One aspect describes a method, a computer system, and a computer-readable medium that facilitate the injection of customized YANG views to a network device. A network device runs a Yet Another Next Generation (YANG) server to provide telemetry data associated with the network device, the telemetry data defined by a YANG model. In response to receiving, from a remote client, a customized YANG view file, the YANG server determines whether the customized YANG view file contains an error. In response to determining that the customized YANG view file does not contain an error, the YANG server activates the customized YANG view file without upgrading the network device's firmware and rebooting the network device. The YANG server receives a query from the remote client specifying the customized YANG view file, gathers telemetry data based on the customized YANG view file, and returns the gathered telemetry data to the remote client.

A system receives a request for data stored in an OVSDB database server, wherein the request comprises a JSON RPC request. In response to the request, the system initiates a proxy session by: creating a first communication session between the requesting entity and a proxy daemon, wherein the request indicates a first version corresponding to the first communication session; and creating a second communication session between the proxy daemon and the database server, wherein the second communication session is associated with a second version corresponding to a model used by the database server. The system determines that the first version does not match the second version. The system extracts, from the request, a JSON RPC method and determines that the method requires translation. The system performs, based on the first and second version, translation of a payload of the request, and sends the translated payload to the database server.
