Embodiment
Be example with network element device in the telecom transmissioning equipment below, the embodiment of the invention is elaborated.
Fig. 1 is a real-time monitoring system schematic diagram of the present invention.As shown in Figure 1, concentrate monitoring equipment 110 to be connected real-time monitoring remote embedded equipment 120 with remote embedded system 120 by network 130.
In remote embedded system 120 inside, needs according to function and system, add the output monitoring information at the message Issuing Office of Communication Layer, detect the output monitoring information that adds Exception Type when unusual, regularly export the monitoring information of internal memory operating position in all systems; The output monitoring information that adds the flow process type at system core flow process place, or the like.Can add useful monitoring information at the inlet/outlet or any place of inside middle of any function as required.
When adding the output monitoring information, need classify these information.Sorting technique is divided by each module.Communication module for example, security module, business module, database module etc., the output information of each module has the type code of oneself.
Further refinement is divided into a plurality of grades to the output information of each module simultaneously.For example in the communication module, information type can be divided into 2 grades again, and the information of the high expression output of grade is very important, and the output information that grade is low is not very important under certain conditions, so just can realize output information selectively.
The normal one section sequence code carrying out of handling process executable code representation program among Fig. 2 adds the output monitoring information on the front and back of this code or middle key point, can access the current code executing location behind the operation for embedded system.Function detection point executable code is represented the one section code of embedded system to certain Function detection, adds the output monitoring information after this code, can export the Function detection result come in the mode of monitoring information.Monitoring information in each task by compiling and linking the executable code that becomes remote embedded system, when system moves in each task, when carrying out this executable code, is begun to export monitoring information.
Because the restriction of embedded system 120 network bandwidth resources, concentrated monitoring equipment 110 is provided with the mask word of remote equipment reporting information type, the type of the class output information that each bit of mask word is corresponding above-mentioned.Remote embedded system 120 reports the information of needs according to mask word.
For example, the high-grade information type of communication module is encoded to 0x00000010, and communication module inferior grade information type is encoded to 0x00000020, obtain the high-grade output information of communication module, and it is 0x00000010 that mask word can be set.If obtain the high low priority of communication module, it is 0x00000030 that mask word can be set.
Fig. 3 is the schematic flow sheet of remote embedded system output monitoring information.As shown in Figure 3, remote embedded system 120 and concentrated monitoring equipment 110 adopt the TCP communication modes.Remote embedded system 120 at certain port of reserving in advance, is waited for the connection of concentrating monitoring equipment 110 clients as the server end of TCP communication.
In the remote embedded system 120 current task run processes that are scheduled, when carrying out output monitoring information executable code, at first judge to start sign, if output is not then carried out in not success.If successful connection then judges whether output according to mask word,, then do not carry out if do not export.If need the monitoring information of type, monitoring information is sent in the message queue of transmitting supervisory information.As shown in Figure 4.
The task of remote embedded system 120 transmitting supervisory information is taken out the monitoring information that will send from message queue, the string length that adds monitoring information in the front of monitoring information, the back is the character string of the monitoring information that will send, and sends to this message format and concentrates monitoring equipment 110.
Concentrate monitoring equipment 110 from the monitoring information message that network receiving remote embedded system 120 sends, press the format analysis of message, just can show the current remote equipment monitoring information that receives in real time.Can be saved in information in the file simultaneously, for the ruuning situation of long-term observation remote equipment.
Concentrate monitoring equipment 110 when not needing to monitor embedded system, the connection between disconnection and the embedded system.The connection situation of remote embedded system 120 real-time detection set monitoring equipments 110 disconnects if concentrate monitoring equipment to connect, and remote embedded system 120 is cancelled the task of transmitting supervisory information and started sign.Continue to wait for the connection of remote centralized monitoring equipment 110 clients.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; being familiar with those of ordinary skill in the art ought can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
