The abnormal mark corresponding to the character string resource is preset and is used for representing the abnormal mark of the character string resource. It should be noted that the abnormal identifiers of the character string resources corresponding to different key information points are different. The setting rule of the abnormal identifier of the character string resource can be set according to specific requirements, and the character string resource corresponding to different key information points can be identified as long as the character string resource can be identified.
Further, referring to fig. 4, step S101 includes:
in step S1011, after a monitoring instruction for monitoring a preset key information point in the Kernel layer system service module of the mobile terminal is detected, the state value of the key information point is read according to the monitoring instruction.
Step S1012, determining whether the string resource at the corresponding position of the key information point is abnormal according to the state value.
Step S1013, if the string resource is abnormal, the abnormal identifier corresponding to the string resource is read.
After the mobile terminal detects a monitoring instruction for monitoring a preset key information point in a Kernel layer system service module of the mobile terminal, reading a state value of the preset key information point according to the monitoring instruction, and determining whether a character string resource at a position corresponding to the preset key information point is abnormal or not according to the state value. And if the character string resource at the corresponding position of the key information point is determined to be abnormal according to the state value, the mobile terminal reads the abnormal identification corresponding to the character string resource. If the character string resource of the corresponding position of the key information point is determined not to be abnormal according to the state value, the character string resource is indicated to have no corresponding abnormal identifier, and the mobile terminal cannot read the abnormal identifier corresponding to the character string resource.
Wherein, the state value and the abnormal state are in corresponding relation. In this embodiment, the corresponding relationship between the state value and the abnormal state may be limited according to specific needs, and is not limited herein. If the state value corresponding to a certain key information point is set to be 0, determining that the character string resource at the corresponding position of the key information point is not abnormal; and when the state value corresponding to a certain key information point is 1, determining that the character string resource at the corresponding position of the key information point is abnormal.
And step S102, matching the abnormal identification with a pre-stored log identification.
Step S103, if the abnormal identifier is successfully matched with the log identifier, the log information associated with the log identifier is searched according to the log identifier, and the process information of the process corresponding to the character string resource is obtained.
And after the abnormal identification corresponding to the character string resource is obtained, the mobile terminal matches the obtained abnormal identification with the log identification stored in the database for storing the restart operation reasons. If the abnormal identifier is successfully matched with the log identifier, the mobile terminal searches the log information associated with the log identifier in a database storing the restart operation reason according to the log identifier and acquires the process information of the process corresponding to the character string resource. Note that the log identifier is an identifier corresponding to log information that causes the restart operation of the mobile terminal. The log information includes, but is not limited to, a node name where the string resource abnormality occurs in the system service module and a location where the string resource abnormality occurs in the system service module. The process information includes, but is not limited to, when an exception occurs in a string resource, a name of a corresponding process, that is, a name of a related process, a name of an associated thread, an ID (identification) and a thread ID of an interactive or associated process with the related process, and a function node of a system service module corresponding to the key information point.
In this embodiment, when the abnormal identifier is consistent with the pre-stored log identifier, it is determined that the abnormal identifier is successfully matched with the pre-stored log identifier; and if the abnormal identifier is inconsistent with the pre-stored log identifier, confirming that the abnormal identifier is failed to be matched with the pre-stored log identifier. If the abnormal identifier is a, finding the log identifier which is the identifier a in the database, confirming that the abnormal identifier is successfully matched with the pre-stored log identifier, and otherwise, confirming that the abnormal identifier is unsuccessfully matched with the pre-stored log identifier. In other embodiments, it may be set that when the abnormal identifier is associated with the pre-stored log identifier, it is determined that the abnormal identifier is successfully matched with the pre-stored log identifier, and otherwise, it is determined that the abnormal identifier is unsuccessfully matched with the pre-stored log identifier. If the log identifier set to be associated with the abnormal identifier a1 is a2, if the abnormal identifier corresponding to the character string resource of a certain key information point is a1 and the log identifier identified as a2 is found in the database, it is determined that the abnormal identifier is successfully matched with the pre-stored log identifier, otherwise, it is determined that the abnormal identifier is unsuccessfully matched with the pre-stored log identifier.
