I have a running demo on a Linux server which consumes quite a bit

  • 0

I have a running demo on a Linux server which consumes quite a bit of CPU and Memory usage. These parameters keep changing based on the load of the running demo. I want to extract the CPU usage and Memory usage periodically , i.e. every 3-4 sec and create a plot of the extracted result.

Considering the process as ” Running Demo”, on the terminal I typed:

ps aux |grep Running Demo | awk '{print $3 $4}'

This gives me the CPU and Memory usage of Running Demo. But I want the next two things i.e.
1) get this result outputted every 3-4 sec.
2) Make a plot of the generated result.

Any help or suggestion will be highly appreciated. I am a starter in this community.

Thanks

    What you are trying to do is well known as an existing project :

    See Munin

    EXAMPLE

    enter image description here

    NOTE

    • it’s supported by the Open Source community, so…
    • it will be stronger
    • don’t run odd commands like ps aux |grep Running Demo | awk '{print $3 $4}' but ps auxw | awk '/Running Demo/{print $3 $4}'
    • many plugins exists and works for basics : CPU, RAM, FW, Apache and many more
    • if you really need gnuplot, see a top 3 on a goggle search http://blah.token.ro/post/249956031/using-gnuplot-to-graph-process-cpu-usage
