I'm trying to monitor retention and want to query my decoders and concentrators for the date of the oldest event record. I know it's available through explore of the service but don't recall how to query it. Can I also use the rest interface?

Naushad (above) has also done a brilliant eLearning and eLab available for customers for a fee and to Internals at no charge - in case you want to learn more about REST. Use REST to pull stats, prove ROI, etc.
You can search Edutube for individual videos https://edutube.emc.com/html5/home.htm (keyword REST)or sign up for the course at RSA University at RSA University or just watch the "teaser" on YouTube RSA NetWitness - Introduction to the REST API - YouTube

Hope it helps!
