Overview

This guide explains how to configure Glances to run automatically on system startup in web server mode on Ubuntu systems. Glances is a cross-platform system monitoring tool that provides a wealth of information about your system resources.

Prerequisites

  • Ubuntu 24.04 or similar
  • Glances installed via pipx
  • Administrative (sudo) access

Installation (If Not Already Done)

If you haven't already installed Glances:

# Install pipx if needed
sudo apt update
sudo apt install pipx
pipx ensurepath

# Install Glances
pipx install glances

Creating a Systemd Service

To make Glances start automatically on boot, you need to create a systemd service file.

Step 1: Create the Service File

sudo nano /etc/systemd/system/glances.service

Step 2: Add the Configuration

Add the following content to the file:

[!IMPORTANT] Replace YOUR_USERNAME with your actual username. The path must point to where Glances is installed by pipx.

[Unit]
Description=Glances in web server mode
After=network.target

[Service]
Type=simple
ExecStart=/home/YOUR_USERNAME/.local/bin/glances -w
Restart=on-failure
RestartSec=5s

[Install]
WantedBy=multi-user.target

Step 3: Enable and Start the Service

After creating and saving the service file, enable and start it:

sudo systemctl daemon-reload
sudo systemctl enable glances.service
sudo systemctl start glances.service

Step 4: Verify the Service Status

Check that the service is running correctly:

sudo systemctl status glances.service

You should see Active: active (running) if everything is working properly.

Troubleshooting

Common Issues

Error 217/USER

If you see an error like:

Active: activating (auto-restart) (Result: exit-code)
Process: XXXX ExecStart=/home/username/.local/bin/glances -w (code=exited, status=217/USER)

This indicates an issue with the User directive. The solution is to remove the User line from the service configuration.

Service Won't Start

Check the detailed logs to identify the issue:

journalctl -u glances.service

Wrong Path to Glances

If you installed Glances in a different location, update the path in the ExecStart line accordingly.

Accessing Glances Web Interface

Once the service is running, you can access the Glances web interface by opening a browser and navigating to:

http://localhost:61208

Or replace localhost with your server's IP address to access it from other devices on your network:

http://YOUR_SERVER_IP:61208

Advanced Configuration

Custom Port

To run Glances on a different port, modify the ExecStart line in the service file:

ExecStart=/home/YOUR_USERNAME/.local/bin/glances -w --port 8080

Additional Arguments

You can add any valid Glances command-line arguments to the ExecStart line:

ExecStart=/home/YOUR_USERNAME/.local/bin/glances -w --disable-plugin docker --time 2

Common arguments:

  • --time 2: Update frequency in seconds
  • --disable-plugin NAME: Disable a specific plugin
  • --disable-webui: Disable the web UI but keep the web server

Maintenance

Stopping the Service

sudo systemctl stop glances.service

Disabling the Service

To prevent Glances from starting on boot:

sudo systemctl disable glances.service

Viewing Logs

journalctl -u glances.service

Restarting After Configuration Changes

After modifying the service file:

sudo systemctl daemon-reload
sudo systemctl restart glances.service
