S103, obtaining a second state of each virtual machine according to second state judgment information and a second judgment rule of each virtual machine; wherein the second judgment rule is preset;

specifically, the server may obtain second state judgment information of each virtual machine, and then obtain the second state of each virtual machine according to the second state judgment information and the second state judgment rule. The second state judgment information may include at least one type of information among the first type of judgment information of the virtual machine, the second type of judgment information of the virtual machine, and the third type of judgment information of the virtual machine, where each type of judgment information is set according to actual experience, and the embodiment of the present invention is not limited. The second state may include both active and inactive states. The second state judgment rule is preset and is set according to actual experience, and the embodiment of the present invention is not limited. The specific process for obtaining the second state of each virtual machine is described below, and is not described herein again.

And S104, performing resource allocation processing on each virtual machine according to the first state and the second state of each virtual machine.

Specifically, after obtaining the first state and the second state of each virtual machine, the server may perform resource allocation processing on each virtual machine according to the first state and the second state of each virtual machine, where the resource allocation processing may include resource allocation up processing, resource allocation down processing, and resource recovery processing on the virtual machine.

For example, when the first state of the virtual machine is idle and the second state is active, the resource reallocation process may be performed on the virtual machine. When the first state of the virtual machine is idle and the second state of the virtual machine is not in use, resource recovery processing can be performed on the virtual machine.

According to the resource management method for the virtual machines provided by the embodiment of the invention, the basic information of each virtual machine is regularly acquired, the first state of each virtual machine is acquired according to the basic information and the first judgment rule of each virtual machine, the second state of each virtual machine is acquired according to the second state judgment information and the second judgment rule of each virtual machine, and then the resource allocation processing is performed on each virtual machine according to the first state and the second state of each virtual machine, so that the resource of each virtual machine can be automatically managed, and the resource allocation efficiency of the virtual machines is improved. In addition, different states of the virtual machine are obtained by using the basic information and the second state judgment information of the virtual machine, and the resources of the virtual machine are allocated based on the information of different dimensions of the virtual machine, so that the resource allocation accuracy of the virtual machine is improved.

On the basis of the foregoing embodiments, further, the second state judgment information includes at least one type of information among first type judgment information, second type judgment information, and third type judgment information of the virtual machine; correspondingly, the obtaining the second state of each virtual machine according to the second state judgment information and the second judgment rule of each virtual machine includes:

and acquiring a second state of the virtual machine according to at least one type of information of the first type judgment information, the second type judgment information and the third type judgment information of the virtual machine and a corresponding second state judgment rule.

Specifically, the second state judgment information may include at least one of the first type judgment information of the virtual machine, the second type judgment information of the virtual machine, and the third type judgment information of the virtual machine. The first type of judgment information of the virtual machine may include parameter information such as a user usage rate of the virtual machine, an available memory, a number/second of IO reads of a file system, a number/second of IO writes of the file system, a number/s of MB reads of the file system, and a number/s of MB writes of the file system. The second type of judgment information of the virtual machine may include operating system login information, a user operation log, a system log, and an application log of the virtual machine. The third type judgment information of the virtual machine may include application version installation information of the virtual machine, that is, an application version of each application installed on the virtual machine. Wherein, each type of judgment information is set according to actual experience, and the embodiment of the invention is not limited. After the server obtains at least one type of information of the first type of judgment information of the virtual machine, the second type of judgment information of the virtual machine and the third type of judgment information of the virtual machine, the server obtains the second state of each virtual machine according to the at least one type of information and the corresponding second state judgment rule.

