Hi Masatake, I was not able to get the client traces but I can find a workaround to generate those spans myself and get a graph. I had one more question related to htrace.
If both client process and server use the same file to log htraces, then is there a possibility of corruption while writing to the span log file? Since there will be 2 JVMs writing to the same file. In addition, our client is multithreaded too. I can use synchronize on the client side and make sure multiple threads write the client spans in exclusion, however there can be a problem if a server span is being written at the same time. Let me know what you recommend. Thank you.
