The CCSS performance and status monitoring solution, QSystem Monitor, includes features that can be leveraged to monitor independent auxiliary storage pools (known as IASPs).
QSystem Monitor offers you:
The following sections describe these capabilities in more detail.
The ASP view in the Online Monitor is a good starting point (see image below). It allows you to check the following information about your IASPs:
The ASP view also includes the following WRKDSKSTS-style information for the physical disks that comprise the IASP:
The following monitor types are available for independent ASPs:
Following is an example of a Standard Group view of available ASP volumetric definitions:
Following is an example of a Standard Group view of the ASP status definition:
There is also the Disk I/O monitor type that provides a job-level breakdown of disk activity, if required. The Disk I/O definition shows the available parameters that are used to provide a list of monitored jobs.
Details on the disk I/O can be displayed:
The Disk Data Collection (overnight and real-time), Summarization, Audit Reporting and display programs have been changed to include the ASP name and treat it as part of the library name; it will in effect become a qualified name for the library.
Disk Collection: Application definition has been changed to allow for IASP names.
MONDSKINQ has been changed to allow inquiry by IASP and the display of IASP information.
The Disk Audit report has been changed to report by IASP.
Disk Summary: Displayed library names are qualified when IASPs exist for the system. The user will be able to display data for a selected IASP or data at the *ALL level.
Report Generator: The report Generator will need to store the IASP list for disk summary entries.
Online Monitor: A new IASP parameter has been added to the definitions.
Figures 1-4 show IASP-related object and library data in the Online Monitor module:

The disk collection routines collect IASP data for review. Figures 5-7 show that type of data in the Disk Usage Inquiry (MONDSKINQ):

The disk collection routines capture IASP data for review. Figures 8-11 show that type of data in the Disk Summary module:

The following table contains a list of ASP-related messages which QSystem Monitor generates under the conditions described in the message text. These apply to independent ASPs as well as system ASPs.
