By using a single Hong Kong VPS to build your own monitoring system, you can achieve 24/7 global website monitoring at a very low cost. This tutorial will guide you step-by-step through setting up your own monitoring solution.
Why Choose Self-Built Monitoring?
Most mainstream SaaS monitoring services on the market (such as UptimeRobot, Pingdom, etc.) typically only support monitoring a few targets in their free versions, while paid versions are charged per monitored item, with costs increasing rapidly as the number of monitored items grows. Furthermore, all data is hosted on third-party platforms, raising privacy and security concerns.
The advantages of self-built monitoring are significant:
- Extremely low cost: A basic Hong Kong VPS (1 core, 1GB RAM) can easily monitor dozens of targets, with monthly costs only tens of yuan.
- Data autonomy: All monitoring data is stored on your own server, eliminating concerns about third-party data leaks.
- Powerful functionality: Open-source monitoring tools offer functionality comparable to commercial products, supporting multiple monitoring protocols such as HTTP(s), TCP, Ping, DNS, and SSL certificates.
- Unlimited scalability: Monitor as many targets as you want, without the limitations of SaaS services.
Why "Hong Kong VPS"?
The geographical location of monitoring nodes directly affects the accuracy and timeliness of monitoring. As an Asian network hub, Hong Kong offers very balanced access to mainland China, Southeast Asia, and even globally, making it an ideal location for deploying monitoring nodes.
The advantages of Hong Kong VPS include:
- No ICP filing required: Ready to use immediately, no need to wait for the ICP filing process.
- Latency balancing: Low latency for mainland China users (approximately 30-60ms for CN2 GIA lines), and reasonable latency for overseas users.
- Ample bandwidth: Hong Kong data centers have abundant international bandwidth resources, and monitoring requests are not throttled.
Recommended core tool: Uptime Kuma
Among many open-source monitoring tools, Uptime Kuma is currently the most popular choice on GitHub—as of 2026, it has received over 80,000 stars, indicating a highly active community.
Uptime Kuma Core Features
- Multi-protocol Monitoring: Supports HTTP/HTTPS, TCP ports, Ping (ICMP), DNS lookup, SSL certificate expiration detection, etc.
- 90+ Notification Channels: Supports email, DingTalk, Lark, WeChat Work, Telegram, Discord, Slack, Webhook, etc.
- Visual Dashboard: A beautiful and intuitive web interface that displays real-time status and response time trends for each monitored item.
- Extremely Low Resource Consumption: Runs smoothly on a 1-core, 2GB VPS, effortlessly monitoring dozens of targets.
- Open Source and Free: Based on the MIT license, completely open source, freely deployable and modifiable.
Besides Uptime Kuma, other open-source solutions such as Nezha and Coolmonitor are available, but Uptime Kuma offers the best overall performance in terms of ease of use and feature richness.
Complete Deployment Tutorial (One-Click Docker Installation)
The following tutorial is based on Debian/Ubuntu systems and takes approximately 10 minutes.
Step 1: Connect to the Server
Use an SSH tool (such as FinalShell, PuTTY, etc.) to connect to your Hong Kong VPS.
Step 2: Install Docker (Skip if already installed)
Update system packages
apt update && apt upgrade -y
Install Docker
curl -fsSL https://get.docker.com | bash
Start Docker and set it to start automatically on boot
systemctl start docker
systemctl enable docker
Step 3: Deploy Uptime Kuma
Execute the following command for one-click deployment:
docker run -d --restart=always -p 3001:3001 -v uptime-kuma:/app/data --name uptime-kuma louislam/uptime-kuma:1
Command explanation:
- `-d`: Run in the background
- `--restart=always`: Automatically start the container after the server restarts
- `-p 3001:3001`: Map port 3001 of the container to port 3001 of the server
- `-v `uptime-kuma:/app/data`: Persistently stores monitoring data.
Step 4: Access and Initialize
Access `http://yourserverIP:3001` in your browser.
On your first visit, you will be prompted to create an administrator account. Follow the instructions to fill in the username, password, and email address.
Step 5: (Optional) Binding the Domain and Enabling HTTPS
If you don't want to access via IP + port every time, you can configure a reverse proxy for your domain:
1. Resolve the domain name (e.g., `status.yourdomain.com`) to the server IP.
2. Configure a reverse proxy using Nginx or Caddy, pointing to `http://127.0.0.1:3001`.
3. Apply for a free Let's Encrypt SSL certificate and enable mandatory HTTPS.
Configuring Monitoring Items and Alerts
5.1 Adding a Monitoring Target
Log in to the Uptime Kuma backend and click "Add Monitoring Item":
- Monitoring Type: Select HTTP(s), TCP, Ping, or DNS, etc.
- URL/IP: Enter the website address or server IP to be monitored.
- Monitoring Interval: Recommended to be set to 60 seconds (the free version is sufficient and doesn't waste VPS resources).
- Timeout: Usually set to 5-10 seconds.
5.2 Configuring Notification Channels
Click "Settings" → "Notifications" and add the alert methods you need:
- Email: Configure SMTP to send email notifications when services are out of order.
- Telegram/Discord/Slack: Push real-time alerts via bot.
- DingTalk/Lark/WeChat Work: Suitable for domestic team collaboration scenarios.
- Webhook: Can be integrated with self-developed alert systems.
5.3 Create a Public Status Page (Optional)
Uptime Kuma supports creating a public status page to display the service status of all monitored items. Suitable for:
- Demonstrating service availability to users
- Serving as public proof of an enterprise service SLA
- Providing a unified view of all service status within the team
Advanced: Combined Monitoring Solutions
For more comprehensive monitoring, consider the Uptime Kuma + Beszel combination:
| Tools | Monitoring Content | Resource Consumption |
| Uptime Kuma | External Availability (Website, API, Port) | Approx. 80-120 MB RAM |
| Beszel | Server Internal Status (CPU, RAM, Disk, Network) | Hub approx. 10-50 MB, per Agent approx. 25 MB |
The combined memory consumption is only 150-180 MB, while Prometheus + Grafana requires 800+ MB for the same task. A 1GB Hong Kong VPS is more than sufficient.
Cost Comparison: Self-Built vs. SaaS
Taking monitoring 20 targets as an example, let's compare the annual costs:
| Plan | Monthly Cost | Annual Cost | Monitoring Limits | Data Ownership |
| UptimeRobot Free Version | $0 | $0 | Maximum 50 monitors, 10-minute intervals | Third-party |
| UptimeRobot Paid Version | ~$8 | ~$96 | Billed per monitored item | Third-party |
| Pingdom Basic Version | ~$15 | ~$180 | Billed per monitored item | Third-party |
| Self-Built (Hong Kong VPS) | ~$5-10 | ~$60-120 | Unlimited | Self-controlled |
An entry-level Hong Kong VPS (1 core, 1GB RAM) costs only a few tens of yuan per month, yet it can monitor an unlimited number of targets, and the data is completely self-controlled.** The self-built plan can recoup its cost in the first year, and saves money every year thereafter.
Why Choose Jtti Hong Kong VPS?
Building a monitoring system doesn't require a high-end VPS, but it does require high network stability and global reachability—if the monitoring nodes themselves have unstable networks, alerts will be distorted.
