Technically, traceroute is the most advanced, using various protocols like TCP, UDP, and ICMP to find the correct route, while tracepath only implements UDP.
Traceroute and tracepath are two Linux network tools that show the route to a destination, and are thus used to troubleshoot routing issues on Linux. Linux network monitoring is thus made of both, basic apps, mostly CLI-based, and large, fairly more complex and advanced, network monitoring and network traffic monitoring systems. Especially in small networks or as the first steps in troubleshooting, basic monitoring Linux tools can give initial insights. Most of these small Linux network tools are the base for many larger ones, and suitable for quick checks or automation of specific monitoring duties in absence of a more complete monitoring solution. These are basic tools, which cannot replace a fully-fledged network monitoring software that supports infinitely more devices, checks, and operating systems. As is traditional for Linux systems, a good number of CLI applications are available for free to do some network monitoring tasks. The metrics that are collected are the same, but the methods to collect them differ. Network monitoring for Linux is not vastly different from any other operating system. As this operating system is the de-facto standard on the majority of servers, enterprise networks, and cloud services, Linux network monitoring is an important area for any network administrator to focus on. Linux network monitoring deals with checking, analyzing, reporting, and optimizing Linux-based networks.
