Management Information Base (MIB)
About MIB
The Management Information Base (MIB) is a collection of managed objects structured as a tree. The MIB is not a database but rather defines the structure of the name space. The MIB is similar to the table of contents of the SNMP agent. The structure of the MIB tree is hierarchically structured starting from the root. Each leaf of the tree is identified by a unique object identifier (OID). Additionally, the data type and identifier is defined for each leaf. If an extension dll is integrated, then for the OID area that offers the extension dll an MIB extension must be developed that makes it possible to translate the OID into a value. In this sense the MIB is a library that assigns an OID an identifier and the data type. The newly developed MIB area must fit to the name space of the extension dll and can be fed into the SNMP manager, making it possible for the manager to translate the OID. From the MIB the manager knows then how it must interpret information from the agent.
The MIB area of a certain extension agent is determined by the manufacturer and must be adapted to the OIDs that are available as part of the extension dll. The notation of the MIB corresponds to Abstract Syntax Notation One (ASN.1). To avoid ambiguity, the manufacturer should reserve a so-called private enterprise number at www.iana.org, from which the manufacturer-specific subtree of the MIB spans. The manufacturer-specific part of the MIB begins at OID 1.3.6.1.4.1. [=iso(1).org(3).dod(6).internet(1).private(4).enterprises(1)]
As the next number in the OID sequence the private enterprise number must then be appended, which serves as the root for the manufacturer-specific sub tree.
(Example 1.3.6.1.4.1.28106). The ID 28106 is registered with IANA to Geutebrueck.

Once the SNMP AGENT has been correctly installed, GCoreDiagnosticsSnmp.dll is integrated on the target system, and the properties of the SNMP service regarding trap targets and SNMP access rights have been adapted, an SNMP manager can access the GBSNMP values via the network. When the Windows Agent receives a query that relates to the Geutebrück sub tree, this is automatically forwarded to GCoreDiagnosticsSnmp.dll. (During initialization of the DLL the Geutebrück private enterprise number is given to the Masteragent, ensuring that Geutebrück queries are forwarded to GCoreDiagnosticsSnmp.dll).
To ensure correct display in the SNMP MANAGER, the GBMIN.mib must be made available to the manager.
In the following the individual OIDs of the GBMIB.mib only for G-Core/Diagnostics are described. An extra copy of the MIB itself is stored during installation of G-Core/Diagnostics in the G-Core directory.
