perf on running process in Linux

For profiling, we can use perf in Linux. But all examples showing only executables.

In CentOS, is it possible to run perf tool on running process or daemon?

perf record and perf stat support the -p option which you can use to specify the PID of the process to attach to. For example , the command:

perf stat -p 3129

tells perf stat to attach to the currently running process with PID 3129.
