Description
Technical field
The present invention relates to network management, be specifically related to the method for acquiring real-time performance data by network manager.
Background technology
NMS normally is made up of webmaster and the network element device managed thereof, through the NMP interactive maintenance information of agreement, like snmp protocol, accomplishes various management functions between the two.ISO has defined five big basic functions of network management in the ISO/IEC7498-4 document, and is widely accepted.This five big basic function is: (1) fault management (fault management), (2) accounting management (accounting management), (3) configuration management (configuration management), (4) performance management (performance management) and (5) safety management (securi tymanagement).Wherein performance management is had important function in assessment by aspects such as the operation conditions of guard system and operational efficiency.Through to analyze from the performance data of being collected by guard system with relatively; Can understand current by the running status of guard system; In time discover the abnormal conditions that occur when being moved, find that by the operating bottleneck of guard system, prediction is by the operation trend of guard system by guard system; Take appropriate measures and solve or prevent the fault that possibly occur thereby help administrative staff, perhaps through reconfiguring by the resource in the guard system to keep by the runnability of guard system.So accurately and reliably whether the performance data that network management system is collected, and will have influence on administrative staff's analysis, judge, and the validity of the measure of taking.
The particular content of performance management function comprises: the management of the collection of the collection of real-time performance data and management, History Performance Data and management, performance threshold, the analysis of performance data and visual report etc.In the webmaster practice, what History Performance Data reflected is long-term performance data situation of change, will preserve the above time of some months usually.The common History Performance Data that 15 minutes intervals are arranged, and 24 hours History Performance Datas at interval.Because its time interval is long, is generally used for the long-term monitoring of systematic function, trend analysis.And real-time performance data reflections is performance data situation of change in a short time, and particularly current performance data situation need not preserved for a long time.The common time interval has 10 seconds, and 20 seconds, 30 seconds etc.Compare with the historical performance management, the reflection that real-time performance management more can be meticulous is by the situation of change of the performance data of guard system in a period of time recently.
The common methods of real-time performance monitoring is; The network management system that network management system realizes based on the mode of poll is to by the collection of the real-time performance data of guard system; Be network management system at a certain time interval, send by the query requests of correlated performance data in the guard system.Need the real-time performance parameter (such as speed etc.) of calculating mean value for some, network management system is through the difference of the original performance data that twice collects before and after calculating, and obtains divided by the time interval between twice collection.After obtaining these real-time performance data, network management system is with the patterned mode real-time performance curve that draws.
There is following problem in this mode:
1, can cause the losing of performance data of a poll time point of network management system, thereby cause two poll time points (this and next time) can't calculate through the performance parameter that the original performance data are calculated.
2: complicated large-scale by guard system for some, network management system is with certain polling interval, to the query requests of being sent performance data by guard system.And handle and reply time request each time by the processing delay of guard system collecting performance data and network delay, have nothing in common with each other.Special; For some by multistage managed object form by guard system, its subordinate's managed object itself can not be calculated and the handling property data, calculates and handles in higher level's object and collected with the mode of poll by higher level's managed object; In general; Be difficult to be consistent between the poll time point of the poll time point of guard system self and network management system, therefore be easy to cause network management system collection and the performance data of calculating, bigger error occurred with actual conditions.For example, network management system in twice adjacent data collection activity of network management system, might obtain identical performance number to the same performance parameter of same managed object.Thereby make the calculating of the performance number of one type of similar speed, very big error occurs.
Cause the basic reason of these problems to be 1: the acquisition time point of real-time performance data is that the poll time point by network management system decides.And the poll time point of network management system is that network management system produces at random, is difficult to synchronous by the inner poll collection activity of guard system, thereby causes the inaccurate of original performance data.2: network management system is initiated the collection activity of real-time performance data at random, and webmaster is based on the original performance data that obtain, through calculating the value of other performance parameter.Thereby the performance parameter value that causes these to calculate is inaccurate.
