How to measure CPU and memory during load test

Question

We are using JMeter in a heterogeneous environment and we would like to measure CPU and memory while we are producing heavy load on a server where our service or web application is running. What would you recommend to use? Is there any software solution (open source or commercial) available which records CPU and memory usage in a file or to a database?

Thank you!
