By using the layered printing method, a developer can track the execution of the I/O instruction according to the log information when analyzing the problem, and quickly analyze and locate the problem.
Example two
This embodiment specifically describes the method of the above embodiment. The embodiment provides a tgt log module layered printing method based on distributed storage, which divides the existing log information according to the software hierarchy to which the existing log information belongs, expands the hierarchy parameters, displays the corresponding state, the corresponding Target name, the Initior address, the instruction content, the request length and the corresponding thread information of an I/O instruction in the execution process, and increases a log hierarchy setting interface, so that a problem locator can clearly perceive the whole I/O execution process and quickly locate the problem, and the log printing requirement of the tgt module in a distributed storage system is met.
(1) When a data processing request is received and protocol layer processing is carried out, and information analyzed by each protocol layer is stored, level parameters of the protocol layer corresponding to the information are increased;
software layers are divided in the tgt module, and specific layer parameters are added in log printing interfaces of all layers, so that the tgt log module realizes information layering.
As shown in fig. 2, after receiving the request, the Target end enters an iScsi layer, parses out the Target name and initior address corresponding to the request in the layer, stores the Target name and initior address into a message structure body for context printing, and transmits an iScsi level parameter into a printing interface of the layer. And then entering an Scsi layer, transmitting Scsi level parameters in a printing interface of the Scsi layer, analyzing the Scsi instruction type, and converting the instruction type into a character string and printing the character string. Then, the Bs layer is entered, and the layer level parameters are added when the enqueue and the dequeue are instructed and the Bs layer level parameters are transmitted into the printing interface.
(2) When the log file is printed, printing information of a corresponding protocol layer according to the set hierarchical parameters needing to be printed;
and in the tgt module, a log level setting command is added, and logs can be selectively printed.
As shown in fig. 3, a tgt log level setting command is newly added in the storage system, the user selects the log level to be printed through the command, and the set level data is stored in the tgtd daemon process. When the program calls the printing interface, the level parameters transmitted by the printing interface are matched with the level data set through the command, if the condition is met, the printing is saved in the log file, otherwise, the printing is returned, the printing is not executed, and therefore, the printing of the log can be controlled through the log level command.
The log of the tgt module is managed by adopting a layered printing method, so that a user can clearly perceive the execution process of I/O execution and the passed software levels, and can selectively print the information of some software levels in a log file, thereby facilitating the problem positioning and information screening of the user.
In the embodiment of the invention, a concept of software hierarchy is introduced to hierarchy parameters in the tgt module, a path passed by an I/O instruction in an execution process and detailed information corresponding to the instruction are determined, a tgt log hierarchy setting interface is added, and a user can selectively print logs of certain hierarchies through the interface.
