Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
In view of the above object, a first aspect of the embodiments of the present invention provides an embodiment of a method for batch grouping management of servers. Fig. 1 is a schematic diagram illustrating an embodiment of a method for batch group management of a server according to the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps performed at the maintenance device side:
s01, detecting the distance between any two hosts through a route tracking command;
s02, dividing all the hosts into a preset number of host clusters through a hierarchical clustering algorithm based on the distance between any two hosts;
s03, respectively selecting one host from each host cluster as a relay point; and
and S04, sending a command to the relay point, and issuing the command to other hosts in the host cluster by the relay point.
In this embodiment, a management program is used to access the data center, and perform batch management on the servers in the data center. The grouping algorithm uses a hierarchical clustering grouping algorithm to divide all the hosts into K groups according to tresert data among the hosts as a basis for measuring network delay among the hosts. One host is selected from each group as a relay point, and the management program firstly sends scripts of task execution, result acquisition and the like and files to be transmitted to the relay point and then the relay point continuously issues the scripts and the files to be transmitted to each managed host.
In this embodiment, the purpose of the clustering and grouping algorithm is to group the hosts in the network with the least latency required for the interconnection of the managed hosts. Hierarchical clustering is a clustering algorithm, and has two modes of top-down splitting and bottom-up merging, and we use the mode of bottom-up merging here. It may divide the samples in the data set into several disjoint subsets according to distance, each subset being a cluster. Hierarchical clustering has the advantage of flexible selection of the number of clusters and the cluster centers. When a batch task is issued, the management program issues the task and the management script to the relay point, and then the relay point sends the task and the management script to other managed hosts of each cluster, so that the time for task execution and file transmission is greatly shortened.
In some embodiments of the invention, further comprising: and receiving the final processing result returned by the relay point, wherein the final processing result is obtained by combining the processing results of the other hosts received by the relay point.
In this embodiment, when receiving the return values of other managed hosts, the relay points return the results to the management program in a unified manner, and merge, analyze and display the results.
In some embodiments of the invention, detecting the distance between any two hosts through the traceroute command comprises: obtaining the return time of sending the ICMP packet for three times between any two hosts through the routing tracking command, and calculating the average value of the return time; the distance between the two hosts is represented based on the average.
The Tracert command is a network command for detecting the number of routing nodes, and may list the routing nodes that the packet passes through and its delay per hop in the IP network, where the fields include the time to live, the return time of the ICMP packet sent three times, and the routing nodes that pass through. In this embodiment, the average of the return times of three times an ICMP packet is sent is used to measure the distance between two hosts.
In some embodiments of the present invention, dividing all hosts into a preset number of host clusters by a hierarchical clustering algorithm based on the distance between any two hosts comprises: merging two hosts/clusters with the closest distance into one cluster to obtain a plurality of clusters, and judging whether the number of the obtained clusters is greater than a preset number or not; if the obtained number of clusters is larger than the preset number, recalculating the distance between the clusters and returning to the previous step; and if the obtained cluster number is not more than the preset number, determining that all the hosts are divided into the host clusters with the preset number.
In this embodiment, a hierarchical clustering grouping algorithm and Tracert data are used to construct a grouping model for managed hosts. If there are m managed hosts, then assume the unlabeled dataset as
The task of the algorithm is to cluster the data sets into k clusters C = C 1 ，C 2 ，…C k . Each sample in the data set is first treated as a cluster. Collecting Tracert data among clusters, calculating the average value of the return time of the ICMP packet sent three times, taking the average value as a parameter for measuring the distance between two clusters, and recording the average value as dist (x) i ，x j ). The two samples whose data points are closest to each other are merged, assumed to be u. The distance between clusters is recalculated. The calculation method of the distance from u to each other cluster is as follows: the average of the distances of the other clusters to each sample in u is calculated. And selecting the two clusters with the minimum distance again for combination. Constantly repeating the calculationThe distances are merged into clusters until the data points are divided into K groups. The selection of K is crucial to the grouping result, and may even result in poor operation result, so it should be generally selected by operation and maintenance personnel.
In some embodiments of the present invention, selecting a host in each host cluster as a relay point comprises: and randomly selecting one host in each host cluster as a relay point.
In this embodiment, one host is arbitrarily selected from each cluster as a relay point of the cluster. And accessing the management program to a management center, and performing batch host management according to the constructed packet model. When there is a batch management task, the management program firstly constructs scripts of task execution, result acquisition and the like, and sends the scripts and files to be issued to each relay point. And each relay point sends the task execution script and the task execution file to other managed hosts of the cluster according to the script content.
In some embodiments of the present invention, selecting a host in each host cluster as a relay point comprises: and selecting one host in each host cluster as a relay point according to the CPU utilization rate and/or the memory utilization rate and/or the IO utilization rate of the server.

When there are batch management tasks, the management program firstly constructs scripts for task execution, result acquisition and the like, and sends the scripts and files to be issued to each relay point.
