As shown in fig. 3, an embodiment of the present invention provides a solid state disk log processing method, which is applied to a solid state disk, and the method includes:
step S301, acquiring a log file generated by a processor, analyzing the log file, and generating log information, wherein the log information comprises time information and log content.
The method and the device have the advantages that the engineer can know the generation time and the log content of the log information when consulting the log information, so that the engineer can solve problems according to the time and the log content of the log in time. When the solid state disk starts to work, a log file generated by the processor is acquired, and after the log file is acquired, the log file is analyzed according to a preset rule so as to generate log information, for example, the log file is analyzed into a piece of log content, and time information is added to the log content according to the time generated by the log content so as to generate the log information. For example, the analyzed log content is: "Power lost Handled on CPU", that is, the CPU is powered down, but since these log contents are not only once but also do not occur in the same time period, it is necessary to add a time for the CPU to be powered down to the log contents, so as to obtain a complete log information, for example, "xx minutes xx seconds at xx month xx day xx in xx year: power Lose Handled on CPU ", namely xx minute xx seconds when xx month xx day xx in year xx month, CPU has taken place the Power failure and Handled.
In other embodiments, because a software system is run inside the solid state disk, the log file may also be generated by a processor inside the solid state disk, and after the processor inside the solid state disk generates the log file, the log file is directly analyzed, and time information generated by the log content is added to the log content generated by the analysis, so as to generate complete log information.
Step S302, sending the log information to engineering equipment through a port, so that the engineering equipment sets a level for the log information according to the log content and caches the log information in a cache space.
After a problem occurs in the solid state disk, in order to save the time for positioning the problem, an engineer is required to set a level for the log information. After the log information is generated, the solid state disk sends the log information to engineering equipment through a port which establishes communication with the engineering equipment, the engineering equipment sets a level for the log information according to the log content of the log information after receiving the log information, and after an engineer sets the level, the solid state disk caches the log information in a cache space, for example, a cache register. .
In some other embodiments, before the solid state disk sends the log information to the engineering device, the solid state disk needs to establish a communication connection with the engineering device. An engineer connects the engineering equipment with the port of the solid state disk through a port connecting line, and sends a connecting instruction to the solid state disk after the port connecting line is connected, and the solid state disk establishes communication connection with the engineering equipment after receiving the connecting instruction. After the communication connection is established, when an engineer needs to set a level for the log information, the engineer sends a first request for obtaining the log information to the solid state disk through the engineering equipment, and after the solid state disk receives the first request sent by the engineering equipment, the solid state disk sends the log information to the engineering equipment through a port for establishing communication connection with the engineering equipment according to the first request.
Step S303, the log information in the cache space is sent to a corresponding memory to be stored according to the level.
In order to save time for engineers to locate problems with the solid state disk, different levels of log information need to be stored in different memories. When the solid state disk caches the log information in the buffer register, the solid state disk sends different log information to different memories for storage according to the level of the log information set by an engineer.
In some other embodiments, the level of the log information includes an abnormal severity level and an abnormal general level, the abnormal severity level is a level that affects normal operation of the solid state disk software system, and the abnormal general level is a level that does not affect normal operation of the solid state disk software system but affects operation speed of the solid state disk software system.
When the level of the log information set by an engineer is an abnormal serious level, the problem that the normal operation of the solid state disk software system is influenced currently exists in the solid state disk, the log information of the problem needs to be stored in time, and the problem that the log information is lost and cannot be solved in time is prevented. Therefore, for the log information with the log information level of the abnormal severity level in the buffer register, the log information is synchronously flushed to the NOR memory for storage in a synchronous flushing mode, and the synchronous flushing is performed when the log information enters the buffer register and is flushed to the NOR memory for storage. For example, the current log information is: "[ error ] xx year xx month xx day xx minute xx seconds: date lose "," xx years xx month xx day xx minutes xx seconds: date lose "represents that data loss occurs at xx minutes xx seconds when xx month xx is xx in xx years," [ error ] "represents that the level of the current log information is an abnormal severity level, and then the solid state disk synchronously brushes the log information to the NOR memory while the log information passes through the buffer register.
