Hi, I'm trying to figure out how to use uprobes with lttng.
I can't use a normal uprobe for a line number just using the address I want to probe obtained from objdump? As in: echo 'p /usr/local/bin/my_app:0x2c3a8' >> /sys/kernel/debug/tracing/uprobe_events ... which isn't a function entry, it's just a line of code I want to probe on. This link says it has to be elf or sdt: https://lttng.org/man/1/lttng-enable-event/v2.11/#doc-opt--userspace-probe So can I not probe on just a line of code by specifying an address??? It doesn't look like these methods above will do what I'm wanting to do. I've tried to find examples of using enable-event --kernel --userspace-probe= but there doesn't appear to be many. Thanks, Brian _______________________________________________ lttng-dev mailing list lttng-dev@lists.lttng.org https://lists.lttng.org/cgi-bin/mailman/listinfo/lttng-dev
