How to get uftrace data before the process terminates?

[qiuxinyun2010]

I run an agent for a daemon process. I want to use the uftrace.data for report or generate graph before killing the daemon process。

Try uftrace -p $PID --trigger .@finish.

Try uftrace -p $PID --trigger .@finish.

termnial1：
uftrace record -P main -l -g app
If pid is 26709
termnial2：
uftrace -p 26709 --trigger .@finish
uftrace replay
show
WARN: cannot open record data: uftrace.data: No such file or directory

When I
kill 26709
uftrace replay works and show result.

Ok, I think you need to terminate uftrace record process after hitting the finish trigger.

Try this again in terminal2:

$ uftrace -p $PID -T .@finish
$ kill -S INT `pidof uftrace`
$ uftrace replay
