Technical field

The present invention relates generally to report record data from computer system.The present invention is especially a kind of can be with the method that is used to create subsystem of software or hardware mode realization, and this method allows selectivity dissemination system to record a plurality of networking machines.

Background technology

In most of large scale system, be necessary to utilize auxiliary body to come performance, activity and the behavior of the major function of supervisory system.In this technology, use a kind of method that is called as record usually.

Usually, this recording method comprise produce a series of corresponding to occurring in the transaction in this system or the recording messages of incident.These recording messages typically use certain formal structure or form, and purpose is to make things convenient for the other system information extraction, but seldom construct them in some system.

High performance transaction system produces the magnanimity recorded information.Because the speed of the quantity of information and the information of generation is recovered this recorded information and can greatly be increased the weight of the burden of these systems, and limits its overall performance.Yet, importantly can recover this information, because in many application, use it for such as the purposes that produces charge information.Thereby speed and reliability are very important.

Because the speed height of the big and information of generation of the quantity of recorded information is handled very difficulty of this information in these high performance transaction systems.Or rather, except simply recorded information being dumped to a single output unit, do that anything is all very difficult usually.As a result, prior art is only done---recorded information is dumped to a single output unit, as a control desk demonstration, a text, a database or a printer.Recording messages is not filtered, selects, distributes or other processing.After recorded information being dumped to a single output unit, do further processing again.

Yet the mode of this processing recorded information may have problem.At first, here, the problem that has aftertreatment.Because only output record information of register system must utilize other system to carry out aftertreatment.These systems must coordinate with register system, and coordinate mutually possibly, so that obtain redundancy, load balance, filtration or other processing of recorded information.Utilize these other systems need increase the development time, increase hardware resource and more maintainer.

Another problem is the risk of losing recorded information.Put because information all is dumped to a unit because the fault of destination device or even at the bottleneck that information is forwarded in the destination device, this may take risks.Web server, network agent etc. are being produced in the situation of recorded information, and bottleneck problem is particularly relevant, because may be restricted at the available bandwidth of this information of transmission over networks.

Summary of the invention

Above one or more problems of summarizing can solve by various embodiment of the present invention.In a broad sense, the present invention includes the recorded information that is used for a kind of system and optionally be distributed to a plurality of clients to obtain the system and method for improved reliability and performance.

With reference to Fig. 3, the figure shows basic architecture according to the register system of one embodiment of the present of invention.As shown in this Fig, executive logging subsystem 200 in transaction system 100.When in transaction system 100 transaction taking place, by recording subsystem 200 monitoring tradings.When detecting recordable transaction, recording subsystem 200 determines whether this transaction is in the recording messages set of any subscription client (410,510,512,514,610,612,614) request.If in these set, will not produce recording messages.If in these set,, and on network abstraction layer 300, it is transferred to the client of request with the recording messages that produces corresponding to this transaction.Network abstraction layer 300 comprises the network path between register system and the client in fact.

Single client 410 can be subscribed to all or some subclass 400 of recording messages.One group of client (510,512,514) can be united the same subsets (500,502,504) of subscribing to record, and they are handled respectively, thereby realizes that high level redundance prevents the fault of any one client process.Another group client (610,612,614) can be united the different subclass (600,602,604) of subscribing to record.Each of these clients is handled its subclass in the mode identical with other clients.By this way, the neither one client need be handled all recorded informations alone, and can obtain high level performance, and the neither one client can be collapsed.

With reference to Fig. 4, the figure shows method according to one embodiment of the present of invention.In this embodiment, one or more clients can be subscribed to recording subsystem so that obtain recorded information.Therefore, in the first step of this method, the client subscription recording subsystem.Client has been determined transaction to the subscription of recording subsystem, will distribute the recorded information of this transaction and the form of recorded information to client.After recording subsystem was finished the subscription of client, the subscription standard of client was to being filtered by each transaction of recording subsystem monitoring.If any transaction all meets these standards, will produce the recording messages of this transaction to distribute to client.The subscription of client can determine to be included in the Level of Detail of recording messages.Can only point out the particular transaction that taken place such as, recording messages, perhaps point out other information such as exchange hour etc.If no longer need client receiving record information, the client recording subsystem that can cancel subscriptions.

