Up to now, Ruby's performance profilers that are able to measure execution time of each method have been developed. However, there is no real-time profiler that is able to show the profiling result while a Ruby program is running. We developed a profiler that is able to profile programs written in Ruby language in real time. The profiler can get execution time information of each method in the target Ruby program. It is able to get the information from a foreign host connected by network in real time. Furthermore, the profiler can profile associating each information with the entire call-path from an entry point of the program. With this call-path informathion users can know the trend in program performance in detail. The profiler consists of two parts: a profiling module and a monitor program. The profiling module collects information, and the monitor program provides information for users in real time. In this paper, we describe the design and implementation of our proposed profiler. We also describe the result of overhead evaluation for the profiler. Execution time increases 1.15 times in a practical example. We conclude that our profiler is capable for practical use.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"15","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌プログラミング（PRO）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2011-06-29","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"4"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:32:05.801345+00:00","id":74633,"links":{}}
