[lttng-dev] Regarding lttng enable-event using filter option

[Venkata Kantimahanthi]

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
