MIB data collectors
The Management application enables you to define a data collector by mapping a MIB object to a
unit name in the mib_unit.properties file. This property file is located in the
Install_Home/conf/mibs directory. The default mib_unit.properties file contains commonly used
MIB unit definitions.
Once mapped, the unit name displays on the line chart of the performance graphs when you select
that MIB object as a data collector.
You can map a unit name from either a MIB name or MIB object identifier (OID).
Example
#MIB OID mapping
1.3.6.1.2.1.31.1.1.1.6 = Octects
#MIB name mapping
ifHCInOctets=Octects
Mapping a MIB object to a unit name
To map a MIB name or OID to a unit name, complete the following steps.
1. Open the mib_unit.properties file in a text editor.
The mib_unit.properties file is located in the Install_Home/conf/mibs directory.
2. To map a MIB OID, use the following format:
1.3.6.1.2.1.31.1.1.1.6 = Octects
3. To map a MIB name, use the following format:
ifHCInOctets=Octects
4. Save and close the file.
You can then annotate the performance graphs using the unit name by assigning the MIB
object as a data collector. For counter values, the unit name is appended with “/sec” to
indicate the rate information for that counter value.
If you def ine a da ta colle ctor wi th a MIB o bject that does not have an associated unit name, the
unit name displays as an empty string on the performance graph.
