FIG. 2 is a flow diagram of a CPU monitoring method in one embodiment. As shown in fig. 2, a CPU monitoring method includes steps 202 to 206. Wherein:
When the mobile terminal is running, both the system program and the third-party program in the mobile terminal consume CPU (Central Processing Unit) resources in the mobile terminal. The mobile terminal system CPU occupancy rate is the CPU resource occupied by all programs running in the mobile terminal, including the system running program and the third party running program. Generally, the higher the CPU occupancy of the system, the more programs are run in the mobile terminal; the lower the system CPU occupancy, the fewer programs running within the mobile terminal. The mobile terminal can acquire the system CPU occupancy rate according to a preset first time interval, wherein the preset first time interval can be a time interval set by a user or a time interval obtained according to historical acquisition time.
The step of the mobile terminal acquiring the system CPU occupancy may include: the mobile terminal acquires the system CPU accumulated working time length according to a preset first time interval, acquires the difference value between the next CPU accumulated working time length and the previous CPU accumulated working time length in the CPU accumulated working time lengths acquired twice continuously, the difference value is the real working time of the system CPU in the preset first time interval, and the ratio of the difference value to the preset first time interval is the system CPU occupancy rate in the preset first time interval. The accumulated working time of the CPU is the total working time of the CPU from the self-starting of the mobile terminal to the current moment. The preset first time interval may be any time length from 5 seconds to 20 seconds, and preferably may be 5 seconds. For example, the mobile terminal collects the system CPU cumulative operating time every 5 seconds, and if the CPU cumulative operating times collected twice consecutively are 60 minutes 03 seconds and 60 minutes 04 seconds, respectively, the system CPU occupancy rate in the 5 seconds is 20%.
In the Android system, the relevant information of the system CPU can be read under a/proc directory. The stat file under the/proc directory contains all information of system CPU activities, and all the information of the system CPU activities are the time length accumulated by the CPU activities from the self-starting of the mobile terminal to the current moment. The CPU monitoring module in the mobile terminal can read the activity information of the system CPU in the proc directory at regular time and then acquire the system CPU occupancy rate of the mobile terminal in the acquisition time.
And 204, if the difference value between the current system CPU occupancy rate and the last adjacent system CPU occupancy rate exceeds a specified value, taking the current system CPU occupancy rate as the first CPU occupancy rate.
After the mobile terminal obtains the current system CPU occupancy rate, the current system CPU occupancy rate is differed from the last system CPU occupancy rate, and a system CPU occupancy rate difference value is obtained. If the occupancy rate difference value of the system CPU exceeds a specified value, the occupancy rate change of the system CPU of the mobile terminal is judged to be large, and the occupancy rate of the system CPU in the mobile terminal is abnormal. In general, the above-specified value is a positive number, and may be any of 15% to 20%, preferably 20%. The system CPU occupancy rate difference is larger than the specified value, namely the mobile terminal system CPU occupancy rate is suddenly increased, and the mobile terminal system CPU occupancy rate is abnormal. And taking the acquired current system CPU occupancy rate as a first CPU occupancy rate, namely an abnormal CPU occupancy rate.
And step 206, if the system CPU occupancy is not less than the duration of the first CPU occupancy and exceeds the specified duration, acquiring the CPU occupancy of each application program.
And after the mobile terminal acquires the first CPU occupancy rate, acquiring the system CPU occupancy rate in the mobile terminal for the preset times again according to the preset first time interval, and sequentially comparing the acquired system CPU occupancy rate with the first CPU occupancy rate. If the acquired system CPU occupancy rates are not less than the first CPU occupancy rate, the duration of the system CPU occupancy rates which are not less than the abnormal CPU occupancy rates exceeds the specified duration, namely, the application programs in the mobile terminal continuously consume a large amount of CPU resources, and the CPU occupancy rates of the application programs in the mobile terminal are acquired. The preset first time interval may be any time from 5 seconds to 30 seconds, and preferably may be 5 seconds. For example, the system CPU occupancy rates of two consecutive acquisitions by the mobile terminal are 20% and 40%, and the system CPU occupancy rate difference is greater than the specified value of 15%, then the system CPU occupancy rate is 40%, which is taken as the first CPU occupancy rate. The method comprises the steps of collecting the system CPU occupancy rates once every 5 seconds according to a preset first time interval, collecting 4 system CPU occupancy rates which are respectively 42%, 45%, 47% and 50%, wherein the 4 system CPU occupancy rates all exceed 40%, namely the duration of the mobile terminal system CPU occupancy rate exceeding 40% reaches 20 seconds and exceeds a specified duration 18 seconds, and obtaining the CPU occupancy rates of all application programs in the mobile terminal.
