Monitoring channel paths
This topic describes the workspaces that monitor the status of channel paths. You access these workspaces through the Channel Path node in the Tivoli® Enterprise Portal.
Channel Path workspace
This topic describes the main components of the principal workspace for this node.
The direct situation analysis feature is available for this workspace. The feature can help you analyze and understand a problem that is displayed in this workspace. See Directly monitoring situations.
- Views
- This workspace provides the following views. For a description
of the attributes used as column headings in the workspace table view,
review the attribute group definitions for this workspace in the online
help. The help resource includes attribute descriptions that are displayed
when you hover with the mouse pointer over a column heading.
- Channel path table view
- The table view displays one row of data for each channel path.
The view contains the following information:
- The channel path ID
- Its status
- Whether or not it is a shared path
- Utilization percentage across the complex
- Utilization percentage within this LPAR
- The type of connection it is
- Whether or not it is DCM managed
- The BUS utilization percentage
- Various read and write metrics for both the complex and the reporting LPAR
- The number of SMS volumes, NON-SMS volumes and the total number of volumes configured in the LPAR
- The channel path management facility group number for the path
- Complex % utilization bar graph
- This graph contains a bar for each channel path that had any utilization since the start of the RMF™ interval. The height of the bar indicates the percent to which the path was utilized in the complex.
- LPAR % utilization DASD bar graph
- This graph contains a bar for each channel path for which there are any volumes configured in the reporting LPAR and for which there was any utilization within the reporting LPAR since the beginning of the RMF interval.
- LPAR MB/Sec WRITE - DASD bar graph
- This graph contains a bar for each channel path for which there are any volumes configured in the reporting LPAR and for which there were any write operations that were performed to DASD in the reporting LPAR since the beginning of the RMF interval.
- LPAR MB/Sec READ - DASD bar graph
- This graph contains a bar for each channel path for which there are any volumes configured in the reporting LPAR and for which there were any read operations to DASD that were performed in the reporting LPAR since the beginning of the RMF interval.
