Hello, Thanks a lot, It worked, i am able stream and save the trace on the remote PC.
However out of curiosity i am also trying to do live tracing, On Mips Board lttng-relayd -vvv lttng create --live 10000000 -U net://localhost remotetes lttng enable-event -a -k lttng start On linux PC lttngtop -r net://192.168.233.39 net://192.168.233.39/1 : remotetes on host Linux_Mips(timer = 10000000, 4 stream(s), 0 client(s) connected) Segmentation fault (core dumped) What is the exact steps i need to follow for live tracing, Thank you Skumar On Tue, Feb 11, 2014 at 8:27 PM, David Goulet <[email protected]> wrote: > On 11 Feb (13:24:15), kumar s wrote: > > Hi, > > > > I am trying to start the trace on MIPS board and dump it remotely on PC. > > > > The steps i do > > On MIPS board: > > lttng create -U net://192.168.233.207 newsession > > > > lttng enable-event lttng_statedump_start -k > > > > Error: Event lttng_statedump_start: Unable to connect to lttng-relayd > > (channel channel0, session news) > > Warning: Some command(s) went wrong > > > > In lttng-sessiond -vvv log > > > > [...] > > DEBUG3 [1918/2019]: Consumer socket created (fd: 30) and added to output > > (in consumer_create_socket() at consumer.c:300) > > DEBUG1 [1918/2019]: Setting relayd for session news (in > cmd_setup_relayd() > > at cmd.c:722) > > DEBUG3 [1918/2019]: Relayd connect ...