In one embodiment, the transaction system that is connected with recording subsystem comprises a webserver.Submit on January 14th, 2003 by Jeremy S.de Bonet, Todd A.Stiers and Phillip Alvelda VII, name is called the U.S. Patent application No.__ (attorney No.IDET 1130-1) of " being used for using shared resource and different application to finish transaction method and system " and describes a typical webserver in detail, it is incorporated herein by reference, as stating that at this it in full.

The webserver is realized register system and transaction system.The webserver is accepted the connection from the client of recording subsystem, and according to the subscription filter record information of each client.Therefore, server is configured to accept subscription information, subscription information is included as the standard to the client distribution will be concluded the business or the recorded information filtration is used.Can the service regeulations expression formula, numeral relatively, the mode of string coupling or other filter record information stipulates these standards.Server also is configured to keep the information about client communication, filter criteria be connected, so, can with the expectation recorded information be distributed to each client.

Network server can be accepted the connection from a plurality of clients.Each of these clients can be stipulated the subscription standard of oneself.Based on subscription standard separately, the webserver can be distributed same recorded information collection, information set, exclusive message collection or combination in any wherein overlapping but inequality to client.Thus, system is by selecting the feasible feature that can have such as redundant recording and load balance of suitable subscription standard for each client.

In one embodiment, the record client can be dynamically subscribed to and is cancelled subscriptions to recording subsystem.When recording subsystem moves continuously, monitoring trading and when handling these transaction according to client subscription, client subscription itself can change.When recording subsystem brings into operation, can there be client subscription.After the subsystem operation, two clients can be subscribed to, such as, each client receives the recorded information (load balance between two clients is provided thus) of half.After, can be desirably between three clients and carry out load balance, therefore, two clients at first can cancel subscriptions, and subscribe to again then to receive 1/3rd recorded informations.The 3rd client also will be subscribed to receive 1/3rd recorded informations.As selection, system can stipulate to cancel subscriptions to revise the subscription standard.

With reference to Fig. 5, the figure shows process flow diagram according to the method for one embodiment of the present of invention.In this embodiment, in recording subsystem, realize this method.This method comprises that in fact detection can produce the incident of recorded information, then, each client is determined whether client expects the recorded information of this incident, and if the expectation record, will produce suitable recording messages and recording messages is sent to client.

In this embodiment, on the basis of incident one by one, realize this method.That is to say that when each incident took place, recording subsystem detected this incident and begins to determine for that incident distributed recorder information how in system.At first, recording subsystem determines whether that any record client has subscription.If do not have the client of subscription, will not produce or distributed recorder information.If have the client of subscribing to,, handle this incident one by one then for each client to recording subsystem.

Subscribe to client for each, at first this incident and subscription standard corresponding to this client are compared.For given client, if this incident with that standard of that client defined is complementary, then produce recording messages corresponding to this incident.Therefore, according to the subscription standard filter record information of client.Recording subsystem is according to the demand formatted record message of that specific client subscription.Then, the recording messages that produces is sent to that client.Client for each subscription repeats this process.

As implied above, as typical embodiment, method of the present invention can realize in the network agent server.In such embodiments, client can communicate by Internet Protocol and recording subsystem.The preferred HTTP (HTML (Hypertext Markup Language)) that uses still also can use other agreement.

Though embodiments of the invention described herein mainly concentrate in the based on network realization, this client that needs not to be recording subsystem and it is by the situation of network detach.In an optional embodiment, each can be the assembly of the system that is recorded for recording subsystem and client.In another optional embodiment, some clients can be the assemblies of system, yet other clients can reside among the system with this system independence.Also has some other change.

Above-mentioned embodiments of the invention " are pulled out " information from recording subsystem.That is to say that recording subsystem offers client in response to the request to this information with recorded information.Such as, client subscription recording subsystem (that is, the request recorded information), and recording subsystem offers client in response to subscribing to (request) with information.In certain embodiments, client can be thought the lasting request of the information of pulling out to the subscription of recording subsystem from subsystem, yet client can be asked in other embodiments to recorded information individually.Push information the prior art systems of corresponding destination to from recording subsystem though this special characteristic (pulling out recorded information) is different from, should be noted that some embodiments of the present invention can be configured to push recorded information to client.Such as, an embodiment can be configured to recorded information is filtered and it is distributed to a large amount of clients and does not consider the request that client is sent.In such embodiment, recording subsystem can be configured to by only (supposing n client arranged for each client here the distribution of information of every n incident, and the subclass of recorded information is offset, and makes their mutual exclusions) between all available client ends, carry out load balance.

