Hi, 

In terms of where the data will be coming from,  it will be coming from node-txstatsD, a port of statsD/node-statsD, a statsD client.  I had previously been working on using Event Emitters in conjunction with statsD, but node-txstatsD seems to solve the task of obtaining and sending timing to a visualization front-end. 

The data to be visualized will be timing (in ms), counts, and maybe  sizes(KB, MB). 

Based on this, what would be the recommended front-end to then visualize the information?

Hello,

The more important question is where will your data come from: event
logging? graphite? elsewhere? visualization comes secondary to this.

EventLogging is a good solution for structured, somewhat complex,
application data, graphite is s good solution for plain counters, which is
well suited to perf data. Let us know if you already have data and we can
proceed from there.

Thanks,

Nuria
