Function
The MONITOR GSTORAGE (monitor grande storage) command displays statistics on allocated storage and 1 MB pages.

Syntax

MONITOR GSTORAGE

Format

MONITOR GSTORAGE displays data in the following format:

NAME START SIZE (MB) 1M SIZE PGFIX

Where:

  • NAME - name of the memory object.

    Buffers are allocated in chunks and presented in one line using name "BUFFERS" and accumulated data for all chunks.

  • START - starting address of the memory object. For buffers it is the address of the first chunk.

  • SIZE (MB) - Size in MB of the memory object. For buffers it is the accumulated size of all chunks.

  • 1M SIZE - Size in MB of memory object backed by z/OS 1MB pages.

    For buffers some chunks may be backed by 1MB pages and some by 4K pages, so values in columns SIZE (MB) and 1M SIZE may be different.

  • PGFIX - a letter "Y" in this column indicates the storage is page fixed.

Usage notes

There are three statistical messages printed below the table, indicating the total amount of storage allocated above the bar, total amount of storage allocated with 1MB pages, and total amount of page fixed storage. All amounts are in MB. Data presented by the MONITOR GSTORAGE command represent current values.

Example

The following example shows output from a MONITOR GSTORAGE command, showing the amount of storage that could - and could not - be allocated above the bar and in 1MB pages:
