Introduction#

As a VPS user, we often face the following questions:

• Is the server running normally?
• How is the traffic usage?
• Is the server offline?
• Is the system resource usage reasonable?

Nezha Monitoring is a lightweight server monitoring tool that not only monitors server status in real-time but also sends alert notifications through various methods. This article will detail how to use Nezha Monitoring to monitor and alert VPS, and push alerts via WxPusher.

I. Nezha Monitoring Installation Steps#

1. Preparation#

First, you need to prepare a server as the monitoring panel, the VPS to be monitored, and a domain name pointing to the server IP.

2. Install Docker, Docker-Compose, and NPM Reverse Proxy#

1. Log in to the monitoring panel server and execute the following command to install Docker, Docker-Compose, and NPM reverse proxy in one click:

1
sudo apt install git -y && git clone https://github.com/slobys/npm.git && cd npm && chmod +x npm.sh && ./npm.sh

2. Install the monitoring panel:

1
curl -L https://raw.githubusercontent.com/nezhahq/scripts/refs/heads/main/install.sh -o nezha.sh && chmod +x nezha.sh && sudo ./nezha.sh

3. Reverse Proxy Configuration#

1. Open the NPM management panel Access the NPM management panel in the format of server IP: port

2. Add reverse proxy

[!NOTE] You can skip adding SSL first, select “None” in the SSL section, and access the Nezha panel using HTTP first. After confirming the panel is accessible, you can apply for and add SSL. Some users may encounter internal errors if the default port is not used during NPM installation. You can just press Enter all the way during NPM installation.

4. Install Agent#

1. Open the Nezha panel via domain name
2. Click the installation command, paste it into the VPS to be monitored for installation, then refresh the Nezha panel.

II. Monitorable Items#

• CPU Usage: Monitor CPU load in real-time
• Memory Usage: Monitor memory usage to avoid insufficient memory
• Disk Usage: Monitor disk space to prevent service exceptions due to full disk
• Network Traffic: Monitor inbound and outbound traffic to detect abnormal traffic in time

2. Service Status Monitoring#

• Website Status: Monitor website accessibility and response time
• Port Status: Monitor whether specified ports are open
• Process Status: Monitor whether critical processes are running

3. Network Status Monitoring#

• Latency Monitoring: Monitor server response time
• Offline Monitoring: Alert immediately when the server goes offline
• Network Jitter: Monitor network stability
