Can you provide the output of:
babeltrace -o ctf-metadata /home/stjernstrom/lttng-traces/reg-20161006-130344
?
If you can share the content of your tracepoint header files, it
would also be useful.
Thanks,
Mathieu

Hi Simon,
Here's one of the pid's metadata files, it does look a bit suspicious
to my untrained eye. I've also enclosed the three tracepoint
definition files that are in play.
One thing to be aware of is that our application suite is in C++, so
we have mangled symbols in the definitions.

See
TRACEPOINT_EVENT(
sapphire,
ip_error,
TP_ARGS(
int, lineno_arg,
int, socket_arg,
int, errno_arg
),
TP_FIELDS(
ctf_integer( int, source_line, lineno_arg )
ctf_integer( int, socket, socket_arg )
ctf_integer( int, errno, errno_arg )
ctf_string( error_text, strerror( errno_arg ) )
)
)
TRACEPOINT_LOGLEVEL( sapphire, ip_error, TRACE_ERR )
It maps to this in the metadata at line 4295:
event {
name = "sapphire:ip_error3";
id = 349;
stream_id = 0;
loglevel = 13;
fields := struct {
integer { size = 32; align = 8; signed = 1; encoding = none; base = 10; } _source_line;
string _address;
integer { size = 32; align = 8; signed = 1; encoding = none; base = 10; } _port;
integer { size = 32; align = 8; signed = 1; encoding = none; base = 10; } _(*__errno_location ());
string _error_text;
};
};
I suspect that "error_text" is actually a C++ macro that maps to "(*__errno_location ())",
which is unexpected.
Thanks,
Mathieu

Sorry, I meant that "error" maps to "(*__errno_location ())", in the
line "ctf_integer( int, errno, errno_arg )".

Doh, have I got egg on my face :)
errno is about as global a symbol as they come - oh well, easy fix.
Many thanks all for the prompt help.

Having spent about a week moving some 1500 trace statements over to
lttng, I figured it was time to try a test run. Unfortunately there
seems to be a problem with the metadata.
Any clues as to what to try next?
