1. A method of monitoring resources in a network of resources in a computing environment, comprising: constructing a topology model including event information for each resource in the network; storing user-defined queries for polling one or more of the topology models for event information wherein the resources need not be polled, and wherein each user-defined query includes a normal result set for the user-defined query; polling by executing one or more of the user-defined queries against one or more of the topology models to obtain corresponding polling query results; employing a processor to evaluate each polling query result in relation to the normal result set for the corresponding user-defined query to ascertain whether an event has resulted in a deviation from the normal result set; and presenting the evaluation results to a user to enable monitoring of the resources.
