Abstract

A method and system is described for monitoring the performance of a monitored server system using a polling server system. A single query is generated by the polling server system and transmitted to the monitored server system. The single query represents a request for a compilation of information about the performance of numerous services offered by a monitored server system. Upon receiving the single query, the monitored server system generates the compilation of information regarding the services it offers, and then transmits the compilation of information to the polling server system.
