Looking good.  At time 1023149803 you insert 3488, 64656 and 58572

The size of the RRA is *very* short.  Although correct, I think you
want it larger.  You are telling rrdtool to keep stats for 300*24 seconds.
Also you indicate you want per minute stats --> use "--step 60".

Almost correct.

You can:
   rrdtool update monitor-mem.rrd 1023149803:3488:64656:58572
   rrdupdate monitor-mem.rrd 1023149803:3488:64656:58572
or you change the output of your script into
   update monitor-mem.rrd 1023149803:3488:64656:58572
and then call rrdtool so:
   rrdtool - < myscript.sh
