Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention discloses a monitoring method of an I/O system, which is shown in a combined figure 1 and comprises the following steps:

step 101: read and write operations in the I/O system are monitored.

In this step, monitoring of read/write operations in the I/O system is implemented, where an upper layer application needs to perform read/write operations on data at different levels in the I/O system when performing read/write operations through a lower layer I/O system, where the I/O system specifically includes an upper file system layer and a lower drive layer, for example, the file data may be read/written first at the file system layer, and finally the read/write operations on the hardware storage device are implemented at the drive layer through a drive program, where monitoring of read/write operations in the I/O system may be monitoring of operations of each read/write operation in different structural levels of the I/O system, monitoring of read/write operations in different structural levels or division levels of the I/O system, so as to better find possible problems.

Step 102: and selecting target read-write operation from the read-write operation through a preset sliding statistical window.

The sliding statistical window has a set length and slides forward along with time or the number of read-write operations and other set parameters, so as to intercept a certain amount of read-write operations from all the generated read-write operations as target read-write operations and perform problem search according to the target read-write operations, for example, the target read-write operations may be the latest generated read-write operations intercepted by the sliding statistical window or the read-write operations generated within a latest period of time.

The target read-write operation is selected once when the sliding statistical window slides once, the target read-write operation is selected from the read-write operation through the set length of the sliding statistical window, the target read-write operation is selected once when the sliding statistical window slides once, and new target quantity is continuously obtained along with the change of the read-write operation so as to carry out real-time monitoring and analysis.

Step 103: and based on the target read-write operation, performing abnormal information feedback when the I/O system is abnormal.

The target read-write operations are selected read-write operations through a sliding statistical window from a plurality of generated read-write operations, and based on the target read-write operations, information such as read-write data volume, response time, occupied resource size and the like of the target read-write operations can be correspondingly analyzed, so that corresponding information feedback is realized when an I/O system is abnormal, the system or upper-layer application or a user is helped to quickly locate and find the problem of the I/O system, the problem is better solved, and the overall performance of the system is improved.

The abnormal information feedback process specifically includes that a warning is sent or a user selects to process when the I/O system is abnormal, so that the intelligence degree and the use experience of the system can be improved, developers can be helped to quickly locate problems related to the I/O system, and further processing and optimization are carried out according to specific problems.

The monitoring method of the I/O system in the embodiment of the invention monitors the read-write operation in the I/O system; selecting target read-write operation from the read-write operation through a preset sliding statistical window; based on the target read-write operation, abnormal information feedback is carried out when the I/O system is abnormal, the problem of the I/O system is quickly positioned and found, the intelligent degree of the system is improved, possible directions are provided for further problem positioning and optimization, the overall performance of the system is improved, and the use experience of the system is improved.

In a first aspect, as a preferred implementation manner, the step of selecting a target read/write operation from the read/write operations through a preset sliding statistic window includes:

in the file system layer of the I/O system, the read-write operation of the file data in the process of the upper application in the time sliding window is selected as the target read-write operation through the time sliding window with a set time length.

The selection of the target read-write operation is performed in a file system layer of an I/O system, and currently, for example, in a mobile terminal such as a mobile phone, when the system is implemented, each upper layer application is implemented as each process in an operating system, and each process needs to read and write file data through the file system when reading and writing the file data, so that the read-write operation of each process in a latest period of time can be statistically monitored in the file system, for example, the read-write data amount corresponding to the read-write operation or the corresponding time is statistically monitored.

The time sliding window has a set time length, and slides forwards along with the increase of time, so that different read-write operation sets are continuously intercepted and obtained along with the increase of time through the set time length, and a target read-write operation is obtained.

Preferably, the deadline of the time sliding window is the current time, and when the time of the time sliding window enters the next time from the current time, the time sliding window is also slid, and the latest occurring time is the deadline, the read-write operation occurring within the set time length is selected, so as to obtain the target read-write operation, and ensure the real-time performance and the accuracy of the detection of the I/O system problem.

Correspondingly, as a preferred embodiment, the step of performing exception information feedback when the I/O system has an exception based on the target read-write operation includes:

counting read-write data quantity corresponding to the read-write operation on the file data in the process of each upper-layer application in the target read-write operation; sequencing the processes of the upper-layer applications according to the read-write data volume obtained by statistics and obtaining a sequencing result; and when the upper management system prompts the I/O system to be abnormal, reporting the sequencing result.

