I really like that people are valuing monitoring and making tools to do it, but I mean how is this better then SNMP? It doesn't look like it gives any more information then the prTable of the UCd-SNMP-MIB (http://www.net-snmp.org/docs/mibs/ucdavis.html http://www.net-snmp.org/docs/mibs/ucdavis.html) Also if you used snmp instead of rolling your own agent you would get security and encryption (SNMPv3) and the ability to use one of any number of existing monitoring tools.
