services for nodes, performs a global configuration of services on all nodes, runs a utility to create
the golden system image, and runs node-specific cluster configuration scripts on the head node.
The collectl utility collects data on the nodes of the HP XC system and plays back the information
as ASCII text or in a plot form. For more information, see The collectl Utility (page 69).
