Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.

It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.

In view of the above, a first aspect of the embodiments of the present invention provides a data aggregation device for a monitoring system. As shown in fig. 1, the data aggregation device specifically includes: a rule engine module 110, a data aggregation processing module 120, and a storage module 130, wherein:

the rule engine module 110 is used to configure data aggregation rules.

By setting the convergence channel, different dimensionalities of data can be processed, and cooperative data processing can also be performed by combining processing results of a plurality of different convergence channels;

the data aggregation processing module 120 includes a plurality of data aggregation channels, and the data aggregation processing module 120 is configured to acquire data, transmit the data to a corresponding data aggregation channel, process the data based on a data aggregation rule configured by the rule engine module 110, and output an aggregation result.

By setting the convergence channel, different dimensionalities of data can be processed.

The data aggregation processing module 120 is further configured to determine whether an aggregation result output by the corresponding data aggregation channel has a dependency relationship with data transmitted to the other data aggregation channels, and store the aggregation result in a cache layer or a persistent layer of the storage module 130 based on the determination result.

The storage module is divided into the cache layer and the persistence layer, so that the processed data and the convergence result dependent data are cached and stored persistently according to the data convergence processing result, and the efficiency of data convergence processing is improved.

For a better understanding of the embodiments of the present invention, the following data aggregation scenario of CPU utilization is illustrated.

A data aggregation Rule is configured through the Rule engine module 110, the Rule is to average 60 times of input data, and the Rule is named Rule 1;

two data aggregation channels are created by the data aggregation processing module 120.

The data aggregation channel 1 is named Pipeline1, data input is set to be 1 parameter, parameter values are CPU utilization rate performance data of a receiving module, and an aggregation Rule with the aggregation Rule name of Rule1 is associated;

the data aggregation channel 2 is named Pipeline2, the data input is set to be 1 parameter, the parameter value is the output value of Pipeline1, and the associated aggregation Rule is the aggregation Rule of Rule 1.

After the data aggregation module 120 obtains the CPU utilization data, the CPU utilization data is transmitted to a data aggregation channel named Pipeline1, and the Rule engine module 110 associates the aggregation Rule1, so that after 60 times of transmission of the CPU utilization data to the data aggregation channel, the data aggregation channel obtains an aggregation result and outputs the aggregation result.

In the second-level monitoring system, the reporting frequency of data is 1 second and 1 time, and the average utilization rate of the CPU in the minute level can be obtained through the aggregation configuration.

The data aggregation processing module 120 determines that the aggregation output result of the data aggregation channel 1 is the dependent data of the data aggregation channel 2, and thus stores the aggregation result in the cache layer of the storage module 130 for standby.

The data aggregation module 120 obtains the average usage rate of the CPU at the minute level output by the data aggregation channel 1, transmits the average usage rate of the CPU at the minute level to the data aggregation channel named Pipeline2, and associates the aggregation Rule1 with the Rule engine module 110, so that after 60-time transmission of the CPU usage rate data at the minute level to the data aggregation channel 2, the data aggregation channel 2 obtains an aggregation result and outputs the aggregation result, that is, the average usage rate aggregation result of the CPU at the hour level is obtained.

The data aggregation module 120 obtains data from two sources, one is obtained from the monitoring system, for example, the CPU utilization data transmitted to the data aggregation channel Pipeline1 in the above example; one is the aggregate result output by the other data aggregation channels, for example, the average of the 60 CPU utilization data output by the data aggregation channel Pipeline1 in the above example.

For aggregation results with dependency relationship, the aggregation results may be cached in the cache layer of the storage module 130 first, and obtained from the cache layer when waiting for the data aggregation processing module 120 to use; or directly output to the corresponding data gathering channel, and use after the data gathering channel triggers the associated rule.

By the embodiment of the invention, when data processing is converged, the data convergence rule and the data convergence channel can be conveniently and dynamically adjusted, the convergence processing of the data is accelerated, and the data convergence efficiency is improved.

The storage module for storing data generally selects a database, if the data is stored in the database for storage after being sorted, the data is inquired from the database when the data is required to be used, the time for inquiring the data is required, and particularly, the data acquisition time is prolonged when the data stored in the database is large or the data inquiry operation is frequently performed, so that the data is reduced. Therefore, the storage modules are layered, and two databases are established, wherein one database is used as a cache layer of the cache module, and the other database is used as a persistence layer of the storage module. The data to be used or the convergence result is changed by the cache layer, so that the query to the database can be reduced, the acquisition of the data is accelerated, and the data convergence efficiency is improved.
