Game Server Performance Monitoring with Grafana is a common requirement for VPS administrators. This guide provides practical instructions that you can follow on Ubuntu 22.04/24.04 or Debian 12, though most steps apply to other distributions as well.
Prerequisites
- A registered domain name (for public-facing services)
- Basic familiarity with the Linux command line
- Sufficient RAM for the game server (check requirements)
Server Installation
After applying these changes, monitor the server's resource usage for at least 24 hours to ensure stability. Tools like htop, iostat, and vmstat can provide real-time insights into system performance.
# Create a dedicated game server user
sudo useradd -m -s /bin/bash gameserver
sudo su - gameserver
# Install SteamCMD
mkdir -p ~/steamcmd && cd ~/steamcmd
curl -sqL "https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz" | tar zxvf -
# Install the game server
./steamcmd.sh +force_install_dir ~/servers/monitoring +login anonymous +app_update 1234567 validate +quit
The configuration above sets the recommended values for a VPS with 2-4GB of RAM. Adjust the memory-related settings proportionally if your server has different specifications.
Configuration File Setup
Performance benchmarks show that properly tuned monitoring can handle significantly more concurrent connections than the default configuration. The key improvements come from adjusting worker processes and connection pooling.
# Server configuration file
[Server]
ServerName=My monitoring Server
MaxPlayers=32
ServerPort=27015
Password=
AdminPassword=changeme
SaveInterval=300
These commands should be run as root or with sudo privileges. If you're using a non-root user, prefix each command with sudo.
Next Steps
With monitoring now set up and running, consider implementing monitoring to track performance metrics over time. Regularly review your configuration as your workload changes and scale resources accordingly.
