Load judgment system and method for report sampling system

Abstract

The invention provides a load judgment system for a report sampling system and a load judgment method for the report sampling system. The method comprises the following steps of: setting four threshold values to be taken as judgment basis loaded by a system, wherein the four threshold values are respectively the lowest central processing unit (CPU) occupancy, the highest CPU occupancy, the lowest buffer zone occupancy and the highest buffer zone occupancy. The method of the load judgment system for judging the load of the system comprises the following steps of: firstly, obtaining the current CPU occupancy and buffer zone occupancy; regarding as the load to be lighter only when the current CPU occupancy is lower than the lowest CPU occupancy and the current buffer zone occupancy is lower than the lowest buffer zone occupancy, so that the sampling proportion of the system needs to be improved; regarding as the load to be heavier only when the current CPU occupancy is higher than the highest CPU occupancy and the current buffer zone occupancy is higher than the highest buffer zone occupancy, so that the sampling proportion of the system needs to be reduced; and keeping the sampling proportion constant under the other conditions. After the load judgment system for the report sampling system and the load judgment method for the report sampling system are used, the exact load judgment of the system can be realized, and the sampling proportion of the report can be stably controlled.

Description

technical field [0001] The invention belongs to the field of network data processing, and in particular relates to a load judging system and method of a message sampling system. Background technique [0002] In the network data analysis system, not all the data is often analyzed, but according to the current load of the system, according to a certain proportion, a part of the packets are extracted from all the traffic for analysis. When the system load is light, the packets are increased. The sampling ratio, when the load is heavy, the sampling ratio is reduced. [0003] In the prior art solution, the judgment of the current load of the system is based on the occupation of the CPU or the occupation of the message buffer, and the percentage of the current CPU occupation or the occupation of the message buffer is taken as the system load. [0004] In the message sampling system, due to the uncertainty of the input data, both the CPU and the buffer often affect the overall loa...

Problems solved by technology

[0004] In the message sampling system, due to the uncertainty of the input data, both the CPU and the buffer often affect the overall load of the system. Sometimes the CPU load is heavy and the buffer is empty, and sometimes the buffer is full and the CPU load is light. , and taking the CPU load as the system load will lead to the problem that the buffer resources cannot be fully utilized. Taking the buffer load as the system load will not truly reflect the current CPU usage, but will also lead to a waste of CPU resources; both cases will The packet sampling ratio is adjusted frequently, and the packets cannot be sampled smoothly.
