It calculates, obtains STA process data, the regular judgement of process data progress and statistics are calculated, obtains in wlan network and occurs on a large scale
Relevant information is stored in the MySql database in data-base cluster, for operation management with this positioning failure by the object of STA failure
System is shown and fault warning.
Wherein, in MapReduce Computational frame, map and reduce function is being executed for task, by master entity
Assign tasks to the execution of worker entity.Map function reads assigned input data segment, exports middle k ey/value
The set of pair value, reduce function collect the value value with identical middle k ey value, merge these value values, form one
The set of a lesser value value.
In embodiments of the present invention, the step of the step of data collection and fault diagnosis position can be mutually indepedent.Wherein
The step of data collection, is as follows:
Step A, operation management system obtains n wireless access point AP respective the first operation day in the period 1
Will, and, it obtains the respective third running log in the period 1 of STA in WLAN and is specifically passed through by AP
Send the first running log to operation management system on Syslog standard agreement UDP, alternatively, AP is by calling Rest interface to O&M
Management system sends STA log, and (i.e. third running log, may include downtime on STA, and the SSID information of access uses
Situations such as flow).
Step B, all first running logs are summarized for the second running log, and, all third running logs are summarized
For the 4th running log, i.e., the data acquired in step 1 are saved into Elasticsearch database.Usual operation management system
System can check Syslog data information in Elasticsearch database and do some basic statistics.Operation management system
Incremental data in Elasticsearch is saved in HDFS file system automatically per hour by system timing.
Data acquisition on the basis of, fault diagnosis position the step of it is specific as follows:
Step 1: timing obtains newest one hour Syslog incremental data file from data-base cluster.
Major key is identified as with the wireless terminal STA in second running log Step 2: generating, with the major key
The life of the content and running log corresponding with the major key of the mark of corresponding AP and the corresponding running log of the major key
It is the record of content at timestamp.
It is operated specifically, Mapreduce can be carried out to Syslog data file by diagnostic service unit:
In the Mapper stage, filter out there are staMac (MAC Address of STA, for STA mark one kind) data field report
Text, using staMac as major key, with AP identify (such as: equipment Serial Number SN code), Syslog message content and Syslog generation when
Between stab merging content be numerical value, generate Mapper record.
In the Reducer stage, classify Mapper data using staMac as dictionary major key, under each staMac major key again with
AP equipment SN code is dictionary major key classification Syslog content, to identical staMac, when Syslog is pressed in the data grouping of identical SN code
Between stab and be ranked up.
All Syslog under each SN code word allusion quotation are matched to judge type of message, judge to be message identifying,
It is associated with message, IP assignment message, IP switches message or the offline message of STA, and is associated with out STA owning at this AP with this
STA process, each STA process include (staMac, SN the code AP of STA connection (possessed identifies), authenticated time, when association
Between, IP is distributed the time, STA on-line time, STA downtime, STA current state (mark success or failure)).
Step 3: above-mentioned STA process is associated with the flow information in STA log, during matching relationship is STA
SN code, on-line time, the SN code in downtime, with STA log, on-line time, downtime is consistent, then in STA process
Increase corresponding SSID name and flow information in STA log in dictionary.
It is carried out respectively by staMac, SN, SSID Step 4: the STA process data after being associated with STA log copies three parts
Grouping, each grouping are ranked up by the authenticated time of STA process again.
Step 5: calculating the staMac grouping information in step 4, statistics calculates continuously to be gone out in all 10 minutes
The STA process of existing STA state failure, the failure of access terminal itself is then considered if there is individual staMac failed points, such as
Fruit is all staMac while going wrong, and is considered that whole network breaks down.
Step 6: calculating the SN code grouping information in step 4, continuously there is STA shape in all 10 minutes in statistics
The STA process of state failure is then considered that the AP breaks down if there is individual SN failed points, and concrete reason can call
Syslog failure content is presented.
Step 7: calculating the SSID grouping information in step 4, continuously there is STA shape in all 10 minutes in statistics
The STA process of state failure is then considered that the SSID breaks down if there is individual SSID failed points, and concrete reason calls
Syslog failure content is presented.
Step 8: device log diagnostic result is written in relevant database MySql.
Step 9: operation management system timing detects that there are new network failures from MySql database, just to O&M
Personnel send alarm.
Step 10: operation maintenance personnel can check the fault point that network occurs in operation management system, and pass through Syslog
Content carries out specific aim solution.
The beneficial effect of the embodiment of the present invention is that full-automatic all-weather acquires all AP equipment under wlan network
System log and STA log, find the network failure in WLAN automatically in the case where unattended, and from trend O&M people
Member sends a warning message, and reaches wlan network full-automation fault discovery and positioning.And using the analysis statistics side of big data
Method, many and diverse data such as system log, STA log by it is associated with practical business process and polymerization calculation method,
It is combined with application scenarios, effectively increases the accuracy of failure predication result, also improve availability.