The step of the mobile terminal acquiring the CPU occupancy rate of each application program may include: acquiring the accumulated time length occupied by the CPU of each running application program in the mobile terminal according to a preset second time interval, and acquiring the difference value between the accumulated time length occupied by the CPU of the next time and the accumulated time length occupied by the CPU of the previous time in the accumulated time lengths occupied by the CPU of the application programs acquired continuously twice, wherein the difference value is the time that the application program occupies the CPU in the second time interval, and the ratio of the difference value to the second time interval is the CPU occupancy rate of the application program in the second time interval. The first time interval and the second time interval may be the same value or different values.
In the Android system, sats files under a/proc/pid directory contain information that a process corresponding to an application program occupies a CPU. And the information that the process corresponding to the application program occupies the CPU is the accumulated time length that the application program occupies the CPU after being automatically started. The CPU monitoring module in the mobile terminal can read the accumulated time length of the CPU occupied by each application program under the proc/pid directory at regular time and then acquire the CPU occupancy rate of the application program in the acquisition time.
The CPU monitoring method in the embodiment of the invention collects the system CPU occupancy rate, namely the total CPU occupancy rate in the mobile terminal according to the preset first time interval, when the system CPU occupancy rate is detected to be greatly increased and lasts for a long time, the CPU occupancy rate can judge that a large amount of CPU resources are consumed by application programs in the mobile terminal, and the CPU occupancy rate of the application program corresponding to the currently running application program in the mobile terminal is obtained. According to the method, when the total CPU of the system is rapidly increased, the CPU occupancy rate corresponding to the application program can be acquired in time, the CPU occupancy rate of the application program can be monitored, and the abnormal application program can be identified.
In one embodiment, before obtaining the CPU occupancy of each application, the CPU monitoring method further includes:
And 304, if the time difference between the current time and the time for acquiring the CPU occupancy rate of each application program at the last time exceeds a first threshold value, acquiring the CPU occupancy rate of each application program.
Before acquiring the CPU occupancy rates of the application programs corresponding to the application programs, the mobile terminal searches the time of acquiring the CPU occupancy rates of the application programs last time, and acquires the time difference between the current time and the time of acquiring the CPU occupancy rates of the application programs last time. And if the time difference exceeds a preset first threshold, acquiring the CPU occupancy rate of the application program. The step of obtaining the CPU occupancy rate of the application program is the same as the step of obtaining the CPU occupancy rate of the application program in step 206, and is not described herein again. And if the time difference does not exceed a preset first threshold, directly acquiring the CPU occupancy rate of each application program acquired last time as the CPU occupancy rate of each current application program. The first threshold may be a value set by a user, or may be a value obtained by analyzing CPU occupancy data of each application program collected historically, such as 30 seconds, 1 minute, and the like.
The CPU occupancy rate of the application program in the mobile terminal can not change in a short time, and certain system resources are consumed for obtaining the CPU occupancy rate of each application program. In the CPU monitoring method in the embodiment of the invention, after receiving the request for acquiring the CPU occupancy rates of the application programs corresponding to the application programs, the time difference between the current time and the last time of acquiring the CPU occupancy rates of the application programs corresponding to the application programs is firstly acquired, the relation between the time difference and the preset time length is judged, when the time difference is shorter, the CPU occupancy rates of the application programs acquired last time are directly used as the CPU occupancy rates of the current application programs, and when the time difference is longer, the CPU occupancy rates of the application programs are acquired again. The method and the device not only ensure the accuracy of obtaining the CPU occupancy rate of each application program, but also reduce the system power consumption and save the system resources.
In one embodiment, the step 202 of obtaining the system CPU occupancy comprises:
(1) and acquiring a difference value of the accumulated working time of the system CPU acquired for two times as a first difference value.
(2) And acquiring the occupancy rate of the system CPU according to the first difference value and the time interval.
