Assistance in performing action responsive to detected event
View Patent ↗Assistance in performing an action for a detected event for a monitoring target resource whose connection is not an always-on connection to perform an appropriate action as soon as possible in response to occurrence of a failure.

calculating an index value for determining a level of probability of the occurrence pattern of the event;
determining whether the calculated index value is larger than a predetermined value; and
sending, to the device to perform the action, the occurrence pattern of the event the index value of which is determined to be larger than the predetermined value, and information related to the plural tasks and the action corresponding to the occurrence pattern.
8. The method according to claim 7 , further comprises sending information about time to erase the occurrence pattern of the event and the information related to the plurality of tasks and the action corresponding to the occurrence pattern.
9. The method according to claim 7 , further comprising:
determining whether each task fulfills a predetermined condition, and
counting a number of tasks determined by the condition determination section not to fulfill the predetermined condition, and
determining whether the number of tasks counted by the counting section is smaller than a predetermined value.
10. The method according to claim 7 , further comprising:
extracting a plurality of event sequences that occur within a given time period starting at a predetermined time,
acquiring, for each appearance pattern of an event, a frequency of appearance of the appearance pattern and a number of occurrences of each action containing the appearance pattern, and
multiplying the acquired frequency of appearance of the appearance pattern by the acquired number of occurrences of the action to calculate an index value.
11. The method according to claim 7 , further comprising:
receiving, from the assistance device, the occurrence pattern of the event and information related to the plurality of tasks and the action corresponding to the occurrence pattern,
storing, in a storage unit, the received occurrence pattern of the event and information related to the plurality of tasks and the action corresponding to the occurrence pattern,
specifying the occurrence pattern based on information related to the event that has occurred, and
performing an action based on information related to the action corresponding to the specified occurrence pattern.
