-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Fahad,
So, it seems you don't have a consumer installed on your system that the sessiond can access: DEBUG3: Looking for a kernel consumer at these locations: [in spawn_consumerd() at main.c:1678] DEBUG3: 1) [in spawn_consumerd() at main.c:1679] DEBUG3: 2) /usr/lib/lttng/libexec/lttng-consumerd [in spawn_consumerd() at main.c:1680] DEBUG3: 3) /usr/lib/lttng/libexec/lttng-consumerd [in spawn_consumerd() at main.c:1681] PERROR: kernel start consumer exec: No such file or directory [in spawn_consumerd() at main.c:1795] Also I'm starting to believe that you might have a memory limit problem since you are hitting this: PERROR: sendmsg: Bad file descriptor [in lttcomm_send_unix_sock() at sessiond-comm.c:310] PERROR: send consumer channel: Bad file descriptor [in send_kconsumer_session_streams() at main.c:636] PERROR: ioctl start session: No buffer space available [in kernel_start_session() at kernel.c:397] Because of that, the kernel start session command on the tracer fails... Can you validate that you have enough memory during the commands ? Moving the lttng-consumerd at the right location will at least help a bit :) Thanks!
