Perf probes: How can we add the dynamic trace points created by perf probe into lttng? When I add the perf probe as kprobe type I get missing tracepoint error, If I add the perf probe as tracepoint , Lttng does not complain but it does not collect any data when the tracepoint is hit.
perf probe -l probe:tcp_gro (on tcp_gro_receive@net/ipv4/tcp_offload.c with addr len) lttng enable-event -k --probe=tcp_gro Error: Missing event name(s). When I add it as a trace point lttng enable-event -k probe:tcp_gro Kernel event probe:tcp_gro created in channel channel0] it does not give any error but no data is collected Module tracepoints: I created module tracepoints in the kernel and compiled the trace points. The header file is in the driver module directory. When I write the adaptation layer for lttng, it does not compile as it is not able to fien the header file. I have given fill path name to the header file and still it does not work. Thanks
