Interfaces workspace

The Interfaces workspace provides information about TCP/IP interfaces.

This workspace is displayed by clicking the Interfaces Navigator item in the navigation tree. Right-clicking on the Interfaces Navigator item and selecting Workspaces provides access to these additional workspaces:

Notes:
  1. If the address space being monitored is running on z/OS v1.11 or earlier, the values for these attributes are retrieved using SNMP. If the address space being monitored is running on z/OS v1.12 or later, the values for these attributes are retrieved using the z/OS Communications Server callable network management interface (NMI).
  2. The Interface Status and Interface Statistics workspaces contain data only if the address space being monitored is running on z/OS v1.12 or later. These workspace were created to exploit the z/OS v1.12 or later callable network management interfaces (NMI) feature.
  3. The workspace is deprecated. When z/OS v1.12 is the lowest level of z/OS supported by the OMEGAMON monitoring agents, this workspace will no longer be the default workspace and may be removed.
  4. If you are viewing this workspace on z/OS v1.12, non-strategic interfaces report only status information. Performance-related attributes show a value of zero (0). The strategic interfaces have one of the following Interface Types:
  5. Under z/OS v1.11 or earlier, it is possible for the value of the Percent Inbound Packets in Error attribute to actually exceed 100%. This occurrence is due to the way inbound packets and errors are counted in the Communications Server TCP/IP stack. Many errors are encountered and recorded before the stack can determine how many packets were received, or whether the packets are unicast, multicast, or broadcast. In this case, the TCP/IP stack records the error, but not the inbound packet. In unusual circumstances, the number of errors recorded might exceed the number of inbound packets recorded.
  6. DVIPA reporting has changed between z/OS v1.11 and z/OS v1.12.

    In z/OS v1.11 and earlier, when SNMP is used to report DVIPA data, this workspace will display DVIPAs. The following attributes are reported for a DVIPA in the Interfaces workspace pre z/OS v1.12:

    This limited DVIPA support is because z/OS Communications Server does not provide performance metrics (such as packet and byte counts) for DVIPAs. Performance metrics have always displayed as zero (0) regardless of z/OS release or collection method.

    In z/OS v1.12 and later, DVIPAs are no longer reported in the Interfaces workspace. DVIPAs are now reported in the Gateways and Devices workspace.

The Interfaces workspace provides the following views:

Interfaces Summary table

The Interfaces Summary table contains one row for each TCP/IP interface and provides a summary of detailed information for each. The Interface attributes can display performance and identifying information for a specific interface.

To view historical data about any interface in the Interface Summary table, right-click the Link icon by a row in the table to display the Interfaces History workspace for that interface for a specified time period. The default is the last 24 hours.

For a complete list of the attributes available in the Interfaces Summary table, and a brief description of each, see the Interfaces Attributes help panel.
