Steve Byrnes gave an excellent presentation on "Hadoop for DevOps, including OpenTSDB, Flume, and Scribe."
He also uploaded the slides and the materials using some fancy tools. In his own words,
"Hi, I've finally gotten the presentation pushed out to Github. See http://erewhon.github.io/hadoop-devops-prezi/ for the HTML w/presentation notes. The source for the presentation and the examples are at https://github.com/erewhon/hadoop-devops-prezi (Some of those examples might have a hard coded user or host in them, so probably shouldn't be run as is.)
