+# Usage: collect-system-stats.sh <delay-in-seconds>
+# This script starts sar/top/iostat/vmstat processes which collect system stats
+# with the interval <delay-in-seconds> given as argument to the script. When
+# the script is stopped either by entering any input or Ctrl+C the list of
+# files where output is captured will be printed on the screen which can be
+# observed to find any problems/bottlenecks.
