You are really awesome. Saved my day. Implemented this perfectly.

---------- Post updated at 03:47 PM ---------- Previous update was at 02:59 PM ----------

I have an other problem. I'm trying to record metrics of an application called memcached which is server client based application. So I started the server using 'memcached -t 4 -m 4096 -n 550' and in other window started the client. So the connection is established. Now I'm trying to get the pid of server and passing that as an input argument to perf using this command:

perf stat --log-fd 3 -e cycles -p $pid 3>result.log &

But according to your program the data is not being forwarded to the result file. At the end of the execution the result file is empty. Can you please help me with this?

PERF-MEM(1)							    perf Manual 						       PERF-MEM(1)

NAME

       perf-mem - Profile memory accesses

SYNOPSIS

       perf mem [<options>] (record [<command>] | report)

DESCRIPTION

       "perf mem -t <TYPE> record" runs a command and gathers memory operation data from it, into perf.data. Perf record options are accepted and
       are passed through.

       "perf mem -t <TYPE> report" displays the result. It invokes perf report with the right set of options to display a memory access profile.

OPTIONS

       <command>...
	   Any command you can specify in a shell.

       -t, --type=
	   Select the memory operation type: load or store (default: load)

       -D, --dump-raw-samples=
	   Dump the raw decoded samples on the screen in a format that is easy to parse with one sample per line.

       -x, --field-separator
	   Specify the field separator used when dump raw samples (-D option). By default, The separator is the space character.

       -C, --cpu-list
	   Restrict dump of raw samples to those provided via this option. Note that the same option can be passed in record mode. It will be
	   interpreted the same way as perf record.
