Detailed Description
Example 1:
a configuration fault positioning method based on binary comparison of mirror images is characterized in that bottom layer mirror image data before and after a fault occurs are obtained, binary comparison is carried out to obtain a differential part, the differential part and upper and lower offset associated data of the differential part are decoded and restored into natural language symbols, and then fault positioning is achieved.
Establishing a configuration file knowledge base, and importing the known configuration files into the configuration file knowledge base; and sequencing the configuration files by taking the natural language symbols obtained by decoding as key words so as to accelerate fault matching and positioning.
Determining that the service is normally started each time, and immediately performing mirror image backup and recording the time of mirror image creation after checking that the core service can be used; when the service is found to be abnormal, mirror image backup is immediately carried out and mirror image creation time is recorded.
The invention deploys the application in the form of the virtual machine, thereby having the capability of acquiring the mirror image of the virtual machine at any time; and obtaining the virtual machine mirror image between the last time before and after the problem and carrying out binary comparison. And decoding the data of the differential part and the up-down deviation part to obtain the human scale natural language characters. And accumulating a configuration file knowledge base (natural language), comparing the keywords, arranging the possible problem configuration points according to the probability, and gradually checking from high to low.
The virtual machine and the physical machine are different in that a hypervisor capable of comprehensively controlling the virtual machine and various devices (including a disk) on the bottom layer virtualized by the virtual machine exists on the virtual machine, and the hypervisor can easily acquire the whole image information of the virtual machine, namely all relevant binary data of the virtual machine.
The so-called binary comparison is binary differentiation of data on disk images before and after a problem compared with the data on the disk images, and is also the most efficient comparison method for computers. All data stored/transmitted by a computer exist in a binary mode, and the data in the form conforms to the transmission and storage of magnetic/electric signals of computer hardware principles, but is not beneficial to human reading and understanding.
The computer can only process numbers, all information needs to be encoded into the digital information which can be processed by the computer before the computer processes, for example, a process of converting an English character string of pro = http into an ascii code number string of 11211411161104116116112 in a 'natural language symbol' can be simply understood as an encoding process, and a process of reducing the ascii code number string into the character string pro = http can be simply understood as decoding.
It should be noted here that english characters are few (as in the following ascii code table), so that 128 numbers in total can be covered by using a small number of codes (0-127), while chinese characters are many (3500 common chinese characters), and the coding mode is obviously different from english, but the principle is the same, so the details are not referred to here.
The natural language symbol refers to a language character symbol which can be understood by human, such as a common language of English/Chinese, for example, a configuration item of a certain configuration file has such a section: pro = http, pro is an abbreviation for protocol, pro = http, meaning that the communication protocol is configured as http protocol, at which point communication may fail if an attempt is made to communicate with the server using a non-http protocol.
For binary alignment:
taking the example of the character string pro = http, the storage of the character string in the disk is as follows:
01110000 01110010 01101111 00111101 01101000 01110100 01110100 01110000
then we introduce another string pro = htpp (e.g. a careless error-filled character) which is stored in disk as follows:
01110000 01110010 01101111 00111101 01101000 01110100 01110000 01110000
comparing the two strings of 01 codes according to bit bits, taking 1 if the same bit is the same, taking 0 if the same bit is different, and calculating the result as follows:
11111111 11111111 11111111 11111111 11111111 11111111 11111011 11111111
it can be seen that a 0 appears, indicating a change in the profile contents.
We see that the last but one byte (8 bits are one byte) is abnormal, then we decode the last but one byte of two bit strings participating in comparison first into natural language, they correspond to letter characters t and p respectively; only two letters of t and p are difficult to see the relevant semantic meaning of the associated configuration file, so that the bit strings before and after the two key points are further decoded until the two key points are restored to two natural language strings of pro = http and pro = htpp, and thus, a maintainer familiar with the configuration file can see the problem.
It can be seen that when a fine error trail is in hundreds of natural language characters, it is difficult to see at a glance in actual operation, and when we do not pay attention to how to encode in the upper layer, but only pay attention to bit difference and bit difference stored in the bottom layer, differentiation can be seen equally, and at this time, we pay attention to the natural language semantic meaning causing the error, and the efficiency is much higher.
We put pro's keyword into the knowledge base, and when finding the keyword during decoding, we will prompt the problem troubleshooting personnel, and the keyword exists in which configuration files, what the files have, how the keyword should be configured, and so on, thereby troubleshooting the problem more quickly and giving more physical activity to the computer to do.
The invention does not pay attention to how the upper file system organizes the configuration files, does not pay attention to information such as content and position of the files, directly compares binary data stored in disk images of the virtual machine before and after the problem, pays attention to a differentiated part firstly, and then restores the binary data into natural language characters, so that the problem is directly reached, and the production efficiency is improved.
