Monitoring DFSMShsm status

This section summarizes the workspace links that are available through the Navigator node. Depending on your monitoring goal, you follow a specific series of links to get detailed information about storage resources.

You start in the DFSMShsm Status node to navigate to the workspaces that you see in Table 1. You can access the workspaces in this table using the standard path and method for navigating workspaces.

When you click the DFSMShsm Status node in the Navigator of the Tivoli Enterprise Portal, you see the DFSMShsm Status workspace. This workspace monitors DFSMShsm activity for the entire HSM subsystem, including utilization of volumes and CDS space. The main components of the workspace are as follows:

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.

DFSMShsm Function Status Report

The tabular report in the top-center portion of this workspace contains one row for each DFSMShsm function. Each row displays:

• The status of that function for the reporting LPAR
• The number of dataset requests and volume requests for that function and how many are active and how many waiting
• The name of the HSMplex and the base name of the CRQplex that the HSM Host is a member of, or n/a, if the host is not a member of a CRQplex

DFSMShsm Control Dataset Report

The tabular report covering the entire width of the workspace in the vertical center contains one row for each of the DFSMShsm control datasets. Each row displays:

• The DD name of the dataset
• The number of extents for the data and index components
• The percent of Available Space for the data and index components of the dataset
• The percent of Free Space for the data and index components of the dataset
• The total size of the data and the index components of the dataset

DFSMShsm Status Report

The tabular report covering the entire width of the workspace at the bottom of the screen contains a single row of data describing DFSMShsm status in the reporting LPAR. This row indicates:

• Whether DFSMShsm is active
• The address space ID
• The version of DFHSM
• DFSMShsm start time
• The interval start time
• The number of DFSMShsm requests during this collection interval
• The CPU usage during this interval
• The number of requests that abended during this interval
• The number of volume migrations, backups and the number of migration and backup volumes recycled during this interval
• The name of the HSMplex and an indication of whether at least one HSM host on the z/OS® image is in a CRQplex

Waiting requests bar graph

This graph contains one bar for each DFSMShsm function which has at least one waiting request. The height of the bar indicates the total number of waiting requests for this function.
