Processing system is held to handle the parameter of task ability.
It is understood that server can obtain the currency of the pressure parameter of back-end processing system, specifically, can be with
It is that back-end processing system is transmitted directly to server；Can also be that server actively stores pressure parameter from back-end processing system
The position of currency is directly obtained；Another equipment, the equipment can also be set between back-end processing system and server
To be obtained from back-end processing system after pressure parameter currency, server is transmitted to, back-end processing system achieved above
What the mode of pressure parameter currency was merely exemplary, do not constitute the specific restriction to the embodiment of the present invention.
It should be noted that pressure parameter is the parameter that task ability is handled for reacting back-end processing system, server
Obtain the currency of pressure parameter, you can know that back-end processing system handles the situation of task at present.Specifically, pressure parameter can
Think response time, the instantaneous number of concurrent of request, the back-end processing of the back-end processing system of the back-end processing system
At least one of the memory usage of system, cpu load value of the back-end processing system.
It is understood that the cpu load value and the memory usage of back-end processing system of back-end processing system, are reactions
The running status of back-end processing system itself, in the case that back-end processing system overloads, cpu load value and memory usage meeting
Very big, exemplary, cpu load value can be expressed as a percentage, at a time, the cpu load value of back-end processing system
Currency is that the currency of the memory usage of 75%, back-end processing system is 60%.The response time energy of back-end processing system
Enough reaction back-end processing system from request is received to time for handling it of request, the request of back-end processing system is instantaneous simultaneously
