Abstract:
Transfer of desired monitoring data is enabled while restraining a data storage capacity and transfer capacity. A base system senses an alert and generates an index for specifying collection target data that is data present within a predetermined collection target time including an alert occurrence time point, records the collection target data in association with the index, into a time-series data table, and stores alert identification information in association with the index, into an index specifying table. A center system receives the alert identification information and transmits a data request for requesting the collection target data, to the base system. The base system, upon receipt of the data request, acquires the index associated with the designated alert identification information by searching the index specifying table, acquires the collection target data specified by the index from the time-series data table, and transmits the acquired data to the center system.
Abstract:
A time-series data management method for generating a histogram from time-series data using a computer provided with a processor and a storage device, the computer storing the time-series data including a time of day and a value in the storage device, storing section information including a start time, an end time, and an identifier of the time-series data in the storage device, generating the histogram from the time-series data corresponding to the section information and storing the generated histogram in the storage device, accepting a section to be searched and selecting the histogram associated with the section to be searched, and combining the selected histograms and generating a histogram for the section to be searched
Abstract:
A search system using a table search server and a file search server as transmission destination candidates for search queries, wherein search speed is assumed to be higher for a search in the form of file data than for table data, the table data is converted to file data and stored in the file search server. Created are a search query history management table for accumulating and depositing search query history, and a characteristic determination rule management table for managing the rules of determining that the search speed is higher for a search made in the form of file data than for table data. The search system applies the characteristic determination rules to the search query history and specifies the table data. The search system acquires the specified table data from the table search server, converts the data to file data, and stores the data in the file search server.