Though the expection embodiments of the invention can make client can avoid causing collapse by too much recorded information, might given client be difficult to catch up with the message number that is distributed to it.Therefore, what may expect is to implement a buffer zone, can be accepted by client until this information with stored record information.In one embodiment, buffer zone can be finished in recording subsystem.Buffer zone can be lined up recorded information for clients corresponding, makes through this information being transmitted after the configurable delay.Such buffer zone also can be used for cumulative record information, so, can with this information in force rather than patch transfer to client, reduced expense thus.

In some embodiments of the invention, recording subsystem is configured to provide unique identifier to the recorded information that sends client to.Finish at configuration-system under the situation of load balance, this may be particularly useful.When the subclass of the recorded information that will be transferred to different clients makes up, use unique identifier that duplicate message is eliminated.

Various embodiment of the present invention can provide many aspects that are better than the prior art register system.As mentioned above, prior art systems only identified event and the recorded information that all are corresponding is dumped to single storage unit.Destination device collapses because of the mass data that sends it to and is not uncommon in such system.Attempting to obtain all info class at single destination device is similar to and attempts to drink water from fire hose---and a part wherein can be lost usually.Therefore, usually some is unreliable for these register systems, and the performance that has is lower than desired performance.Various embodiment of the present invention can provide the ability of obtaining any high level reliability and performance, and needn't change the recording subsystem of bottom.This mainly is to finish by the ability of finishing load balance and the enough information of redundant recording.

In a kind of environment, can be configured to distribute same recorded information this recording subsystem to a plurality of clients.This can finish by the same subsets that each that makes these clients is all subscribed to recorded information.The redundancy of information is collected and is minimized because intrasystem fault causes the possibility of drop-out.Such as, if one of them client experiences fault and loses some recorded informations, probably one of them of other clients do not experience fault and therefore obtains the information that another client is lost.The reliability of total system can be brought up to any rank (reliability) by increasing the client terminal quantity that receives redundant information as 99.9999%.

In a kind of environment, can be configured recorded information being divided into the mutual exclusion subclass this recording subsystem, and each subclass is sent to different clients.System can realize the load balance between the client by this way.Reduce the possibility that information that any one client is received is collapsed by the load between the balance client (that is distributed recorder information).Moreover, this cause fault and/the lower possibility of loss of data, cause higher reliability again.The load that reduces also allows each client with higher performance class operation.Recording subsystem itself also can have the performance of improvement, because it needn't be concerned about that client catches up with the ability of recorded information.

Should be pointed out that the present invention can be reduced in the upward bandwidth demand relevant with transmission log information of network connection by the information of filtering to each client distribution except improve the reliability and the performance of system by redundance and load balance.Because each client only receives the information that meets the standard of that client defined, network between this client and recording subsystem connects, with as carried out in the prior art all recorded informations be transferred to single destination compare, can reduce bandwidth demand.Even distribute all recorded informations, typically it is distributed to a plurality of clients, so, if give single client with all information transmission, will be littler in the load that any one network to these clients connects.Therefore, might eliminate as in network bottleneck problem that prior art met with.

Filter record information not only under the situation of redundant and load balance, and under the situation of the unwanted data of elimination, all is useful.In some instances, though can expect to write down each incident (as the transaction that can charge), normally do not need the situation of partial record information.Such as, can be configured to write down certain class incident system in case always need this information, still there is no need to have all the time this information.This information can be useful to diagnostic uses, if but normal this information of system's operation can be unnecessary.Embodiments of the invention can allow certain useful at that time class recorded information of client-requested, and abandon other current unnecessary recorded information.Equally, client can be selected the Level of Detail of recorded information because some the time some details useful and other details are useless.Just avoided collecting and storing the problem of unnecessary information, and the letter sorting recorded information is with the problem of sign useful part and nonuseable part like this.This can improve system performance fully.

