Description
Technical field
The invention belongs to alarm management technical field in the telecommunication management network, relate in particular to a kind of alarm management method of performance optimization of background net management.
Background technology
The regulation field of network management comprises five functional in telecommunication management network (TMN) field: 1, configuration management; 2, alarm management; 3, performance management; 4, safety management; 5, accounting management.At present standard communications protocol commonly used is divided into two kinds of SNMP and CMIP in the network management system, snmp protocol especially, and short with its construction cycle, agreement realizes simple advantage, has become the de facto standard agreement of network management gradually.
The snmp protocol network management system adopts the Manager/Agent framework, and wherein background net management is as manager (Manager), and the foreground network element is as agency (Agent), and background net management and foreground network element adopt snmp protocol to communicate.Each foreground network element all has an independent IP address, sends and receive snmp message with the UDP host-host protocol.The foreground network element sends network element alarming or alarm recovery message to background net management by the Trap message that defines in the snmp protocol.
After background net management receives alarm (Trap) message, after the binding parameters such as alarm object sign (Trap OID), the Alarm Sequence Number that parsing wherein comprises, event type, following two kinds of common processing methods are arranged generally.
First kind be record this alarm in the database of background net management and instant playback in the current alarm list interface, the running status that the dimension personnel can bring in monitoring foreground network element by the client of background net management system is protected in operation.
Second kind be record this alarm in the alarm pond of background net management and instant playback in the current alarm list interface, the running status that the dimension personnel can bring in monitoring foreground network element by the client of background net management system is protected in operation.
Adopt these two kinds of schemes to cut both ways, can should be used for choosing different alert processing methods according to different webmasters generally speaking.
Adopt first kind of scheme, alarming processing efficient is lower, and the processing of an alarm information is made up of a plurality of steps, need handle as affairs.Consider thread-safe and transactional integrity, alarming processing generally all adopts single-threaded, if receive many alarm informations simultaneously, background net management is a serial process, therefore the processing time of wall scroll alarm just directly has influence on the efficient of alarming processing, and operating database is generally all more consuming time.So the shortcoming of first kind of scheme is that the processing time of every alarm information is long, advantage is because alarm has recorded in the database, be in permanent preservation state, even background net management restarts like this, these alarms also can exist, need only all warning information that just can get access to the foreground network element in the database, forward and backward alarm this moment may be inconsistent, and this can solve this problem by forward and backward alarm synchronously.
Adopt second kind of scheme, alarming processing efficient is than higher, because all belong to internal memory operation basically, the processing time of every alarm is fewer, so the alarming processing efficient of background net management than higher, is fit to the sort of higher system be compared in alarming processing time requirement.Alarm is to be kept in the alarm pond but the shortcoming of second kind of scheme is, if NM server restarts, then these warning information will have been lost, and must could be consistent with the alarm that guarantees forward and backward by forward and backward alarm synchronization operation.If there were a large amount of alarms on the foreground when NM server restarted, and these alarms all do not have to recover when starting, every alarm on foreground all needs to mail to background net management by Trap, this moment, the Synchronize Alarm message between forward and backward may be very many, when serious even can have influence on the reception of normal alarm information.
Summary of the invention
The contradiction that warning information blocked when technical problem to be solved by this invention was that high efficiency in the snmp protocol network management system alarming processing and NM server restart, a kind of high efficiency alert processing method is provided, this method had both combined the advantage of the two kinds of schemes in front, had avoided the shortcoming of the two kinds of schemes in front again.
In order to solve above technical problem, method of the present invention may further comprise the steps:
(a) after background net management starts, start a thread and monitor the alarm (Trap) that the foreground network element is sent;
(b) after background net management is received the alarm that the foreground network element sends, alarm is pressed in the alarm formation;
(c) after background net management starts, start a thread, be responsible for specially and check in the alarm formation whether alarm is arranged; If have, then call the alarm adapter; The alarm adapter converts alarm information to an alarm object, mails to the alarm information theme on the message server;
(d) alarm pond warning processing module and database warning processing module subscribed to the alarm information theme respectively, receive alarm information after, respectively the alarm object that comprises in the alarm information is recorded again in alarm pond, the database.
The step of described method (c) may further comprise the steps:
(c1) after background net management starts, start a thread, ceaselessly in the circular test alarm formation whether untreated alarm is arranged;
(c2), from the alarm formation, take out an alarm object if having;
(c3) attribute of analysis alarm object comprises alarm object sign (Trap OID), event type, bound values, Alarm Sequence Number;
(c4) in internal memory, obtain alarm level according to alarm object sign (Trap OID), and then generate an alarm object according to other several attributes;
(c5) alarm object that obtains is mail to the alarm information theme of alarm server.
Wherein, the information such as alarm level in the step (c4) start the back by NM server and are loaded into from database in the internal memory, and this can be avoided the back all to obtain information such as alarm level, the processing time that can accelerate every alarm in the database at every turn.
The step of described method (d) may further comprise the steps:
At first introduce the treatment step after alarm pond warning processing module receives alarm information below:
(d1) at first judge the event type of alarm object,, then be increased in the alarm pond if alarm; If alarm clearing, then the alarm object that Alarm Sequence Number is identical is deleted from the alarm pond;
(d2) carry out the processing of alarm propagation;
(d3) send out the message informing client and upgrade the current alarm list interface;
Introduce the treatment step after the database warning processing module receives alarm information below again:
(d4) at first judge the event type of alarm object, if the inner alarm information of sending is then abandoned this message;
(d5), then judge the event type of alarm object if the alarm information that the foreground network element is sent; If alarm then is increased in the database; If alarm clearing, then the alarm object that Alarm Sequence Number is identical is deleted from database.
Comprise alarm main thread and alarm worker thread in the alert processing method of the present invention.Wherein: the alarm main thread adopts aforementioned second kind of scheme, alarm is kept in the alarm pond, processing speed is than very fast like this, worker thread adopts aforementioned first kind of scheme simultaneously, alarm is kept in the database, can accomplish permanent preservation like this, so just can solve NM server and start the too much problem of back Synchronize Alarm message.These two threads all adopt the method for subscribing to the alarm information theme in addition, their mutual independent operatings, so the processing speed of this method basically can be similar with the speed that only adopts the operation of alarm pond.Can improve the alarming processing speed of background net management in the snmp protocol network management system so greatly, foreground network element when the minimizing NM server restarts mails to the quantity of the Synchronize Alarm message of background net management, thereby optimized the performance of background net management greatly, strengthened the alarm management function of background net management.
