Hello LTTng community, Currently, I'm tracing a java (and Python) application using LTTng. I noticed there is a considerable delay between the time the tracepoint instruction is executed and the time its corresponding event is recorded by LTTng. It seems that the problem comes from the fact that LTTng uses agents to handle java/Python events. Is there any benchmark measuring such delay? Is it possible to minimize this delay (for example by flushing the logger)? Currently, I'm considering putting my tracepoints in a shared library and calling them from within Java code using JNI so that events recording will be "synchronous" with application code execution. Is there any other technique that I can use? Thank you for your help.
