The Marionette Collective Components and Terminology

Nodes Physical servers being managed mcollective-0.4.7.noarch.rpm mcollective-common-0.4.7.noarch.rpm

Server mcollectived The ruby based daemon on every node mcollective-0.4.7.noarch.rpm mcollective-common-0.4.7.noarch.rpm

Agent service.rb Small ruby classes that manage services, packages, etc. Hosted by the mcollective-0.4.7.noarch.rpm server mcollective-common-0.4.7.noarch.rpm

Client Include MCollective::RPC Any component that sends requests to servers. mcollective-client-0.4.7.noarch.rpm mcollective-common-0.4.7.noarch.rpm

Collective Combination of nodes, servers, agents, middleware and clients

Connectivity Plugin Communication between all components. Many possible. rubygem stomp
