Description
Technical field
The present invention relates to the network communications technology, be specifically related to warning data acquisition method in the network communicating system and the server and client side in the warning data acquisition system.
Background technology
In recent years, along with the expansion day by day of scope of the enterprise, the client of same enterprise distributes increasingly extensive, and the affiliate is also increasing, and this becomes the speed of geometric progression to rise with regard to the network size that causes the intranet user.Understand the enterprise network failure condition timely and effectively, for ensureing that customer service is most important.
At present, the warning data acquisition system that various structures occurred.This system is responsible for obtaining the network equipment of being managed and presets the original alarm information that alarm event sends because of triggering, and obtains alarm data by statistics and offers the user.The alarm data that the warning data acquisition system provides can effectively help the user to understand the practical operation situation of current network.
Fig. 1 shows existing a kind of widely used warning data acquisition system based on browser/server (Browser/Server) structure, and the warning data acquisition system of this structure adopts the application program of network (Web) application program as server side and client-side.The server of operation Web program is called Web server, and the client browser of operation Web program is called Web browser.Web server can provide service for a plurality of Web browsers simultaneously.
Referring to Fig. 1, after warning system started, the warning information of Web server monitoring managed devices, collection managed devices also was stored in the local data base of Web server.Behind the Web browser of the user's logging on client with administration authority, Web browser sends the alarm data request to Web server, and Web server is notified in which Client-initiated request simultaneously is.After Web server is received the alarm data request, obtain user right from server self, according to the user right inquiry local data base that obtains, obtain the original alarm information under the user right, then according to the original alarm Information Statistics alarm data that inquires, generate the alarming page of HTML (HTML, the Hyper TextMark Language) form that comprises statistics at last, and send to the client of filing a request.The Web browser of client shows received alarming page.Behind the Web browser display alarm interface, the user just can see the alarm data of each managed devices under its authority.During Web browser display alarm interface, can provide multiple display format for the user by acousto-optic hint.
Above-mentioned process according to original alarm information calculations alarm data is to filter out according to alarm data to meet all kinds of warning information quantity that impose a condition, and all kinds of new filter process to warning information quantity that produces between this visit and the last visit.So-called alarm data is meant the warning information quantity statistics value of adding up all kinds of alarm quantities, each rank alarm quantity or the like according to warning information.
Above-mentioned user right is by server admin, and the indication user can inquire about the authority information of which managed devices.After user right changes, need to nullify and lay equal stress on new login and initiate the alarm data request, just can see the alarm data under the new authority.And after user's login,, need the control key that refreshes on the manual triggers alarm interface if up-to-date alarm data is obtained in hope, at this moment, Web browser sends the alarm data request to Web server again, receives alarm interface and the demonstration returned then.
Existing warning data acquisition scheme has following shortcoming:
At first, carry out at server end according to the operation of original alarm Information Statistics alarm data.Under the situation big in network size, that managed devices is more, the original alarm information content is huge, during each client-requested data, all will carry out a statistical operation at original alarm information, and therefore each statistics all consumes a large amount of server resources.If client frequently sends request to server, then can increase the computation burden of server greatly.When warning information breaks out, the execution storage operation that server stores original alarm database of information will not stopped, bear very heavy, if a plurality of user captures are arranged this moment, then server also needs to carry out simultaneously the operation of Query Database, and the concurrent database that may cause of a large amount of storages and query manipulation can't respond.Certainly, also have server that original alarm information is sent to the warning data acquisition system of client by the client statistics at present, still, the quantity of original alarm data is huge, and the data between the server to client end send will take massive band width.
Secondly, the warning data acquisition scheme shown in Fig. 1, when having only user capture or user's manual refreshing page, client just can be obtained up-to-date alarm data, so the alarm data renewal is untimely, can't support user's network management effectively.
In addition, with acoustooptic form display alarm data the time, utilize the third party's media player control that is embedded in Web browser to play acousto-optic to be shown usually.But, third party's media player is subjected to the constraint of client operating system, browser tenability, system developer must be considered the compatibility of different operating system, different browsers, also need consider the version compatibility of third party's media play control simultaneously.

