Interfaces

CA APM Cross-Enterprise monitors data for the following Interfaces metrics from a connected CA NetMaster NM for TCP/IP region:

Bandwidth

Displays the total available bandwidth.

Note: This metric is available only for physical interfaces such as OSAs, where the total available bandwidth is known.

Input Bandwidth (0.01%)

Displays the percentage of available bandwidth for this stack network interface that inbound data uses.

Output Bandwidth (0.01%)

Displays the percentage of available bandwidth for this stack network interface that outbound data uses.

Packets Discarded (0.01%)

Displays the percentage of packets (both sent and received) that were discarded, despite containing no errors.

This interface was unable to process these packets, possibly because of interface buffer space or other resource constraints. Interface capacity shortages or configuration problems can prevent processing.

Packets in Error (0.01%)

Displays the percentage of packets (both sent and received) that contained errors.

Interface hardware or line problems can cause interface packet errors.

All interface metrics are sent every 5 minutes. Values for the loopback and virtual (zero traffic) interfaces are not included.

All these Interface metrics come from the latest sample values of stack network interface data sampling. The calculation interval therefore depends on the monitoring interval that is chosen for stack network interface Performance Monitoring.

For detailed diagnosis of stack network interface activities, use these functions in the CA NetMaster NM for TCP/IP region:

• Use Stack Interface and Device Links, accessible by the /DEVLINK panel shortcut.
• Use the stack network interface performance data displays (WI command next to a stack on the IP Resource Monitor).
