Hello everyone, I was working on a use case where I am working on enabling LTTng on an embedded ARM device running the OpenBMC linux distribution. I have enabled the lttng yocto recipe and I am able to trace my code. The one thing I am concerned about is the performance overhead. Although the documentation mentions that LTTng has the lowest overhead amongst all the available solutions, I am concerned about the overhead of the LTTng UST in comparison to other available tracers/profilers. I have used the benchmarking setup from lttng-ust/tests/benchmark at master ยท lttng/lttng-ust (github.com) <https://github.com/lttng/lttng-ust/tree/master/tests/benchmark> to benchmark the overhead of the tracepoints (on the device). The benchmark, please correct me if I am wrong, gives the overhead of a single tracepoint in your code. Although this might be fine for now, I was just wondering if there are any published benchmarks comparing LTTng with the available tracing/profiling solutions. If not, how can I go about benchmarking the overhead of the applications?
I have come across the lttng/lttng-ust-benchmarks (github.com) <https://github.com/lttng/lttng-ust-benchmarks> repository which has no documentation on how to run it, apart from one commit message on how to run the benchmark script. Any help is really appreciated. Thank you. Regards, Aditya
