Getting back to work as a full time sysadmin was great, I got back to speed on scalability, updated my toolbox and learnt about other fantastic tools, like Graphite. Graphite is a graphing tool, extremely configurable and scalable. One thing, though, bothered me: the lack of good tools to send server metrics to it. I tried collectd graphite plugins and none did what I wanted the way I wanted.
So I decided to flex my node.js dev muscles and here is HoardD. This is a node.js app written in coffee-script that basically runs scripts and tools to get information about a server and sends it to carbon (Graphite’s storage backend). It’s easily expansible to include more metrics and very very fast and small (11MB or so, depending on scripts loaded, most of it is node).
