There is a sequential connecting method that connects to a target server, starts monitoring commands and receives polling data periodically. This method cannot achieve large-scale and high-quality monitoring because common connection processes are slow. On the other hand, there is a connection pooling method that is fast because it decreases a connection process load. However, it consumes a large amount of memory. We propose a dynamic polling technology for large-scale and high-quality monitoring with a restricted memory. At first, it controls a monitoring frequency according to a state of the target server. Then it switches the connecting method to the target server by the sequential connecting method or the connection pooling method according to the monitoring frequency. As above, the proposed technology frequently monitors target servers only when they should be monitored. Therefore, we achieved a balance between quality and memory size on a large-scale server system monitoring.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"4","bibliographic_titles":[{"bibliographic_title":"研究報告データベースシステム（DBS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2009-07-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"18","bibliographicVolumeNumber":"2009-DBS-148"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":62537,"updated":"2025-01-22T02:35:45.607901+00:00","links":{},"created":"2025-01-18T23:24:28.493735+00:00"}
