rackspace-monitoring-agent

I suspect the project he's referring to is our monitoring agent: https://github.com/racker/virgo We're working on splitting this out into a reusable platform for writing lightweight host-based agents. Luvit works out fairly well for this - our monitoring agent runs in around 5mb resident memory, works on Windows (although we haven't released that yet) and is relatively easy to code on. Shameless plug: if this sort of stuff interests you, hit me up, my email is in my profile.

Rackspace use hundreds of open source projects. Luvit.io is specifically being used in our Host Monitoring Agent, which is open source and you can find here: https://github.com/racker/virgo This is used to collect all kinds of host metrics (CPU, disk, ram, custom scripts, mysql, etc) for the Cloud Monitoring Product.

We are using Luvit to build a monitoring agent using an async programming model. Using node was not an option given the memory consumption. https://github.com/racker/virgo That said there are some modules coming out of the community: https://github.com/luvit/luvit/wiki/Projects
