A log data storage method and device

Abstract

The invention provides a storage method of journal data, and includes the steps that the journal data needed to be stored is obtained; whether the length of the journal data exceeds the length of a basic block of a presetting journal file is judged; the journal file includes the basic block and an expanding block which both have vested bytes; if exceeding, the journal data is recorded in the expanding block of the presetting journal file; if not exceeding, the journal data is recorded in the empty basic block of the journal file; each basic block is corresponding to a journal record. The invention creates the journal file in advance, and marks off the basic block and the expanding block in the journal file, general journal data can be directly stored in one basic block, and special long journal data can be stored in the expanding block, thereby avoiding from changing the length of the journal file when recording the journal data every time, improving the writing speed and reducing theIO pressure to the system.

Description

technical field [0001] The invention relates to the technical field of computer message processing, in particular to a method and a device for storing log data of a message processing system on a disk. Background technique [0002] A message processing system generally refers to a computer software system that helps users transfer messages between networks. The specific applications include e-mail systems, mobile phone short message gateways, and mobile phone MMS gateways. [0003] In the message processing system, the log module is mainly used to record the operation status of the entire system and user operation behaviors, etc. Each preset log record point in the system will generate a log message. With the operation of the system, the system will Continuously generate log information. The log information can be displayed on the terminal monitor that logs into the system. This method is mainly used for user debugging and checking the system status; the log information can...

Problems solved by technology

However, in practical applications, the above-mentioned method of writing log information to files has relatively large defects.

[0007]First of all, if frequently appending content to the log file will cause this kind of operation of updating file system information to occur frequently, and because the operation of appending file content and updating file system information is An inseparable process, which in turn reduces the writing speed of log files and increases the pressure on system IO (input and output), especially for message systems that require a large number of file operations

[0008]Secondly, the log file management method commonly used in the current system is to write the logs of the same day into a log file. This method will first bring the above-mentioned log file write The input speed decreases, which increases the IO pressure of the system; secondly, when there is a lot of log data to be recorded, the log file is too large to seriously slow down the opening speed of the file, which may further reduce the writing speed or browsing speed of the log file
