OSA Channels workspace
The OSA Channels workspace provides OSA-Express channels usage
information, showing utilization percentages by channel identifier.
OSA cards provide channel connectivity between IBM(R) mainframes and attached networks. Configuration
and performance data for OSA cards is then collected by an IBM SNMP
OSA subagent and stored in the IBM MIB where it is available to network
management applications. If multiple OSA cards are used, there are
multiple sets of the two OSA channel utilization values on the bar
charts in the OSA Channels workspace.
To display the OSA Channels workspace, click the OSA navigator
item for a specific TCP/IP stack.
Note:
The OSA-Express3
adapter on z/OS(R) v1.10 or above can
have only 1 port per OSA CHPID or two per physical card or feature.
The OSA Channels workspace contains the following views:
- 1 Minute Resource Utilization: Displays
the average, over a 1-minute interval, of the percentage of
time that resources were utilized to transfer data. The information
is presented in a bar graph where:
- Yellow represents PCI utilization, the average
percentage of time that the PCI bus was utilized to transfer data
over the current collection interval.
- Blue represents processor utilization, The
average percentage of time that the CHPID processor was utilized to
transfer data over the current collection interval.
- 5 Minute Resource Utilization: Displays
the average, over a 5-minute interval, of the percentage of
time that resources were utilized to transfer data. The information
is presented in a bar graph where:
- Yellow represents PCI utilization, the average
percentage of time that the PCI bus was utilized to transfer data
over the current collection interval.
- Blue represents processor utilization, The
average percentage of time that the CHPID processor was utilized to
transfer data over the current collection interval.
- 1 Hour Resource Utilization: Displays the
average, over a 1-hour interval, of the percentage of time
that resources were utilized to transfer data. The information is
presented in a bar graph where:
- Yellow represents PCI utilization, the average
percentage of time that the PCI bus was utilized to transfer data
over the current collection interval.
- Blue represents processor utilization, The
average percentage of time that the CHPID processor was utilized to
transfer data over the current collection interval.
- OSA-Express Channels Summary table: Provides
extensive channel configuration data, such as device name, channel
type, whether the device is online or off line, and processor utilization.
Each row in this table links to the OSA Ports workspace
and the OSA-Express LPARs workspace.
Right-click a row in this table to access those links. The default
is the OSA-Express LPARs workspace. By
right-clicking on the Link icon by a table row,
you can link to the OSA Ports workspace
and the OSA-Express LPARs workspace.
OSA-Express Channels Summary table
The OSA-Express Channels Summary table contains extensive channel
configuration data, such as Device Name, Channel Type, whether the
interface is online or off line, and processor utilization. Each row
in this table links conditionally to the OSA
Ports workspace and the OSA-Express LPARs workspace.
Right-click a row in this table to access those links. The default
is the OSA-Express LPARs workspace.
For a complete list of the attributes available in the OSA-Express
Channels Summary table, and a brief description of each, see the OSA-Express Channels Attributes help panel.