The main objective of monitoring the file system level in the I/O system is to find and record the current applications that may affect the I/O performance of the system, in the process, after a target read-write operation is obtained through a set time sliding window selection, specifically, statistics is performed on the read-write data amount corresponding to the read-write operation of the file data by the process of each upper layer application in the target read-write operation, the read-write data amount is used to feed back the amount of the storage system resources occupied by the upper layer application corresponding to each process, and the upper layer management system preliminarily considers that the I/O system is abnormal under necessary conditions (for example, it is determined that the foreground application is stuck through an excessively long operation reaction time), at this time, the upper layer management system may obtain the information of the applications from the file system level of the I/O system through a specific communication mode, when information feedback is performed according to the abnormal condition of the I/O system prompted by the upper management system, the sorted result is specifically reported to the upper management system in the mobile terminal, so that the upper management system further performs corresponding processing on the processes by using a specific strategy according to the sorted result, for example: the processes of other background applications besides the system application, the foreground application and the white list application are killed directly.

Specifically, the above process may be implemented as follows, in which the read-write activity of each process in the latest period T is monitored:

a time sliding window with the time length of T is realized, and the length of T can be customized according to the situation as the time slides forwards; counting and sequencing read-write data quantity of each process in a time sliding window (old read-write data quantity beyond the sliding window is subtracted during counting, only read-write data quantity in the time sliding window is counted), judging that the situation that a foreground application is blocked and the like by an upper management system prompts that the I/O system is possibly abnormal, reporting sequenced process information to the upper management system when the processes are acquired, so as to solve related problems and realize quick positioning and solution of the I/O system abnormity.

In conjunction with fig. 2, there are 4 processes that have recently performed read and write activities (in the figure, a circle represents one read and write activity, a solid circle represents outside the statistical range of the sliding window, and a dotted circle represents inside the statistical range of the sliding window), and for the sake of simplifying the example, we assume that the data volume of each read and write activity is the same. According to the description of the implementation method, only the read-write activities in the sliding window are counted, and sequencing is performed according to the read-write data volume of each process. It can be seen that process 1 is not within the statistical range because the read and write activities are beyond the statistical range of the sliding window. The results of other processes after sequencing according to the read-write data quantity are as follows: process 3> process 2> process 4.

In a second aspect, as another preferred embodiment, the step of selecting a target read/write operation from the read/write operations through a preset sliding statistic window includes:

in the drive layer of the I/O system, selecting the read-write operation generated in the storage device in the read-write frequency sliding window as a target read-write operation through a read-write frequency sliding window with set read-write frequency.

The target read-write operation is selected to be performed in a drive layer of the I/O system, and currently, the storage devices of the mobile terminal systems such as a mobile phone and the like have corresponding drives to access the storage devices, so that the read-write performance of each read-write operation can be counted in a drive program, the change condition of the read-write performance of the devices is monitored, and the process of monitoring the abnormal information of the low-layer storage devices in the I/O system is realized.

The read-write times sliding window has set read-write times, and slides forwards along with the increase of the read-write times, so that different read-write operation sets are continuously intercepted and obtained along with the increase of the read-write operations occurring in the storage device through the set read-write times, and the target read-write operations are obtained.

Preferably, the last read-write operation in the read-write frequency sliding window is the latest read-write operation, when the read-write operation enters the next new read-write operation from the current read-write operation, the read-write frequency sliding window slides along with the current read-write operation, the latest read-write operation is taken as the last read-write operation in the window, the read-write operation occurring in the set read-write frequency is selected, the target read-write operation is obtained, and the real-time performance and the accuracy of the detection of the I/O system problem are ensured.

Correspondingly, on the one hand, as a preferred implementation manner, the step of performing exception information feedback when the I/O system has an exception based on the target read-write operation includes:

continuously acquiring the read-write performance corresponding to each read-write operation in the target read-write operation along with the sliding of the read-write frequency sliding window; according to the read-write performance, the average read-write performance of the target read-write operation selected in the read-write frequency sliding window is counted; if the average read-write performance is continuously lower than a first performance value within a set time length, determining that a storage device in the I/O system is abnormal; and reporting the information that the storage device has abnormity.

