What do you plan to do with the data? On the local host most is already
available through the /proc interface (things that look like files to user
programs) and tools already exist to read and display the values. If you want
to collect data from remote hosts, snmp is the appropriate protocol and again,
tools already exist.

Normally kernel modules would only be used to communicate with specific hardware
(and errors introduce the risk of crashing). Everything you mention is already
available without kernel changes, although some might be reported in less than
optimal ways.
