Abstract�� Grid monitoring toolkits was classified into three categories from the point the view of architecture and a novel architecture of grid monitoring, GSLMA(grid s ervice level monitoring architecture) was presented,which was based on SLA(serv ice level agreement). GSLMA was a SOA(service oriented architecture) with high flexibility and scalability. It supported third-party monitoring and cou ld be extended to monitor emerging grid services without much additional program ming. In the end, several key technologies were introduced in implementation of a test bed of GSLMA, such as: extending functionalities of the OGSA(open grid se rvice architecture) container, using WSLA(Web service level agreement) to descri be the monitoring information and etc.
Keywords�� grid monitoring and management   service oriented architecture   Web service leve l agreement
