Abstract
A fault information record method and a fault management system used for an access controller. The system comprises a main core, a secondary core and a memory, wherein a control signal output end of the main core is connected with a control signal input end of the secondary core, a fault storage signal output end of the main core is connected with a signal input end of the memory, and a fault storage signal output end of the memory is connected with a fault storage signal input end of the secondary core. When the main core fails, the secondary core replaces the main core to complete corresponding work, and meanwhile stores fault information of the main core and outputs the fault information to users. According to the method and the system provided by the invention, fault information can be recorded on site so that problems can be analyzed and positioned after the system is recovered.
Description
Technical field
The present invention relates to field of wireless communication, the malfunction monitoring register system of access controller especially, specifically a kind of access controller is with failure message recording method and Fault Management System.
Background technology
At present, field of wireless communication has specific access controller (AC) usually.Access controller (AC) will converge and insert Internet from the data of different AP, accomplish control function such as the AP configuration of devices is managed, wireless user's authentication, management and bandwidth, visit, switching, safety simultaneously.The situation analysis of on-the-spot AC common faults gets, and the kernel crash that important process is restarted, certain causes unusually etc. is a most common failure, and these faults have plenty of difficult reproduction.
?
Summary of the invention
The objective of the invention is to be difficult for the problem of reproduction, propose a kind of access controller with failure message recording method and Fault Management System to on-the-spot AC common faults.Can on-the-spot at that time failure message be noted through system of the present invention, so that system recovery post analysis, orientation problem.
Technical scheme of the present invention is:
A kind of access controller is used Fault Management System; It comprises main kernel, inferior kernel and storer, and the control signal output ends of described main kernel links to each other with the signal input end of inferior kernel, and the failed storage signal output part of main kernel links to each other with the signal input part of storer; The failed storage signal output part of storer links to each other with the failed storage signal input part of inferior kernel; When main kernel broke down, inferior interior nuclear subsitution master kernel was accomplished relevant work, simultaneously; Store the failure message of main kernel, export the user to.
The failed storage signal output part of of the present invention kernel exports the user to through interface module.
A kind of access controller is used the failure message recording method, adopts access controller to use Fault Management System, in access controller, increases time kernel; When main kernel broke down, inferior interior nuclear subsitution master kernel was accomplished relevant work, simultaneously; Store the failure message of main kernel, export the user to.
The present invention specifically may further comprise the steps:
1) in the access controller, outside main kernel, a kernel is set as the physical memory space of reserving;
2) when main kernel breaks down, it is in the headspace that the key message of fault is saved in time kernel;
3) restart system, turn inferior kernel simultaneously, load-on module;
4) when the user need transfer the failure message of main kernel, upper level applications was moved automatically, and the user is through the calling interface module, and the key message that reads fault in time kernel is to user's space, and was saved in the user control file;
5) restart system.
Of the present invention time kernel physical memory space is 512K.
Beneficial effect of the present invention:
Access controller of the present invention is used Fault Management System, through system of the present invention on-the-spot at that time failure message is noted, so that system recovery post analysis, orientation problem.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a processing flow chart of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in Figure 1, a kind of access controller is at first reserved 512k space time kernel with failure message recording method and Fault Management System; When main kernel breaks down; The crash key message that main kernel is broken down is saved in headspace, and the user adopts upper level applications to call, through interface module; In the inferior kernel of kernel spacing, transfer crash space key information and be saved in the file of user's space.
During practical implementation:
As shown in Figure 2, below with access controller (AC), introduce and realize that key message is saved in the method for the file of user's space.
In the present embodiment, specifically comprise following step:
Step 1 is installed the kexec-tools instrument, and kernel is caught in compiling system kernel and dump, revises grub.conf.
Step 2 is reserved 512 spaces, collects the crash key message to headspace.
Step 3, system kernel is restarted, and turns dump and catches kernel, load-on module.
Step 4, user space program is moved automatically, and the interface that calling module provides reads fixed address crash information, writes file, restarts system.
The present invention does not relate to all identical with the prior art prior art that maybe can adopt of part and realizes.
