CAST can enhance the system management of cluster-wide resources. It consists of the open source tools: cluster system management (CSM) and burst buffer.
Current name for Simple Event Correlator is logstash-filter-csm-event-correlator-*.gem this should be updated to be logstash-filter-cast-event-correlator-*.gem.
All references in the source need to be updated from csm to cast, as while the csm team worked on it CAST is a more general term for the future of the product.
