Hi everyone,
I was wondering if anyone has extracted the trace after a crash dump. The
following menuconfig option exists :
config LTT_VMCORE
bool "Support trace extraction from crash dump"
depends on LTT
default y
help
If you enable this option, the Linux Trace Toolkit Tracer will
support extacting ltt log from vmcore, which can be generated with
kdump or LKCD tools.
Special crash extension should be used to extract ltt buffers.
Now I understand it enables some code to enable extraction of trace from
crash dump. What are steps involved to get the trace after a crash ?
Regards
Gaurav
