We own a few servers, each with about 100 users on it, some with 1 domain, some with a few. I'm looking for a script which runs in the background which can provide information about which users uses which amount of resource.
I'd like to know what the load on our server is,
top only gives me a 'now'-view, I want to be able to check out the load for a period of time.
To make it more detailed, I'd like this per user, and if possible even more specific (which files are used a lot, or database usage, anything I can use to optimise a bit)
I have no clue whether this exists, I can only find some code which only gives my live results, like
ps, that's not what I'm looking for.
