Detailed Description
The present application will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application. It should be further noted that, for the convenience of description, only some of the structures associated with the present application are shown in the drawings, not all of them.
Example one
Fig. 1 is a schematic flowchart of a fault location method for BMC abnormal restart according to an embodiment of the present application, which is applicable to a fault location scenario for BMC abnormal restart. The method can be executed by a fault positioning device for abnormal restart of the BMC, the device can be realized in a hardware and/or software mode, and can be generally integrated in electronic equipment such as a computer with data operation capability, and the method specifically comprises the following steps:
Because the BMC system may periodically execute the dog feeding operation when the BMC system normally operates, and the dog feeding operation is usually to send a dog feeding instruction to the watchdog system, this embodiment may monitor whether the BMC system sends the dog feeding instruction, and if it is monitored that the dog feeding instruction is sent, it is determined that the BMC system is executing the dog feeding operation.
Specifically, the method can be implemented by detecting all information sent by the BMC system to the watchdog system, and when the BMC system sends out the information that the sending target is the watchdog system, the information is analyzed, whether a dog feeding instruction is included in an analysis result is judged, and if the dog feeding instruction is included, it can be judged that the dog feeding instruction is sent out.
By the means, when the BMC system is detected to execute the dog feeding operation, the timestamp at the moment can be obtained, namely the timestamp when the BMC system is detected to execute the dog feeding operation is obtained. It should be noted that the format of the time stamp may be "year/month/day/hour/minute/second/millisecond", and in a specific example, the time stamp may be "2022/10/11/08/24/35/65".
And 102, determining a preset storage position, and storing the acquired time stamp in the preset storage position.
In this step, the preset storage location is located in a memory space partitioned from a reserved memory of the BMC system in advance, and in order to implement independent storage of the timestamps before and after restarting and avoid the timestamp after restarting, the condition that the timestamp before restarting is lost due to the fact that the offset pointer used for caching after restarting is reset and stored in the storage location of the timestamp before restarting is covered can be set as a double-cache structure.
Specifically, a first buffer area and a second buffer area are set in the memory space, corresponding preset values are set for the first buffer area and the second buffer area respectively, and then a preset buffer identification bit is set for storing the preset values. And judging the current position for storing the timestamp by identifying the value of the preset cache identification bit, and changing the current position for storing the timestamp by modifying the value of the preset cache identification bit.
Based on the preset setting, when the preset storage position is determined in the step, the value of the preset cache identification bit can be obtained first, and if the value of the preset cache identification bit is a first preset value, a first cache region in a memory space which is applied in advance is set as the preset storage position; and if the value of the preset cache identification bit is a second preset value, setting a second cache region in the memory space which is applied in advance as a preset storage position.
In a specific example, the first preset value may be "0", the second preset value may be "1", the identifier of the first buffer is the first preset value, and the identifier of the second buffer is the second preset value. When the preset storage position is determined, firstly, a value in the preset cache identification bit is obtained, then, whether the value is '1' or '0' is judged, if the value is '1', namely a second preset value, the preset storage position is a second cache region, and if the value is '0', namely a first preset value, the preset storage position is a first cache region.
It should be noted that before the preset storage location is determined, it is determined whether the timestamp is currently stored for the first time, and if the timestamp is stored for the first time, the first buffer area, the second buffer area and the offset pointers corresponding to the first buffer area and the second buffer area in the pre-applied memory space are emptied, and the value of the preset buffer identification bit is initialized.
Specifically, the log record may be performed for each storage operation, before the preset storage location is determined each time, it may be determined whether the current storage is the first storage according to the log record, and if there is a related log record, the current storage is not the first storage, and at this time, the step of determining the preset storage location may be directly performed.
If no related log record exists, the first buffer area, the second buffer area, the corresponding offset pointer and the preset buffer identification bit are initialized to the first preset value or the second preset value for the first storage. And then the step of determining the preset storage position is performed.
In this step, after the preset storage location is determined, the acquired timestamp may be stored in the preset storage location. It should be noted that, because each cache region has a plurality of storage bits, determining a specific storage bit may be obtained by using an offset pointer, and the storage process may refer to a related technology of storing data in the cache region by using an offset pointer, which is not described herein again.
Further, after the abnormal restart of the BMC system, the value of the preset cache identification bit is updated. Usually, the first preset value is updated to the second preset value or the second preset value is updated to the first preset value.
Based on the updating operation, when the timestamps are stored before and after restarting, the determined preset storage positions are respectively the first cache region and the second cache region. For example, the preset storage location determined before the restart is a first cache region, the value of the preset cache identification bit is updated after the restart, the first preset value is updated to be a second preset value, and the preset storage location determined after the restart is a second cache region, so that the preset storage locations determined before and after the restart are different.
The specific updating process may be that, after the BMC system is abnormally restarted each time, the value of the current preset cache identification bit is determined; if the value of the current preset cache identification bit is a first preset value, updating the value of the preset cache identification bit to a second preset value; and if the current value of the preset cache identification bit is the second preset value, updating the value of the preset cache identification bit to the first preset value.
In a specific example, after the abnormal restart, the value of the current preset cache identification bit is determined to be "1", which indicates that the preset storage location determined before the restart is the second cache region, at this time, "1" is updated to "0", and the preset storage location determined thereafter is the first cache region.
It should be noted that the updated occurrence time may be any time occurring in the time period after the restart and before the first execution of the dog feeding operation after the restart.
