The example of the consistent system and method for some aspects be described in detail in claims, the application.
Fig. 1 is a kind of structural schematic diagram of CDN quality of service monitoring system shown according to an exemplary embodiment.
As shown in Figure 1, including: the present embodiment provides system
Edge device 11 collects CDN service state index data for providing CDN service for netizen, and by the service
State index data are stored into shared drive, and report the service state achievement data；
Central server cluster 12, the service state index number reported for receiving and storing the edge device
According to, and api interface is provided and carries out quality monitoring using the service state achievement data for operation maintenance personnel.
For example, front end refers to according to service state after operation maintenance personnel obtains service state achievement data by using api interface
Mark data draw table perhaps the operation maintenance personnel such as line chart by seeing that table or line chart can more intuitive monitoring service matter
Amount.
Particularly, shared drive is a kind of technology of shared same region of memory of multiple processes, passes through system specified
It calls and creates one piece of continuous linear address space in memory, and this block memory can also be discharged by system calling.One
As, an edge device can receive multiple parallel request task processes, and the data that multiple processes are transmitted are stored to shared
It is faster quicker to disk storage than landing in memory, data statistics writing range is expanded, data acquisition week is shortened
Phase acquired hundred rank of item, after new method, data for example, the use of disk storage data acquisition intervals being originally one hour
Acquisition interval is one minute, reduces overall calculation resource burden.
In the present embodiment, since edge device provides CDN service for netizen, that is, the various service requests of netizen are received, with
And CDN service state index data are collected, and service state achievement data is stored in shared drive, and service state is referred to
Mark data are reported to central server cluster, and central server cluster counts these after receiving these service state achievement datas
According to carrying out landing storage, and api interface is provided and carries out quality monitoring using the service state achievement data for operation maintenance personnel.Such as
This shortens data collection cycle using shared drive storage service state index data augmentation data statistics writing range,
So that service state achievement data is more comprehensively, operation maintenance personnel is more sensitive to the perception of service equipment service condition, according to more comprehensively
Service state achievement data can preferably monitor the service equipment service condition in CDN system, to improve service effectiveness.
Fig. 2 is a kind of structural schematic diagram of the CDN quality of service monitoring system shown according to another exemplary embodiment.
As shown in Fig. 2, system provided in this embodiment includes:

Further, the statistical server carries out parallelization operation to the service state achievement data.
Further, the deployment services device is for detecting the dispatch server, the storage server and the system
Count the operation conditions of server.
Wherein, there is the logic generation for being responsible for collecting CDN service state index data during the logical process in service unit
Code, provides resource service after service unit receives the request of netizen for netizen, then by the related service number of each request
It is collected according to (i.e. CDN service state index data).Service unit is interacted by relevant interface with shared internal storage location, by phase
Business datum storage is closed into shared drive unit.
It should be noted that service unit is asynchronous unplugged multiple progress structure, i.e., service unit is multiple, Ke Yijie
Receive multiple independent process, the data of multiple independent process are stored in shared drive read for reporting unit after to server set
Group reports.
It is understood that statistical module can be added in the flow chart of data processing of service unit, which can match
The data item acquired needed for setting, data acquisition item can be, but not limited to include that request time, integrated flow, instant bandwidth, CPU are born
Load and I/O load etc..
Reporting unit reading service state index data and is reported to center from shared drive according to report cycle, periodically
Server cluster, report cycle can be by related personnel's self-settinies, for example, reading and reporting primary every 10 hours.On in addition,
Declaration form member has the function of that period timing is upset, though timing, which is upset, refers to that distinct device has identical data report cycle, in the period
Interior data report time point different, concurrently report this avoid same time point data and cause central server cluster
Periodical high load the phenomenon that.
Dispatch server includes scheduling unit, after the service state achievement data received, according to deployment services device pair
The monitored results of the operating status of storage server cluster select optimal storage server to carry out data storage, actively with true

The data for carrying detection carry out elastic adjustment to storage server and statistical server, in the case where ensuring service invariant operation
Reduce cost.
In the present embodiment, not only by using the data statistics write-in of shared drive storage service state index data augmentation
Range shortens data collection cycle, so that service state achievement data is more comprehensively, operation maintenance personnel is to service equipment service condition
Perception it is more sensitive, the service equipment industry in CDN system can be preferably monitored according to more fully service state achievement data
Business state, and then realized the effect improved service quality.Further, also pass through design dispatch server, storage clothes
Be engaged in device, statistical server and deployment services device, improve system reliability, it is ensured that monitoring system it is perfect, ensure that industry
The immediate feedback for service quality of being engaged in reduces traffic failure feedback bring risk not in time to improve customer perception.
The application in order to better understand below explains the realization mechanism of shared drive unit storing data.
Shared drive is the most basic inter-process communication methods provided under Linux, it is invoked at by system specified
One piece of continuous linear address space is created in memory, and this block memory can also be discharged by system calling.Using altogether
The benefit for enjoying memory is to have modified in shared drive when multiple processes are using same shared drive in any one process
After content, other processes can access modified content by accessing this section of shared drive.
For example, as shown in figure 3, process 1, process 1 and these three independent process of process 3 receive the business of three concurrent processes
Data, these parallel business datums store in the shared drive created into memory modules.When process 1 has modified shared drive
In content after, process 2 and process 3 pass through this section of shared drive of access also available modified content.Also, it is multiple only
Vertical process operates shared drive unit using spin lock, realizes one of the service state achievement data in shared drive
Cause property.
In the present embodiment, the resource request from netizen is divided into multiple stages, needed for each stage has respectively
The important indicator of statistics, and the statistical indicator of the different requests of multiple concurrent processes is needed toward the same shared drive in the same time
In deposit and write data, the spin lock by completing atomic operation solves the problems, such as data consistency in shared drive.