And step S104, generating a restart log according to the process information and the log information so as to locate the restart reason of the mobile terminal according to the restart log.
After the process information and the log information are acquired, the mobile terminal generates a restart log according to the process information and the log information and outputs the restart log to a specified position, so that corresponding workers can quickly acquire the restart log after the restart operation of the mobile terminal occurs, and the restart reason causing the restart operation of the mobile terminal is quickly determined according to the restart log.
Further, in the process of generating the restart log according to the process information and the log information, the mobile terminal generates the restart log according to a specific format, so that a corresponding worker can quickly analyze the reason of the restart operation of the mobile terminal according to the restart log.
Further, the system service-based restart location method further includes:
step a, determining whether the position character string resource corresponding to the monitoring key information point is abnormal or not, and deploying the thread in a kthread process and a Kernel process of a Kernel layer.
Furthermore, when the mobile terminal deploys the Kernel layer process, determining a monitoring instruction corresponding thread for monitoring whether the character string resources at the corresponding positions of the preset key points of the Kernel layer system service module are abnormal or not, and deploying the thread corresponding to the monitoring instruction in the kthread process and the Kernel process of the Kernel layer, so that whether the character string resources in the Kernel layer system service module are abnormal or not can be monitored in the whole process. It should be noted that the thread corresponding to the monitoring instruction is independently run in the mobile terminal.
In the embodiment, when the abnormality of the character string resource at the position corresponding to the preset key information point in the mobile terminal Kernel layer system service module is monitored, the abnormal identification corresponding to the character string resource is read; matching the abnormal identifier with a pre-stored log identifier; if the abnormal identification is successfully matched with the log identification, searching log information associated with the log identification according to the log identification, and acquiring process information of a process corresponding to the character string resource; and generating a restart log according to the process information and the log information so as to locate the restart reason of the mobile terminal according to the restart log. The method and the device have the advantages that the restart log corresponding to the restart operation of the mobile terminal is obtained in advance before the restart operation of the mobile terminal does not occur, so that corresponding workers can quickly determine the reason causing the restart of the mobile terminal according to the restart log after the restart operation of the mobile terminal occurs, the efficiency of locating the reason causing the restart fault of the mobile terminal is improved, and the labor cost is reduced.
Further, a second embodiment of the system service based restart location method according to the present invention is proposed based on the first embodiment. The second embodiment of the system service based restart location method differs from the first embodiment of the system service based restart location method in that the step of reading the state value of the key information point according to the monitoring instruction comprises:
and b, reading a preset number of first state values of the key information points according to the monitoring instruction and the first reading frequency.
And c, if the character string resources are determined not to be abnormal according to the first state values of the preset number, reading the second state values of the preset number of the key information points according to the second reading frequency.
And d, if the character string resources are determined not to be abnormal according to the preset number of second state values, reading a third state value of the key information points according to a third reading frequency, wherein the second reading frequency is greater than the first reading frequency and less than the third reading frequency.
The process of the mobile terminal reading the state value of the key information point according to the monitoring instruction is as follows: the mobile terminal reads the first state values of the preset number of the key information points according to the monitoring instruction and the first reading frequency, and judges whether the read first state values of the preset number can determine that the character string resource is not abnormal. If the read first state values of the preset number can determine that the character string resource is not abnormal, reading second state values of the preset number of the key information points according to a second reading frequency, and judging whether the read second state values of the preset number can determine that the character string resource is not abnormal. If the read second state values with the preset number can determine that the character string resources are not abnormal, reading third state values with the preset number of key information points according to a third reading frequency so as to determine whether the character string resources at the corresponding positions of the key information points are abnormal or not according to the third state values.
