I am really struggling trying to get user space tracing working predictably and consistently and would appreciate some help.
I created a trace event called kvm_server:new_connection_tracepoint (see attached), I then use lttng-gen-tp to generate the .c and .h files which I link to the program and call with tracepoint(kvm_server, new_connection_tracepoint, .................) This appears predictably in my traces However if I call my second tracepoint (see attached) tracepoint(resolution_management, resolution_management_tracepoint,.......) It never appears in any of the traces I can see no significant difference between the two definitions. I then created a third trace definition called simple_example (see attached) tracepoint(simple_example, simple_example_tracepoint, .....) This again appears in the trace I start the tracing using lttng enable-event -u -a # enable user-space tracing I then use babel trace to dump the trace, 'kvm_server' and 'simple_example' appear in the trace, resolution_management does not. Any idea why the resolution_management tracepoint does not appear in any traces or is there some way of debugging the tracecall macro itself? regards John ________________________________ This email and any files transmitted with it are confidential and are intended for the sole use of the individual to whom they are addressed.
