MTRG has function monitors Simple Network Management Protocol (SNMP) network devices and gives illustration the traffic amount has through each interface. The mrtg-ping-probe is a ping probe for MRTG, which implementation to monitor the round trip time (RTT) and packet loss to seismic stations or servers. MRTG outputs function to generate graphs visualizing minimum and maximum RTT or packet loss. The seismic network monitoring system is developed using such software, and monitors the data traffic of the data acquisition servers and the IP line situations (i.e. RTT and packet loss) between the data center side and the observation station side end. In this paper, I describe concrete examples from actual operations, and show that this system is useful for maintenance of the seismographic network.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"＜論説＞","subitem_description_type":"Other"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"71612","nameIdentifierScheme":"WEKO"}],"names":[{"name":"UEHIRA, Kenji"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00032168","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11602838","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13426486","subitem_source_identifier_type":"ISSN"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute，University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"九州大学大学院理学研究院附属地震火山観測研究センター"},{"subitem_text_value":"Institute of Seismology and Volcanology, Faculty of Sciences, Kyushu University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"植平, 賢司"}],"nameIdentifiers":[{"nameIdentifier":"71611","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-12"}],"displaytype":"detail","filename":"14_001-012.pdf","filesize":[{"value":"1.8MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"14_001-012.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32177/files/14_001-012.pdf"},"version_id":"14204621-f339-4c78-b307-71e6d1eb5012"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"MRTG","subitem_subject_scheme":"Other"},{"subitem_subject":"SNMP","subitem_subject_scheme":"Other"},{"subitem_subject":"ping","subitem_subject_scheme":"Other"},{"subitem_subject":"RTT","subitem_subject_scheme":"Other"},{"subitem_subject":"packet loss","subitem_subject_scheme":"Other"},{"subitem_subject":"seismic data transmission","subitem_subject_scheme":"Other"},{"subitem_subject":"network monitoring","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"MRTGを用いた地震観測網の監視","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"MRTGを用いた地震観測網の監視","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4471","4472"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-05-15"},"publish_date":"2017-05-15","publish_status":"0","recid":"32177","relation_version_is_last":true,"title":["MRTGを用いた地震観測網の監視"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:07:51.564118+00:00"}
