[lttng-dev] How to disable an event that's been enabled by a wildcard selection or -a?

[Ikaheimonen, JP]

Consider the following scenario.
I want to write a script that traces all UST tracepoints of a given application. I have no idea what the names of these tracepoints are. Also, I know that the application uses a library that contains some tracepoints I am not interested about. Now I want to trace all UST tracepoints except the ones I already know about. Is this possible with the lttng commands?

If I enable all tracepoints with "lttng enable-event -u -a" I get all events, even those I do not want. I've tried using "lttng disable-event", and "lttng enable-event" with a filter, but I cannot seem to be able to get rid of the specific events.

Thank you,
