Method and apparatus for retrieving time-based event data into unified activity hierarchy across process clusters

摘要

A method includes receiving notifications associated with batch execution instances executed by multiple devices. The notifications identify events occurring in an industrial process control and automation system. The method also includes creating a unique namespace for association with the notifications. The method further includes storing records identifying the notifications in a unified activity hierarchy based on the unique namespace. Creating the unique namespace could include creating an initial namespace using one or more fields associated with a parent process being executed. The parent process can activate a child process, and a namespace for the child process can contain the initial namespace and use one or more fields associated with the child process. The child process can activate a grand-child process, and a namespace for the grand-child process can contain the initial namespace and the namespace for the child process and use one or more fields associated with the grand-child process.