In the process, once per sliding of the read-write frequency sliding window, the selected target read-write operation changes, wherein the latest read-write operation is added, the read-write operation which occurs for the longest time in the original window is discarded, and in the process of performing abnormal information feedback when the I/O system is abnormal according to the target read-write operation selected from the read-write frequency sliding window, the read-write performance corresponding to each read-write operation in the target read-write operation needs to be acquired with each sliding of the read-write frequency sliding window, that is, preferably, the acquisition operation of the read-write performance corresponding to each read-write operation in the target read-write operation is executed once per new read-write operation in the memory device. Specifically, the obtaining of the read-write performance may be calculating the read-write rate of the read-write operation, calculating the response time of the read-write operation, calculating the delay time of the read-write operation, and the like, so as to achieve the evaluation and obtaining of the read-write performance.

And calculating to obtain average performance based on the read-write performance corresponding to each read-write operation in the target read-write operation, if the average performance obtained by continuous calculation and statistics along with the sliding of the read-write frequency sliding window is lower than a set first performance value, determining that the memory device in the I/O system has an abnormality, and specifically reporting an abnormality message to an upper management system to solve related problems and realize quick positioning and solving of the abnormality of the I/O system.

Specifically, the main monitoring target of the drive level is to find the read-write performance of the memory device is abnormal, and monitor the process of the change situation of the read-write performance of the memory device, and it is normal for the performance fluctuation which occurs in a short time occasionally due to the internal processing requirement of the device, but if the read-write performance fluctuates greatly continuously or the average performance is far lower than the normal value, and the device is recovered within a set time, that is, if the performance is continuously lower than the first performance value within a set time, it is considered that the device is abnormal and a warning message is sent to the upper management system, and the upper management system can prompt the user that the product is abnormal according to the situation, and needs to go to the after-sale maintenance point for maintenance. Specifically, the first performance value may be a performance value recorded after the mobile terminal is shipped, the performance value is first started to operate for a period of time, an average performance value in the period of time is used as an optimal performance value, and the optimal performance value is multiplied by a coefficient value smaller than 1 to be used as the first performance value, wherein the coefficient value is, for example, one third, that is, for example, one third of the performance value at the time of shipment is set as the first performance value to be used as a reference value for determining whether the performance fluctuates.

Specifically, monitoring and alarming performance abnormality of the memory device in the drive layer needs to be implemented as follows: (N1, N2, X1, X2, E0, referred to below, are values that manufacturers have according to the memory device configuration).

Recording the performance value for a period of time after the factory first start-up operation, herein denoted as S0; the method comprises the steps of realizing a read-write time sliding window with the read-write time being N1, counting the average performance of all the read-write times in the read-write time sliding window as the read-write times slide forwards, wherein the average performance of all the read-write times in the read-write time sliding window is S1 (counting the read-write data amount which exceeds the sliding window and is subtracted from the old read-write data amount), and sending warning information to an upper management system if S1 is lower than (S0X 1) and is not recovered within time T1, wherein X1 is a value configured by a manufacturer according to a storage device, and the value is smaller than 1.

The process realizes the discovery and the report of the abnormity of the storage device in the I/O system by continuously obtaining and judging the average performance of the read-write operation in the read-write frequency sliding window.

Correspondingly, on the other hand, as a preferred embodiment, the step of performing, based on the target read-write operation, an exception information feedback when the I/O system has an exception includes:

acquiring the read-write performance corresponding to each read-write operation in the target read-write operation; determining the number of read-write operations of which the read-write performance is lower than a second performance value in the target read-write operations selected from the read-write frequency sliding window according to the read-write performance; if the read-write frequency sliding window continuously slides for N times along with the read-write frequency, and the number is continuously larger than a set number value in the N times of sliding, determining that the storage device in the I/O system is abnormal; and reporting the information that the storage device has abnormity.

Preferably, each time a new read/write operation occurs in the memory device, an obtaining operation of the read/write performance corresponding to each read/write operation in the target read/write operation is performed.

In the process, once per sliding of the read-write frequency sliding window, the selected target read-write operation changes, wherein the latest read-write operation is added, the read-write operation with the longest occurrence time in the original window is discarded, and in the process of performing abnormal information feedback when the I/O system is abnormal according to the target read-write operation selected from the read-write frequency sliding window, the read-write performance corresponding to each read-write operation in the target read-write operation needs to be acquired with each sliding of the read-write frequency sliding window, specifically, the acquisition of the read-write performance can be the calculation of the read-write speed of the read-write operation, the calculation of the read-write operation response time, the calculation of the read-write operation delay, and the like, so as to realize the evaluation and acquisition of the read-write operation performance.

