It inquires of the CPU 115 to obtain the value of the CPU usage rate, and substitutes the obtained value for the temporary variable SharingRate.
In step 1903, the value of the temporary variable SharingRate is compared with the constant THRESHOLD. Step 190 if the value of the temporary variable SharingRate is greater than the constant THRESHOLD
Proceed to 4 and the value of the temporary variable SharingRate becomes the constant THRESHOL
In the case of D or less, the process proceeds to step 1905. Where the constant T
HRESHOLD is a threshold value for determining whether the load level of the service providing computer 102 is high or low. Step 1904
Then, the value heavy is substituted for the temporary variable Load, and the process proceeds to step 1906. In step 1905, the temporary variable Loa
The value light is substituted for d, and the flow advances to step 1906. In step 1906, the value of the temporary variable Load is returned to the load information monitoring program 107.

In the present embodiment, the CPU usage rate of the CPU 115 is used as a scale of the load level, but it is needless to say that another scale can be used. Specifically, a memory usage rate in the memory 112, a communication data amount per unit time in the communication interface 116, and the like can be used as a measure of the load level. In step 1902 in FIG. 19, the load level is determined based on the CPU usage rate. However, it is of course possible to determine the load level based on other measures such as the memory usage rate in the memory 112 or the number of communication connections in the communication interface 116. As described above, according to the information display method in the online system of the present embodiment, the operation status of the service providing computer is displayed on the screen of the terminal computer along with the service list information. This eliminates the need for unnecessary calls to a computer with a high load or a computer in which a service is not running.