The second reading frequency is less than the first reading frequency and greater than the third reading frequency. The first reading frequency, the second reading frequency, the third reading frequency and the preset number can be set according to specific needs, for example, the first reading frequency can be set to be read every 1 second, the second reading frequency can be set to be read every 3 seconds, the third reading frequency can be set to be read every 5 seconds, and the preset number can be set to be 5. That is, after the status values read by the mobile terminal at 1 second intervals for 5 consecutive times according to the monitoring instruction indicate that the character string resource is not abnormal, the status values corresponding to the key information points are continuously read for 5 times at 3 seconds intervals, if the status values read for 5 times at 3 seconds intervals indicate that the character string resource is not abnormal, the status values corresponding to the key information points are continuously read for 5 times at 5 seconds intervals, and whether the character string resource at the corresponding position of the key information point is abnormal is determined according to the 5 status values continuously read for 5 seconds at intervals.
It should be noted that, in other embodiments, the reading frequency for reading the state values of the key information points may be further increased, for example, if 5 state values continuously read every 5 seconds indicate that the string resource is not abnormal, the state values corresponding to the key information points are continuously read 5 times every 8 seconds. This is not particularly limited in the present embodiment.
Further, the system service-based restart location method further includes:
and e, if the character string resource is determined to be abnormal according to a first state value, detecting whether the mobile terminal is subjected to restarting operation.
And f, if the mobile terminal is not restarted, reading the state value of the key information point according to a fourth reading frequency.
Further, if it is determined that the character string resource is abnormal according to one first state value in the process of reading the preset number of first state values of the key information points according to the first reading frequency according to the monitoring instruction, the mobile terminal detects whether the restart operation occurs. And if the mobile terminal is not subjected to the restarting operation, the mobile terminal reads the state value of the key information point according to the fourth reading frequency. Further, if the mobile terminal is restarted, it indicates that the mobile terminal has been initialized, and the mobile terminal detects whether a monitoring instruction for monitoring a state value of a preset key information point in a Kernel layer system service module of the mobile terminal is detected. The fourth reading frequency can be set according to specific needs, and if the fourth reading frequency is set to be equal to the first reading frequency, the fourth reading frequency and the first reading frequency are set to be read once every 1 second; or set to be unequal to the first reading frequency, such as setting the fourth reading frequency to be read every 0.8 seconds, or every 2 seconds.
For ease of understanding, the process is illustrated: when the mobile terminal continuously reads the state value of the key information point for 5 times at intervals of 1 second according to the monitoring instruction, if the watchdog at the corresponding position is determined to be abnormal according to the state value of the key information point read at the 3 rd second and the mobile terminal is not restarted, the mobile terminal reads the state value of the key information point once at intervals of 0.8 (at this time, the fourth reading frequency is set to be 0.8 second reading time).
It can be understood that, if the character string resource is determined to be abnormal according to a second state value or a third state value, the mobile terminal detects whether a restart operation occurs.
In this embodiment, by setting the reading frequency for reading the key information points, the reading frequency for reading the state values of the key information points is reduced when the string resources at the corresponding positions of the key information points of the system service module are not abnormal, so that the times for reading the state values of the key information points are reduced when the string resources are not abnormal.
Further, a third embodiment of the system service based restart location method according to the present invention is proposed based on the first embodiment. The third embodiment of the system service based restart location method differs from the first and/or second embodiment of the system service based restart location method in that, referring to fig. 5, the system service based restart location method further includes:
step S105, storing the restart log, and determining the restart log stored in the second preset time.
And step S106, performing redundancy removing operation on the log information stored in the second preset time so as to save storage space.
