Exam 301 is the sole exam for LPIC-3 designation. It tests skills in authentication, troubleshooting, network integration and capacity planning.
Capacity planning is the art and science of not running out of resources in the foreseeable future. It's often done informally, by measuring the resources that a program needs, commonly after having just run out of something.
If you make a table of how much CPU, memory and I/O bandwidth a program needs to do some unit of work, you can estimate how much it will need at some higher load in the future. Alternatively, you can use the measurements for sizing a new machine for the program, or for estimating how big a machine will be needed to consolidate your other programs.
Informal spreadsheet estimates are often sufficient for simple sizing and future planning, but they do not have any correctness guarantees and they don't tell you:
For that, you use one of the programs which solve the problem using queuing theory. There are commercial products which will do so on Linux, but at least one free queuing network solver exists, Perl::PDQ by Neil Gunther. These generate proper mathematical models, so you can predict the performance of the program under load, and calculate the drop-off in performance as the program becomes overloaded.
