Monitoring system for grid requires an easy solution for clusters location and registration. The paper describes discovery service for Java Management Extensions and Web Services based infrastructure monitoring system which solves this problem. System was designed and put into practice in existing installation of development grid in EU IST CrossGrid project. Described discovery service for Computing Elements didn’t affect the installation and operation of existing monitoring system. Durability, immunity to failures of clusters, and no additional firewall configuration requirements are the main features of the service. In Section 1 there is presented the concept of WS-based Global Discovery Service (WS-GDS). Section 2 presents features causing that this solution fits best to existing monitoring system based on WS and JMX. Section 3 contains WS-GDS sequence diagrams. Section 4 covers the implementation issues of GDS module. Section 5 sums up the advantages and disadvantages of accepted solution and compares it with the other systems and frameworks that could be used. The paper is ended with conclusions.
