+First of all, you need to create a dummy host, with IP ( localhost) and create the rule
+"Individual program call instead of agent access". The value for program call should be:
+
+~/local/share/check_mk/agents/special/pdu_rack_summary.sh
+
+The reason for the rule is that the agent should be run under the check_mk site user.
+This special agent takes data for all hosts that containes "pdu" in it and from it's alias
+will take the rack information.
+
+It is providing back the information via piggyback mechanism
