Web Hosting Talk : Web Hosting Main Forums : Hosting Security and Technology : How to limit resources ? (cpu, memory usage)

[GreenSea]

Hi

How can I limit my dedicated server's resources ? For example, one of reseller provider's limits :

Resellers may not use more than 2% CPU daily, 3% memory daily, run more than 10 simultaneous processes per user, allow any process to run for longer than 30 seconds CPU time, run any process that consumes more than 20% of available CPU at any time, or run any process that consumes more than 16 MB of memory. Databases are limited to 16 max user connections with a max query time of 8 seconds. Cron jobs must not execute more than once every 15 minutes and will be niced to 15 or greater.

From where or how can I configure these limits ?

Thanks for helpful replies..

You can't on a shared server, all you can do is suspend clients that don't follow your ToS and overuse resources.

GreenSea,

You can configure this. But, will need to write script for this and should run this as a deamon, so that, it checks all user processes and apply the limit. With mere tweaking of the server and configuration changes, this kind of limitations cannot be achieved.
