Information processing device and information processing system

An information processing system, comprising:

• a plurality of computers;
• and
• an information processing device including:
• a memory;
• and
• a processor coupled to the memory and the processor configured to:
• record, in the memory, requests to the plurality of computers;
• determine, based on a past trend of requests and a specified maintenance-performing time, a time period in which maintenance is to be performed;
• stand by until the determined time period comes;
• determine, after standby, a maintenance standby time for each of the plurality of computers based on requests assigned to each of the plurality of computers, the maintenance standby time being a time between when a maintenance start instruction is issued to a time when the maintenance is started, the maintenance standby time determined by summing multiplication products of an average processing time for each of the requests multiplied by a number of the requests;
• determine, based on the maintenance standby time determined for each of the plurality of computers, an order in which maintenance is performed on the plurality of computers;
• and
• determine an order of maintenance such that maintenance is performed on the plurality of computers in ascending order of the maintenance standby time determined for each of the plurality of computers.

A non-transitory computer-readable recording medium having stored therein a program that causes a computer to execute a process, the process comprising:

• recording, in a memory, requests to a plurality of computers;
• determining, based on a past trend of requests and a specified maintenance-performing time, a time period in which maintenance is to be performed;
• standing by until the determined time period comes;
• determining, after standby, a maintenance standby time for each of the plurality of computers based on requests assigned to each of the plurality of computers, the maintenance standby time being a time between when a maintenance start instruction is issued to a time when the maintenance is started, the maintenance standby time determined by summing multiplication products of an average processing time for each of the requests multiplied by a number of the requests;
• and
• determining an order of maintenance such that maintenance is performed on the plurality of computers in ascending order of the maintenance standby time determined for each of the plurality of computers.
