Why Use Cacti? 💡

Cacti is a great choice for network monitoring due to its scalability, flexibility, and ease of use. It allows you to:

  1. Monitor network traffic, device status, and performance metrics.
  2. Create custom graphs and dashboards.
  3. Alert on critical issues.
  4. Integrate with SNMP devices, making it versatile and compatible with various network equipment.

Prerequisites 📝

  • A Linux-based server (Ubuntu 18.04 or higher is recommended)
  • A SNMP-enabled network device
  • Basic Linux command line skills

Creating Your First Graph 📝

Now that you've installed Cacti, let's create a simple graph to monitor a device's network traffic:

  1. Access the Cacti web interface by navigating to your server's IP address in a web browser (e.g., http://192.168.1.1/cacti/).

  2. Configure the device you want to monitor by adding a new device template and device.

  3. Once the device is added, you can create a new graph by going to Graphs > New Graph. Select the device and graph type (e.g., Traffic Total), and save the graph.

  4. After saving the graph, you can edit it by clicking on the graph name. Add data queries to customize the graph as needed.
