Hi ,
I haven't correctly formatted my previous mail. Actually I tried like that
yet I see that trace logged . You have any idea ?
See, my requirement is that I have to filter the traces through message
(data) written in the trace.
More over is there any filtering that can be done using bit values in a
integer data supported in lttng ?
Thanks & Regards

Subject: Re: [lttng-dev] Regarding lttng enable-event using filter
option
Hey,
I believe you have it wrong, with that filter, only the messages
with strfield == "TRACE_UTS" will be logged.
Try strfield != "TRACE_UTS"
I use a filter to filter traces based on process using the pid, and so to
filter trace processes by their pid, I use the following:
$ctx.vpid == XYZ, where XYZ is the pid of the process I want to trace.
I hope this helps,
Glen Keane.

Hi ,
I am trying to filter the following trace using lttng command but it was
not filter out . Can any one help me?
[1970-01-01 00:04:58.386338797] (+0.000003280) oamhost
com_ericsson_trithread:TRACE_UTS: { cpu_id = 19 }, { sec = 333, usec =
2222, process = "test111", fileAndLine = "demo_legacy.c:123", msg = "This
is a TRACE_UTS from test3", _dataUts_length = 0, dataUts = [ ] }
lttng enable-event -s sessionname -c ch1 -u -filter 'strfield =!
"TRACE_UTS"' com_ericsson_tri*
o/p
Event com_ericsson_tri*: Filter 'strfield == "TRACE_UTS"' successfully set
So , If I have enabled above event with filter , the traces which have
string field with TRACE_UTS as data should not be logged. This is as per
my understanding. Is is correct ?
Because the traces were not filtered.
Thanks & Regards