For example, the server may obtain the first type of determination information as the second state determination information, where the first type of determination information of the virtual machine includes a user usage rate of the virtual machine, an available memory, a number of IO reads/sec of a file system, a number of IO writes/sec of the file system, a number of MB reads/s of the file system, and a number of MB writes/s of the file system. The first type of judgment information may be acquired periodically, for example, every 5 seconds. The second state judgment rule corresponding to the first type judgment information is as follows: in one period, the user utilization rate of the virtual machine, the available memory, the read IO times/second of the file system, the write IO times/second of the file system, the read MB/s of the file system or the write MB/s of the file system have obvious fluctuation. The existence of the significant fluctuation is set according to practical experience, and the embodiment of the invention is not limited. The significant fluctuation may mean that the number of times that one parameter information included in the first type of judgment information exceeds the corresponding fluctuation range in a single period is greater than m, where m is set according to practical experience, for example, 20% of the total collection number in the single period. The fluctuation range is preset and is set according to practical experience, and the embodiment of the invention is not limited.

For the user usage rate of the virtual machine, the server may statistically obtain a total number of acquisition times N in a single period, and if the single period is 7 days and the user usage rate of the virtual machine is acquired every 5 seconds, the total number of acquisition times N for acquiring the user usage rate of the virtual machine in 7 days is 120960 times. And comparing the user utilization rate of the virtual machine acquired each time with the corresponding fluctuation range, wherein if the user utilization rates of N virtual machines in the user utilization rates of the virtual machines acquired N times exceed the corresponding fluctuation range and N is greater than m, the second state of the virtual machine is in use. The fluctuation range of the user utilization rate of the virtual machine can be determined according to an average value p of the user utilization rate of the virtual machine in a single period, the average value of the user utilization rate of the virtual machine in the single period is calculated, namely the user utilization rates of the N virtual machines are averaged, p (1+ 10%) can be used as an upper limit value when the user utilization rate of the virtual machine exceeds the corresponding fluctuation range, and p (1-10%) can be used as a lower limit value when the user utilization rate of the virtual machine exceeds the corresponding fluctuation range.

For the available memory of the virtual machine, the number of IO reads/second of the file system, the number of IO writes/second of the file system, the number of MB/s reads of the file system, or the MB/s writes of the file system, the specific process for determining the second state of the virtual machine is similar to the determination process for determining the second state of the virtual machine according to the user utilization rate of the virtual machine, and details are not repeated here.

If any parameter information in the first type judgment information of the virtual machine meets the corresponding second state judgment rule, the second state of the virtual machine is in use; and if all the parameter information in the first type judgment information of the virtual machine does not meet the corresponding second state judgment rule, the second state of the virtual machine is not used.

The second state judgment rule corresponding to the second type judgment information may include at least one judgment condition of judgment condition 1, judgment condition 2, judgment condition 3, and judgment condition 4. The judgment condition 1 includes: in a single cycle, there is login information in the operating system login information of the virtual machine. Wherein the login information can be output by using last command. The judgment condition 2 includes: in a single period, the new execution command exists in the bash _ history file of the user operation log of the virtual machine. The judgment condition 3 includes: in a single period, the messages file of the system log of the virtual machine has log of login or transmission information of ftp, ssh and sftp. The judgment condition 4 includes: log files of application logs of the virtual machines have application login information in a single period.

In a single period, if login information exists in the operating system login information of the virtual machine, and the operating system login information of the virtual machine meets a judgment condition 1, the virtual machine meets a second state judgment rule corresponding to the second type of judgment information, and the second state of the virtual machine is in use; in a single period, if a newly added execution command exists in a bash _ history file of a user operation log of the virtual machine, and the user operation log of the virtual machine meets a judgment condition 2, the virtual machine meets a second state judgment rule corresponding to the second type of judgment information, and the second state of the virtual machine is in use; in a single period, if a message file of a system log of a virtual machine has an ftp, ssh, sftp log, and the system log of the virtual machine satisfies a judgment condition 3, the virtual machine satisfies a second state judgment rule corresponding to the second type of judgment information, and the second state of the virtual machine is in use; in a single period, if application login information exists in a systemeout log file of an application log of a virtual machine, and the application log of the virtual machine meets a judgment condition 4, the virtual machine meets a second state judgment rule corresponding to the second type of judgment information, and the second state of the virtual machine is in use. That is, any information in the second type judgment information of the virtual machine satisfies any judgment condition in the second state judgment rule corresponding to the second type judgment information, the virtual machine satisfies the second state judgment rule corresponding to the second type judgment information, and the second state of the virtual machine is in use. Otherwise, the state of the virtual machine is not used.

