Setting Alert Detail Criteria for SNMP Trap Alerts

Alert detail criteria for SNMP trap alerts can be specified in one of two ways, dependent on whether the incoming trap has been assigned with a valid MIB definition, instead of the basic OID value. Operator values are usually set to equals ‘=’.

Therefore, the alert detail text for SNMP Trap alerts can be specified in a similar way as follows:

With a MIB definition:

• Details Text: halEsAlertDeviceName
• Details Value: = MainServer

With an OID definition:

• Details Text: OID 1.3.6.1.4.1.14867.1.1.2.2.3.0
• Details Value: = MainServer

In the above example, an alert is generated for SNMP Trap OID 1.3.6.1.4.1.14867.1.1.2.2.3.0 with a value of MainServer, that also passes other specified criteria.

Each trap entry has an associated type, such as ASN1_OCTSTR or ASN1_INT. Types ASN1_INT, ASN1_COUNTER, ASN_GAUGE and ASN1_TIMETICKS are converted to integer values and all operators can therefore apply.
