Embodiment
Below in conjunction with drawings and the specific embodiments technical solution of the present invention is described in further detail.
At first, the present invention provides a kind of alarm report filter method, at Element management system EMS by northbound interface during to network management system NMS report and alarm or alarm clearing:
When EMS received the identical alarm of many of satisfying same alarm merger rule, EMS only reported the alarm that takes place first, and promptly report is alert.
When EMS received the alarm clearing of many identical alarm correspondences that satisfy same alarm merger rule, EMS only reported the alert corresponding alarm clearing of report.
This kind alarm report filter method is the present invention's alleged " alarm merger ".
Utilization alarm merger of the present invention reduces the method for alarm quantity, and its main thought is as follows:
Determine alarm merger rule on the EMS and the rule of judging identical alarm, under the condition of appointment, when EMS receives many identical alarms, EMS only reports that alarm (it is alert to be defined as report) that takes place the earliest, and all the other alarms (being defined as from alarm) do not report, and this method is called the alarm merger.
The rule of an alarm merger rule and an identical alarm of judgement has defined a kind of method that alarm is classified respectively, and report police is exactly the class alarm that meets first arrival of an alarm merger rule.Specifically, if an alarm meets an alarm merger rule, simultaneously according to the rule of judging identical alarm, the also not alarm identical before it arrives, then alarm headed by this alarm with it.If an alarm has met an alarm merger rule, just no longer judged other alarm merger rule.And satisfy alarm merger rule, and be judged as and the alert identical alarm of report, then be judged to be from alarm.
The first step, is at first determined " judging the rule of identical alarm ".
So-called " identical alarm " is meant according to the rule of judging identical alarm and thinks that comparing with the report police is the alarm of identical alarm, has only the alert identical alarm of report just can be merged.Judge the rule of identical alarm, determine, generally judge according to the attribute in the warning information according to the needs of practical application.According to the difference of concrete applicable cases, when determine judging identical alarm regular, determined rule has nothing in common with each other, and can be very simple, also can be more complicated, can be special-purpose, also can be general.
List the rule of the identical alarm of several judgements below:
(1) if alarm code is identical, then thinks identical alarm.
(2) identical as if the object instance (Object Instance) that produces the entity of alarming, alarm type (AlarmType), alarm level (perceived Severity), possible cause (probableCause), detailed reason (specific Problems) etc., then think identical alarm.
(3) by define a kind of general, rule is differentiated flexibly, be described below:
Article one, rule is the tabulation of attribute contrast condition, expression compare with the report police alarm of satisfying all properties contrast condition be report alert from alarm.The attribute contrast condition here comprises following content:
A) Property Name: the title of the attribute in the warning information that expression needs to contrast.
B) property value: expression meets the value of corresponding attribute from alarm of this rule.Can be constant, also can be to comprise Property Name and with the operation expression of the Property Name of @ symbol beginning, and the Property Name here represents from the value of this attribute of alarm, represents the value of alert corresponding this attribute of report with the Property Name of @ beginning.Property value also can be sky, and default value is got in expression, i.e. the alert value of report.
C) contrast operator: expression and report police compare the logical operator of use, can be the operable any legal logical operators of corresponding attribute.Default setting is for equaling.
Before the function of using the alarm merger, at first to clearly be how to judge identical alarm between NMS and the EMS.Can determine to judge the rule of identical alarm between NMS and the EMS by agreement or the mode of setting, that is:
A) the mode definite rule of judging identical alarm between NMS and EMS by arranging.At this moment EMS only need support the rule of the identical alarm of this judgement of arranging.Approximately regularly, can in exploitation NMS and EMS, just appoint, can not change and be in operation.
B) EMS also can support the rule of the identical alarm of multiple judgement simultaneously, and NMS sets the rule of the identical alarm of being adopted of judgement to EMS by northbound interface.When NMS did not set, EMS got the rule of a default identical alarm of judgement, promptly was equal to above-mentioned stipulated form this moment.
