Interface Statistics workspace
The Interfaces Statistics workspace displays information about the data that flows through Loopback, OSA-Express Queued Direct I/O (QDIO) Ethernet, HiperSockets, and Multipath Channel Point-To-Point (MPCPTP) interfaces and the IP addresses associated with all interfaces on a z/OS® v1.12 or later system.
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.
Note: This workspace returns data only on systems running on z/OS v1.12 or later.
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.
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)
