Purpose

To Monitor CSM Storage usage:

Using the DISPLAY CSM command, you can monitor the use of storage managed by the communications storage manager (CSM). You can use this command to determine how much CSM storage is in use for ECSA and data space storage pools. This command also provides information about specific applications that are using CSM-managed storage pools. This command is routed to CSM so that VTAM® does not have to be operational when you issue this command.

To display the status of CSM Monitor:

Using the DISPLAY CSM command with MONITOR option, you can display the status of CSM buffer monitor.

Operands

To Monitor CSM Storage usage:
OWNERID
Specifies whether to display information about the amount of storage owned by all owners or a specific owner. The owner ID is the halfword address space identifier (ASID) of a CSM buffer owner. ASID values are in hexadecimal format and range from 1 – 7FFF. If OWNERID is not specified, this command displays the total storage allocated to the pool by storage pool source.
OWNERID=ALL
Produces a display by each owner ID showing the amount of storage owned in each storage pool and the cumulative total for each owner ID across all pools.
Note: The sum of the total of the storage allocated to all users of a particular pool may be greater than the total amount of storage allocated to that pool. This is because of the existence of multiple instances of a buffer created when an application program issues the IVTCSM ASSIGN_BUFFER macro. The storage displayed for each OWNERID indicates the amount of storage that must be freed by the user to enable the storage to be returned to the buffer pool.
OWNERID=ownerid
Specifies that the storage owned by the specified owner ID be displayed. The cumulative total across all pools is also displayed.
To display the status of CSM Monitor option:
MONITOR
Displays the status of CSM Monitoring of CSM storage usage.

Resulting display

The resulting display for monitoring CSM storage usage shows the following information:
  • If the OWNERID operand is specified, the amount of storage allocated to the owner
  • If the value OWNERID=ALL is specified, the cumulative storage allocated to each user across all pools
  • If the OWNERID is not specified:
    • The highest level of fixed storage obtained since the last DISPLAY CSM command was issued without the OWNERID operand specified
    • The highest level of fixed storage obtained since the last IPL
    • The highest level of ECSA obtained since the last DISPLAY CSM command was issued without the OWNERID operand specified
    • The highest level of ECSA obtained since the last IPL
    • The names of the CSM data spaces
    • Information about storage usage for each buffer pool
    • The overall storage use for each of the different sizes in the ECSA pools
    • The overall storage use for each of the different sizes in the data space pools
    • The maximum amount of fixed and ECSA storage that can be allocated by CSM, and current values for fixed and ECSA storage

Storage amounts are displayed in units of K (kilobytes) or M (megabytes).
