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 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 version 1.10 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.
