I am getting an error as follows on running my application :

LTTng-UST: Error (-17) while registering tracepoint probe. Duplicate registration of tracepoint probes having the same name is not allowed.

Based on error, looks like multiple components are trying to register with same tracepoint probes. I am trying to find which are those components. Is there any way to see who all are registering tracepoint probes?

Thanks, Kailas

  • What version of LTTng-UST and LTTng-Tools are you using? Are you using dlopen() in this application? Can you provide a reproducer of this issue (Makefile, tracepoint description and code)?This error means that one than one tracepoint probe (with identical names) are loaded in the same process. – fdeslaur Oct 19 '18 at 11:13
  • Yes, I am using dlopen in this application – Kailas Oct 25 '18 at 06:33
