Patent ID: 7117531

Claim:
A computer monitoring system comprising a monitor computer for monitoring a computer and a plurality of monitor-subject computers to be monitored by said monitor computer, wherein: each one of said plurality of monitor-subject computers records logs of a use state of application software products, receives a log acquiring instruction from the monitor computer, reads out the recorded logs when said each one of the plurality of monitor-subject computers detects the log acquiring instruction, outputs and transmits them collectively to the monitor computer, and deletes the recorded logs from said each one of the plurality of monitor-subject computers; and said monitor computer outputs the log acquiring instruction to a specific monitor-subject computer when a log acquiring directive is input from a user of the monitor computer or automatically at a constant time, acquires said logs from said specific monitor-subject computer to which the log acquiring instruction is output in response to the log acquiring instruction, displays on a log displaying screen a log contents including input characters at said specific monitor-subject computer, further, when a directive for calculation and displaying of a use efficiency is input, calculates a using time which is a subtraction of idle state time that is a time period from a time point when a certain time has passed from an action of the application software products up to a next action, from a time when the application software products are activated up to the completion of the application software products, calculates the using time for each application software product, calculates a total idle state time in all the application software products, calculates a use rate for each of said application software products which is a rate of the using time of each application software product in total using time and the total idle state time of all application software products, a use rate of said idle state which is a rate of the total idle state time in total using time and the total idle state time of all application software products, and displays the use efficiency including the using time and the use rate for each of the application software products, and the total idle state time and the rate of the idle state.
