Hi All, I have a few questions regarding the Session Daemon. 1. Is it possible to list all available events for a given PID?
Not yet.
2. Is it possible to list all enabled events for a given PID?
Not yet.
3. If the answer to above is Yes, could you please give me with the signutures of those functions (if you have them)?
The goal is to move "libustctl" from the UST git tree to lttng-tools tree and use that API to do all user-space tracing commands. Those functions interacting with the user-space tracer are in the lttng-tools git tree at "ltt-sessiond/ust-ctl.c". However, for now, there is none for listing events/markers.
4. I looked at the current version of Userspace Tracer-UST but I did not find those functionalities although list-trace-events for a given PID was available in an older version. Is that work still in progress?
Normally, "list-markers" should give you all markers or/and tracepoints and the state (0: disable, 1: enable).
"list-trace-events" is only to list "TRACE_EVENT" which are not yet fully implemented and right now are only dummy printf.
As soon as UST is modified to support the new session daemon (of lttng-tools repo), listing events for a given PID will be available upon the UST release.
Don't hesitate for any other questions. Cheers! David
