Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Fig. 1 is a flowchart of a virtualization platform thread control method provided by an embodiment of the present invention. The method provided by this embodiment is configured to be executed in a virtual machine. As shown in Fig. 1, the method specifically includes:

Step 101, when the client on the virtual machine starts multi-threaded operation for multiple tasks issued by the control center, starts the monitoring thread, and monitors the resources of the virtual machine occupied by all threads;

The virtualization platform includes a control center and at least one physical machine. Through virtualization technology, one physical machine can be virtualized into multiple virtual machines. Each virtual machine can run different operating systems and applications, and is used to run operating systems and application or data communication. The control center can communicate and interact with all virtual machines.

The client of the network application is installed in the virtual machine, and the control center can control the client deployed on the virtual machine. Specifically, the control center will send many tasks to the client, and the client will create one or more threads to complete different tasks. An example is as follows: install a security client on a virtual machine, and the control center issues a full scan or partial scan task to the client in the virtual machine, so that the client creates one or more threads to complete the task according to the task issued by the control center scanning.

When the client on the virtual machine starts multi-threaded operation for multiple tasks issued by the control center, the monitoring thread is started to monitor the resources of the virtual machine occupied by all the threads running on the client.

Step 102, judging whether the occupied resource is smaller than a preset first limit threshold corresponding to the virtual machine;

The more threads opened by the client on the virtual machine, the more resources of the virtual machine are occupied. In order to prevent the resource consumption of the virtual machine from being too large and affecting the overall working performance of the virtual machine, a first resource occupation threshold is set in advance for the virtual machine.

The first limit threshold is used to mark the online usage of virtual machine resources. The content of the first limit threshold depends on the type of resource consumed. The resource type specifically includes: central processing unit CPU, memory, input and output interface IO and network. Since the resource allocation and operating performance of different virtual machines are different, the restrictions on occupied resources are not completely the same. Therefore, the specific content of the first limit threshold is set according to actual application needs, and this embodiment does not Limitations, for example as follows:

The first limit threshold corresponding to the virtual machine includes: the CPU resources consumed by the client account for 5% of the entire virtual machine's CPU resources, and the memory resources consumed by the client account for 5% of the entire virtual machine's memory resources. %, the network resources consumed by the client are limited to 5% of the entire network resources of the virtual machine.

The first limit threshold is the cut-off point of the virtual machine’s work performance. When the resources of the virtual machine occupied by all the threads running on the client are greater than or equal to the preset first limit threshold, it indicates that the overall work performance of the virtual machine begins to decline; when the client runs If the resources of the virtual machine occupied by all the threads are less than the preset first limit threshold, it indicates that the virtual machine has good working performance.

Step 103, if it is determined that the occupied resource is greater than or equal to the first limit threshold, control low-level threads to sleep according to the thread priority information issued by the control center.

After the virtual machine compares the resources of the virtual machine currently occupied by all threads with the preset first limit threshold, if it determines that the occupied resources are greater than or equal to the first limit threshold, it indicates that the overall performance of the virtual machine begins to decline. It should be noted that when the proportion of the first limit threshold is limited to multiple resources, the resource occupied by the thread currently running on the virtual machine is greater than or equal to one of them, that is, greater than or equal to the preset first limit threshold. Therefore, the virtual machine controls low-level thread sleep according to the thread priority information issued by the control center in advance. In order to prevent excessive occupation of virtual machine resources, reduce the overall performance of the virtual machine, and affect normal business.

It should be noted that the thread priority information issued by the control center is the priority set by the control center according to the importance of the thread type on the client, and can be adjusted according to specific application scenarios. This embodiment does not limit this, for example , low-level threads include: scanning threads and vulnerability repair threads.

In the virtualization platform thread control method provided in this embodiment, when the client on the virtual machine starts multi-threaded operation for multiple tasks issued by the control center, the monitoring thread is started to monitor the resources of the virtual machine occupied by all threads. Knowing that the occupied resources are greater than or equal to the first limit threshold corresponding to the virtual machine, control low-level threads to sleep according to the thread priority information issued by the control center. It realizes the dynamic control of the working state of the thread according to the resource occupation of the virtual machine, and executes finer-grained control of the client thread to prevent excessive resource occupation of the virtual machine, reduce the overall performance of the virtual machine, and affect normal business.

