Abstract

An information processing includes a processor and monitors a plurality of operational servers to which processing is allocated. The processor determines an operational server on which failover will be performed in a failover test from among the plurality of operational servers in accordance with a number of the plurality of operational servers and a load, when a condition under which the failover test is conducted is satisfied, and issues a request to measure a failover time of the failover test that is conducted on the determined operational server.

Claims

1. An information processing device that monitors a plurality of operational servers to which processing is allocated, the information processing device comprising:

a processor configured to

determine an operational server on which failover will be performed in a failover test from among the plurality of operational servers in accordance with a number of the plurality of operational servers and a load, when a condition under which the failover test is conducted is satisfied, and

issue a request to measure a failover time of the failover test that is conducted on the determined operational server.

2. The information processing device according to claim 1, wherein

when the operational server stops, the processor postpones auto-scaling processing within the measured failover time.

3. The information processing device according to claim 2, wherein

the processor determines a number of operational servers in which a failure has occurred, when automatic failover is activated,

the processor calculates the failover time during which the auto-scaling processing is postponed in accordance with the determined number of operational servers and the failover time of the failover test, and

the processor postpones the auto-scaling processing within the calculated failover time.

4. The information processing device according to claim 1, wherein

the condition under which the failover test is conducted is a condition that the number of operational servers has changed after a previous failover test, a condition that a specified time period has passed after the previous failover test, or both thereof.

5. A failover time measurement method performed by an information processing device that monitors a plurality of operational servers to which processing is allocated by using a computer, the failover time measurement method comprising:

determining an operational server on which failover will be performed in a failover test from among the plurality of operational servers in accordance with a number of the plurality of operational servers and a load, when a condition under which the failover test is conducted is satisfied; and

issuing a request to measure a failover time of the failover test that is conducted on the determined operational server.

6. A non-transitory computer-readable recording medium having stored therein a failover time measurement program for causing an information processing device to execute a process, the information processing device monitoring a plurality of operational servers to which processing is allocated, the process comprising:

determining an operational server on which failover will be performed in a failover test from among the plurality of operational servers in accordance with a number of the plurality of operational servers and a load, when a condition under which the failover test is conducted is satisfied; and

issuing a request to measure a failover time of the failover test that is conducted on the determined operational server.
