Interface Statistics workspace
The Interfaces Statistics workspace displays information about
the data that flows through the following types of interface and
the IP addresses associated with all interfaces on a z/OS v1.12 or
later system:
- Loopback
- OSA-Express Queued Direct I/O (QDIO) Ethernet
- HiperSockets
- Multipath Channel Point-To-Point (MPCPTP)
The statistics that are returned by the request are similar to
those in the output of the Netstat DEVLINKS/-d report.
Statistics are provided for all strategic interface types except
for VIPA interfaces; the stack does not maintain counters for VIPA
interfaces.
Notes:
- This workspace returns data only on systems running on z/OS v1.12
or later
- If all of the TCP/IP stacks you are monitoring are running on
z/OS v1.12, consider making this workspace your default workspace
from the Interfaces Navigator item. Refer to the section "Upgrade
issues related to z/OS v1.12" in the upgrade chapter of the IBM Tivoli OMEGAMON XE for Mainframe Networks: Planning and Configuration Guide for information about how to make
the Interface Status workspace and its associated workspaces the default
from the Navigation tree.
This workspace can be accessed by right-clicking on the
Interfaces Navigator item in the Navigation tree and selecting Interface Statistics from the list of available
workspaces. You can also reach this workspace from summary table links
in the following workspaces:
This workspace can also be displayed by clicking on the Link icon
in the Interface Status Summary table and selecting Interface Statistics from the list of available
workspaces. The link to this workspace is a conditional link and is
displayed in the list of available links only if the value of the Interface Type attribute in the Interface Status
workspace is one of the following types:
- Loopback (1)
- OSA_QDIO_ethernet_OSD (2)
- OSA_QDIO_ethernet_OSM (3)
- OSA_QDIO_ethernet_OSX (4)
- Hipersocket (5)
- MPC_ptp (6)
- MPC_ptp_samehost (7)
- MPC_ptp_xcf (8)
The Interface Statistics workspace provides the following views:
- Bytes Received and Transmitted: Displays
the number of Received Bytes and Transmitted Bytes by the interface
name for the current collection. The y-axis is the count of bytes.
The x-axis consists of two bars for each defined strategic interface,
denoting number of Received Bytes and number of Transmitted Bytes
for this interface for the current collection interval. This information
is presented in a bar chart where:
- Yellow represents the number of Received
Bytes.
- Blue represents the number of Transmitted
Bytes.
- Bandwidth Utilization: Displays the percent
total bandwidth utilization by interface name for the current collection
interval. The y-axis is the percentage. The x-axis consists of one
bar for each defined strategic interfaces, denoting the percent total
bandwidth utilization for this interface for the current collection
interval. This graph is filtered to include only interfaces with
bandwidth utilization values greater than zero. This information is
presented in a bar chart where:
- Yellow represents Bandwidth Utilization.
- interface_name Interface Address Summary
table: Displays addressing information
about a single interface.
- Packets Discarded: Displays the percentage
of packets discarded by interface name for the current collection
interval. The y-axis is the percentage. The x-axis consists of one
bar for each defined strategic interface, denoting the percent packets
discarded for this interface for the current collection interval.
This graph is filtered to include only interfaces with packets discarded
values greater than zero. This information is presented in a bar chart
where:
- Yellow represents Percent Packets Discarded.
- Packets in Error: Displays the percentage
of packets in error by interface name for the current collection interval.
The y-axis is the percentage. The x-axis consists of one
bar for each defined strategic interface, denoting the percent packets
in error for this interface for the current collection interval.
This graph is filtered to include only interfaces with packets in
error values greater than zero. This information is presented in a
bar chart where:
- Yellow represents Percent Packets in Error.
- Interface Statistics Summary table:
Displays information about the data that flows through the following
interfaces on a z/OS v1.12 or later system:
- Loopback
- OSA-Express Queued Direct I/O (QDIO) Ethernet
- HiperSockets
- Multipath Channel Point-To-Point (MPCPTP)
interface_name Interface Address Summary
table
The interface_name Interface Address Summary
table displays addressing information about a single interface.
For a complete list of the attributes available in the Interface
Address Summary table, and a brief description of each, see the KN3 Interface Address Attributes help panel.

Right-click on the link icon in a row of the Interface Statistics
Summary table to access one of the following workspaces:
- Interface Status workspace: The
data displayed in this workspace is filtered based on the Interface Index attribute in the Interface Statistics
workspace.
- Data Link Control (DLC) Read and Write Queue Statistics workspace: The data displayed
in this workspace is filtered based on the Interface
Type attribute in the Interface Statistics workspace. The link
to this workspace is a conditional link and is displayed in the list
of available links only if the value of the Interface
Type attribute in the Interface Status workspace is one of the
following types:
- OSA_QDIO_ethernet_OSD (2)
- OSA_QDIO_ethernet_OSM (3)
- OSA_QDIO_ethernet_OSX (4)
- Hipersocket (5)
- Interface Statistics History workspace
- Interface Address: Displays addressing information
about a single interface.
