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?<p>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.<p>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.
Seems interesting, but I need to see some charts. I think I will use psdash + loadavg (<a href="http://loadavg.com/" rel="nofollow">http://loadavg.com/</a>). Until now I was using New Relic server monitoring.
How much load do tools like this add to the system. Ideally you want monitoring tools to be like using a voltmeter on an electronic circuit... display what's happening but adding very little influence of its own.
