[lttng-dev] Can tracepoint be listed before app registered?

[zlynus]

Hi,
Sorry to bother you guys. The lttng-tool man page dosen't make it clear that when the tracepoints of user-space application can be listed. So I did a little test. As far as I can tell ,the tracepoint information is only available during the application is running. 


So is it possible that the tracepoint can be available *before* app get running, specifically, before enable-event subcommand? I think it can be quite convenient to output the list when specify which events to trace. If it is not for now,
maybe it's a feature worth working on. My idea is lttng-tool could read tracer provider library and get the info,and  add a option after 'list' subcommand which let user specify the provider library to read. Just a personal opion from a new comer :-)


Best regards,
Lingyu Zhu