Embodiment
In order to alleviate load of server, the present invention shares client with the part operation in the alarm data statistics.The statistics part of sharing client is relevant with user right, and the statistics part of staying server end is irrelevant with user right.
For the statistical operation of Differentiated Services device end and the statistical operation of client, below server is carried out be called rough estimates with the irrelevant statistical operation of user right, the statistics of client is called statistics based on user right.
By as can be known, comprise according to the filter operation of user right with according to pre-conditioned statistical operation according to the process of original alarm information acquisition alarm data to the analysis of server statistical operation in the prior art.Filter operation according to user right is relevant with user right, and the original alarm information that the user right difference filters out is all different, therefore, the filter operation according to user right can be shared client process.
And during according to pre-conditioned statistical operation, need the quantity of all kinds of warning information of each managed devices correspondence of statistics earlier, for different user, this operation is identical, irrelevant with user right, therefore the operation of adding up all kinds of warning information quantity of each managed devices correspondence can be retained in server end.
In pre-conditioned statistical operation, after the quantity of all kinds of warning information of each managed devices correspondence of statistics, just can count the alarm datas such as all kinds of warning information quantity, all class warning information quantity of some managed devices of all managed devices that this user right can check according to user right.As seen, it is relevant with user right to obtain pre-conditioned statistical value at last, therefore client process is shared in this operation.
Based on above analysis, the server of the embodiment of the invention obtains the original alarm information of managed devices and carries out and the irrelevant statistics of user right, obtains the rough estimates alarm data; Client is obtained the rough estimates alarm data from server after user login, and according to the user right of login user, and the rough estimates alarm data that obtains is carried out statistics based on user right, obtains meeting the alarm data that imposes a condition.After this, client can also show the alarm data that imposes a condition that meets that obtains by user interface.As seen, the embodiment of the invention is shared each client with the statistical operation relevant with user right, thereby has reduced load of server.And server only needs to send the rough estimates alarm data to client, and data volume is little, need not to take massive band width.
In addition, the embodiment of the invention is kept at the rough estimates result in the server local cache, when the user asks, adopts local cache directly to respond.Owing to need not to visit the local data base of storage original alarm data, even the alarm data outburst therefore occurs, also can utilize local cache to respond user's request fast and effectively, thereby further improve the overall performance of server.
Preferably, server by utilizing runs on the automatic regular polling thread on backstage and safeguards the local cache that stores the rough estimates alarm data, thereby the updating maintenance of rough estimates alarm data is separated with server response user requested operation, server response user request does not influence the maintenance of buffer memory, the maintenance of buffer memory can not take the device resource of server response user request yet, thereby has improved the overall performance of server.In addition, after the warning data acquisition system start-up, the each poll of server only obtains the alarm data of the managed devices that alarm data changes, and the Data Update local cache of employing variation, owing to the alarm data that does not have to change is not upgraded, reduce the operation of server, further improved the overall performance of server.
For client, in order to obtain alarm data timely, client is not only sent the request of obtaining alarm data when the user logins, further, after user login during log off, client is the request of timed sending alarm data also, and the rough estimates alarm data filtration according to the server response obtains meeting the alarm data that imposes a condition under the user right then, and refreshes display page.Thereby timely and effectively the fault of current network is carried out audible and visual alarm, support for the user provides management efficiently.
For the audible and visual alarm prompting is provided, the customer end adopted Applet technology to drawing alarm interface of the embodiment of the invention also provides acousto-optic hint.Applet can be translated as applet, is the JAVA small routine that moves in the client Web browser, is embedded within usually in the html page, is used to strengthen the display function of application program.Therefore Applet has the characteristic of the platform independence of JAVA own, thereby has satisfied operating system, the irrelevant requirement of browser.Therefore and all Applet all operate on the virtual machine of client, do not carry out any program of client terminal local, can not suffer the destruction of rogue program, and the user can secure access, and therefore, Applet has also guaranteed the fail safe of warning data acquisition.
Below in conjunction with the accompanying drawing embodiment that develops simultaneously, the implementation procedure of the various operations of server end of the present invention and client is described in detail.
