In order to facilitate the daily operation and maintenance of a simple piece of writing scripts for obtaining centralized Linux server operating system, CPU, memory usage, load, disk usage, network information.

script is relatively simple, do not explain, friends are interested in your own view.

# obtain basic information about the server scripts