In the Android system, the relevant information of the system CPU can be read under a/proc directory. The stat file under the/proc directory contains all information of system CPU activities, and all the information of the system CPU activities are the time length accumulated by the CPU activities from the self-starting of the mobile terminal to the current moment. The CPU monitoring module in the mobile terminal can read the activity information of the system CPU in the proc directory at regular time and then acquire the system CPU occupancy rate of the mobile terminal in the acquisition time. The step of the mobile terminal acquiring the system CPU occupancy may include: the mobile terminal acquires the system CPU accumulated working time length according to a preset first time interval, acquires the difference value between the next CPU accumulated working time length and the previous CPU accumulated working time length in the CPU accumulated working time lengths acquired twice continuously, the difference value is the real working time of the system CPU in the preset first time interval, and the ratio of the difference value to the preset first time interval is the system CPU occupancy rate in the preset first time interval. The accumulated working time of the CPU is the total working time of the CPU from the self-starting of the mobile terminal to the current moment. The preset first time interval may be any time length from 5 seconds to 20 seconds, and preferably may be 5 seconds.
In one embodiment, the CPU monitoring method further includes:
And step 404, if not, stopping running the process corresponding to the application program.
After the mobile terminal acquires the CPU occupancy rates corresponding to the application programs, sequentially comparing whether the CPU occupancy rates corresponding to the application programs exceed a preset second threshold value, if so, indicating that the CPU occupancy rates of the application programs are too high, and further detecting whether the application programs meet a preset rule. The second threshold may be a value set by a user, or a value obtained by analyzing the CPU occupancy rate of the application program acquired according to history, and the second threshold may be 20%. The preset rules include: the application programs in the system white list, the application programs running in the foreground, the preset actions (including file downloading, file uploading, application program updating and the like) being executed by the application programs, the application programs with higher priority, the application programs for playing music and the like. The preset rule may be a rule set by a user. And when the application program meets the preset rule, the application program is not processed, for example, the application program in a white list set by the user is not processed, and the application program with the first three priorities set by the user is not processed. And when the application program does not meet the preset rule, stopping running the process corresponding to the application program. Wherein, stopping running the process corresponding to the application program comprises: closing or suspending the process corresponding to the application program, wherein closing the process corresponding to the application program refers to terminating (kill) the process corresponding to the application program, suspending the process corresponding to the application program refers to suspending the operation of the process corresponding to the application program, the process corresponding to the suspended application program can be added into a waiting queue, and when the system CPU occupancy rate is low, the operation of the process corresponding to the application program is resumed.
The CPU monitoring method in the embodiment of the invention detects whether the application program is a non-processing application program preset by the mobile terminal or a non-processing application program set by a user when the CPU occupancy rate of the application program in the mobile terminal is high. When the application program is not processed, the corresponding operation of the application program is stopped, namely, the application program with the abnormal CPU occupancy rate is subjected to killing processing, so that the phenomenon that the abnormal application program in the mobile terminal consumes a large amount of CPU resources to cause the system of the mobile terminal to be blocked, generate heat and the like is avoided. The preset rules can ensure that the application program is not cleaned under the condition that the application program normally occupies a large amount of CPU resources, so that the accuracy of identifying the abnormal application program is improved, and the abnormal application program is checked and killed more accurately.
In one embodiment, the CPU monitoring method further includes:
and 502, acquiring a corresponding CPU occupancy level according to the system CPU occupancy rate.
Multiple CPU occupancy levels may be pre-divided, and each occupancy level may correspond to a different occupancy range, for example, 4 CPU occupancy levels are divided, including L1, L2, L3 and L4, where the occupancy range corresponding to the L1 occupancy level is less than 20%, the occupancy range corresponding to the L2 occupancy level is 20% -40%, the occupancy range corresponding to the L3 occupancy level is 40% -60%, the occupancy range corresponding to the L4 occupancy level is greater than 60%, and the like, without being limited thereto. The mobile terminal collects the system CPU occupancy rate according to a preset first time interval, can determine the occupancy rate range in which the collected system CPU occupancy rate falls, and obtains the CPU occupancy level corresponding to the falling occupancy rate range. For example, if the collected system CPU occupancy is 18%, the CPU occupancy level is L1, and if the system CPU occupancy is 25%, the CPU occupancy level is L2.
At step 504, the number of times the occupancy level is continuously maintained is accumulated.
The mobile terminal may assign a level counter to each CPU occupancy level, and record the consecutive times of the CPU being maintained at the corresponding occupancy level through the level counter, where the CPU being maintained at a certain occupancy level means that the CPU is always at the occupancy level or above, for example, if the CPU occupancy level is changed to L2 occupancy level, L3 occupancy level, or L2 occupancy level, the CPU may be considered to be maintained at L2 occupancy level, and the consecutive times are 3.
