Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 shows a flow diagram of a method of monitoring a network node according to an embodiment of the invention. As shown in fig. 1, the method includes:
step S110: respectively sending the monitoring tasks corresponding to the network nodes to a plurality of monitoring nodes respectively connected with the network nodes so that each monitoring node can respectively send the monitoring tasks to the network nodes; the monitoring task comprises monitoring period information.
Specifically, in this embodiment, in order to improve monitoring accuracy, a plurality of monitoring nodes respectively connected to the network node are provided for the same network node. Each monitoring node monitors independently, so that result deviation caused by inaccurate results of one monitoring node is prevented.
In addition, the monitoring task further comprises monitoring period information, wherein the monitoring period information is used for indicating the network node to complete periodical feedback so as to prevent inaccurate phenomena caused by network jitter on the feedback value at a single time point. The method execution body in this embodiment may be a network device such as a central control server, and the network node to be monitored may be various nodes such as a DNS node, a cache node, and an HTTP server node.
Step S120: respectively acquiring node monitoring values, corresponding to monitoring tasks, of the network nodes reported by all the monitoring nodes; the node monitoring value of the network node corresponding to the monitoring task reported by each monitoring node is determined according to a plurality of periodic monitoring values corresponding to the monitoring period information contained in the monitoring task and returned by the network node.
Each monitoring node independently acquires a node monitoring value reported to the monitoring node by the network node. The node monitoring value is used for indicating a monitoring value of the network node monitored by the monitoring node. Specifically, in order to prevent the influence of network jitter, the network node needs to generate a plurality of periodic monitoring values corresponding to the monitoring period information for the monitoring task issued by each monitoring node. Each periodic monitoring value corresponds to a monitoring value in a time period, and the node monitoring value of the network node in a period of time can be accurately estimated through the periodic monitoring values corresponding to a plurality of periods.
Step S130: and determining the monitoring result of the network node corresponding to the monitoring task according to the node monitoring value of the network node corresponding to the monitoring task, which is reported by each monitoring node.
Specifically, each monitoring node reports the node monitoring values of the network node corresponding to the monitoring tasks, which are acquired by the node, so that the number of the node monitoring values is multiple, and the monitoring results of the network node corresponding to the monitoring tasks are determined by integrating the multiple node monitoring values, thereby remarkably improving the monitoring accuracy. The value range of the node monitoring value can be flexibly set according to the actual service scene. Correspondingly, when the monitoring results of the network node corresponding to the monitoring task are determined by integrating the plurality of node monitoring values, the value range of the node monitoring values and the actual service scene can be flexibly processed, and the invention is not limited to the above.
Therefore, in the network node monitoring method disclosed by the invention, on one hand, the same monitoring task aiming at the same network node can be respectively sent to a plurality of monitoring nodes, the plurality of monitoring nodes monitor in parallel, and the monitoring data of the plurality of monitoring nodes are synthesized to determine the final result, so that the monitoring accuracy is improved. On the other hand, each monitoring node can acquire a plurality of periodic monitoring values corresponding to a plurality of periods of the network node respectively, and the node monitoring values corresponding to the monitoring node of the network node are determined by integrating the plurality of periodic monitoring values, so that inaccurate results caused by abnormal factors such as network jitter and the like are prevented. Therefore, the accuracy of the monitoring result can be greatly improved, and the interference of external factors can be prevented.
Fig. 2 shows a flow chart of a method for monitoring a network node according to another embodiment of the invention. In the present embodiment, the network node monitoring in the content delivery network (Content Delivery Network, CDN) system is exemplified. The network nodes to be monitored may be (Domain Name System, DNS) domain name system nodes in the CDN system, hypertext transfer protocol (HyperText Transfer Protocol, HTTP) server nodes and/or cache nodes, etc. In this embodiment, in order to facilitate the implementation of the monitoring function, the CDN system specifically includes: the system comprises a central control server, a WEB server (website server), a monitoring database and a plurality of monitoring nodes. The WEB server and the central control server are respectively connected with the monitoring database, and the central control server is further connected with a plurality of monitoring nodes. The WEB server is used for dynamically configuring the monitoring tasks to be executed in the monitoring database according to actual demands, and the central control server is used for dynamically reading the configured monitoring tasks to be executed in the monitoring database and distributing the monitoring tasks to a plurality of monitoring nodes so that each monitoring node can respectively distribute the monitoring tasks to corresponding network nodes. In addition, in this embodiment, the plurality of monitoring nodes are simultaneously connected to one network node, so that the plurality of monitoring nodes can complete the monitoring operation for the same network node independently, so as to avoid the influence caused by network jitter. As shown in fig. 2, the method includes:
Step S200: the central control server acquires each original task pre-configured in the monitoring database and determines a network node corresponding to each original task; and generating a monitoring task to be executed according to the network node corresponding to the original task.
Wherein the WEB server dynamically configures monitoring tasks (i.e., raw tasks) into the monitoring database, each raw task being for testing at least one preset function of at least one network node. Accordingly, each original task at least comprises the following information: network node to be monitored, function identification of preset function to be monitored.