And determining the number of the read-write operations with the read-write performance lower than the second performance value in the target read-write operation based on the read-write performance corresponding to each read-write operation in the target read-write operation, if the number of the read-write operations with the read-write performance lower than the second performance value is continuously greater than a set number value along with the sliding of the read-write frequency sliding window, determining that the memory device in the I/O system is abnormal, and specifically reporting an abnormal message to an upper management system to solve the related problems and realize the rapid positioning and solving of the I/O system abnormality.

Specifically, the second performance value may be a performance value recorded after the mobile terminal is shipped, the performance value is first started to operate for a period of time, an average performance value in the period of time is used as an optimal performance value, and the optimal performance value is multiplied by a coefficient value smaller than 1 to be used as the second performance value, wherein the coefficient value is, for example, one third, that is, for example, one third of the performance value at the time of shipment is set as the second performance value to be used as a reference value for determining whether the performance fluctuates.

The process specifically comprises the following steps: in the read-write operation in the memory device, during each read-write operation, if the performance of the read-write operation is lower than S3 (the factory performance is S1X 2, and X2 is a value configured by a manufacturer according to the device, specifically smaller than 1), a single abnormality is recorded, the number of abnormalities in the read-write frequency sliding window can be counted as E1, along with the sliding of the read-write frequency sliding window, if the number of abnormalities exceeds the range of the sliding window, the abnormality is discarded, and if the read-write operation is continued to be performed N2, the number of abnormalities in the read-write frequency sliding window, E1, is always larger than a set value, namely a threshold value, E0, warning information is sent to an upper.

In the process, because performance fluctuation of short-time read-write operation occurs due to internal processing needs of the device occasionally, the performance fluctuation is normal, so that in the process that the read-write frequency sliding window continuously slides for N times along with the read-write frequency, N is preferably greater than the set read-write frequency of the read-write frequency sliding window, a continuous statistical judgment process is realized, and the accuracy of a judgment result is realized.

The process realizes the discovery and the report of the abnormity of the storage device in the I/O system by continuously counting and judging the number of the read-write operations with lower read-write performance in the read-write frequency sliding window.

As a preferred embodiment, the step of obtaining the read-write performance corresponding to each read-write operation in the target read-write operation in the above process includes:

counting the read-write data volume and the corresponding consumed time of each read-write operation in the target read-write operation; and obtaining the read-write performance according to the read-write data volume and the corresponding consumed time.

By counting the read-write data volume and the corresponding consumed time of each read-write operation, the read-write performance of the corresponding read-write operation can be obtained according to the ratio of the read-write data volume and the corresponding consumed time, and the read-write performance of the read-write operation in the storage device can be obtained.

Specifically, with reference to fig. 3, 4, and 5, several cases of implementing monitoring of read and write operations in a memory device in a driving layer are described as follows:

(1) normal conditions. In a normal situation, as shown in fig. 3, the read-write frequency sliding window slides forward, the read-write performance is basically stable, and no obvious abnormality exists.

(2) Occasional abnormal situations. For the case of the accidental read/write performance abnormality, as shown in fig. 4, the sliding window slides forward along with the read/write times, and an individual performance abnormality point occurs occasionally due to the internal processing requirement of the device, but the performance abnormality point is not frequent and can be recovered to normal, and at this time, the abnormal situation is not considered as a true abnormal situation.

(3) An abnormal situation. For the case that the read-write performance is actually abnormal, as shown in fig. 5, as the read-write frequency sliding window slides forward, the memory device frequently has read-write performance abnormal points, the abnormal frequency in the sliding window in the specified range is greater than the allowable range and cannot be recovered to be normal, and at this time, it is considered that the abnormality occurs, and information is actively sent to the upper management system to alarm.

In each implementation process, monitoring and message alarming are implemented mainly from two key levels of a file system and a storage driver of an I/O system, and the performance condition of the file system is monitored, so that irrelevant processes of background running stealing can be cleared in time, precious I/O bandwidth is released, and system performance and fluency are optimized; by monitoring the performance abnormity of the memory device in the driving layer and actively alarming when the abnormity occurs, users and manufacturers can find out the quality problem of the device in time, and unnecessary loss can be recovered as early as possible. According to the process, the read-write operation of the key module in the I/O system is monitored, warning is given or a user selects and processes the read-write operation when the read-write operation is abnormal, the intelligence degree and the use experience of the system can be improved, the development personnel can be helped to quickly locate the problems related to the I/O system, and further the processing and optimization can be carried out according to specific problems.