Fig. 2 is a flow chart of another virtualization platform thread control method provided by an embodiment of the present invention. The method provided by this embodiment is configured to be executed in a virtual machine. As shown in Fig. 2, the method specifically includes:

Step 201, when the client on the virtual machine starts multi-threaded execution for multiple tasks issued by the control center, send a resource control request to the control center;

When the client on the virtual machine starts multi-threaded execution for multiple tasks issued by the control center, it sends a resource control request to the control center. Wherein, the virtual machine can compare the number of threads opened by the client for multiple tasks issued by the control center, and/or the thread type with preset threshold information, to determine whether to send a resource control request to the control center. Examples are as follows:

The upper limit of the number of threads in the preset threshold information is 5. When the virtual machine determines that the number of threads opened by the client for multiple tasks issued by the control center is greater than or equal to 5, it sends a resource control request to the control center.

Step 202, receiving a first limit threshold corresponding to the virtual machine allocated by the control center, the first limit threshold is allocated by the control center according to the task type issued to the virtual machine;

After receiving the resource control request sent by the virtual machine, the control center assigns the virtual machine the corresponding first limit threshold according to the task type issued to the virtual machine. For example, when the control center sends the virtual machine the If the task type is a task that requires relatively high performance of the virtual machine, such as the high real-time performance of instant messaging, etc., the first limit threshold assigned to the virtual machine is low. When the task type issued by the control center to the virtual machine belongs to the For tasks with relatively low performance requirements of the virtual machine, such as transferring files, the first limit threshold allocated to the virtual machine is relatively high.

The virtual machine receives the first limit threshold assigned by the control center and corresponding to the virtual machine.

Step 203, start the monitoring thread, and obtain the monitoring frequency according to the preset monitoring trigger strategy;

Start the monitoring thread and obtain the monitoring frequency according to the preset monitoring trigger strategy. The monitoring trigger strategy is set according to the actual application needs, for example:

Obtain the monitoring frequency corresponding to the current time according to the preset time monitoring strategy, or,

Obtain the monitoring frequency corresponding to the currently received task quantity according to the preset task monitoring policy.

Step 204, using the monitoring frequency to monitor the resources of the virtual machine occupied by all threads;

Step 205, judging whether the occupied resource is smaller than a preset first limit threshold corresponding to the virtual machine;

Step 206, if it is determined that the occupied resource is greater than or equal to the first limit threshold, control low-level threads to sleep according to the thread priority information issued by the control center;

For the specific implementation process of step 204-step 206, refer to step 101-step 103 in the embodiment shown in Figure 1, and its implementation principle is similar,

Step 207, if it is determined that the occupied resource is less than the first limit threshold, wake up the thread in the dormant state.

With the end of other threads on the virtual machine, the virtual machine resources occupied by the thread gradually fall below the first limit threshold, which means that under the premise of ensuring the working performance of the virtual machine, the currently executing thread of the virtual machine is not saturated, so it is in the The thread in the sleep state continues to perform tasks, such as the scanning thread continues to scan. In this way, the working state of the thread is dynamically controlled according to the resource occupation of the virtual machine, and more tasks are performed on the premise of ensuring the working performance of the virtual machine.

In the virtualization platform thread control method provided in this embodiment, when the client on the virtual machine starts multi-threaded operation for multiple tasks issued by the control center, the monitoring thread is started, and all threads are monitored using the monitoring frequency corresponding to the monitoring trigger strategy The resources of the virtual machine occupied, if it is determined that the occupied resources are greater than or equal to the first limit threshold corresponding to the virtual machine, then according to the thread priority information issued by the control center, the low-level thread is controlled to sleep; If the occupied resource is less than the first limiting threshold, wake up the thread in the dormant state. Realize the dynamic control of the working state of the thread according to the resource occupation of the virtual machine, and perform more tasks on the premise of ensuring the working performance of the virtual machine.

Figure 1 and Figure 2 are aimed at the scenario where too many threads on the client lead to excessive resource consumption of the virtual machine, and the embodiment shown in Figure 3 shows that the excessive consumption of at least one virtual machine on the physical machine causes the resource consumption of the physical machine where it resides Excessive scenarios are described in detail as follows:

Fig. 3 is a flow chart of another virtualization platform thread control method provided by an embodiment of the present invention. The method provided by this embodiment is configured to be executed in a virtual machine, as shown in Fig. 3 , based on the above embodiment, the method also Specifically include:

Step 301, sending resource occupation information of the virtual machine to the control center;

When the client on the virtual machine starts multi-threaded operation for multiple tasks issued by the control center, it starts the monitoring thread, monitors the resources of the virtual machine occupied by all threads, and sends the obtained resource occupation information of the virtual machine to the control center. The specific manifestations of the resource occupation information of the virtual machine include: percentage form, such as 20%, the control center pre-allocates all resources for the virtual machine, so the control center can know the specific amount of resources currently consumed by knowing the 20% , or, the virtual machine directly uploads the specific amount of resources currently consumed, such as 1G.

