Network errors, such as dropped packets or retransmissions, can be mitigated by protocols like TCP/IP, which has remained foundational in networking due to its error-compensating capabilities. Despite this, understanding network errors is crucial for maintaining service performance and connectivity. Common network issues include network collisions, checksum errors, full queues, time-to-live exceeded errors, and packet retransmissions. Tools like ifconfig, netstat, ethtool, tcpretrans, tcpdump, and Wireshark are essential for diagnosing these problems. Effective network monitoring involves tools that automatically track performance baselines, alert users to anomalies, and provide insights into service availability and responsiveness. Dynatrace is highlighted as a comprehensive solution for network monitoring, offering insights into service health, user impact, and root causes of connectivity issues. The complexity of modern network infrastructures, including virtual environments, adds additional challenges to monitoring efforts, underscoring the importance of robust analytical tools.
