1. A method of preventing event indication storms in a network having a Common Information Model server, the method comprising: a computer configured as the Common Information Model server, wherein the Common Information Model server includes elements related to each other at levels forming an indication class hierarchy, the indication class hierarchy having higher levels and lower levels and wherein the Common Information Model server generates and delivers indications of an event to a listener process for all instances including the higher levels and the lower levels in a period of time, and wherein a number of indications of interest generated and delivered in the period of time comprises an indication storm; the computer receiving, from the listener process, a specific top level indication class in the indication class hierarchy, wherein the specific top level indication class corresponds to one or more of the higher levels; the computer detecting an object behavior change in an information model, wherein the object behavior change corresponds to an event; the computer determining that the event corresponds to the specific top level indication class in the indication class hierarchy; and the computer, responsive to determining that the event corresponds to the specific top level indication class in the indication class hierarchy, generating and delivering an indication of interest to the listener process only for the one or more of the higher levels in the period of time, so that the number of indications of interest generated and delivered in the period of time does not comprise an indication storm.