And after the restart log is generated, the mobile terminal stores the restart log, determines the restart log stored in the second preset time, and executes redundancy removing operation on the restart log stored in the second preset time so as to save the storage space of the mobile terminal. Specifically, in the process of executing redundancy removing operation, only one restart log belonging to the same type of restart operation is stored, other restart logs corresponding to the stored type of restart operation are deleted, the number of the restart logs belonging to the same type of restart operation and whether the corresponding watchdog is converted from the abnormal state to the normal state are correspondingly recorded, and the conversion time of the watchdog from the abnormal state to the normal state is recorded. The second preset time can be set according to specific needs, for example, the second preset time can be set to 45 minutes, 60 minutes, or 100 minutes, etc. It should be noted that, in the process of performing classified storage on the restart log, the restart log may be classified and stored according to the reason of the restart, or may be classified according to the location of the restart, which is not limited herein.
For example, when the mobile terminal has an abnormal phenomenon of a string resource error within 60 minutes from 10 o 'clock to 11 o' clock, a total of 1000 restart logs are stored in the mobile terminal. At this time, the mobile terminal classifies restart logs of restart operations belonging to the same category into one category before the string resource is changed from the abnormal state to the normal state. If 520 restart logs correspond to the A1 restart operations, 360 restart logs correspond to the B1 restart operations, and 120 restart logs correspond to the C1 restart operations, only one restart log corresponding to the A1 restart operations is stored, the restart logs corresponding to the rest 519 restart operations of the A1 are deleted, and the number of the restart logs corresponding to the A1 restart operations is recorded as 520; storing a restart log corresponding to the B1 type restart operation, deleting the rest 359 restart logs corresponding to the B1 type restart operation, and recording the number of the restart logs corresponding to the B1 type restart operation as 360; storing a restart log corresponding to the C1 type restart operation, deleting the rest 119 restart logs corresponding to the C1 type restart operation, and recording the number of the restart logs corresponding to the C1 type restart operation as 120.
It should be noted that the solution of the redundancy elimination operation may also be applicable to process information and log information, and when the redundancy elimination operation is performed on the process information and the log information, the specific operation process is consistent with the redundancy elimination operation process performed on the restart log, which is not described herein again.
In the embodiment, redundancy removal operation is performed on the restart log stored in the second preset time, so that the storage space of the mobile terminal is saved.
Further, the system service-based restart location method further includes:
and g, judging whether the character string resource of the corresponding position of the key information point is monitored again to be abnormal within the first preset time after the process information is acquired.
And h, if the character string resource of the corresponding position of the key information point is monitored to be abnormal again in the first preset time, storing the process information.
Further, after the mobile terminal acquires the process information, the mobile terminal judges whether the character string resource of the corresponding position of the key information point is monitored again to be abnormal within a first preset time after the process information is acquired. If the character string resource of the corresponding position of the key information point is monitored to be abnormal again within the first preset time, the mobile terminal stores the process information so as to generate a restart log according to the process information. Further, if the character string resource of the corresponding position of the key information point is not monitored to be abnormal again within the first preset time, the mobile terminal deletes the acquired process information. The first preset time can be set according to specific needs, for example, the first preset time can be set to 3 minutes, 5 minutes, or 8 minutes.
In this embodiment, the accuracy of locating the restart reason of the mobile terminal is improved by judging whether the abnormality of the character string resource is monitored again within the first preset time.
Further, a fourth embodiment of the system service based restart location method according to the present invention is proposed based on the first embodiment. The fourth embodiment of the system service based reboot positioning method differs from the first and/or second embodiment of the system service based reboot positioning method in that, referring to fig. 6, the system service based reboot positioning method further includes:
and S107, determining an identification node, a loading node, an initialization node, an operation node, an instruction allocation node, a cross-process data communication node, an unloading node, a resource application and release node and a disk read-write operation node of a system service module calling process in the Kernel layer.
And step S108, setting key information points in the identification node, the loading node, the initialization node, the operation node, the instruction allocation node, the cross-process data communication node, the unloading node, the resource application and release node and the disk read-write operation node.