In order to avoid data loss in the cache region after power failure, in this embodiment, after the BMC system is abnormally restarted each time, a file in a pre-created file directory may be transferred to the nonvolatile memory. Because the nonvolatile memory cannot be influenced by power failure, namely the data stored after power failure cannot be lost, after the operation, the stored timestamp cannot be lost or damaged due to power failure of the system, and subsequent fault location based on the timestamp can be carried out at any time, so that convenience is provided for later comprehensive analysis.
It should be noted that the files in the pre-created file directory are obtained after a read operation. Since the present embodiment stores the timestamp in a double-cache-area manner, during reading, the read position needs to be determined according to the value in the preset cache identification bit.
Specifically, under the condition that a timestamp reading request is received, the current value of a preset cache identification bit is obtained; if the current value of the preset cache identification bit is a first preset value, reading a timestamp from a first cache region in a pre-applied memory space; if the current value of the preset cache identification bit is a second preset value, reading a timestamp from a second cache region in a pre-applied memory space; the read time stamp is stored in a file form in a file directory created in advance.
The timestamp reading request can be generated and sent periodically, so that the timestamp in the cache region can be read into the file, and the reliability of timestamp storage is improved by matching with the unloading operation (namely unloading the file into the nonvolatile memory).
In addition, in order to avoid repeated reading of the time stamp in the buffer, each time reading is performed, a specific position of the read buffer may be recorded, and the next reading may be started from a next storage address of the specific position.
Specifically, after the timestamp is read, the value of the preset cache identification bit corresponding to the read cache region and the read address at the tail end are recorded, when reading is performed next time, whether the value of the preset cache identification bit is consistent with the value recorded at the previous time or not is judged first, if so, reading is started from the next address of the read address at the tail end, and if not, all timestamps are read from the corresponding cache region.
Further, the timestamp reading request may also be sent by the user layer, and the user may generate and send the timestamp reading request in the user layer according to the requirement, and then read the corresponding file from the file directory to obtain the read timestamp.
It should be noted that, in addition to the time stamp, the content stored in the file may further include a reading location (for example, the first buffer or the second buffer) and the number of time stamps stored before the reading location changes, that is, the number of time stamps stored by the device before each system restart and after the previous system restart.
In this step, when the fault occurrence time period is determined, the latest timestamp before restart may be used as the start time of the fault occurrence time period, the current time may be used as the end time of the fault occurrence time period, and the start time and the end time constitute the fault occurrence time period.
Further, sometimes, after the fault occurs, a period of time is accumulated to result in that the dog feeding operation cannot be performed, and the determined fault occurrence period may not include the time when the fault occurs. Therefore, the present embodiment may preset a tolerant time, and then advance the start time by the tolerant time to obtain a new start time, and use the new start time and the new end time to form the fault occurrence time period.
In a specific example, the allowance time may be 20 seconds, the latest timestamp corresponds to 30 minutes and 25 seconds at 31/10/2022, and 30 minutes and 5 seconds at 8/31/10/2022 after the allowance time is advanced, the new start time is 20 seconds at 5/30 minutes at 31/10/2022.
After the fault occurrence time period is determined, the log information of the BMC system in the fault occurrence time period can be obtained. It should be noted that each log has a corresponding log time, and the logs corresponding to all the log times belonging to the fault occurrence time period may be screened, so as to obtain the log information in the fault occurrence time period.
And step 104, positioning the abnormal restarting fault of the BMC system according to the log information in the fault occurrence time period.
In this step, fault location is performed according to the log information, and it should be noted that the specific process of location may refer to related technologies, which are not described herein again.
According to the technical scheme, the dog feeding operation of the BMC system is monitored in real time, the current timestamp is acquired under the condition that the BMC system performs the dog feeding operation each time, then the preset storage position is determined, and the acquired timestamp is stored in the preset storage position. After the abnormal restarting of the BMC system every time, a timestamp stored between restarting is obtained, a fault occurrence time period is determined based on the timestamp before restarting, then log information of the BMC system in the fault occurrence time period is obtained, and finally the fault of the abnormal restarting of the BMC system is located according to the log information. Based on this, when the BMC system normally operates, the dog feeding operation can be executed regularly, but the dog feeding operation can be stopped after the fault occurs, at this moment, a timestamp capable of being stored does not occur, then after the restart, a time period in which the fault occurs can be determined according to the timestamp stored before the restart, and then the fault of the abnormal restart can be more accurately and comprehensively positioned according to log information recorded by the time period system.

And step 203, acquiring the current time stamp under the condition that the BMC system performs the dog feeding operation each time.
And step 206, if the value of the preset cache identification bit is a second preset value, setting a second cache region in the memory space applied in advance as a preset storage position.
And step 207, storing the acquired time stamp in a preset storage position.
And step 208, after the abnormal restart of the BMC system every time, determining whether the value of the current preset cache identification bit is a first preset value.

And step 213, acquiring the log information of the BMC system in the fault occurrence time period.
And 214, positioning the abnormal restarting fault of the BMC system according to the log information in the fault occurrence time period.
According to the scheme of the embodiment, when the BMC system normally runs, the dog feeding operation can be executed regularly, but the dog feeding operation can be stopped after a fault occurs, a timestamp which can be stored cannot occur at the moment, after the system is restarted, the time period of the fault occurrence can be determined according to the timestamp stored before the system is restarted, and then the abnormal restarting fault can be more accurately and comprehensively positioned according to log information recorded by the time period system.
