1. Understanding Xymon Architecture
Xymon consists of three main components:
1. Xymon Server (Big Brother Server) – The central monitoring system that collects and displays data.
2. Xymon Clients – Agents installed on monitored machines to send health and performance data.
3. Web Interface – A dashboard that provides a color-coded status overview.
2. Setting Up Xymon
A. Install Xymon Server (on Linux)
1. Update System Packages
sudo apt update && sudo apt upgrade -y # For Debian/Ubuntu
sudo yum update -y # For RHEL/CentOS
2. Install Required Dependencies
sudo apt install -y xymon apache2 rrdtool librrd-dev libpcre3-dev libssl-dev
3. Download and Install Xymon
wget https://sourceforge.net/projects/xymon/files/latest/download -O xymon.tar.gz
tar -xzf xymon.tar.gz
cd xymon-*
./configure --prefix=/opt/xymon
make && sudo make install
4. Start Xymon Server
sudo /opt/xymon/server/bin/xymon.sh start
5. Access Web Dashboard
Open a browser and go to http://<server-ip>/xymon
B. Install Xymon Client (on Monitored Machines)
1. Install Required Packages
sudo apt install -y xymon-client
2. Configure Client to Send Data to Xymon Server
Edit the configuration file:
sudo nano /etc/default/xymon-client
Set the XYMONSERVERS variable to point to the Xymon server’s IP:
XYMONSERVERS="192.168.1.100"
3. Restart the Client
sudo systemctl restart xymon-client
3. Understanding the Web Dashboard
Green = OK
Yellow = Warning
Red = Critical
