Abstract: The present invention provides a disk detection method and apparatus. The method includes: collecting a set of N pieces of real-time data that are in a one-to-one correspondence with N input/output I/O-related counters of a disk, where the N I/O-related counters include an I/O response time of the disk and a counter affecting the I/O response time; the I/O response time is a time between delivery of an operation request by an application and reception of a response of the disk to the request; determining, according to the N pieces of real-time data, whether the I/O response time is abnormal; and outputting a detection result if the I/O response time is abnormal, where the detection result is used to represent that the I/O response time is abnormal.

Abstract: A method and an apparatus for determining a leak of a program running resource are disclosed that relate to the field of computer applications. The method for predicting a usage condition of a program running resource includes collecting program running resource usage at least once within each program running resource usage period; decomposing the collected program running resource usage into different resource components; for data contained in each resource component, determining a prediction function for the resource component; determining an overall prediction function for a program running resource according to the determined prediction functions for all the resource components; and predicting a usage condition of the program running resource based on the determined overall prediction function.

Abstract: A slow-disk detection method is disclosed, the method includes: periodically performing sampling in a detection period; each time sampling is performed, obtaining a first delay of data reading or writing that is performed on a hard disk in current sampling, and a first-delay-related indicator value; determining a first range to which the first-delay-related indicator value belongs; and if the first range is full, calculating a first ratio of the first delay to an average delay in a range; and each time after one detection period ends and before a next detection period starts, if a quantity of all delay-related indicator values fall within all full ranges is greater than or equal to a second threshold, calculating an average value of first ratios; and if the average value of the first ratios is greater than or equal to a third threshold, determining that the hard disk is a slow disk.
