Unobservable node identification

A method, comprising:

• controlling monitoring on a set of monitored nodes, wherein each of the monitored nodes includes associated monitoring logic that includes processor-executable code, wherein the monitoring logic is configured to transmit node information while executing on processors, and wherein the monitoring on the set of monitored nodes includes receiving the node information from the monitoring logic of the set of monitored nodes;
• generating an agent inventory list such that the agent inventory list is a list of nodes that, based on the monitoring of the monitored node, are determined to have transmitted information from the associated monitoring logic during a particular time period;
• generating a total inventory list of the set of monitored nodes in a manner that is independent of the monitoring of the monitored nodes;
• and
• determining, via at least a meta-monitoring processor, unobservable node information that is associated with a set of unobservable nodes based on a comparison of the total inventory list with the agent inventory list.

A processor-readable storage medium, having stored thereon processor-executable code that, upon execution by at least one processor, enables actions, comprising:

• determining a total inventory list of a set of monitored machines in a manner that is independent of the monitoring of the monitored machines;
• determining an agent inventory list such that the agent inventory list is a list of machines that, based on the monitoring of the monitored machine, are determined to have been running monitoring logic during a particular time period;
• and
• determining unobservable machine information that is associated with a set of unobservable machines based on a comparison of the total inventory list with the agent inventory list.
