SNMP MIB's or single OID's found by reverse engineering.

Under this section you can find two different categories:

1. Full *.MIB files
These files are found from public internet and are free to download.

2. Single/Multiple SNMP OID's which are found by reverse engineering.
Some vendors does not publish their mibs and you are forced to use their software (some ugly java client etc.). OID's available under this section are found by reverse engineering. Full scan of snmp-tree (snmpwalk) and later the analyze (comparing the snmp values against java client visual indication or web interface, or even some additional measurement by some tool).
