Description

CROSS REFERENCE TO RELATED APPLICATIONS This is a continuation of International Patent Application No. PCT/CN2020/100932, filed on Jul. 8, 2020, which claims priority to Chinese Patent Application No. 201910730071.X, filed on Aug. 8, 2019. The disclosures of the aforementioned applications are hereby incorporated by reference in their entireties. TECHNICAL FIELD This disclosure relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for obtaining management data. BACKGROUND As various communications services are emerging, different communications services have significantly different requirements for network performance. A network slice is introduced into a 5th generation (5G) communications system to meet differentiated requirements of the different communications services for network performance. The network slice refers to customizing a logical network on a physical or virtual network infrastructure, according to different service requirements. The network slice may be a complete end-to-end network including a terminal device, an access network, a transmission network, a core network, and an application server, and can provide a complete communication service. Generally, different network slices have different network performance requirements. After an operator divides a communications network into a series of network slices, the network slices are logically isolated from each other and have different network features. Different customers can subscribe to a plurality of network slices from the operator, in this way, a physical network of the operator can meet differentiated requirements of different applications for network. Because a network slice instance is a relatively isolated logical network, the operator usually opens a part of management data to a tenant (for example, another operator) based on a service requirement. For example, the operator allows the tenant to obtain part of network performance results or part of alarm information, such that the tenant learns a network slice running status and facilitates the tenant to develop its own business. Currently, there is no good method to control the tenant to obtain management data within a reasonable range. SUMMARY This disclosure provides a method and apparatus for obtaining management data, to enable a tenant to obtain management data within a proper range. According to a first aspect, this disclosure provides a method for obtaining management data. The method includes: A first network element receives a request message from a second network element, where the request message indicates a tenant identifier and at least one managed object instance, and the tenant identifier corresponds to at least one network slice service identifier; the first network element determines a first managed object instance in the at least one managed object instance based on the network slice service identifier, where the second network element has permission to obtain management data of the first managed object instance; the first network element obtains management data corresponding to the network slice service identifier from the first managed object instance; and the first network element sends the obtained management data to the second network element. According to this solution, upon requesting to obtain management data, the second network element obtains management data at a network slice service identifier granularity, to be more specific, obtains management data related to a slice service subscribed by a tenant, such that data isolation between different tenants is implemented and data security and privacy is facilitated. In a possible implementation method, that the first network element determines a first managed object instance in the at least one managed object instance based on the network slice service identifier includes: For any one managed object instance in the at least one managed object instance, if the first network element determines that an attribute of the any one managed object instance includes the network slice service identifier, determining that the any one managed object instance is the first managed object instance. In a possible implementation method, the first network element obtains the attribute of each managed object instance in the at least one managed object instance from a database. In a possible implementation method, the tenant identifier is the at least one network slice service identifier. Alternatively, the first network element obtains the at least one network slice service identifier corresponding to the tenant identifier based on the tenant identifier from a third network element, where the third network element is the first network element, the second network element, or the database. In a possible implementation method, the at least one managed object instance includes one or more of the following items: a network function, a network slice instance, or a subnet slice i
