Hello,

I have just started using lttng and still looking at documentation.
Can you help me with some info.

How does the app register to use lttng?
how do sessiond, app and lttng-ust interact? is there any socket from every
app to sessiond?
How is the app modified when instrumented using lttng? are there any
threads added?
when lttng instrumentation is linked along with app
Are there any powerful tools for analysis on collected traces.

/Jam

Hi lttng-dev,

sorry for asking basic questions.
Can you guys point me to any documentation which has this info. lttng.org
documentation doesnt have info about this.

How does the app register to use lttng?
how do sessiond, app and lttng-ust interact? is there any socket from every
app to sessiond?
How is the app modified when instrumented using lttng? are there any
threads added?
Are there any powerful tools for analysis on collected traces.