Step 302: Receive a dormancy control instruction carrying a thread identifier sent by the control center according to the thread priority information, the dormancy control instruction is obtained by the control center for all virtual machines on the physical machine to which the virtual machine belongs After the resource occupation information is determined, it is sent after it is determined that the resources of the physical machine occupied by all virtual machines are greater than or equal to a preset second limit threshold corresponding to the physical machine;

The more threads opened by the client on the virtual machine, the larger the resources of the virtual machine are occupied, and the resources of the physical machine are also occupied. In order to prevent excessive resource consumption of the physical machine from affecting the overall performance of the physical machine, a second limit threshold of resource occupation is set in advance for the physical machine.

The second limit threshold is used to mark the online usage of physical machine resources. The content of the second limit threshold depends on the type of resource consumed. The resource type specifically includes: central processing unit CPU, memory, input and output interface IO and network. Since different physical machines have different resource ratios and operating performances, the restrictions on occupied resources are not exactly the same. Therefore, the specific content of the second limit threshold is set according to actual application needs, and this embodiment does not Limitations, for example as follows:

The second limit threshold corresponding to the physical machine includes: the CPU resources consumed by the client account for 5% of the entire physical machine's CPU resources, and the memory resources consumed by the client account for 5% of the entire physical machine's memory resources. %, the network resources consumed by the client are limited to 5% of the entire network resources of the physical machine.

The second limit threshold is the cut-off point for the performance of the physical machine. When the resources of the physical machine occupied by all the threads run by the clients of all virtual machines on the physical machine are greater than or equal to the preset second limit threshold, it means that the overall performance of the physical machine starts decrease; when the resources of the physical machine occupied by all the threads run by the clients of all the virtual machines on the physical machine are less than the preset second limit threshold, it indicates that the physical machine has good performance.

When the control center receives the resource occupation information sent by at least one virtual machine deployed on the physical machine, and then judges whether the resources of the physical machine occupied by all the virtual machines are smaller than a preset second limit threshold corresponding to the physical machine; If it is determined that the occupied resource is greater than or equal to the second limit threshold, then according to the thread priority information, send the sleep control instruction carrying the thread identifier to the virtual machine with the low-level thread.

Step 303, controlling the thread corresponding to the thread identifier to sleep;

The virtual machine with the low-level thread controls the thread corresponding to the thread identifier to sleep according to the instruction of the control center.

Step 304: Receive a wake-up control instruction carrying a thread identifier sent by the control center, where the wake-up control instruction is sent after the control center determines that the resources of the physical machine occupied by all virtual machines are less than the second limit threshold of;

With the end of other threads on the virtual machine, the physical machine resources occupied by the virtual machine are gradually lower than the second limit threshold, which means that under the premise of ensuring the performance of the physical machine, the currently executing threads of the virtual machine are not saturated, so that before waking up A thread in a dormant state continues to perform tasks, such as a scanning thread continuing to scan. Therefore, a wake-up control instruction carrying a thread ID is sent to the virtual machine that previously had a low-level thread.

Step 305, wake up the thread in the dormant state corresponding to the thread identifier.

The virtual machine wakes up the previously dormant thread according to the thread ID to continue executing the task, for example, the scanning thread continues to scan. In this way, the working state of the thread can be dynamically controlled according to the resource occupation of the physical machine, and more tasks can be performed on the premise of ensuring the working performance of the virtual machine.

In the virtualization platform thread control method provided in this embodiment, after the control center obtains the resource occupation information of all virtual machines on the physical machine to which the virtual machine belongs, it determines whether the resources of the physical machines occupied by all virtual machines are less than the preset 1. Sending after the second limit threshold corresponding to the physical machine, according to the thread priority information, the corresponding thread on the virtual machine with low-level threads is controlled to sleep and wake up. Realize the dynamic control of the working state of the thread according to the resource occupation of the virtual machine, and implement finer-grained control of the client thread to prevent excessive resource occupation of the virtual machine, reduce the overall performance of the virtual machine, and affect normal business.
