Copying files from many nodes to one (aggregation or collection)

Relevant classes: any Suppose you have a centralized "master server" and you want to collect from all of the other clients a file. You need to run cfservd on every client. Use a cfagent.conf entry on the master like this to collect a file from the list. We use list iteration to accomplish this. control: actionsequence = ( copy ) list = ( aaaaa:bbbbbb:ccccccc:dddddd ) # Or.. # # list = ( SelectPartitionNeighbours(/home/mark/tmp/cfrun.hosts,#,random,4) ) # copy: /var/cfengine/database dest=/tmp/$(this)/filename server=$(list) Notice that the special variable $(this) holds the value of the current server during iterations.
