Example method may include：
Step 101, the history resource information of collecting device, the load characteristic and frequency of equipment are determined according to history resource information
Rate adjustable range.
The acquisition of the device periodically history resource information of itself, the history resource information are equipment before acquiring the moment
First time period in history resource information, such as history resource information of the equipment in 5 minutes before acquiring the moment.It goes through
History resource information includes any one following information or much information combination：The status information of equipment CPU, the memory letter of equipment
Breath, input/output I/O read and write rates and network state information.
Wherein, the status information of CPU include the C-State maximum depth values of CPU, CPU P-State adjust strategy, CPU
Frequency values and CPU utilization rate, wherein the P-State of CPU, which adjusts strategy and generally comprises following three kinds, adjusts strategy：Section
Strategy can be adjusted（power save）, optimum performance strategy（performance）, automatic adjusument strategy.When business is to processing
The processing speed of device require it is low in the case of, the P-State of CPU may be selected, and to adjust strategy be Energy Saving Strategy, at this moment the frequency of CPU
Low-power consumption is also small.Optimum performance strategy is selected, at this moment to improve the processing capacity of CPU for high performance calculating business
The frequency highest of CPU, performance is best, certain power consumption also highest.Automatic adjusument strategy can be according to adjusting CPU the case where business
Working frequency.The memory information of equipment is the utilization rate of memory, input/output（Input/Output, abbreviation I/O）Read and write rate
The frequent degree for indicating read-write operation, to needing the frequent business for outputting and inputting information, I/O read and write rates are high, network-like
State information is primarily referred to as network bandwidth.
After getting the history resource information of equipment, the load characteristic of equipment is determined according to history resource information, is loaded
Characteristic includes computation-intensive load, the load of I/O intensities and normal load etc..If utilization rate and the memory profit of the CPU of equipment
All it is higher than the threshold value of setting with rate, it is determined that equipment loads for computation-intensive, wherein the utilization rate of CPU refers at first
Between average utilization in section, memory usage also refers to the average utilization in first time period.If the profit of the CPU of equipment
It is below the threshold value set with rate and memory usage, but I/O read and write rates are quickly, and network bandwidth occupies greatly, also may be used certainly
An I/O read and write rates threshold value and bandwidth threshold is arranged, set when getting the I/O read and write rates in first time period and being more than
Fixed I/O read and write rate threshold values, and network bandwidth is also greater than bandwidth threshold, it is determined that the loadtype of equipment is I/O intensive
Load.If the utilization rate and memory usage of the CPU of equipment are both less than given threshold, I/O read and write rates and network bandwidth are also small
In given threshold, it is determined that the cover type of equipment is normal load.
After determining load characteristic according to history resource information, the equipment can also be determined according to history resource information
The frequency-tuning range of CPU specifically when equipment support CPU automatic frequencies adjusting, is set according to the determination of history resource information first
Standby mean frequency value, can by each frequency values of the CPU in the collected first time period of equipment make and, then averaged obtains
To the mean frequency value of equipment.After obtaining mean frequency value, the frequency tune of equipment is determined according to mean frequency value and history resource information
Adjusting range, specifically, after determining mean frequency value, according to mean frequency value and to collect each frequency values in history resource information true
Determine the mean square deviation of cpu frequency, if mean square deviation is bigger, illustrate that the fluctuation range of frequency is bigger, is determined according to the size of fluctuation range
The fluctuation range of frequency, such as mean frequency value are 1.5GHZ, and fluctuation range is little, it is determined that frequency-tuning range is
1.32GHZ to 1.78HZ, if frequency-tuning range is big, it is determined that frequency-tuning range is 1.15GHZ to 1.85GHZ.Alternatively, working as
It determines that frequency-tuning range is very big, then can determine minimum value that fluctuation range is collected each frequency values to maximum value.
According to the resource mean value of equipment in first time period and the frequency-tuning range of CPU, second time period can be estimated
Interior resource requirement, to acquire the moment as separation, first time period is a period of time before acquiring the moment, second time period
Refer to 5 minutes before the acquisition moment for a period of time after the acquisition moment, such as first time period, the second segment time refers to acquisition
5 minutes after moment, according to first 5 minutes history resource informations, resource requirement in 5 minutes after estimation.
If equipment does not support CPU automatic frequencies to adjust, according to the CPU for the equipment that the history resource information of equipment is determined
Frequency-tuning range be fixed frequency grade.It specifically, can be according to the frequency level of collected equipment and the utilization rate of CPU
The frequency level for determining equipment, when frequency of the equipment in first time period is very high, but the utilization rate of CPU is but very low, explanation
Apparatus of load characteristic is I/O intensive, of less demanding to the processing capacity of CPU, therefore, it is necessary to reduce the frequency level of equipment,
To reduce the power consumption of equipment.When frequency of the equipment in first time period is very low, but the utilization rate of CPU is very high, illustrates equipment
Load characteristic is computation-intensive, requires height to the processing capacity of CPU, therefore, it is necessary to improve the frequency level of equipment.
