Identification and Match Criteria Configuration

Depending on your data source, available credentials, and specific system security settings, an integration point may have access to only a limited set of attributes when identifying a CI.

For example, IP range discovery detects two IP addresses (10.12.123.101 and 16.45.77.145), and creates two nodes. However, detailed system discovery may detect that those two IP addresses are actually configured on two network interfaces in the same node.

This means that you cannot always rely on a single matching set of attributes for identification – other possible attributes that can potentially help to identify the CI should also be listed. In the previous example, the node identification attributes can be the IP address and the network interface. If you use the IP address to identify the CI, you see that all three discovered nodes are the same node.

Suppose that detailed system discovery detects a node with IP address 10.12.123.101 and network interface MAC1. At some point, that node was shut down, and the same IP address (10.12.123.101) was given to another node with network interface MAC2. These two nodes have the same IP address; however; it is obviously not the same CI. Performing match validation on the network interface data helps us to realize that it is not the same node.

The identification criteria are used to select candidates, and the match criteria are used to approve the identification result or dismiss it. For example, while handling input CI A, we may get identification candidates B and C, and the match criteria will dismiss B. In that case, we are left with C, which means that A is identified as C.
