Help creating a timestamp script to record mem usage
Hi,
I'm looking into doing a few performance tweaks by adjusting my max memory on a few lpars.
I would to create a time stamp script so i could review it for a week and determine how much space i can lower my max memory to so i could reclaim and allocate that memory to where it is needed the most.
I know the command I need is
I am not sure how to create a timestamp in ksh. I've tried a few things but not working.
Basically I want to capture my real memory usage every hour... I will create my cronjob to run it every hour on the hour, I also need it output to a file.
Just to make sure too, if you're going to run it hourly you want to change the date to append instead of replace. Your output file will be a little short otherwise.