Adopt agreement or the mode of setting no matter be, if what adopt is the judgement that (3) rule of planting the identical alarm of judgement of mode is carried out identical alarm, promptly judge by one group of attribute contrast condition of flexible setting, then must provide NMS by the function of northbound interface, comprise the increase of attribute contrast condition and deletion etc. at least to EMS management " attribute contrast condition ".
In second step, NMS manages the alarm merger rule that EMS goes up configuration by northbound interface.
Described alarm merger rule is used to judge whether an alarm needs merger.Can dispose many alarm merger rules on EMS simultaneously, expression is carried out merger to a few class alarms simultaneously.Generally define concrete alarm merger rule by setting attributes such as alarm type, alarm source.For example:
Alarm code=xxxx, subnet number=xxxx, network element number=xxxx can be set on EMS, and pre-conditioned if the alarm code of the i.e. a certain alarm of expression, subnet number, network element number meet, this alarm need be alarmed merger so.
If a certain alarm has met above-mentioned merger rule, also not identical with it simultaneously alert existence of report, it is alert that then this alarm is report.
NMS mainly is that configuration increases alarm merger rule on EMS to the management of alarm merger rule, or deletion alarm merger rule, perhaps existing certain bar alarm merger rule is made amendment.Therefore, NMS need have at least to the increase of alarm merger rule, the function of deletion.Wherein, the function of described modification is not necessarily necessary, and modification can realize by deleting to increase again.
The 3rd step, the processing (as shown in Figure 1) of EMS when NMS sends alarm information
Need on NMS, give the correct time when EMS has alarm, utilize each alarm merger rule to differentiate this alarm successively, judge whether this alarm needs merger (step 101～104);
If this alarm does not need merger, then directly send this alarm (step 105) to NMS;
If need merger, judge further then whether the report police of such alarm is empty (step 106);
The police is empty as report, and then this alarm is set to the report police, preserves the report police and will alarm the generation number to be changed to 1 (step 107), sends this alarm (step 105) to NMS;
The police is not empty as report, will alarm the generation number and add 1 (step 108), process ends.
Wherein, describedly need be meant to giving the correct time on the NMS when EMS has alarm: after EMS receives alarm, if NMS has ordered this alarm to it, then EMS just need report to NMS.
The 4th step, the processing (as shown in Figure 2) of EMS when NMS sends alarm recovery message
When alarm clearing arrives, utilize each alarm merger rule successively this alarm clearing to be differentiated, judge whether the alarm of this alarm clearing correspondence meets an alarm merger rule (step 201～204):
If do not meet, then send this recovery (step 205) to NMS;
If meet, judge further then whether this alarm clearing is the alert recovery of report (promptly first the recovery) (step 206): if first the recovery, then this alarm clearing is changed to first recovery and preserves this head recovery (step 207), to alarm the generation number simultaneously and subtract 1 (step 208), if not first the recovery then will be alarmed the generation number and be subtracted 1 (step 208).Then, judge that alarm takes place whether number is 0 (step 209),, then finish if be not 0, if 0, then send first the recovery, with report police deletion (step 210) from preserve to NMS.
Wherein, when alarm clearing arrives, look for the corresponding alarm of this recoverys earlier, and then the alarm of seeing correspondence match-merge rule whether, as long as there have a rule to meet to be just passable.If do not meet entirely, then do not deal with.
Above alarming processing in described the 3rd step and the alarm clearing in the 4th step to handle be generations that can walk abreast, not necessarily before and after generation successively.
Described embodiment can further include additional treatment step, that is:
NMS is when receiving that report is alert, if display alarm information on the interface, then can carry out conversion process to warning information as required, be shown as an information comprehensive, that comprised alarm merger information, thereby make administrative staff understand the situation of alarm merger more easily.
For the method for the different identical alarms of judgement, content displayed may be different.Mainly show below information: a) tell administrative staff that this is a warning information after the merger; B) merger which alarm, this is relevant with method of judging identical alarm.For example, actually show the alarm that this alarm alarm code is identical, Hai Shi the identical alarm of several attribute.Certainly, also can based on method of the present invention, show that the relevant information that needs is to administrative staff according to the needs of practical situations.
