Using Substitution Variables with SNMP OID information

A matching SNMP MIB (Management Information Base) file can be used to map SNMP OIDs to object names. However, without the MIB data, the incoming trap would have been displayed as a series of unique numbers such as: OID 1.3.6.1.4.1.14867.1.1.2.2.8.

If there is no MIB available for the SNMP trap being received, it is possible to use substitution variables to override the alert text by specifying the unique OID number as the variable name as shown in the screen shot below.

NOTE: When using any variable that contains a space, such as OID information, ensure that the variable text is enclosed in quotation marks.

To decide on the information that should be captured in order to get the most meaningful results in the alert text, setup a test rule first and see what is generated. From this information, it is possible to then determine the details to be captured and set the substitution variables accordingly.

NOTE: For more information on using Substitution Variables within Enterprise Console, see Working with Substitution Variables.
