CPU Utilization based on user

[Hasim.Baba]

Hi,

This should be a easy 10 pointer... what is teh command to get total cpu utilization for user root or any other user. I am planning to use this command in a script.

Two steps:

1. top -s 10 -d 1 -n 1000 -f /tmp/top.txt

2. awk '{if($4=="USERNAME"){p=1;getline;}if(p==1)cpu[$4]+=$11}END{for(u in cpu)print u,cpu[u]}' /tmp/top.txt

These commands add up all the cpu and outputs the total for each user.
Remember to remove /tmp/top.txt between each run, otherwise top appends to the file.

You da Man !!!

I hope this runs on HPUX 11.x ?

Also, can u please tell me if I have to sum the utilization for all the users it can be done wiht the same command ?
I am basically trying to make a script in which I total the utilzation for three users and than compare if it does not take more than 30 percent of total utilzation for all the users.

Thanks again

Yes it is OK for 11.x

Try this for user's cpu, total and proportion of users into total:

awk '{if($4=="USERNAME"){p=1;getline;}if(p==1){cpu[$4]+=$11;tot+=$11}}END{for(u in cpu)print u,cpu[u],tot,(cpu[u]/tot)}' /tmp/top.txt

Pipe the output into

sort -rnk2 to get the worst users at the top of the list.
