The tracing system really looks at the Linux kernel as a > whole, and for the most part ignores things like name spaces. We started by trying to support perf inside a container and currently we are exploring approaches to support function tracing inside a container. One approach that we are thinking/working is on the lines of patch 1/3. For example, filtering events based on the namespace in which the trace file is read. We are trying to understand the ftrace implementation and hence not sure if this is feasible. We would be happy to explore if you have any suggestions/feedback on supporting function tracing inside a container. > > Can a container have its own function tracing? Sorry, I didn't understand that. Do you mean to have a separate per-container trace files? Regards, Aravinda > > -- Steve > -- Regards, Aravinda