The method can accurately and quickly locate the reason for restarting the system service module in the Kernel layer of the mobile terminal. The mobile terminal determines an identification node, a loading node, an initialization node, a running node, an instruction allocation node, a cross-process data communication node, an unloading node, a resource application and release node and a disk read-write operation node of a system service module calling process in a Kernel layer, and sets key information points in the identification node, the loading node, the initialization node, the running node, the instruction allocation node, the cross-process data communication node, the unloading node, the resource application and release node and the disk read-write operation node so as to monitor whether the character string resources of the corresponding nodes are abnormal or not through the key information points. It can be understood that the identification node, the loading node, the initialization node, the operation node, the instruction deployment node, the cross-process data communication node, the unloading node, the resource application and release node, and the disk read-write operation node are important nodes in the system service module call flow.
Further, in order to quickly locate a restart reason of the restart operation of the mobile terminal, the mobile terminal determines a sequential logic of each function in the system service module, and sets a key information point in each function node corresponding to the sequential logic. For example, the sequential logic of a certain function in the system service module is: a → B → C → D, then set key information points at node A, node B, node C and node D, respectively.
It can be understood that, because the key information points are set in the call flow and the timing logic of the service corresponding to the different modules of the mobile terminal, after the restart operation of the mobile terminal is determined, the type of the restart operation can be determined according to the key information points, that is, it is determined that the restart operation is caused by the abnormality of the Java framework layer, the Native framework layer, or the system service module in the Kernel layer.
In the embodiment, the key information points are set at the identification node, the loading node, the initialization node, the operation node, the instruction allocation node, the cross-process data communication node, the unloading node, the resource application and release node and the disk read-write operation node of the call flow of the system service module, and whether the corresponding character string resource is abnormal or not is judged by monitoring each key information point in the system service module, so that the restart reason of the restart operation of the important node in the call flow of the system service module of the mobile terminal is positioned.

and if the character string resource is abnormal, reading an abnormal identifier corresponding to the character string resource.
Further, the step of reading the state value of the key information point according to the monitoring instruction includes:
reading a preset number of first state values of the key information points according to the monitoring instruction and a first reading frequency;
if the character string resources are determined not to be abnormal according to the first state values of the preset number, reading second state values of the preset number of the key information points according to a second reading frequency;
and if the character string resources are determined not to be abnormal according to the preset number of the second state values, reading a third state value of the key information point according to a third reading frequency, wherein the second reading frequency is smaller than the first reading frequency and larger than the third reading frequency.
Further, after the step of reading the preset number of first state values of the key information points according to the monitoring instruction and the first reading frequency, the system service-based restart location program implements the following steps when being executed by the processor:
if the character string resource is determined to be abnormal according to the first state value, detecting whether the mobile terminal is subjected to restarting operation;
and if the mobile terminal is not subjected to restarting operation, reading the state value of the key information point according to a fourth reading frequency.
Further, before the step of generating a restart log according to the process information and the log information, so as to locate the restart reason of the mobile terminal according to the restart log, the system service-based restart location program implements the following steps when being executed by a processor:
judging whether the character string resource of the corresponding position of the key information point is monitored again to be abnormal within a first preset time after the process information is acquired;
and if the character string resource of the corresponding position of the key information point is monitored to be abnormal again in the first preset time, storing the process information.
Further, after the step of generating a restart log according to the process information and the log information, so as to locate the restart reason of the mobile terminal according to the restart log, the system service-based restart location program implements the following steps when being executed by a processor:
storing the restart log, and determining the restart log stored in a second preset time;
and performing redundancy removing operation on the log information stored in the second preset time so as to save storage space.

and setting key information points in the identification node, the loading node, the initialization node, the operation node, the instruction allocation node, the cross-process data communication node, the unloading node, the resource application and release node and the disk read-write operation node.

and determining a thread for monitoring whether the position character string resource corresponding to the key information point is abnormal or not, and deploying the thread in a kthreadd process and a Kernel process of the Kernel layer.