Fig. 2 shows the process chart that server end in the embodiment of the invention obtains the rough estimates alarm data.As shown in Figure 2, this method may further comprise the steps:
Step 201: during warning data acquisition system start-up, server obtains the original alarm information of all managed devices, obtains the primary statistics alarm data after rough estimates, and is saved in the local cache.
In this step, rough estimates are and the irrelevant statistical operation of user right, are specially: the quantity that counts all kinds of warning information of each managed devices correspondence.The classification of warning information comprises alarm level classification, alarm type classification, alarm time classification, newly-increased alarm quantity class etc.For example, managed devices is A, B and C, and this step counts all kinds of warning information quantity of device A, B and C respectively so.
After the startup, below from step 202, server upgrades the value of each rough estimates alarm data in the local cache regularly according to newly-increased original alarm information.
Step 202: judge whether this poll time arrive, if then execution in step 204, otherwise execution in step 203.
Step 203: the monitoring managed devices, return step 202.
In the monitor procedure of this step, server receives the newly-increased original alarm information that managed devices is sent in real time, and according to newly-increased original alarm information updating rough estimates alarm data.Need to prove that the rough estimates alarm data of server real-time update is not the data that are kept in the local cache.
Step 204: judge whether the preliminary alarm data of managed devices changes in the polling interval between this poll and the last time poll, if, execution in step 205 and 206 then, otherwise, execution in step 206.
Step 205: the rough estimates alarm data after will changing is updated to local cache.
This step adopts the respective record in the up-to-date preliminary alarm data renewal local data base.For example, the statistical value of the x class warning information of device A becomes 100 by 7, and then the statistical value with the x class warning information of device A in the local cache is updated to 100.
Step 206: enter the next round poll, return step 202.
Preferably, the operation of above step 203 monitoring managed devices further comprises the state of server monitoring managed devices, the change of record managed devices state, and for example new managed devices adds, and existing managed devices withdraws from etc.Wherein, the implementation of managed devices being carried out condition monitoring is: after existing managed devices withdraws from preceding or new managed devices and is increased, the managed devices of state variation can be broadcasted deletion message or be increased message, when server receives the message of broadcasting, the state variation of record managed devices.
In this case, server can be handled according to the equipment variations state in real time, also can handle according to the equipment variations state when the 204 poll times of above-mentioned steps arrive.The specific implementation of handling is: in that to have new managed devices to add fashionable, obtain the original alarm information of new managed devices, carry out and statistics that user right is irrelevant, obtain the rough estimates alarm data of new managed devices correspondence, and be increased to local cache.When the existing device in place warning data acquisition system withdraws from, the rough estimates alarm data that withdraws from the equipment correspondence is deleted from described local cache.The reason that existing device withdraws from may be that equipment is worked as machine, and perhaps equipment is deleted by the keeper.
Fig. 3 is the flow chart of server end customer in response end alarm data request in the embodiment of the invention.As shown in Figure 3, this method may further comprise the steps:
Step 301: server end receives client because of the user logins the alarm data request of transmission, comprises the user name of login user in this alarm data request.
Step 302: server obtains user right according to the user name of login user.
Step 303: from local cache, obtain all rough estimates alarm datas.
Step 304: the rough estimates alarm data that user right that step 302 is obtained and step 303 are obtained sends to the client of filing a request.
Because client is when the user logins first, self does not have Applet, therefore this step when server end sends to client with user right and rough estimates alarm data or before, further user interface and the Applet with html format sends to client, and client just can adopt the Applet of reception to draw the alarm interface and the alarm data of adding up is presented in the alarm interface by acousto-optic so.The downloading process of user interface and Applet program is disposable, promptly as long as the user once logined, does not just need to have downloaded again.
Step 305: server end receives the alarm data request of client timed sending after the user logins.
Step 306: the alarm data request that utilizes all the rough estimates alarm data responses in the local cache to receive.Above-mentioned steps 305 and 306 is carried out repeatedly, up to user's no longer alarm data request of logging off.
So far, this flow process finishes.
Fig. 4 is the process chart of client in the embodiment of the invention.As shown in Figure 4, this processing procedure may further comprise the steps:
Step 401: client detects the user when logining, and sends the alarm data request to server.
