You might want to take a look at Tracecompass [1]. Tracecompass already seems to support some form of analysis for Virtual Machine [2]. Tracecompass also have widget for remote controll of LTTng via ssh [3]. > > My question is the following: Could my application communicate with LTTng > through TCP protocol ??

LTTng does not offer any direct way to perform control operations over TCP.
