Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
A first embodiment of the present invention relates to an apparatus state detection method, and the present embodiment is: acquiring node attributes of a detection target; the node attribute comprises the number of hosts of a node where a detection target is located; configuring a detection strategy of a detection target according to the node attribute and a preset detection rule; and sending a corresponding detection request to the detection target according to the detection strategy so that the detection target responds to the detection request and feeds back a detection result. The detection target is detected according to the nodes, different detection strategies are configured for the nodes with different host numbers, the problems that detection periods are too long and detection results are delayed greatly due to the fact that all devices are detected one by one are solved, and detection efficiency can be improved. The following describes implementation details of the device status detection method according to the present embodiment in detail, and the following is only provided for easy understanding and is not necessary for implementing the present embodiment.
As shown in fig. 1, the method for detecting a device state in this embodiment specifically includes:
Specifically, the CDN server setting mode is generally deployed according to nodes, each level is provided with a plurality of nodes, and each node may be provided with only one network server or a plurality of network servers. A plurality of servers are arranged in the same node, and the servers are communicated with each other and can perform mutual detection. During content delivery of the CDN, a target node with good link quality is determined first, and then a server with good performance is selected from the target node for task delivery. The traditional detection mode of the CDN is to detect all devices of all nodes in the same level one by one, summarize and compare detection results of all target devices, select a device with a better state to perform task allocation, and thus detect all devices one by one each time when content delivery is performed, and there are more devices detected in a round, resulting in a larger delay of the obtained result during summarization. In this embodiment, different detection modes can be set for different node attributes, and first, the node attribute of the detection target, that is, the number of servers in the node where the detection target is located, needs to be obtained. In this embodiment, the node attributes of the host are divided into a single host node and a multi-host node.
Specifically, a single host represents that only one device to be tested is arranged in a node, and a non-single host represents that a plurality of devices to be tested are arranged in the node. And configuring a detection strategy for the detection target according to the number of the hosts in the node, wherein different detection modes are configured for the single-host node and the multi-host node.
Specifically, when the node where the detection target is located is a single host node, the detection policy is to send a detection request to the detection target. The condition of only one device to be tested exists in the node, and in order to know the load condition of the node, the load condition of the node can be directly obtained from the only device to be tested of the node, so that the device state of the node can be quickly and effectively obtained.
And 104, performing mutual redundancy detection among a plurality of hosts included in the node where the detection target is located, generating a detection list comprising detection results of the hosts, and storing the detection list in the hosts in a distributed manner.
Specifically, when the node where the detection target is located includes multiple devices to be detected, each device in the node may detect other devices, store the detection results of the other devices and the detection result of the device in a detection list, store the detection list in a storage module of the device, and use the detection policy to obtain the detection list. Therefore, the detection results of all the devices in the node can be obtained by detecting any one device in the node, and the states of all the devices in the node can be directly judged. When the CDN scheduling node is determined, and then the equipment with good state is selected from the target node, the equipment with good state can be selected from the target node without waiting until all the equipment of all the nodes are detected one by one, so that the delay of obtaining the detection result is avoided.
Further, when the number of devices in a certain node is too large, even if the devices in the node perform mutual redundancy detection, the detection target of each device is more, and the detection result is delayed or exists, so that the devices in the node can be grouped to perform mutual redundancy detection in the group in order to reduce the time delay of the detection result; and selecting one device from each group, performing mutual redundancy detection among the groups, and acquiring a detection list of each group.
Specifically, since each device to be tested in the node stores a detection list of detection results of all devices to be tested in the node, detection results of all devices in the node can be obtained by detecting any one device. A device may be randomly selected from within the node to acquire.
Further, one host may be selected as the target host from a plurality of hosts in a polling manner. Specifically, performance indexes and load conditions of each device in the node are different, and downtime is caused when the load of the device is excessive or a fault occurs. If the selected target equipment is just down, the target host selected in a polling mode can be switched to another equipment in the next round, and the influence on detection is avoided when the equipment is down.
Further, query information may also be sent to multiple hosts; recording response time of each host responding to the inquiry information; and selecting the host with the shortest corresponding response time length from the hosts as the target host. In order to acquire the detection result more quickly, the target host can be selected through the speed of each host responding to the inquiry information, the detection result can be quickly acquired by selecting the device with the highest response speed to acquire the detection list, and the operation burden of the device with larger load is reduced.
Specifically, a detection list is directly obtained from the selected target host, and the detection list contains detection results of each device to be detected in the node, so that the detection results of each device in the node, including the detection result of the detection target, are obtained.
It should be noted that, in this embodiment, each device under test in the multi-host node performs mutual redundancy detection, in other embodiments, a device with an optimal performance index in the multi-host node may also be designated as a target host, the target host is responsible for detecting device states of all devices under test in the node, and stores a detection result in the target host in a list form, and the detection result of the entire multi-host node is obtained from the target host during detection, so that resource occupation of each device in the entire node can be reduced.
Further, in this embodiment, different detection policies are configured according to the node attribute classification manner of the single host node and the multi-host node, and in other embodiments, the detection policies may also be configured according to other attributes of the nodes. For example, whether load balancing is performed in a node, whether a dedicated scheduling host is set in a node, or whether a task allocation manner is governed by time in a node, and the like, which is not limited in this embodiment.