The server may obtain the third type determination information as the second state determination information, where the third type determination information of the virtual machine includes application version installation information of the virtual machine, and the application version installation information may include version installation information of one application or version installation information of multiple applications. The second state judgment rule corresponding to the third type judgment information may include: in one period, the version installation information of any application of the virtual machine comprises that the application version is not lower than the corresponding preset application version. Comparing the application version of each application of the virtual machine with the corresponding preset application version, and if the application versions of all the applications are not lower than the corresponding preset application versions, the virtual machine satisfies a second state judgment rule corresponding to the third type judgment information, and the second state of the virtual machine is in use. And if the application version of one application is lower than the corresponding application version in the virtual machine, the virtual machine does not meet a second state judgment rule corresponding to the third type judgment information, and the second state of the virtual machine is not used.

The server may obtain the first type judgment information and the second type judgment information as the second state judgment information, and the second state judgment rule corresponding to the first type judgment information and the second type judgment information includes a second state judgment rule corresponding to the first type judgment information and a second state judgment rule corresponding to the second type judgment information. If the virtual machine meets a second state judgment rule corresponding to the first type judgment information or the virtual machine meets a second state judgment rule corresponding to the second type judgment information, the second state of the virtual machine is in use; and if the virtual machine does not meet the second state judgment rule corresponding to the first type judgment information and the virtual machine does not meet the second state judgment rule corresponding to the second type judgment information, the second state of the virtual machine is not used.

The server may obtain the second type judgment information and the third type judgment information as the second state judgment information, and the second state judgment rule corresponding to the second type judgment information and the third type judgment information includes a second state judgment rule corresponding to the second type judgment information and a second state judgment rule corresponding to the third type judgment information. If the virtual machine meets a second state judgment rule corresponding to the second type judgment information or the virtual machine meets a second state judgment rule corresponding to the third type judgment information, the second state of the virtual machine is in use; and if the virtual machine does not meet the second state judgment rule corresponding to the second type judgment information and the virtual machine does not meet the second state judgment rule corresponding to the third type judgment information, the second state of the virtual machine is not used.

The server may obtain the first type judgment information and the third type judgment information as the second state judgment information, and the second state judgment rule corresponding to the first type judgment information and the third type judgment information includes a second state judgment rule corresponding to the first type judgment information and a second state judgment rule corresponding to the third type judgment information. If the virtual machine meets a second state judgment rule corresponding to the first type judgment information or the virtual machine meets a second state judgment rule corresponding to the third type judgment information, the second state of the virtual machine is in use; and if the virtual machine does not meet the second state judgment rule corresponding to the first type judgment information and the virtual machine does not meet the second state judgment rule corresponding to the third type judgment information, the second state of the virtual machine is not used.

The server may obtain the first type judgment information, the second type judgment information, and the third type judgment information as the second state judgment information, and the second state judgment rule corresponding to the first type judgment information, the second type judgment information, and the third type judgment information includes a second state judgment rule corresponding to the first type judgment information, a second state judgment rule corresponding to the second type judgment information, and a second state judgment rule corresponding to the third type judgment information. If the virtual machine meets a second state judgment rule corresponding to the first type judgment information, the virtual machine meets the second state judgment rule corresponding to the second type judgment information or the virtual machine meets the second state judgment rule corresponding to the third type judgment information, the second state of the virtual machine is in use; and if the virtual machine does not meet the second state judgment rule corresponding to the first type judgment information, the virtual machine does not meet the second state judgment rule corresponding to the second type judgment information, and the virtual machine does not meet the second state judgment rule corresponding to the third type judgment information, the second state of the virtual machine is not used.

On the basis of the foregoing embodiments, further, the performing, according to the first state and the second state of each virtual machine, resource allocation processing on each virtual machine includes:

and if the first state of the virtual machine is idle and the second state of the virtual machine is in use, performing resource allocation reduction processing on the virtual machine.

