Abstract

A client terminal receives, in response to a boot command issued by a user to boot the client terminal, a first start command to start monitoring. The client terminal acquires first time information, repeatedly at certain time intervals from a basic software, and stores the first time information in a storage area. The client terminal receives a termination command to terminate the basic software. If the termination command is a command to terminate the basic software by using the basic software, the client terminal stores normal termination information in the storage area. When a second start command is received, and no normal termination information is stored in the storage area, the client terminal acquires second time information from the basic software and creates, depending on a result of comparison between the second time information and the first time information, log information relating to a termination of the basic software.

Claims

1. A non-transitory computer readable storage medium having stored therein a termination-log acquiring program that causes a computer to execute a process comprising:

receiving first start command information indicative of a command to start monitoring in response to a boot command issued by a user to boot the computer;