In one embodiment, the mobile terminal acquires the system CPU occupancy rate according to a preset first time interval, determines the CPU occupancy level, and may add 1 to level counters corresponding to the occupancy level and below the occupancy level, and clear the level counters of other occupancy levels. For example, if the current CPU occupancy level is L3, the level counters of L1, L2, and L3 are incremented by 1, and the level counter of L4 is cleared, and if the next CPU occupancy level is L2, the level counters of L1 and L2 are incremented by 1, and the level counters of L3 and L4 are cleared.
In one embodiment, the types of the occupancy levels may be divided, wherein the types may include an idle level and a busy level, for example, the L1 occupancy level is used as the idle level, and the L2, L3 and L4 occupancy levels are used as the busy levels, which respectively represent different busy levels. The mobile terminal collects the occupancy rate of the CPU of the system at intervals of a preset first time interval, calculates the occupancy level of the CPU, can determine the corresponding type firstly, then adds 1 to the level counters corresponding to the occupancy levels of the same type and below the occupancy level respectively, and clears the level counters of other occupancy levels. For example, if the current CPU occupancy level is L1 and belongs to the idle level, the level counter of L1 is incremented by 1, the level counters of L2, L3, and L4 are cleared, and if the next CPU occupancy level is L3 and belongs to the busy level, the level counters of L3 and L2 that belong to the busy level are incremented by 1, and the level counters of L1, and L4 are cleared, respectively.
A corresponding third threshold may be set for each CPU occupancy level, and the third threshold may be used to determine whether the CPU of the mobile terminal is maintained in the operating state of the corresponding occupancy level. The mobile terminal accumulates the number of times that the CPU is continuously maintained at each occupation level through the level counter, and when the number of times that the CPU is continuously maintained at the occupation level reaches a third threshold value corresponding to the occupation level, the mobile terminal can determine that the CPU is stable in the working state of the occupation level. For example, a corresponding third threshold value of c1, c2, c3 and c4 is set for each of L1, L2, L3 and L4, and when the number of times that the CPU continuously maintains the level of L1 reaches c1, the CPU is determined to be stable in the operating state of L1. Further, the third threshold corresponding to each occupancy level may decrease with the increase of the occupancy level, for example, the third thresholds corresponding to L1, L2, L3 and L4 are c1, c2, c3 and c4, where c1> c2> c3> c4, for example, c1 is 5 times, c2 is 4 times, c3 is 3 times, c4 is 2 times, etc., but not limited thereto. In one embodiment, if there are multiple occupation levels with the number of continuous maintenance times reaching the corresponding third threshold, the occupation level with the highest level is selected as the stable operating state of the CPU.
The CPU monitoring method in the embodiment of the invention sets different occupancy levels for the CPU occupancy rate, determines the busy degree of the mobile terminal according to the times of maintaining the occupancy levels, is beneficial to carrying out different processing on the application program according to the busy program of the mobile terminal, and directly closes the process corresponding to the abnormal application program if the occupancy level is higher and the system is busy; when the occupation level is low and the system is idle, the process corresponding to the abnormal application program is suspended, and the flexibility of processing the abnormal application program is improved.
In an embodiment, before stopping running the process corresponding to the application program, the CPU monitoring method further includes:
step 602, displaying abnormal information corresponding to the application program and a stop operation instruction for the application program on the interface of the mobile terminal.
In step 604, if a trigger operation for the stop operation instruction is received, the process corresponding to the application program is stopped to operate.
Before stopping running the process corresponding to the application program, the mobile terminal can also display abnormal information corresponding to the application program on a mobile terminal interface. The above-mentioned abnormality information may include: the current CPU occupancy rate of the application program, the current program behavior of the application program (such as background downloading files and the like), the current network speed occupied by the application program and the like. In addition to showing the application's instructions to stop running, a cancel instruction may also be shown. If the trigger operation for the cancel instruction is acquired, the application program is not processed; and if the trigger operation of the operation stopping instruction is obtained, stopping operating the process corresponding to the application program.
According to the CPU monitoring method in the embodiment of the invention, after the abnormal application program is detected, the abnormal information corresponding to the application program is displayed on the interface of the mobile terminal, and the process corresponding to the application program is stopped after the operation stopping instruction of the user is received, so that the misoperation of checking and killing the application program can be avoided, and the precision of checking and killing the application program is improved.
