Description
Technical field
The present invention relates to quality of data automatic monitoring technical field, particularly a kind of quality of data of operation maintenance center of the maintenance centre northbound interface that can configure method of monitoring automatically.
Background technology
Along with the development of operator's full-service operation, network size constantly expands, and network configuration is day by day complicated.Especially bringing of 4G epoch, need to include LTE equipment in webmaster, meet the Network Management and Maintenance demand of LTE network, when LTE networking completes, webmaster can provide perfect O&M supporting method, the complexity of network is safeguarded and has been proposed new requirement network management, for the data Layer of bottom, no longer require to realize all management application at this layer, but emphasize more the availability of interface and data.In maintenance process, because of LTE equipment networking Applicative time not long, especially operation maintenance center of OMC(maintenance centre) northbound interface is also unstable, often find that data are imperfect, problem not in time, the requirement that the north direction interface data quality of entirety does not reach webmaster, and often cannot carry out positioning problems, cause the availability of network management system to decline, if network management data is of low quality, cause confidence level to decline, traffic affecting management.
The importance of the quality of data is not second to business function, and the quality of data is the important leverage that business runs well.Whether O&M personnel often query the data that obtain from network management system complete, accurate, credible, finally affect service fulfillment efficiency, as resource data inaccuracy, upgrade not in time, cause equipment or port information can not truly reflect current service condition, have a strong impact on opening and using of business.
Data quality management need to be served as daily work, just as service system is processed business every day, carry out the routine work of data management every day, therefore need to set up a closed loop management mechanism, find in time, analyze, revise data, promote the availability of whole data, build one automatically, the quality of data monitoring system of closed loop is imperative.
The at present monitoring of the quality of data is mainly by mode artificial or that combine with part IT means, but in default of a complete monitoring system and method, monitors at present efficiency and effect all undesirable.
Therefore need to promote monitoring by an automated method and promote the quality of data, and give full play to the value that data produce, promote service ability, reduce O&M cost, guarantee Cybersecurity Operation, for business development provides strong support.
Summary of the invention
For evade monitoring dimension not, analysis depth and the inadequate problem of range, the mode of the present invention from adopting multiple dimensions to monitor one by one, in conjunction with the O&M experience of safeguarding to OMC northbound interface and the requirement of the quality of data of network management system to northbound interface for a long time, connectedness to northbound interface, promptness, integrality, validity are monitored in conjunction with the accuracy of index, set up active data quality monitoring mechanism, find by monitoring the problem that north direction interface data quality is potential, provide quality of data report timely comprehensively, the expansion of prevention and control error range.
The technical solution adopted in the present invention is as follows:
The quality of data of operation maintenance center of the maintenance centre northbound interface that can configure is a method for monitoring automatically, specifically comprises the following steps:
The connectedness monitoring of A, data-interface, the cycle sends packet to monitored interface, and interface is received rear timely return information, represents that Interface status is normal, records return time delay simultaneously and returns results;
B, the monitoring of data promptness, be that the promptness of northbound interface generation data report is checked, whether inspection north direction interface data source produces on request data, formed corresponding data report file;
The monitoring of C, data integrity, checks in north direction interface data report whether comprise network element and the data type that all configurations gather, and the network element number contrast that the network element number configuring in metadata management and existing network are collected, counts access ratio;
D, data validity monitoring, whether the data object that inspection northbound interface provides is effective;
E, data accuracy monitoring, for wireless parameter, performance data, measurement report parameter value, can carry out the interval setting of reasonability; For the data that exceed reasonability interval, provide abnormal early warning, reason in time notes abnormalities; For the value of key index in different inspection items, set the threshold value of corresponding index, threshold value definition has the upper limit, lower threshold definition; Index arranges multiple threshold intervals according to the different periods, to demonstrate different abnormal ranks;
F, the monitoring result of northbound interface is carried out to record, problem is classified; Form the quality of data report of northbound interface, formed quality of data knowledge base according to the processing summary of experience of the relevant data of collecting and Process Problems.
In steps A, the packet return time delay of transmission exceedes 5s without returning, and represents that interface is connective undesired at present.
In step B, the length that produces the cycle according to data claims to different cycles data delay, if the time delay that report produces is greater than the value of delay requirement and occurs data delay, the data report file time delay thresholding that configures Various types of data in metadata management, carries out early warning timely for the data that exceed time delay thresholding.
In step C, need to ensure the integrality of image data, enter filling mining flow process for the data that do not collect, require the first collection percentage of head rice of Various types of data to be at least 98%, after filling mining, reach 100%.
In step C, Integrity Verification not only checks for the integrality of network element number, the data type taking network element as unit in data report is verified the integrality of statistics network element data simultaneously, the first percentage of head rice of data that gathers network element is at least 95%, reaches 100% after filling mining.
In step D, whether the data object that inspection northbound interface provides effectively comprises following content:
A, file content comprise file header and file body two parts; File need to have the mark that significantly starts and finish;
Whether b, data object form meet standard-required;
Whether c, interface document and interface description document conform to;
Whether d, report file order of the field be consistent with standard;
Whether whether e, attribute field lack and record lacks;
Whether f, data value be within the scope of the codomain defining, and whether data format, type and business rule be consistent;
Carry out in time early warning for the data that do not meet validity rule, the first validity gathering of data at least will reach more than 99%, carries out filling mining again for invalid data, and after filling mining, data validity reaches 100%.
In step F, Question Classification is divided into following three classes:
The problem that a, monitoring generate;
The problem that b, assessment are found;
C, the manual problem of submitting to.
