1. A computer-readable storage medium having instructions stored thereon that, when executed by a processor of a software-defined monitoring platform, cause the processor to perform operations comprising: monitoring event data associated with a network event that occurred within a virtualized IP software-defined networking network that is monitored by a virtualized software-defined monitoring resources platform, wherein the software-defined monitoring platform comprises the virtualized software-defined monitoring resources platform; measuring, based upon the event data associated with the network event, a quality of service performance metric associated with the virtualized software-defined monitoring resources platform, wherein the quality of service performance metric comprises an event packet loss metric that reflects a network event processing throughput for each event processor in the virtualized software-defined monitoring resources platform; determining, based upon the event packet loss metric of the quality of service performance metric, that an auto-scaling operation is to be performed on the virtualized software-defined monitoring resources platform that monitors the virtualized IP software-defined networking network, wherein the auto-scaling operation comprises reconfiguration of the virtualized software-defined monitoring resources platform that monitors the virtualized IP software-defined networking network; and in response to determining that the auto-scaling operation is to be performed, reconfiguring the virtualized software-defined monitoring resources platform that monitors the virtualized IP software-defined networking network by adding virtual machine capacity for supporting event management tasks.