More than described about specific embodiment can be by benefit provided by the invention and advantage.These benefits and advantage and any element that may cause them to take place or become clearer and more definite or restriction will can not be interpreted as the feature of key, the essential or essence of any or all claims.As used herein, term " comprises ", " comprising " or its any other the distortion, be interpreted as non-element or the restriction of following those terms that exclusively comprise.Therefore, comprise that system, method or other embodiment of one group of unit is not limited to only be those assemblies, but comprise other unit that embodiment that clearly do not list or required for protection is intrinsic.

Though invention has been described with reference to specific embodiment, be to be understood that embodiment is illustrative, and invention scope is not limited to these embodiment.The above embodiments are carried out some changes, revised, add and improve is possible.Expect that these changes, modification, interpolation and improvement drop on as in the invention scope that describes in detail in following claims.

This method can comprise with the second solicit operation plug-in module that is used for second application program (piece 924) replaces the first solicit operation plug-in module.Such as, superfine user can visit the webpage that some domestic consumers can not visit.If domestic consumer asks superfine webpage, the second solicit operation plug-in module can guide this domestic consumer to have another webpage of correct access right to this domestic consumer.

This method also can comprise with the second content operation plug-in module that is used for second application program (piece 926) replaces first content operation plug-in module.Superfine user's window can only have 10% to be taken by advertisement, and the window of domestic consumer has 50% and taken by advertisement.The second content operational module can be rearranged form to allow more advertising space to recovering content.The second content operational module can also access shared resources to obtain advertisement and to follow the tracks of and used which advertisement.The webpage optimization that device (desk-top computer to cell phone etc.) is relevant can realize by inserting a module, and being provided with that this module utilization initiates that the special device of initial request develops carried out code conversion to content.

After one or two of replacement request operational module and content operation module, this method also can comprise utilizes second group of plug-in module (piece 942) to carry out second application program.

Though notice that these embodiment concentrate on more and replace particular module, in other embodiments, those modules can produce by the code that editor is used in the respective modules in first group of first application program.

After finishing watching this standard, the technician can understand and utilize the identical network agreement, only in the solicit operation position, content requests position or this two kinds of positions all insert new plug-in module and can develop diverse application program.

In other embodiments, this method and system can be used for almost any other network service.For instance, client computer 120 can be initiated request to the information of the database that is positioned at server end computing machine 160.This request can be handled with the request mode that is similar to webpage.If the user does not possess the appropriate permission to the information in all requests, the solicit operation module can only ask the user to have the proprietorial information of visit, and perhaps the content operation module is added information, and the statement user does not possess the proper right to use to some or all information.

In another embodiment, multi-protocols software architecture and plug-in module can be installed in client computer 120 or server end computing machine 160.Module in the not all Agent Computer 140 all is that client computer 120 or server end computing machine 160 are required.Authorization module 3204,3404 and 3604 can not use or encode and allow to authorize (always being authorized to) at client computer 120.Content operation module 3210,3410 and 3610 can be can't help server end computing machine 160 and be used.After finishing watching this standard, the technician can determine which module is required and which module is can remove or circuitous (module exist but do not carry out by this information any other is effectively movable).

Component software can be designed to the ability of maximization use shared resource when minimizing the code quantity that is used for the application-specific operation.Therefore, relatively little plug-in module (than shared resource) can be used to visit the shared resource shown in the plane under this module.By this way, than the art methods that writes or copy and revise whole procedure for specific protocol, for new agreement needs code still less.For the application program with same agreement, specific coding requires can be still less.In addition, because coding requirement reduces, agreement more may be supported, therefore, can produce agreement for have the agreement of lacking the user relatively than other agreements.Than handling some current art methods with the problem of the different application of identical or different agreements, this method and system is all more effective on practice and cost.

More than with regard to specific embodiment the solution of benefit, other advantages and problem has been described.Yet, can cause the solution of the generation of any benefit, other advantages, solution or these benefits that become clearer and more definite, other advantages, problem and key, essential or essential characteristic or the unit that any or all claim will not thought in any unit.
