chef exec ruby get_data.rb --orgs org1,org2 --node-threshold 45 --knife-config /home/myuser/.chef/knife.rb

The script will put JSON reports in an output directory in the same directory as the script.

• <org>_<threshold_num>d_stale_nodes.json - Nodes in that org that have not checked in for the number of days specified.
• <org>_cookbook_count.json - Number of cookbook versions for each cookbook that that org.
• <org>_unused_cookbooks.json - A list of cookbooks and version that do not appear to be in-use for that org. This is determined by checking the versioned run list of each of the nodes in the org.

• --orgs -> A comma separated list of orgs to process
• --all-orgs -> Processes all orgs on the chef server. Setting this will override the --orgs setting
• --node-threshold -> Takes an integer specifying the number of days since last checkin to mark a node as stale.
• --knife-config -> A path to the knife config for the script to use. If using --all-orgs, this must be the pivotal user. If processing multiple orgs, must be pivotal or another user that can access all the specified orgs.
