# Monitoring DFSMShsm status

This topic describes the workspaces that monitor the status of DFSMShsm™ activity. You access these workspaces through the DFSMShsm Status node in the Tivoli® Enterprise Portal.

See Workspaces for general information on predefined workspaces and a list of all nodes that are included in the Tivoli OMEGAMON XE for Storage on z/OS product. Each node corresponds to a specific area of storage resource monitoring. And each node includes links to a unique set of storage resource workspaces. See Accessing workspaces to learn about navigating among workspaces. And see Integration with other products to learn about linking to the workspaces of other IBM Tivoli Monitoring products.

## Navigating the workspaces of the DFSMShsm Status node

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.

## DFSMShsm Status workspace

This topic describes the main components of the principal workspace for this node.

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 Functions 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 data set requests and volume requests for that function and how many are active and how many waiting
  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 data sets. Each row displays:
    - The DD name of the data set
    - The number of extents for the data and index components
    - The percent of Available Space for the data and index components of the data set
    - The percent of Free Space for the data and index components of the data set
    - The total size of the data and the index components of the data set
  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
  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.
