Interface Statistics History workspace
The Interfaces Statistics History Workspace provides historical
information about a selected TCP/IP interface. This workspace displays
the most recent 24 hours of historical data by default. This workspace
displays historical information about the data that flows through
the following types of interface 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.
Note: This workspace returns data only on
systems running on z/OS v1.12 or later.
This workspace can be displayed by clicking on the Link icon in
the Interface Statistics Summary table and selecting Interface Statistics History 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 Index attribute in the Interface Status
or Interface Statistics 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)
Note: Historical data collection of the KN3
Interface Statistics and KN3 Interface Address attribute groups is
required if you want to display data in this workspace.
The Interface Statistics History workspace provides the following
views:
- Bytes Received and Transmitted: Displays
the number of Received Bytes and Transmitted Bytes by the interface
name for the most recent historical collection interval. 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 most recent
historical 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 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 most recent historical
collection intervals. 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 historical 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 Address Summary table
The Interface Address Summary table displays historical addressing
information.
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.
