Not picking on this tool specifically but I see these sorts of things posted on HN a bit and I am struggling to understand the appeal. So genuine quesion: I can understand it is a fun task to build but what advantages does it bring in real world use? Is it just a novelty thing or do people use these sorts of tools and if so why and what advantages do they have over ssh/cli?

My sysadmin brain is always looking to reduce the dependencies and the attack surface. Ideally I want less services running on less ports. Less software to install, maintain and secure. As a result I stick to ssh and shell most of the time. Generally any admin tool that has big library dependencies (eg anything python, node.js or ruby) is on my shit list. I am a bit more sympathetic to Go because of the single static exe but otherwise I prefer plain old shell.

I understand historical graphs are nice to look at and time series data is one of the areas where web tools are a win. Though I am probably more likely to look at alerts based on triggers than watch a graph in real time. I don't understand what advantage tables of process stats in html offers over the same in the cli.