According to the embodiment of the invention, different detection strategies are configured according to the node attributes of the detection target, and different detection strategies are configured for the nodes with different host numbers, so that the detection result of the target equipment can be quickly obtained, the problems of overlong detection period and large detection result delay caused by the fact that all equipment is detected by the same method are avoided, and the detection efficiency can be improved.
A second embodiment of the present invention relates to an apparatus state detection method. The second embodiment is substantially the same as the first embodiment, and mainly differs therefrom in that: in the second embodiment, in consideration of the case where a load balancing device may be provided in a node including a plurality of hosts, the load of each device is the same in the node including the load balancing device.
As shown in fig. 2, the method for detecting a device state in this embodiment specifically includes:
Those skilled in the art can understand that, for the load balancing device, the load capacity of each device in the node is the same, and the load condition of each device in the node can be obtained only by detecting the load balancing device, so that the detection result can be obtained more quickly.
According to the embodiment of the invention, different detection strategies are configured according to the node attributes of the detection target, and different detection strategies are configured for different nodes, so that the detection result of the target equipment can be quickly obtained, the problems of overlong detection period and larger detection result delay caused by the fact that all equipment is detected by the same method are avoided, and the detection efficiency can be improved.
A third embodiment of the present invention relates to an apparatus state detection method. The third embodiment is substantially the same as the second embodiment, and mainly differs in that: in the third embodiment, a plurality of detection targets are detected, the comprehensive state of the equipment is evaluated according to the detection result, and then the equipment with a better state is selected for task configuration. As can be understood by those skilled in the art, in CDN content delivery, a server with a good load condition needs to be selected for content delivery.
As shown in fig. 3, the method for detecting a device state in this embodiment specifically includes:
301, acquiring node attributes of a plurality of detection targets; the node attribute comprises the host number of the node where the detection target is located.
In the present embodiment, the content of steps 301 to 303 may be detected by using the device state detection methods provided in the first and second embodiments, where the method configures a corresponding detection policy according to a node attribute of a detection target, and detects the plurality of detection targets, and the specific detection policy is not described again.
And step 304, evaluating the equipment state of the detection target according to the state parameters in the detection result.
Specifically, the detection result includes a state parameter of the detection target; wherein, the state parameter includes one or any combination of the following: CPU parameter, memory parameter, disk parameter, bandwidth parameter, service program running state and interface access delay state; and evaluating the equipment state of the detection target according to the state parameter. In practical applications, the detection server may only detect the state parameters of each detection target, and an evaluation needs to be performed on the state parameters of the detection targets to obtain the comprehensive state of the detection targets, so as to compare the states of the devices. The device state checking method is suitable for checking the device state of the target device to be scheduled during CDN content distribution, detecting the device state in real time after responding to a user request, and selecting the device with good load condition for content distribution.
In one example, the state parameters include all the above parameters, i.e., CPU parameters, memory parameters, disk parameters, bandwidth parameters, service program running state, and interface access delay state; the device status may be scored according to the following formula:
device state score value (cpu × a + memory × b + io × c + timeout × d + bandwith × e) × l/x + f
Wherein a, b, c, d, e are weighting coefficients, x is a division factor, which can be set according to actual conditions, and the embodiment is not limited; l is link quality, f is service program running state, CPU, memory, io, timeout, and bandwith represent CPU parameter, memory parameter, disk parameter, interface access delay state, and bandwidth parameter, respectively. The scoring mode considers the link quality and the running state of the server, and a better scheduling path can be selected through the scoring mode. In other embodiments, the device status may also be evaluated in different status parameter setting manners or different device status scoring manners, which is not limited in this embodiment.
And 305, selecting a detection target with equipment state meeting specific conditions from preset detection targets according to detection results of a plurality of detection targets, and performing task configuration.
Specifically, when performing task allocation, in order to select the device with the best status to complete the task, so as to enable the task to be completed efficiently and quickly, after the device status detection method in the present embodiment is used to detect and evaluate a plurality of target devices, a device with the best status is selected from the plurality of devices to allocate the task. For example, in a CDN content delivery scenario, when a resource acquisition request sent by a terminal is received, a scheduling server may select a group of scheduling target lists meeting conditions according to a predetermined scheduling rule according to an IP address of a request terminal, as shown in fig. 4, according to the device status detection method provided in this embodiment, the scheduling server generates a detection policy according to each scheduling target, that is, a node attribute of the detection target and a preset detection rule, and directly detects a device in a single host node; for a multi-host node, mutual redundancy detection is carried out on each device in the node to generate a detection list comprising detection results of each device, and the detection results of each device in the node are obtained from any one device or load balancing device. And finally, according to the detection result. And selecting one device with the optimal load condition from all the devices to be selected as a scheduling target.
Further, the scheduling targets screened in advance may be sorted according to a certain priority, for example, sorted according to a sequence from a near to a far from the target IP address, and finally, the scheduling target list is traversed according to the priority sequence, so as to comprehensively consider the scheduling targets with the highest priority and the device load status meeting the condition.
According to the embodiment of the invention, different detection strategies are configured according to the node attributes of a plurality of detection targets, so that the detection results of a plurality of target devices can be rapidly obtained, and the devices with states meeting specific conditions are selected for task allocation according to the detection results of the plurality of detection targets. The method can quickly and accurately obtain the detection result, avoids detecting all the devices one by one, and improves the efficiency of task allocation, and the detection period is too long, and the detection result is delayed greatly.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
