Analysis device and information processing system

An information processing system:

• comprising:
• an information processing device;
• and
• an analysis device including:
• a storage device configured to
• store therein performance information of each of plural subjects, each of the plural subjects being any type of performance of any device or any process in the information processing device, and
• a processor configured to
• acquire first performance information of a first subject of the plural subjects from the information processing device,
• compare the first performance information and a reference value with each other to calculate a variation rate, the reference value indicating performance information of the first subject previously stored in the storage device,
• store the first performance information in the storage device when the variation rate exceeds a predetermined variation rate,
• calculate a sampling rate for each of the plural subjects, the sampling rate indicating a ratio of a number of performance information stored in the storage device to a number of performance information acquired from the information processing device within a predetermined time period,
• determine analysis candidate subjects which have a sampling rate higher than a predetermined sampling rate, and
• analyze a relationship between performance information of the analysis candidate subjects on basis of the performance information stored in the storage device.

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

• acquiring first performance information of a first subject from an information processing device;
• comparing the first performance information and a reference value with each other to calculate a variation rate, the reference value indicating performance information of the first subject previously stored in a storage device configured to store therein performance information of each of plural subjects, each of the plural subjects being any type of performance of any device or any process in the information processing device, the first subject being one of the plural subjects;
• storing the first performance information in the storage device when the variation rate exceeds a predetermined variation rate;
• calculating a sampling rate for each of the plural subjects, the sampling rate indicating a ratio of a number of performance information stored in the storage device to a number of performance information acquired from the information processing device within a predetermined time period;
• determining analysis candidate subjects which have a sampling rate higher than a predetermined sampling rate;
• and
• analyzing a relationship between performance information of the analysis candidate subjects on basis of the performance information stored in the storage device.
