Embodiment

In below describing, in order to illustrate instead of in order limiting, to have proposed the detail such as particular system structure, interface, technology, understand the application to thoroughly cut.But, it will be clear to one skilled in the art that and in other execution mode that there is no these details, also can realize the application.In other situation, omit the detailed description to well-known device, circuit and method, in order to avoid unnecessary details hinders the application's description.

Describe below in conjunction with accompanying drawing and concrete execution mode, and in order to facilitate brief and concise being described, the technical characterictic between the application's multiple different execution modes both can mutually distinguish also can part identical and its can be according to actual needs and staggered combination.

Refer to Fig. 1, Fig. 1 is the schematic flow sheet of information processing method first execution mode of the resource information acquisition server of the application's cloud computing, in the present embodiment, the information processing method of the resource information acquisition server of cloud computing includes but not limited to following steps.

Step S100, resource information acquisition server obtains the current disposal ability information of self.

In step S100, the current disposal ability of resource information acquisition server is with SPC(Server Processing Capability) definition, the ability when being used for refering in particular to resource information acquisition server and processing the capturing service of resource using information; Its specifically can be different according to cloud computing application scenarios, such as the number of tasks that gathers of the CPU usage of resource information acquisition server to cloud computing, I/O mouth read-write frequency or resource using information etc. is as the dimension of SPC.In addition, resource information acquisition server in the process of work, can be in real time, periodically or not timing obtain self SPC, in this no limit.

Step S101, more current disposal ability and default maximum processing capability, produce comparative result, and produce and whether report reference information accordingly according to comparative result.

In step S101, the default maximum processing capability of resource information acquisition server is with MPC(Max Process Capability) definition, for limiting the higher limit of SPC of resource information acquisition server.Be not difficult to find out, by MPC is set, can limit the ability of number of tasks that the CPU usage of resource information acquisition server to cloud computing, I/O mouth read-write frequency or resource using information gather etc.It should be noted that, because resource information collection only belongs to the lower business of rank in cloud computing, if resource information acquisition server takies the resource of cloud computing too much, will cause the important service such as scheduling, monitoring and the maintenance of cloud computing normally to carry out, therefore, need to limit by MPC the higher limit of SPC, so that the resource of cloud computing is applied in other important service more; In like manner, if SPC does not reach MPC, may cause system to carry out effectively monitoring etc. to all node resources, therefore, by setting the mode of MPC, the part resource that can ensure cloud computing is used in the business gathering in the resource information of specifying, so that the node that meets the condition that whether reports reference information is gathered.Wherein, the set-up mode that MPC is concrete and size etc., can set according to actual needs, in the scope of understanding, is not construed as limiting the art personnel.

Whether step S102, will report reference information to send to resource information to gather client.

In step S102, be not difficult to find out after step S101 compares the size of SPC and MPC, whether what generate reports reference information, can gather by whether reporting reference information to limit resource information the quantity of the resource using information that reports of client, and resource information acquisition server due to process resource using information quantity reduce, the value of its corresponding SPC diminishes corresponding.In like manner, by the reference information that whether reports of step S101, also can in the scope of the value of MPC, strengthen gradually the value of SPC, thereby gather the resource using information of the node of some, to facilitate follow-up monitoring resource and the scheduling etc. of carrying out cloud computing.In addition, whether reporting reference information can be also the resource using information that resource information acquisition server specifies all resource informations to gather clients to stop reporting at the appointed time all nodes, for example the fixed time is 5 seconds, 10 seconds, 3 minutes or 5 minutes etc., in this no limit.Generally speaking, through repeated execution of steps S100 repeatedly to step S102, the value of SPC can be adjusted to gradually in the scope of value of MPC, and the quantity of the resource using information that guarantee resource information acquisition server gathers etc. are all in the controlled scope of cloud computing, in this way, effectively avoided the problem of the I/O mouth bottleneck that the number of node too much causes.

The information processing method of the resource information acquisition server of the application's cloud computing is carrying out in the process of resource information collection, detect the SPC of self, and judge according to the value of SPC whether the ability of self shared cloud computing exceedes the value of default MPC, produce and whether report reference information to send to resource information to gather client according to judged result, finally can be by whether reporting reference information restriction resource information to gather the quantity of the resource using information that client reports.The application has solved in prior art effectively due to the increase of number of nodes, causes the problem of the I/O mouth bottleneck of resource information acquisition server.

Refer to Fig. 2, Fig. 2 is the schematic flow sheet of information processing method second execution mode of the resource information acquisition server of the application's cloud computing, in the present embodiment, the information processing method of the resource information acquisition server of cloud computing includes but not limited to following steps.

Step S200, resource information acquisition server obtains the current disposal ability information of self.

Step S201, more current disposal ability and default maximum processing capability, produce comparative result, and produce and whether report reference information accordingly according to comparative result.

Whether step S202, will report reference information to send to resource information to gather client.

Step S200 refers to the associated description of execution mode above to step S202, in the scope of understanding, does not repeat the art personnel.

Step S203, reads the resource using information that resource information gathers client collection and reports, and resource using information is that resource information gathers client according to the information that whether reports reference information to report.

Resource information acquisition server is in the process of resource using information that reads node, due to the number of node too much and/or the problem of I/O bottleneck, may cause resource information acquisition server to read in time or lose the resource information of needing processing badly and gather the resource using information of client.In order to solve this technical problem, in step S203, present embodiment gathers the resource information of needing processing badly client and whether reports the corresponding setting of reference information, by whether reporting the effect of reference information, can limit resource information collection client and meet the resource using information that just can report corresponding node under the condition that whether reports reference information, make the resource information acquisition server can be in the situation that MPC is certain, can read in time the resource using information that meets the node that whether reports reference information, in order to node being carried out to the processes such as follow-up scheduling.For example, if some specific node (1,3,5 is specified in cloud computing ... or front 100 nodes) belong to priority level processing, when resource information acquisition server is during in busy excess load, the resource using information of the node of this part priority treatment can be only read, and the resource using information of this part node can be effectively prevented from reading in time or having lost.Certainly, whether reporting reference information can be also to set by other conditions, in the time of busy excess load, can not lose or read not in time the resource using information of the node of needing processing badly as long as guarantee resource information acquisition server, in the scope of understanding the art personnel, do not repeat one by one.