When the level of the log information set by an engineer is an abnormal general level, it indicates that the current solid state disk has no problem of influencing the normal operation of the solid state disk software system, but has a problem of influencing the operation speed of the software system, and the problem does not need to be dealt with immediately. And because the space of the NOR memory is relatively small, the log information of the general level is relatively more, the log information cannot be printed in the NOR memory, in addition, in order to quickly locate the problem, each log file does not need to be consulted, and the log information of the abnormal severe level and the log information of the abnormal general level need to be separately stored, therefore, the log information of the abnormal general level is printed in the NAND memory, meanwhile, in order to reduce the operation times of the NAND memory and avoid influencing IO data of the NAND memory, the log information of the abnormal general level is printed in the NAND memory in an asynchronous brushing mode, and the asynchronous brushing is to firstly store the log information in a buffer register until the space in the buffer register is fully occupied and then print the log information in the NAND memory. For example, the current log information is: "[ Warneng ] xx year xx month xx day xx minute xx seconds: date Repeat "," xx years xx month xx day xx minutes xx seconds: date Repeat represents that a data Repeat problem occurs at the time xx minutes xx seconds at xx month xx days xx in xx years, "[ Warning ]" represents that the level of the current log information is an abnormal general level, and then the log information is firstly stored and cached in a buffer register by a solid state disk while passing through the buffer register until the storage space in the buffer register is full, and then the log information is flushed to a NAND memory for storage.
In other embodiments, the buffer register, the NOR memory, and the NAND memory are all located in the solid state disk, that is, after an engineer sets a level for the log information, the solid state disk directly caches the log information in the buffer register, and for the log information of the abnormal severity level, the log information is synchronously flushed to the NOR memory for storage, and for the log information of the abnormal general level, the log information is flushed to the NAND memory for storage until the buffer register is full.
In some other embodiments, in order to ensure that the solid state disk can normally process the log information, the solid state disk further monitors the current state of the log information in real time, and controls the log information to perform a next link according to the current state of the log information. For example, when the solid state disk monitors that the current state of the log information is that the log information level needs to be set, the log information is sent to engineering equipment through a port which establishes communication with the engineering equipment, so that an engineer sets the level for the log information.
In other embodiments, in order to ensure that the log information is not lost, when the solid state disk is powered down, the solid state disk controls the log information in the buffer register to be flushed to the NAND storage, so that the log information in the buffer register is not lost under the condition of power down.
In other embodiments, after the solid state disk leaves the factory, a port for establishing a communication connection between the solid state disk and the engineering equipment is removed, so that after the solid state disk leaves the factory, a maintenance worker can establish a communication connection with the solid state disk through a server, and thus check log information in the solid state disk. When a maintainer needs to check the log information of the solid state disk, the maintainer establishes communication connection with the solid state disk through a server, and after the communication connection is established, the maintainer sends a second request for obtaining the log information to the solid state disk through the server, after the solid state disk receives the second request, the solid state disk uploads the log information in the NOR memory and the NAND memory to the server according to the second request, and after the server receives the log information, a log information file is generated and sent to the maintainer, so that the maintainer can check the log information in the log information file, and the solid state disk is maintained according to the log information.
In other embodiments, due to the limited storage space of the NOR memory and the NAND memory, when the log information generated by the solid state disk is excessive, that is, when the storage space of the NOR memory and the NAND memory is occupied by the log information, the solid state disk stores the log information in a cyclic overwriting manner, that is, according to the time information of the log information, the newly generated log information is substituted for the log information with the longest storage time. Therefore, the log information stored in the NOR memory and the log information stored in the NAND memory are both relatively new log information, and maintenance personnel can maintain the solid state disk according to the latest log information.
The embodiment of the invention has the advantages that the log file is analyzed through the solid state disk, time information is added into the analyzed log content to generate log information, and after the log information is generated, the log information is sent to the engineering equipment through a port which is in communication connection with the engineering equipment, so that an engineer sets the level of the log information. After the engineer sets the level, the log information is cached in a buffer register and stored in a different memory according to the level of the log information set by the engineer. And when the level of the log information is an abnormal serious level, synchronously brushing the log information to a NOR memory for storage, and when the log information is an abnormal general level, firstly storing the log information in a cache register, and when the storage space of the cache register is full, brushing the log information to the NAND memory for storage. After the solid state disk leaves a factory, a maintainer can establish communication connection with the solid state disk through a server and read log information in the NOR memory and the NAND memory, so that the solid state disk is maintained according to the log information. By the mode, an engineer can quickly locate the problems of the solid state disk through the level of the log information, the problem locating efficiency is improved, the log information does not need to be checked one by one, and the time is saved.