Specifically, after determining that the first state of the virtual machine is idle and the second state is in use, the server may perform resource reallocation processing on the virtual machine, that is, reduce resources of the virtual machine, which indicates that the use frequency of the virtual machine is low. It can be understood that, before the resource upgrade processing is performed on the virtual machine, the resource downgrade processing confirmation information may be sent to the user of the virtual machine, and after the user agrees to perform the resource downgoing processing on the virtual machine, the user may also select the time for performing the resource downgoing processing; after the resource allocation reduction processing is carried out on the virtual machine, the result of the resource allocation reduction processing can be sent to a user of the virtual machine, so that the user can know the resource allocation change condition of the virtual machine in time.

For example, the resource allocation reduction process may be preset as follows: one CPU and two standard memories are reduced. And when the first state of the virtual machine is idle and the second state of the virtual machine is in use, reducing one CPU and two standard memories of the virtual machine. The standard memory is set according to actual needs, and the embodiment of the invention is not limited.

and if the first state of the virtual machine is idle and the second state of the virtual machine is not in use, performing application closing processing on the virtual machine, and performing resource recycling processing on the virtual machine after the first state of the virtual machine is idle and the second state of the virtual machine is not in use is judged and obtained next time.

Specifically, after determining that the first state of the virtual machine is idle and the second state is not in use, the server performs application shutdown processing on the virtual machine, that is, shuts down all applications on the virtual machine. The server periodically manages the resources of the virtual machine, the server also obtains a first state and a second state of the virtual machine in the next period, and if the first state of the virtual machine is idle and the second state of the virtual machine is not used, the server performs resource recycling processing on the virtual machine, namely deletes the virtual machine. When the resource recovery processing is performed on the virtual machine, the virtual machine may wait for a period of time, for example, wait for 30 days, so as to avoid that the virtual machine is deleted by mistake due to misjudgment of the server and cannot be recovered.

On the basis of the foregoing embodiments, further, the method for resource management of a virtual machine according to an embodiment of the present invention further includes:

and if the first state of the virtual machine is judged to be busy, performing resource allocation increasing processing on the virtual machine.

Specifically, after judging that the first state of the virtual machine is busy, the server performs resource allocation increasing processing on the virtual machine, that is, increases resources of the virtual machine. The first state of the virtual machine is busy, which indicates that the resources of the virtual machine are in shortage, and more resources need to be allocated to the virtual machine to improve the operating efficiency of the virtual machine. Before resource upgrading and allocating processing is carried out on the virtual machine, resource upgrading and allocating processing confirmation information can be sent to a user of the virtual machine, after the user agrees, the virtual machine is subjected to resource upgrading and allocating processing, and the user can select the time for carrying out the resource upgrading and allocating processing; after the resource upgrading and allocating processing is carried out on the virtual machine, the result of the resource upgrading and allocating processing can be sent to a user of the virtual machine, so that the user can know the resource allocation change condition of the virtual machine in time. It can be understood that, if the first state of the virtual machine is normal, it indicates that the current resources of the virtual machine can meet the operation requirement of the virtual machine, and the resource allocation processing is not required to be performed on the virtual machine.

For example, the resource upgrade process may be preset as follows: one CPU and two standard memories are added. And when the first state of the virtual machine is busy, adding a CPU and two standard memories for the virtual machine. The standard memory is set according to actual needs, and the embodiment of the invention is not limited.

s201, obtaining the shutdown days of each virtual machine according to the power state of each virtual machine within the preset days; wherein the basic information of each virtual machine comprises a power state;

specifically, the server may obtain a power state of each virtual machine within a preset number of days, determine whether the virtual machine is in a shutdown state or a startup state each day according to the power state of each virtual machine within the preset number of days, and if the power state obtained by the virtual machine each time within one day is power off, the virtual machine is in the shutdown state, otherwise, the virtual machine is in the startup state.
