本論文提出一套移動代理人監控系統之設計。此系統是以OSGi-Based Mobile Agent為對象,監控其移動及使用Service的狀態。我們利用廣泛建置的Email Servers的優勢,以及運行數十年Email System成熟的Protocol,將監控的內容透過Email Message的包裝,傳遞至系統指定的目的地,最後由系統將內容取出儲存。得到的監控資料讓我們知道提供移動代理人服務Server的狀態,也可供後續追蹤與分析,用於開發階段的問題追蹤及未來Servers的管理,都會有極大的幫助。We design a Mobile Agent Monitoring System. This system monitor the the state of transmitting and service-invoke of OSGi-Based Mobile Agent. We use a great amount of Email Servers build in the world, and mature Email System protocol which runs for decades, to package the monitoring contents in the Email Message, then delivered to the system specified destination, and finally system get and store the content from the destination Email Server. The monitoring information for mobile agents not only show the status of server which provide services , but also be the great help for the development stage of issue tracking and management of Servers with analysis the data.
