Thanks a lot. Pierre.

Do you mean a feature similar/equal to Flight Recorder mode is already
implemented in UST ?

No. My email described how to implement support for flight recorder in UST.


Do I need to have some third party application or daemon running in the
background to collect buffer data such as crash ?

No. UST provides a daemon. This daemon already supports crash recovery. This daemon could be enhanced to support flight recorder.

Thank you !!

        Hello Mathieu,

        I want UST (LTT User-Space Tracing) with Flight Recorder
        integration.
        What will be the major steps involved here to complete the UST
        with FR
        support ?


    Hi Srikanth,

    One would need to modify ustd to take command line arguments to do a
    one-shot collection of the buffers of a process on demand. The
    overwrite mode for the buffers is already implemented, see the
    UST_OVERWRITE environment variable.
