1. A processor-implemented method for analyzing data processing, the processor-implemented method comprising: acquiring, by one or more processors, dependency metadata, wherein the dependency metadata is used for representing dependency on data among at least two components of an application, and wherein said acquiring dependency metadata comprises: acquiring, by one or more processors, a profile of an application instance from a cloud platform; and searching, by one or more processors, a local environment based on the profile to obtain at least part of the dependency metadata; acquiring, by one or more processors, error information and data output, wherein the error information is used for describing errors that occur while running the application, and wherein the data output includes data output by said at least two components while running the application; analyzing, by one or more processors and based on the error information, dependency metadata and data output relevant to the error information; and providing, by one or more processors, an analysis result, wherein the analysis result includes at least one of: a reason why an error occurs, a prompt for an error correction method, a relevant dependency metadata leading to an occurrence of an error, and relevant data output leading to an occurrence of an error.
