Price of many products were raised and then Flipkart offered discounts but Digital customer is not too dumb to fall in this trap.




Not only Twitter, but  Facebook timelines were full of  Customers Frustration and #Flipkart trolls.

Well , Linux have several ways by which we can easily determine CPU utilization , Utilization per processor , Average utilization and determining which process is  consuming maximum CPU(s)  etc.

While top command is running , Press M  in upper case to sort the memory usage.

The screenshot below shows the Output of Top command:

  1. PID: Process I.D
  2. User : Owner of particular processs
  3. PR : Priority

  9. %CPU : Percentage of CPU used by a particular process
  10. %MEM : Percentage of RAM used by the process

3. mpstat :

Mpstat is used to check per processor stats. For using mpstat , you have to install a package called sysstat

#  mpstat  10 4
