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?
Check this out.
It compiles the sort of thing you're doing into a loadable dynamic kernel module, that loads without having to do a reboot.
