The EMS 105 is configured to perform error, configuration, accounting, performance, and security (Fault, Configuration, Accounting, Performance and Security, FCAPS) management on one or more VNFs.

The VNF 106 corresponds to a PNF (Physical Network Function) in a traditional non-virtualized network, such as a virtualized EPC (Evolved Packet Core) node, to implement a specific network function. A VNF can be composed of multiple lower-level components. Therefore, a VNF can be deployed on multiple virtual machines (English: Virtual Machine, VM for short), and each VM controls a VNF component.

NFVI107, which consists of hardware resources, virtual resources, and virtual layers, is the entity that provides the required virtual resources.

In this embodiment, the fault information acquiring device may be the NFVO 101 or the VNFM 102 in the NFV system 10, which is of course only an example. Specifically, the structure of the fault information acquiring device is as shown in FIG. 2, and the fault information acquiring device 20 includes: a query management module 201 and an information acquiring module 202.

The query management module 201 is configured to obtain query information, where the query information is used to indicate that the fault information is obtained, and the query information is further used to indicate the identifier of the object to which the fault information belongs, the type of the fault information, and the time period to which the fault information belongs. At least one of the faults; the fault information is used for fault analysis.

The information obtaining module 202 is configured to obtain fault information according to the query information acquired by the query management module 201.

For example, the NFVO 101 or the VNFM 102 can collect fault information through a Representational State Transfer/Simple Network Management Protocol (REST/SNMP) interface provided by the VIM 103.

Optionally, the fault information acquiring device further includes a transmission module 203, configured to send the fault information acquired by the information acquiring module 202 to the fault management device. For example, NFVO 101 or VNFM 102 can send fault information to OSS 104 or EMS 105.

In the first application scenario, as shown in FIG. 3, FIG. 3 shows the structure of another fault information acquiring device. For the process of acquiring a fault information, there is usually a start time and an end time, that is, an acquisition start. The fault information in the time period from the time to the end time, that is, the query information may include the time period to which the fault information belongs, that is, the fault information in the time period is acquired, and of course, the time period to which the fault information belongs may also be advanced. The parameter is set, so that the query information does not need to include the parameter of the time period to which the fault information belongs, but can indicate that the fault information is obtained during the time period to which the fault information belongs.

Further, the fault information acquiring device may further include a task management module 204, configured to store the collection task, monitor the stored collection task, and trigger the collection task to start execution, specifically for acquiring task information, and the task information is used to indicate the preset. The query information is obtained at the moment and the fault information is obtained according to the query information, and the preset time is greater than or equal to the end time of the time period to which the fault information belongs. It should be noted that the task information may be generated by the fault information acquiring device, or may be sent by other devices. In the present invention, an acquisition task is a complete process of acquiring fault information once, once The process of obtaining the fault information may include obtaining the query information and obtaining the fault information according to the query information. Here, it should be noted that the one-time collection task does not include the process of sending the acquired fault information to the fault management device.

Based on the foregoing first application scenario, for the query information, three acquisition modes are listed here. The first mode may be generated according to the user indication. When the fault information needs to be acquired, the user may input a control command to trigger the query management module 201. The query information is generated; the second method can preset the period and periodically generate the query information. The first method is flexible and can obtain fault information according to user requirements. The second method reduces user operations and can periodically obtain fault information. The NFV system can be monitored for a long time by periodically obtaining fault information. The method of triggering the collection task is to trigger the collection task at the end of each period to obtain the fault information of the previous period. Of course, the two ways of triggering the collection task can be controlled by the task management module 204 described above. In addition, the third mode can receive the query information sent by other devices, and send the fault information to the fault management device after obtaining the fault information.

Optionally, the fault information obtaining device may further include an object management module 205, configured to store and update a state of the at least one object, and configured to determine, when the query information includes an identifier of the object to which the fault information belongs, determine an object to which the fault information belongs.

For example, the preset alarm information processing rule may be used to indicate how to process multiple alarm information. Specifically, for example, the alarm information A is caused by the alarm information B. The alarm information A and B have parent-child correlation. If two alarms A and B are obtained, only the alarm information A can be retained according to the correlation between the parent and the child.

The information processing sub-module 2022 is configured to invoke the preset information processing rule stored by the rule management sub-module 2023 to process the information collected by the information collection sub-module 2021 according to the preset information processing rule to generate fault information.

Here, it should be noted that the conversion to the preset format is because the information format and the object model of different systems in the NFV system are likely to be different from each other. Therefore, the collected information needs to be converted into a preset format after the information is collected. The collected information is in accordance with the format of the fault information acquiring device, and the preset format is a format used by the fault information acquiring device, and may include at least one of an information format supported by the fault information acquiring device and an object model supported by the fault information acquiring device.

After the two types of information are obtained, the fault information acquiring device sends the two types of fault information obtained to the subscription device. Of course, one or more subscriptions may be obtained. The fault information of the object may also be subscribed to the fault information of a certain period of time, and the manner of the subscription may be set by itself, which is not limited by the present invention.
