An event monitoring system includes a processor and a storage unit. The storage unit holds an event message including a character string related to an event occurring in an information system and guide information including one or more guides. The guide includes a guide message including a predetermined character string, notified in response to the event, and information regarding a coping method for the event. The processor compares the event message and the guide, associates the guide with the event in a case where the guide further includes information for identifying a variable portion of the guide message and a portion other than the variable portion of the guide message coincides with a portion other than a portion corresponding to the variable portion in the event message, and receives an input of information indicating a correct answer of a guide to be associated with the event in a case where the guide does not include the information for identifying the variable portion.

The present invention ensures improving responsiveness in a P2P type distributed database system that includes a plurality of node computers capable of storing management target data in storage devices. The storage devices include a first type storage device having a high input/output performance and a second type storage device having a low input/output performance. There is provided the storage devices that store KeySpace management tables including response count information indicative of a count of the node computers from which the identical management target data are to be read. The identical management target data are required to respond to a read request of the management target data. The node computers by a count indicated by the response count information and capable of storing the management target data in the first type storage devices among the plurality of node computers are determined as storage destinations when a CPU receives a write request of new management target data. The determined node computers are caused to store the management target data.

By selecting, as a monitoring API, an API which does not involve modifying information when executing a request, from APIs called by an AP to be monitored, transmitting a pseudo-request to the monitoring API, and receiving a response to the request, a monitoring node for determining whether or not the monitoring API is operating normally is created and is included in the AP.

Application operation monitoring apparatus and application operation monitoring method

A management system constructs management information indicating that log chunks and issue chunks extracted from a first system managing log information and issue information output by a process related to a first team for a program to be developed are linked. The management system searches, from the management information, a log message group compatible with a designated log message group that is one or more log messages related to the issue by log pattern matching using the designated log message group in a case of receiving an inquiry with which the designated log message group is associated from the second system. The management system displays, on the second system, a response containing a handling method represented by handling method information corresponding to the found log message group.

Inquiry response system and inquiry response method

A management computer manages first XaaS including a first node configuration and second XaaS including a second node configuration that is dependent on resources provided by the first XaaS. When a required resource amount which is required for the first XaaS in order to change the second node configuration is larger than a resource amount which can be provided by the first XaaS, the management computer determines a changed first node configuration which is capable of providing a resource amount equal to or larger than the required resource amount and, after changing the first XaaS to the determined changed first node configuration, changes the second node configuration of the second XaaS.