The network node to be monitored is the network node corresponding to the original task, and the specific number of the network nodes can be one or more. Optionally, when the number of network nodes to be monitored included in one original task is multiple, the central control server splits the original task into multiple monitoring tasks according to the number of network nodes, and each split monitoring task corresponds to one network node respectively. In addition, the preset function to be monitored corresponds to the task type of the monitoring task, and specifically includes: the type of monitoring whether the port survives (e.g., detecting 80 a port failed function), and/or the type of detecting whether HTTP service is normal, etc. When the number of the preset functions to be monitored included in one monitoring task is multiple, optionally, the central control server splits the original task into multiple monitoring tasks according to the number of the preset functions, and each split monitoring task corresponds to one preset function respectively. For example, assuming that one original task is used to monitor a preset function in M of N network nodes, the central control server may split the original task into n×m monitoring tasks, so that each monitoring task corresponds to a preset function of one network node, respectively. Wherein N, M is a natural number.
Step S210: the central control server respectively sends the monitoring tasks corresponding to the network nodes to a plurality of monitoring nodes respectively connected with the network nodes so that each monitoring node respectively sends the monitoring tasks to the network nodes; the monitoring task comprises monitoring period information.
In essence, in step S200, the central control server determines a plurality of monitoring tasks to be executed according to the monitoring database, and in order to facilitate execution, each monitoring task corresponds to a preset function of a network node in this embodiment. Accordingly, in this step and the subsequent steps, for convenience of description, only one monitoring task corresponding to a preset function of one network node is taken as an example, and in practical cases, the number of monitoring tasks and network nodes are multiple.
In addition, in order to improve the monitoring accuracy, a plurality of monitoring nodes which are respectively connected with the network nodes are preset for each network node, and each function of the network node is monitored by the plurality of monitoring nodes which are mutually independent, so that the accuracy is improved. Of course, besides the fact that the same network node needs to be connected with a plurality of monitoring nodes, the same monitoring node may also be connected with a plurality of network nodes respectively.
Specifically, for a monitoring task, the central control server first determines a network node corresponding to the monitoring task and a preset function to be tested. For example, assume that a network node corresponding to the monitoring task is a cache node in beijing, and in order to test the cache node, three monitoring nodes, such as a monitoring node a, a monitoring node B and a monitoring node C, respectively connected to the cache node are deployed in advance. Correspondingly, the central control server respectively transmits the monitoring tasks to the monitoring node A, the monitoring node B and the monitoring node C. The monitoring tasks received by each monitoring node are the same. Each monitoring task at least comprises the following information: node identification of a network node to be monitored, function identification of a preset function to be monitored, and monitoring period information. Wherein the monitoring period information includes: the period duration and the period number are used for indicating the network node to feed back the periodic monitoring values corresponding to the periods, so that the problem that the monitoring value at a single time point is affected by network jitter and is inaccurate is solved. For example, the period duration in this embodiment is 1 second, and the number of periods is 5, where the period duration refers to the duration of a single period, and accordingly, the network node needs to acquire the monitoring value every 1 second within 5 seconds, so as to acquire 5 periodic monitoring values.
Step S220: after each monitoring node issues the monitoring task to the network node, a plurality of periodic monitoring values corresponding to the monitoring period information contained in the monitoring task and returned to the monitoring node by the network node are obtained.
Specifically, after the monitoring node a, the monitoring node B, and the monitoring node C send the monitoring tasks to the network node respectively, the network node will feed back a plurality of periodic monitoring values to the monitoring node a, the monitoring node B, and the monitoring node C respectively.
For example, taking the monitoring node a as an example, after the monitoring node a sends a monitoring task for detecting whether the 80 ports are unobstructed to the network node, the network node determines the number of periods to be monitored and the time interval during each period according to the monitoring period information contained in the monitoring task to obtain a plurality of periodic monitoring values. Specifically, the plurality of periodic monitoring values corresponding to the monitoring period information contained in the monitoring task, which are returned by the network node to the monitoring node a, are determined by: firstly, after receiving a monitoring task issued by the monitoring node, the network node acquires the period duration and the period number in monitoring period information contained in the monitoring task; and then, the network node acquires the periodic monitoring values corresponding to the monitoring tasks once every other period time, and when the number of the acquired periodic monitoring values reaches the number of the periods, the network node sends the plurality of periodic monitoring values corresponding to the number of the periods to the monitoring node. For example, in this example, the network node acquires the periodic monitoring values corresponding to the monitoring task once every 1 second, and when the number of acquired periodic monitoring values reaches 5, sends the 5 periodic monitoring values to the monitoring node. Accordingly, monitoring node a will receive 5 periodic monitoring values from the network node. Similarly, the monitoring node B, C will also receive 5 periodic monitoring values from the network node. Of course, the specific values of the 5 periodic monitoring values received by each monitoring node may be different.