Step 402: the alarm data response that the client reception server returns.The user right that comprises initial statistics alarm data and login user in this alarm data response.
Step 403: the user right according to login user filters initial statistics alarm data, obtains the initial statistics alarm data that login user has authority to check.
Step 404: the initial statistics alarm data after filtering is carried out the statistics second time, obtain meeting the alarm data that imposes a condition, and statistics is presented on the alarm interface by acousto-optic.
Wherein, the computation rule of statistics all is in the program of being solidificated in imposing a condition for the second time, and by server maintenance, client can be downloaded computation rule and impose a condition from server.Impose a condition and include but not limited to: the sum of all kinds of warning information, the sum of each equipment all types warning information, all kinds of new quantity that produces between this visit and the last visit, the Alarm Classification that managed devices is newly-increased etc. to warning information.
Certainly, client also can provide various users optional control, needs with the inquiry of supporting the user.For example, provide the control of certain equipment all types warning information quantity of inquiry, inquire about the control of certain type warning information quantity of certain equipment, or the like.Above acousto-optic shows and the optional control of user all adopts Applet to be plotted on the alarm interface, thereby breaks away from the platform restriction, reaches operating system, the irrelevant requirement of browser.
Above step 403 and 404 operation be after the server rough estimates, carry out, based on the statistics of user right, thereby shared the burden of server end by client.
Step 405: judge regularly whether arrive update time, if then execution in step 406; Otherwise, continue execution in step 405.
Step 406: send the alarm data request to server.
Step 407: the rough estimates alarm data that reception server returns, filter according to the authority of login user again, and carry out the statistics second time, obtain meeting pre-conditioned alarm data.
Step 408: the pre-conditioned alarm data that meets that adopts step 407 to obtain refreshes the alarm interface.Return step 405.
So far, this flow process finishes.
The purpose that present embodiment timer access server also refreshes the alarm interface automatically is in time to obtain the alarm situation of managed devices, and the refresh operation at alarm interface is finished automatically without the user manually gets involved.In practice, can adopt information assignment process (MDP, Message Dispatch Process) message communicating mechanism to realize timed sending alarm data requested operation.
Preferably, after certain user's authority changed, client need be carried out the statistics based on new user right according to the alarm data that the authority that changes is returned server again, and refreshed the alarm interface automatically according to up-to-date data statistics result.The operation of change user right can be carried out by the user with high authority, user with high authority is at logging on client and after revising low rights user's authority, by client authority is revised message and send to server, server is revised information broadcast with authority and is given connected all clients, comprises the client of sending permission modification message.The client that receives authority modification message is all carried out based on the alarm data statistics of revising the back user right, and refreshes the alarm interface.Usually, the refresh operation after user right changes not is to carry out at once after obtaining alarm data, but will keep consistent with the refresh operation after client is regularly obtained alarm data.For example, the fixed time interval that client is obtained alarm data is 5s, and client 5s refreshes and once alarms the interface so, and after user right changed, client was calculated new alarm data, need wait until that the timing of 5s arrives, and just carries out refresh operation.Do so not only to have reduced and alarm the refresh operation that interface operation is realized, and when alarm takes place frequently, also can not alarm interface speech prompting and ring a situation of not stopping, can not influence user's operating experience to repaint.As seen, login user need not be nullified the new login of laying equal stress in the process that client recomputates, and also need not to trigger the control that refreshes on the interface, makes whole process finish in real time and automatically, has guaranteed the network management system safety of data.
For example, user 1 has the authority of revising authority, when user 2 checks the alarm data of device A, equipment B and equipment C in the user interface that client 2 shows, user 1 checks user 2 in client 1 the authority deletion of equipment C, at this moment, client 1 is revised message to the server sending permission, and server is revised message to this authority and broadcasted.After client 2 received that this authority is revised message, rough estimates alarm data that will be relevant with equipment C according to new authority of the user 2 filtered out, and carries out the statistics of alarm data again, and statistics finishes to upgrade automatically and alarms the interface.At this moment, the related data that does not comprise equipment C in the alarm interface after the renewal.
