摘要： A computer system includes a first computer and a second computer. The second computer includes, a minimum analysis dataset in which a data item serving as an analysis target and a repetition unit are defined in advance for each analysis target and an agent. The agent receives an analysis target data fetching designation including the minimum analysis dataset, a repetition range of repeating acquisition of data, and a repetition unit. The agent generates a first process that acquires data from the first computer and a first instance that executes processing within the first process on the basis of the repetition range and the repetition unit and activate the first instance to acquire the accumulated data from the first computer. When the processing of the first instance is completed, the agent generates a second process that executes analysis processing and a second instance that executes processing within the second process.

摘要： A computer system comprises a computer being coupled to a device via a device interface. The device interface has an error status register and a link status register. An error isolation unit periodically obtains values of the error status register and the link status register. The error isolation unit determine whether an error occurs in the device; determine whether the error is an error to be isolated; determine whether the error is an error to be isolated based on values of the error status register and the link status register re-obtained after elapse of a predetermined time in a case of determining the error is not to be isolated. The error isolation unit detects the error as an error of a protocol caused by stop of a power supply in a case of determining the error is to be isolated.