Step S230: and each monitoring node calculates a node monitoring value of the network node corresponding to the monitoring task according to a plurality of periodic monitoring values which are returned to the monitoring node by the network node and correspond to the monitoring period information contained in the monitoring task and a preset node operation rule.
The specific value range of the periodic monitoring value fed back by the network node is determined by the actual application scene, and the value range can be a numerical value or other types, and the invention is not limited to the numerical value. In a specific example, the specific value range of the periodic monitoring value fed back by the network node is 0 and 1, and the abnormal function is indicated when the value is 0, and the normal function is indicated when the value is 1. In order to ensure the accuracy of the result, the node monitoring value of the network node corresponding to the monitoring task needs to be calculated according to a preset node operation rule. The node monitoring value is used for reflecting the monitoring value of the network node corresponding to the monitoring task, which is monitored by the monitoring node.
In this embodiment, the preset node operation rule includes: according to the monitoring time of each periodic monitoring value, giving corresponding weight to each periodic monitoring value, and executing weighting operation on each periodic monitoring value to obtain a node monitoring value of the network node corresponding to a monitoring task; wherein, the later the monitoring time is, the higher the corresponding weight of the periodic monitoring value is. For example, assume that the 5 periodic monitoring values received by the monitoring node a are in order of the monitoring time: 11011, giving the highest weight to the monitoring value with the last monitoring time and giving the smallest weight to the monitoring value with the last monitoring time, thereby obtaining the node monitoring value of 1 on the monitoring node A. The node monitoring values of other monitoring nodes are determined in a similar manner, and are not described in detail herein. Of course, the preset node operation rule may be an average value calculation rule, and the present invention is not limited thereto, as long as an error caused by fluctuation of a single monitor value can be prevented.
Step S240: the central control server respectively acquires node monitoring values, corresponding to the monitoring tasks, of the network nodes reported by the monitoring nodes; the node monitoring value of the network node corresponding to the monitoring task reported by each monitoring node is determined according to a plurality of periodic monitoring values corresponding to the monitoring period information contained in the monitoring task and returned by the network node.
For example, in the above example, the monitoring node a, the monitoring node B, and the monitoring node C acquire the node monitoring values reported to the monitoring node by the network node independently of each other. For example, in the above example, if the monitoring node a determines that the node monitoring value on the monitoring node a is 1 according to the received 5 periodic monitoring values 11011, the monitoring node a reports the node monitoring value 1 to the central control server. It is assumed that the node monitoring value reported by the monitoring node B is also 1, and the node monitoring value reported by the monitoring node C is 0. Correspondingly, the central control server acquires three node monitoring values, namely 1, 1 and 0.
Step S250: and the central control server determines the monitoring result of the network node corresponding to the monitoring task according to the node monitoring value of the network node corresponding to the monitoring task, which is reported by each monitoring node.
Specifically, the central control server determines a monitoring result of the network node corresponding to the monitoring task according to the monitoring value of each node and a preset result operation rule. The preset result operation rule can be flexibly set, for example, specific values of monitoring values of each node can be respectively determined, the occurrence number of each specific value is determined, and the value with the largest occurrence number is determined as the monitoring result of the network node corresponding to the monitoring task. For example, in this example, since the three node monitoring values are 1, and 0, respectively, where the number of occurrences of the value 1 is the largest, the monitoring result of the network node corresponding to the monitoring task is determined to be 1. The meaning of the monitoring result is as follows: the 80 ports of the network node are in a clear state.
Step S260: the central control server stores the monitoring results of each network node corresponding to each monitoring task into a preset monitoring result table respectively; and displaying the monitoring result table, and/or realizing scheduling for each network node according to the monitoring result table.
In practical situations, the central control server may acquire the monitoring results of each network node corresponding to each monitoring task, so in order to facilitate the utilization of the monitoring results, in this embodiment, each obtained monitoring result is further stored in a preset monitoring result table.
For the content in the monitoring result table, the following two utilization modes can be adopted: the first way is: and displaying the monitoring result table so that a system manager can perform operations such as system maintenance and the like according to the display result. The second mode is as follows: and according to the monitoring result table, scheduling for each network node is realized. For example, when a client request is received, a network node with normal function is selected for the client request according to the type of the client request, and the network node with abnormal function is avoided, so that the problem of access failure caused by the abnormal function of the network node is prevented.
In summary, by means of the method in this embodiment, the same monitoring task aimed at the same network node can be sent to multiple monitoring nodes, the multiple monitoring nodes monitor in parallel, and the final result is determined by integrating the monitoring data of the multiple monitoring nodes, so that the monitoring accuracy is improved. And each monitoring node can acquire a plurality of periodic monitoring values corresponding to a plurality of periods of the network node respectively, and the node monitoring values corresponding to the monitoring node of the network node are determined by integrating the plurality of periodic monitoring values, so that inaccurate results caused by abnormal factors such as network jitter and the like are prevented. Therefore, the accuracy of the monitoring result can be greatly improved, and the interference of external factors can be prevented. This way it can be monitored whether the DNS node or HTTP server in the CDN system is properly served.
