Information collection device, information collection program, and method

摘要

An information collection device acquires information from a plurality of devices connected through a network. The information collection device includes: a first addition unit that adds, for each of the devices, an information collection duration required to collect information of the devices to a communication duration required to communicate with the devices; a second addition unit that adds a maximum duration among the durations by addition of the first addition unit to a predetermined time to obtain a first time; a subtraction unit that subtracts the information collection duration of each of the devices from the first time; a first setting unit that sets a time obtained by the subtraction unit as a second time that is when information collection starts at each of the devices; and an acquisition unit that acquires information obtained by the information collection that starts at the second time.

1. An information collection device that acquires information from a plurality of servers connected through a network, comprising:
a computer processor, wherein the computer processor executes a process comprising: storing collection history information and collection item information for the plurality of servers; calculating, for each server of the plurality of servers, an estimated delay time of the server based on an average delay time of all collection items recorded in the collection history information of the server; calculating, for each collection item of a respective server, a frequency of change for the collection item by dividing a number of times the collection item has been acquired by a number of times the collection item has changed recorded in the collection item information of the respective server; adding, for each server of the plurality of servers, the estimated delay time of the server to a stored maximum collection duration, representing a longest duration of time required to collect a collection item from the server, to determine a notification duration; adding a longest notification duration of the determined notification durations of the plurality of servers to a current time to determine a data acquisition time; subtracting, for each collection item, a collection duration, representing a duration of time required to collect the collection item, from the data acquisition time to obtain and set a collection start time for the collection item; creating a collection schedule indicating the collection start time and a collection order of each collection item to collect from each server, wherein the collection order for each server is arranged based on the collection start times of the collection items and wherein collection items having the same collection start time are sorted in descending order of their frequency of change; and performing information collection from the plurality of servers based on the collection order, wherein the information collection for a particular collection item starts at the respective collection start time of the particular collection item.
