Collector is a historical and point in time performance capture technology which collects configuration and performance data of servers and its components. It specifically applies to understanding physical or virtual server workload performance at an individual machine, cluster, or datacenter level.

The metrics collected derives useful data and gives you the ability to analyze performance at the individual host level, simulate the effect of combining hosts or clusters. Collector is non-invasive and will make no modifications to your environment. It only runs on clusters you choose and uses public APIs.
