Network Monitoring Intro

What is Network Monitoring?

Network monitoring is a critical process of tracking and analyzing network performance, security, and resource utilization. It involves continuously observing network traffic, devices, and connections to ensure optimal functionality and detect potential issues.

Key Components of Network Monitoring

1. Network Traffic Analysis

Network monitoring focuses on examining data packets traversing the network, including:

• Source and destination IP addresses
• Protocol types
• Bandwidth usage
• Packet loss rates

2. Device Performance Monitoring

Monitoring critical network device metrics:

• CPU utilization
• Memory consumption
• Interface status
• Response times

3. Security Surveillance

Basic Network Monitoring Tools in Linux

Using netstat

## Display active network connections
netstat -tuln

## Show network statistics
netstat -s

Using ss (Socket Statistics)

## List all TCP connections
ss -t

## Show detailed socket information
ss -tulnp

Challenges in Network Monitoring

1. High-volume data processing
2. Complex network architectures
3. Real-time performance tracking
4. Security and privacy concerns
