# Monitoring DFSMSrmm status

This topic describes the workspaces that monitor the status of DFSMSrmm™ resources. You access these workspaces through the DFSMSrmm 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 DFSMSrmm 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. See Accessing workspaces to learn more about navigating from workspace to workspace.

You access the primary workspaces of this node as follows:

1. Click the node in the Tivoli Enterprise Portal. The node is activated and the first workspace is displayed in the portal.
2. Right-click the node to display the pop-up menu.
3. Select the Workspace submenu to see a list of the available linked workspaces. These linked workspaces, in turn, link to many other, related workspaces as shown in Table 1

   Workspaces that are available in the "Workspaces" pop-up menu of the Navigator node:
   DFSMSrmm Location Summary | DFSMSrmm Error Summary
   DFSMSrmm Owner Summary | DFSMSrmm Pending Actions
   DFSMSrmm Account Summary | DFSMSrmm Configuration
   DFSMSrmm Job Summary |
   DFSMSrmm Program Summary |
   DFSMSrmm VRS Summary |

You start in the DFSMSrmm System Summary workspace to access all the other workspaces that are listed in Table 1. You can access the workspaces in this table using the standard path and method for navigating workspaces.
Note: The following italic phrase is repeated in Table 1: "DFSMSrmm Dataset Details workspaces are provided here." A set of standard workspaces is available where you see this phrase in the workspace hierarchy. The phrase includes a link to a description of the set of workspaces, which detail the volume, owner, VRS, and SMS construct of the relevant data set.

## DFSMSrmm System Summary workspace

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

When you click the DFSMSrmm Status node in the Navigator of the Tivoli Enterprise Portal, you see the DFSMSrmm System Summary workspace. The main components of the workspace are listed here.
Note: DFSMSrmm Data collection is turned off by default, so this workspace is initially empty. In addition, if your installation does not utilize DFSMSrmm, this workspace is always empty.

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.
  DFSMSrmm Control Dataset Space bar graph
    This graph contains bars whose height represents the percentage utilization of the Control Data Set data component and the Journal, as reported by DFSMSrmm.
  DFSMSrmm Pending Action Summary Volume Counts bar graph
    This graph contains bars representing the total number of volumes in each of the possible DFSMSrmm Pending Action states: Scratch, Replace, Return, Init, Erase and Notify.
  DFSMSrmm Volume Type Distribution Summary pie graph
    This graph shows the number of non-scratch volumes of each type: Master, User, Init and Entry.
  DFSMSrmm Volume Utilization Summary bar graph
    This graph contains shows the distribution of volumes based on their percentage utilization. The height of each bar represents the number of volumes in that utilization range (for example, utilization between 21% and 30%).
  DFSMSrmm System Summary Total table view
    This table contains a single row that summarizes the entire DFSMSrmm environment and contains the following attributes. Notice that many of these same attributes are shown on the linked-to Summary workspaces described below. In those cases the attribute values are relative to the specific object that you are summarizing (for example, a location, an owner, a creating job, and so on). The attribute values are not relative to the entire DFSMSrmm environment:
    - Collection Status - whether a DFSMSrmm collection cycle has been run, if it ran to completion or was stopped, and so on.
    - Summary Collection Start Time - the time that the last collection cycle started. All summary data displayed on this and other summary workspaces is based on the contents of the DFSMSrmm CDS between the indicated Collection Start and End times
    - Summary Collection End Time
    - Total Volumes - the total number of volumes found in the CDS
    - Total Datasets - the total number of data sets contained on all volumes
    - Physical Volumes - the number of volumes that are neither Logical nor Stacked
    - Scratch Volumes
    - Master Volumes
    - User Volumes
    - Init Volumes
    - Entry Volumes
    - New Scratch Volumes - the number of volumes returned to scratch status during or since the last DFSMSrmm expiration processing
    - Total Errors - the total number of temporary and permanent read and write errors on all volumes
    - Total Permanent Errors
    - Total Temporary Errors
  DFSMSrmm System Usage and Activity Summary table view
    This table contains a single row that summarizes the entire DFSMSrmm environment, and contains the following attributes. Some of these attributes can be calculated only when you have selected the Summarize RMM Dataset Attributes option in the RMM Collection Control dialog box. Notice that many of these same attributes are shown on the linked-to Summary workspaces described below. In those cases the attribute values are relative to the specific object that you are summarizing (for example, a location, an owner, a creating job, and so on). The attribute values are not relative to the entire DFSMSrmm environment:
    - Total Capacity - capacity of all volumes, in gigabytes
    - Total Usage - the total usage on all volumes, in gigabytes
    - Average Volume Utilization - average utilization across all volumes, expressed as percentage
    - Average Compression Ratio - calculated percentage compression achieved between the data written by the application and the data recorded on the tape media
    - Average Volume Use Count - average number of times each volume was read or written
    - Volumes R/W Previous Day - the number of volumes that were read or written on the previous Julian day
    - % Volumes R/W Previous Day - the percentage of the total volumes that were read or written on the previous Julian day
    - Average Datasets per Volumes - the average number of data sets contained on each tape volume
    - Average Dataset Size - the average size of a data set, in megabytes to 1 decimal place
    - Datasets R/W Previous Day - the number of data sets that were read or written on the previous Julian day
    - Datasets Created Previous Day - the number of data sets that were created on the previous Julian day
    - Data Created Previous Day - the amount of data that was created on the previous Julian day in all newly created data sets, expressed as megabytes to 1 decimal place