Step 102, the load characteristic according to equipment, selection and the matched processor state adjustable strategies of load characteristic.
After determining apparatus of load characteristic, according to the state adjustable strategies of apparatus of load characteristic selection processor.It is existing
In technology, most equipment supports automatic frequency adjustment, system kernel meeting adjust automatically frequency, for this kind of equipment, processor
Adjustable strategies include：The C-State maximum depth values of CPU, the P-State of CPU adjust strategy.Such as it is operated in typical Linux
In system, user is used simultaneously by system bios or the available C-State depth capacitys of kernel start-up parameter initialization system
CPU-Freq modules, setting P-State adjust strategy and adjustable range.Xen Hypervisor then provide its included power supply
Management tool xenpm（Xen power management）C-State depth capacitys, the P-State adjusting strategies of CPU is arranged
And the adjustable range of P-State.Equipment for not supporting automatic frequency to adjust, processor adjustable strategies only include：CPU's
C-State maximum depth values.
When load characteristic be computation-intensive load, then according to load characteristic load to computing capability require height, if
The maximum depth value of C-State is set, and selects P-State to adjust strategy and adjusts strategy for optimum performance, when CPU is operated in most preferably
When property regulation strategy, the frequency of CPU is maximum, and performance is best at this time.When load characteristic is that I/O intensities load, according to negative
It carries characteristic and understands that load is of less demanding to computing capability, the maximum depth value of C-State is set, and P-State is selected to adjust plan
Slightly energy saving adjusting strategy, common I/O intensities are loaded such as Web service, mail server business since it is to processing
Device demand is relatively low, and the energy saving strategy that adjusts can be selected to adjust strategy as the P-State of CPU.It is optional for other load characteristics
The P-State that automatic adjusument strategy is selected as CPU adjusts strategy.
Step 103, according to the state of processor state adjustable strategies and the CPU of the frequency-tuning range adjusting device of equipment
Parameter.
When equipment support automatic frequency adjust, the state parameter of CPU refer specifically to the C-State of CPU maximum depth value,
The adjusting strategy of the P-State of CPU, the frequency level of CPU, model is adjusted according to the frequency of processor state adjustable strategies and equipment
Enclose the state parameter of the CPU of adjusting device specifically, by the C-State maximum depth values of CPU, P-State adjust strategy and
Frequency-tuning range is sent to system kernel, adjusts the current C- of CPU according to C-State maximum depth values by system kernel
State maximum depth values, and according to the working frequency of P-State adjustings strategy and frequency-tuning range adjustment CPU, such as when
When CPU is operated in optimum performance and adjusts strategy pattern, highest frequency 2.4GHZ, the frequency-tuning range determined is
1.55GHZ to 1.92GHZ, the frequency range determined is a successive value, and the frequency of CPU real works is one discrete
Value, also referred to as frequency level, such as CPU can only operate in 1.4GHZ, 1.5GHZ, 1.6GHZ, 1.7GHZ, 1.8GHZ these frequencies
In grade, therefore, it is necessary to carry out a mapping to the frequency-tuning range determined, fluctuation range is mapped to actual frequency
In grade, for example, 1.55GHZ to 1.92GHZ fluctuation range mapping after frequency level be 1.6GHZ, 1.7GHZ, 1.8GHZ,
This four frequency levels of 1.9GHZ.System kernel according to the current frequency and frequency-tuning range of CPU, by cpu frequency from
2.4GHZ is reduced to any one in 1.6GHZ, 1.7GHZ, 1.8GHZ, 1.9GHZ, and the range of CPU adjustment is minimum to be cannot be below
1.6GHZ can not be higher than 1.9GHZ, can only be adjusted to the frequency of CPU within the scope of this.
As the maximum depth value that equipment does not support automatic frequency to adjust, and the state parameter of CPU is the C-State of CPU, CPU
Frequency level, according to the state parameter of processor state adjustable strategies and the CPU of the frequency-tuning range adjusting device of equipment
Specifically, the state of CPU is adjusted according to the maximum depth value of the C-State of CPU and the frequency level determined, by working as CPU
The maximum depth value of preceding C-State is adjusted to the maximum depth value of the C-State determined, and CPU current frequencies are adjusted to
The frequency level determined.
The present embodiment determines the load characteristic of equipment according to history resource information by collecting device history resource information
With the frequency-tuning range of CPU, matched processor state adjustable strategies are then selected according to load characteristic, finally according to processing
The state of device adjustable strategies and frequency-tuning range adjustment CPU, since processor adjustable strategies and frequency-tuning range are bases
What the history resource information of equipment determined, so as to timely adjust the state parameter of CPU, optimization according to the variation of load