Present embodiment can gather the resource using information that client reports according to the part resource information that whether reports reference information preferentially to read to need badly processing.The application had both avoided the problem of the I/O bottleneck of resource information acquisition server effectively, the problem that can also avoid resource information acquisition server to read in time or lose the resource using information of the resource information collection client of needing processing badly.

Please further consult Fig. 3, Fig. 3 is the schematic flow sheet of information processing method the 3rd execution mode of the resource information acquisition server of the application's cloud computing, in the present embodiment, the information processing method of the resource information acquisition server of cloud computing includes but not limited to following steps.

Step S300, current parallel when reading resource information and gathering the resource using information that client reports, corresponding disposal ability information that resource information acquisition server obtains self.

Step S301, according to the pre-configured more current disposal ability of default maximum processing capability of giving self of cloud computing.

Step S302, in the time that default maximum processing capability is greater than current disposal ability, reducing default resource uses change threshold value whether to report reference information to generate, in the time that default maximum processing capability is less than current disposal ability, strengthens default resource and use change threshold value whether to report reference information to generate.

It should be noted that, in step S302, the default resource of present embodiment is used and changes threshold value with RCUL(Resource Changing Upper Limit) represent, be defined as the rate of change of the resource utilization of arbitrary node in predetermined time section, and resource information acquisition server can gather RCUL all resource informations of issuing a notice in clients in the mode of broadcast.For instance, a certain node is at t ₁time resource utilization be 50%, at t ₂time resource utilization be 54%, the rate of change of its resource utilization is 0.04; Furthermore, if resource information acquisition server reads SPC while being less than MPC, it judges that self is in more idle state, can reduce RCUL so that the less node of the rate of change of resource utilization also can report the resource using information of self, monitor and scheduling etc. in order to cloud computing; And if resource information acquisition server reads SPC while being greater than MPC, it judges self state in busier excess load, need corresponding increasing RCUL only to allow the larger node of rate of change of resource utilization to report self resource using information, then it is monitored and scheduling etc.Be not difficult to find out, by setting the mode of RCUL, not only can limit resource information and gather the quantity that client reports, can also further guarantee when resource information acquisition server is during in busy or excess load, priority treatment meets the resource using information of the node of RCUL, and the larger node of the rate of change of this part resource utilization is monitored and scheduling etc., so that the utilance of the system resource of cloud computing is more optimized.

Whether step S303, will report reference information to send to resource information to gather client.

Step S300 refers to the associated description of one or more execution modes above to step S303, in the scope of understanding, does not repeat the art personnel.

Step S304, read resource information and gather client collection the resource using information that reports, resource using information be resource information gather after the resource using information that client collects node, by the dynamic resource utilization rate difference calculating according to resource using information with whether report resource in reference information to use to change threshold and dynamic resource utilization rate difference to be more than or equal to resource to use the resource using information just reporting while changing threshold value.

In step S304, it is the rate of change of resource utilization that the resource using information that resource information collection client need to collect node according to it calculates dynamic resource utilization rate difference DELTA RCUL(), and the resource using information just reporting in the time that dynamic resource utilization rate difference DELTA RCUL is more than or equal to RCUL.In other words, resource information collection client only reports the resource using information of the node that rate of change is larger.For example, the resource utilization of some nodes of cloud computing in predetermined time section jumps to 60% from 2%, its dynamic resource utilization rate difference DELTA RCUL be 0.58 or-0.58(for convenience of describe, present embodiment is using the larger value of resource utilization as minuend, be that dynamic resource utilization rate difference DELTA RCUL all gets positive number), that is to say the state of this node resource of explanation in low utilization; And if the RCUL setting according to the resource of cloud computing or COS be initially set to 0.2, be that dynamic resource utilization rate difference 0.58 is greater than 0.2 of RCUL, the dynamic resource utilization rate difference DELTA RCUL of this node meets the condition reporting, so its corresponding resource information gathers client, the resource using information of this node is reported to resource information acquisition server; After resource information acquisition server reads its resource using information, can monitor or trend analysis etc. this node, for example control service or the lower electricity shutdown that the corresponding host resource of this node etc. carries out other and save the energy etc. to reduce number of nodes, in the scope of understanding the art personnel, do not repeat.Certainly, in other embodiments, also can only read the resource information that dynamic resource utilization rate difference DELTA RCUL is greater than RCUL and gather the resource using information that reports of client, in this no limit.

Present embodiment is than last execution mode, by setting the mode of RCUL, busy at resource information acquisition server, when excess load, carry out priority treatment without the specific node of setting according to cloud computing, and only need to read dynamic resource utilization rate difference DELTA RCUL and meet the resource using information of the node of the condition of RCUL, thereby intelligently the larger node of dynamic resource utilization rate difference DELTA RCUL is carried out to priority treatment, make the node resource of cloud computing obtain more effectively monitoring, analysis and scheduling etc., make the node resource of cloud computing realize rapidly load balancing.

Refer to Fig. 4, Fig. 4 is the schematic flow sheet of information processing method the 4th execution mode of the resource information acquisition server of the application's cloud computing, in the present embodiment, the information processing method of the resource information acquisition server of cloud computing includes but not limited to following steps.
