providing a complete observability platform.

About Hosting Victoria Monitoring Stack

Hosting VictoriaMetrics requires orchestrating multiple services: a time series database for storing metrics, a scraping agent to collect data from application endpoints, a visualization layer, and secure access controls. This template handles the complexity by pre-configuring service discovery between components using Railway's internal networking. VictoriaMetrics stores metrics with configurable retention, vmagent dynamically scrapes targets defined via environment variables, Grafana comes pre-provisioned with the VictoriaMetrics datasource, and a Caddy-based auth proxy secures external write/query access with API key authentication.

Common Use Cases

• Application Performance Monitoring (APM): Collect and visualize metrics from your Railway-hosted services to monitor response times, error rates, and throughput
• Infrastructure Observability: Track resource utilization (CPU, memory, disk) across your Railway services with customizable Grafana dashboards
• Multi-Environment Metrics Aggregation: Consolidate metrics from external services (on-premise, other cloud providers) via the auth proxy's remote write endpoint

Dependencies for Victoria Monitoring Stack Hosting

• VictoriaMetrics: High-performance time series database (Prometheus-compatible)
• Grafana: Industry-standard visualization and dashboarding platform

Implementation Details

The stack uses Railway's internal networking for secure service-to-service communication. Configure scrape targets via the SCRAPE_TARGETS environment variable:

SCRAPE_TARGETS=myapp:myapp.railway.internal:3000/metrics,api:api.railway.internal:8080/metricsFor external metrics ingestion, use the auth proxy with your API key:

prometheus.yml remote_write configuration

remote_write:

• url: https://YOUR_AUTH_PROXY_DOMAIN/api/v1/write headers: X-API-Key: your-api-keyExpose metrics from your applications using the Prometheus client library:

const client = require('prom-client'); client.collectDefaultMetrics();

app.get('/metrics', async (req, res) => { res.set('Content-Type', client.register.contentType); res.end(await client.register.metrics()); });## Why Deploy Victoria Monitoring Stack on Railway?

Railway is a singular platform to deploy your infrastructure stack. Railway will host your infrastructure so you don't have to deal with configuration, while allowing you to vertically and horizontally scale it.

By deploying Victoria Monitoring Stack on Railway, you are one step closer to supporting a complete full-stack application with minimal burden. Host your servers, databases, AI agents, and more on Railway.
