[CentOS-devel] Collecting data

[derleader __]

 Hi,




 I'm developing C plugin for Centos which will be installed as kernel module. The problem is how to collect the data about:
    CPU
	Check – Utilization, Model, Number of Cores  
	    RAM
	Check – Total Memory, Free Memory,  Memory Load  
	    HDD
	Check – Number of physical HDDs, Number of logical partitions,
	Total space, Free space  
	    Running
	processes – Total number of processes  
	    Logs
	– system logs such as error logs  
	    System
	uptime  
	    Users
	logged in and last login – total list of users  
	    Total
	network connections  
	    Check
	hardware parts model and number    

The kernel module will check the status of the OS every 5 minutes. What is the most efficient way to collect these data?

Regards
Peter
