Example (b):
the system provides a method for reducing service level monitoring alarm error by depending on a transaction model and network layer indexes. The alarm misjudgment range of judgment is reduced as much as possible while the misalarm is reduced, and the overall accuracy of the alarm is ensured.
Referring to fig. 1, the method comprises the following steps:
step 1, network data acquisition: the system comprises a data acquisition module, a data transmission module and a data transmission module, wherein the data acquisition module is used for acquiring an original data packet, and outputting the original data packet as original network data with a fixed format;
and 2, data decoding: decoding the original data packet, fusing a service path diagram (transaction model), associating the original data with a service communication point, and generating a service data packet and a network data packet; inputting the original network data with the fixed format output in the step 1; the output is the decoded service data and the network event information with the transaction model.
Step 3, service data monitoring: receiving data and a model, monitoring whether the network state meets the analysis requirement and whether the service index reaches the standard, and generating an alarm event according to an alarm processing logic; inputting a transaction model configured for a user, a service data packet and a network event packet output in the step 2; the output of which is an alarm event.
Step 4, service analysis homepage: configuring a business service path graph, and displaying business indexes and alarm events; the input of the method is the alarm event output in the step 3. The service analysis homepage outputs a service path diagram as configuration and sends the configuration to the system for controlling data decoding and service data monitoring. In the service path diagram, the smallest unit is a specific service communication point in an actual scene.
As shown in fig. 2, the step 2 data decoding includes the following steps:
step 2.1: decoding a service protocol, namely generating service data after the original network data is decoded by the service protocol, and associating the service data with a service communication point in a model by combining a data model; the business data and the business communication points in the model are related as follows: and associating according to the source and destination ip addresses and ports configured by the service communication point and the configured service protocol message characteristics, wherein the service data obtained by decoding also has the dimensions, and the association of the service data and the communication point is realized by matching the dimensions.
Step 2.2: decoding a network protocol, generating a network event after original network data is decoded by the network protocol, associating the network event with a service communication point in a model by combining a data model, wherein the association of the network event and the service communication point in the model is as follows: and matching the source and destination ip addresses and ports in the network event according to the source and destination ip addresses and ports configured by the service communication point, and associating the network event with the service communication point.

Due to the fact that network environments of different sites are greatly different, parameter identification of network events is achieved through combination of two modes of manual configuration of initial parameters and machine learning, baseline indexes are generated through online operation for a period of time and serve as bases of final configuration, and complexity of manual intervention is reduced.
