Nakul’s Status Report for 4/23

This week I worked on collecting OS metrics from our node video server. I had to test different APIs and modules to collect these metrics since some modules were not configured with our particular server deployment. Used node-OS-module to retrieve metrics on CPU usage and network IO. I found later that the node-OS-module netstat was not supported with my OS and so I tested it on different platforms including virtual andrew linux machine as well our deployed EC2 instances. Since this approach was not working for our video server, I started looking into linux netstat which logs metrics on network IO. I was not able to find an API that allowed for easy collection of network IO metrics and thus I finally started looking AWS CloudWatch which is Amazon’s custom metric logging tool for servers deployed on EC2. CloudWatch has a package to retrieve metrics from node servers which I will be using to fetch network IO metrics. the tradeoff of using CloudWatch is that it only allows us to collect these metrics every 1 minute as compared to collecting them every time a response is sent from the video server. This week I will be working on finishing up this metric collection as well as developing a system to visualize our User simulation data.
