Subject: [diamon-discuss] [BUG] perf-convert-to-ctf fails to dealing with syscalls tracepoints.
Date: Mon, 19 Jan 2015 20:12:04 +0800	[thread overview]
Message-ID: <54BCF494.8050808@huawei.com> (raw)

Hi Jiri,

I found a problem when trying to convert syscalls:* records into ctf:

root@arma15el:~# perf record -a -e syscalls:* sleep 5

[ perf record: Woken up 0 times to write data ]
[ perf record: Captured and wrote 4.571 MB perf.data (~199696 samples) ]
Warning:
Processed 64994 events and lost 1 chunks!

Check IO/CPU overload!

root@arma15el:~# perf data convert --to-ctf ./out.ctf
Failed to add field 'nr
Failed to add event 'syscalls:sys_enter_io_submit'.
root@arma15el:~#

Do you have time to have a look at it?

Moreover, is there (diamon-discuss) right place to discuss things related
your perf-convert-to-ctf patches?

Thanks!