In order to realize above-mentioned warning data acquisition method, the present invention also provides a kind of warning data acquisition system.Fig. 5 shows the structural representation of warning data acquisition system in the embodiment of the invention.As shown in Figure 5, this warning data acquisition system comprises server 510 and client 520.
Wherein, server 510 is used to obtain the original alarm information of managed devices, carries out and statistics that user right is irrelevant, obtains the rough estimates alarm data.
Fig. 6 is a server in the embodiment of the invention, i.e. the structural representation of server 510 among Fig. 5.As shown in Figure 6, this server 510 comprises Alarm Unit 511, service unit 512, buffer unit 513 and original alarm information memory cell 514.Wherein,
Alarm Unit 511 is used to obtain the original alarm information of managed devices, and the original alarm information stores in original alarm information memory cell 514, is carried out the irrelevant statistics of user right to the original alarm information of obtaining, and obtains the rough estimates alarm data.Specifically, this Alarm Unit 511 obtains the original alarm information of all managed devices when the startup of server of place, carries out and the irrelevant statistics of user right, obtains the rough estimates alarm data; After startup, in real time according to the newly-increased acquired rough estimates alarm data of original alarm information updating.When service unit 512 inquiries, Alarm Unit 511 is added up alarm data with current preliminary and is offered service unit 512.
Service unit 512 is used for returning described rough estimates alarm data to client when the alarm data request that receives from client.
In order to improve the handling property of 512 pairs of concurrent events of service unit, service unit 512 specifically comprises processing module 532 that runs on the foreground and the poll module 531 that runs on the backstage.Poll module 531 is separate with processing module 532, does not disturb mutually.Wherein,
Poll module 531 is used for when startup of server, obtains all rough estimates alarm datas from Alarm Unit 511; After startup, utilize the poll thread, regularly query warning unit 511 obtains the rough estimates alarm data of variation, and adopts the corresponding record in the rough estimates alarm data renewal buffer unit 513 that changes.When obtaining the rough estimates alarm data of variation, can obtain all rough estimates alarm datas from Alarm Unit 511 earlier and judge again which has modification; Can also in Alarm Unit 511, the alarm data mark that is modified be come out, and when service unit 512 obtains, provide.
Processing module 532 is used to receive the alarm data request of client 520, all the rough estimates alarm datas in the return cache unit 513.Can also return simultaneously user right returning the rough estimates alarm data at the client login user.Carry out when certainly, returning the alarm data request that the operation of user right can only initiate first after the login of customer in response end subscriber.
Buffer unit 513 is used for buffer memory rough estimates alarm data.
Original alarm information memory cell 514 is used to store original alarm information.
In practice, for in real time according to the local cache of the variation update service device of managed devices resource, Alarm Unit 511 can further write down the equipment state change information of each managed devices, and in that to have new managed devices to add fashionable, Alarm Unit 511 not only recording equipment state change information obtains the original alarm information of new managed devices, carry out and the irrelevant statistics of user right, obtain the rough estimates alarm data of new managed devices correspondence, the original alarm information with new managed devices correspondence is saved in the original alarm information memory cell 514 simultaneously; When the existing managed devices in the system of place withdrawed from, Alarm Unit 511 can a recording equipment state change information.
In this case, poll module 531 is further obtained the equipment state change information of Alarm Unit 511 records, there have new managed devices to add in equipment state change information indication to be fashionable, and the rough estimates alarm data of new managed devices correspondence is sent to buffer unit 513; When the existing managed devices in the system of equipment state change information indication place withdraws from, the rough estimates alarm data of the managed devices correspondence that withdraws from is deleted from buffer unit 513.The above operation of upgrading local cache according to the equipment state change information can regularly be carried out during query warning unit 511 in poll module 531.
In practice, for real-time variation update service device local cache according to user right, processing module 532 is further when user right changes, revise message informing and all clients that its place server is connected by the broadcasting user authority, make client to add up alarm data again according to amended user right.
Fig. 7 is a client in the embodiment of the invention, i.e. the structural representation of client 520 among Fig. 5.As shown in Figure 7, client 520 comprises login unit 521, request unit 522, statistic unit 523 and display unit 524, wherein,
