none of that stuff should be in a kernel module. a simple daemon is far
more appropriate.
you can get the CPU info out of /proc/cpuinfo
you can get the ram info out of /proc/meminfo
you can get the HDD info from /bin/df
you can get the process info from /bin/ps
the logs are all in regular files as /var/log/***
the user login info can be found by parsing /var/log/wtmp
the network connections via /bin/netstat -an
the hardware info from lspci or lshw
thats a lot of redundant and voluminuous information to be fetching
every 5 minutes,
