Prerequisites for Pairwise Configurations

Tip When configuring the Matching Criteria, you do not need to specify any of the ciaNames that NNMi automatically takes into account. See Matching Criteria Configuration Form (Identify Incident Pairs) for more information.

When matching incidents, NNMi automatically takes into account the following values:

  • SNMP Trap incidents. NNMi takes into account from which device the trap originated using the cia.address value of the source address of the trap.

  • Management Event incidents. NNMi takes into account the name of the incident's Source Object and Source Node.

    Tip NNMi displays the Name value used to identify the Source Node and Source Object in the Source Node and Source Object attribute for each incident in the Incident form.

  • Syslog Message incidents. NNMi does not automatically use any matching criteria.

If you must provide more details to accurately identify the logical pair of incidents (from among all possible incidents related to that source node), complete the Optional step 6 below.

Complete the following steps before attempting to set up a Pairwise Configuration:

  1. Identify the incidents or SNMP traps that consist of the logical relationship that makes the pair.

    Note The incident configurations you select can be the same or different for each pair.

  2. Configure those two incidents or traps within NNMi, if they are not already configured:

  3. Generate one of each of the incidents or SNMP traps so you can see an example of each in one of the NNMi Incident views. See Views Available in NNMi.
  4. To display the Incident form, double-click the row representing the first sample incident for the pair.

    Navigate to the Custom Attributes tab. These are the custom incident attributes available to use in step 6, below. See Custom Incident Attributes Provided by NNMi (Information for Administrators) for more information about Custom Attributes.

  5. Repeat the previous step with the second sample incident for the pair.
  6. Optional. If both Pairwise incidents have custom attributes, you can refine the match criteria beyond what NNMi automatically uses to determine a match. Some incident pairs require extensive details to verify an accurate match. See Pairwise Configuration Form (Correlate Pairs of Incidents).
