Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The CDN is mainly used for relieving congestion of a backbone network and accelerating the access speed of a user. The principle is that CDN edge nodes are utilized to cache resources of a remote source station to the local so as to accelerate the access speed of a user to the resources. If the resources accessed by the user are not found in the CDN edge node, the edge node can return the source to request the resources from the source station, the resources retrieved from the source station are sent to the user and are locally stored in the edge node, and when other users request the same resources, the resources are directly retrieved from the local and returned to the user.
In order to ensure the quality of the CDN service, the operation indexes of each service of the cache node need to be monitored, so that the problem of service index acquisition is involved. The service indexes of each running service process on one device are easy to collect, and only one collection script needs to be deployed on the device and is regularly executed for collection. However, sometimes, a service index at a node level needs to be concerned, and the purpose cannot be achieved by using a collection method for single equipment.
Currently, a single device is generally collected first, and then the collected data is uploaded to a central server, which classifies and summarizes the data according to nodes. However, the disadvantages of this approach are evident: the edge nodes have a lot of devices, so that the bandwidth occupation of the central server node is large (the bandwidth cost of the central server node is generally large); and handling the upload requests of a large number of edge node devices also puts a heavy strain on the central server.
In order to solve the technical problem that the bandwidth of the central server is occupied greatly because each device in the node respectively sends the service index data to the central server, the present application provides a method, an apparatus, a device and a system for acquiring service index data applied to the CDN, and the following description is provided in an embodiment.
Example one
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a method for acquiring service index data applied to a CDN according to an embodiment of the present disclosure. In this embodiment, the interaction between the collection device in the node, the other devices except the collection device in the node, and the central server is taken as an example for explanation.
As shown in fig. 1, the method for acquiring service index data applied to the CDN provided in this embodiment includes:
It should be noted that the priority list is preset, and the priority list may include an order of priorities of devices in the node and device identifiers of the devices in the node, where the device identifiers may be codes compiled in advance for the devices, or may be IP addresses of the devices in the network, as long as the device identifiers can be addressed to the devices. For example, there are A, B, C three devices in the node, and the priority order of each device agreed in the priority list is, from high to low, an a device, a B device, and a C device, where the device identifier takes the IP address of each device as an example, the IP address of the a device is 192.168.21.1, the IP address of the B device is 192.168.21.2, and the IP address of the C device is 192.168.21.3, then the priority list may be as shown in table 1, where priority 1 is the highest in table 1, and the larger the number is, the lower the priority is.
| Device name | Priority level | Equipment label (IP address) |
| A equipment | 1 | 192.168.21.1 |
| B device | 2 | 192.168.21.2 |
| C equipment | 3 | 192.168.21.3 |
TABLE 1
And 102, each device in the node judges the priority of the device in the node.
Taking the above device a, device B, and device C as examples, the device a determines that its own priority is the first bit, the device B determines that its own priority is the second bit, and the device C determines that its own priority is the third bit.
And 103, determining the acquisition equipment to be equipment for acquiring all equipment service index data in the node according to a preset convention by the acquisition equipment.
And step 104, determining that the other equipment except the acquisition equipment in the node is equipment which does not acquire service index data of all equipment in the node according to a preset convention.
It should be noted that the preset convention may be that the active device with the highest priority is a device that collects service index data of all devices in the node, that is, a collection device, and the other devices are devices that do not collect service index data of all devices in the node, that is, other devices. The active device may be a device in a node in an operating state, where the operating state referred to herein may refer to a power-on state, or may refer to a power-on state without a fault. Taking the above-mentioned device a, device B, and device C as an example, since the priority order is device a, device B, and device C in sequence, when all three devices are active devices, device a is an acquisition device, and device B and device C are other devices; when only the device B and the device C are active devices, the device B is a collecting device, and the device A and the device C are other devices.
And 105, sending a service index data acquisition request to all the equipment in the node by the acquisition equipment.
And 106, each device receives a service index data acquisition request.
And step 107, each device sends respective service index data to the acquisition device according to the service index data acquisition request.
When each device transmits the service index data, the device identifier of the device can be associated with the service index data of the device, and then the service index data is transmitted. It should be noted that each device includes an acquisition device and other devices in the node except the acquisition device.
And step 108, receiving the service index data of each device by the acquisition device.
And step 109, integrating the acquired service index data of other equipment and the acquired service index data of the acquisition equipment by the acquisition equipment to obtain node-level service index data.
The integration processing in this step may be a processing method of summarizing the service index data sent by each device according to the device identifier of each other device. This step may relieve the central server from the pressure of processing the data. Of course, the collection device may directly send the service index data of each other device to the central server without performing integration processing.
And step 110, the acquisition equipment sends the node-level service index data to a central server.
Firstly, a collection device in a node sends service index data acquisition requests to all devices in the node, each device returns service index data to the collection device according to the received service index acquisition requests, and the collection device sends the service index data to a central server in the CDN system after receiving the service index data of each device. Based on the method, each device in the node is prevented from respectively sending the service index data of the device to the central server, the bandwidth of the central server is saved, and the bandwidth cost of the central server is reduced.
Example two
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a service index data acquisition method applied to a CDN according to a second embodiment of the present disclosure. The present embodiment takes the execution on the acquisition device side as an example for explanation.
As shown in fig. 2, the method for acquiring service index data applied to the CDN provided in this embodiment includes:
And step 22, receiving service index data.
And step 23, sending the service index data to a central server of the CDN system.
Firstly, a collection device in a node sends service index data acquisition requests to all devices in the node, each device returns service index data to the collection device according to the received service index acquisition requests, and the collection device sends the service index data to a central server in the CDN system after receiving the service index data of each device. Based on the method, each device in the node is prevented from respectively sending the service index data of the device to the central server, the bandwidth of the central server is saved, and the bandwidth cost of the central server is reduced.
It should be noted that, for the specific explanation of the above steps in this embodiment, reference may be made to the first embodiment of the present application, which is not described again in this embodiment.
Further, the selection of the collection device may be performed in various manners, for example, the collection device may be directly designated, and one device in the node is directly designated as the collection device at an initial operation stage to collect the service index data of all devices in the node, however, the manner loses the capability of collecting the service index data when the designated collection device is damaged due to a fault, and is poor in stability, so that another manner may be provided, for example, the current collection device is automatically generated by a selection manner according to priority, and the specific steps of the manner are as follows:
first, before being elected as an acquisition device, the acquisition device of this embodiment acquires a priority list of each device in a node, and then determines its own priority according to the priority list, and elects itself as the acquisition device when it is a device with the highest priority among node active devices, and certainly, if there is an active device with a higher priority than its own priority in a node, it cannot be elected as the acquisition device and is converted into another device in the node.
For the detailed explanation of each term or step in the above steps, reference may be made to the first embodiment of the present application, which is not described herein again.
In addition, in order to reduce the pressure of the central server on processing data, the collecting device may process the service index data of each other device before sending the service index data to the central server, and therefore, step 23 may include:
integrating the service index data of other equipment and the service index data of the acquisition equipment to obtain node-level service index data; and sending the node-level service index data to a central server of the CDN system.
Specifically, the detailed explanation of each term or step in the above steps can refer to the first embodiment of the present application, and is not repeated herein.
