You can monitor the performance of your SAP spool system in the context of the SAP monitoring architecture. The Spool Monitor provides you with a tool with which you can obtain an overview of the system status quickly and can react to alert messages.
1. Start the Spool Monitor by calling transaction RZ20. ON the CCMS Monitor Sets screen, expand the SAP CCMS Monitor Templates monitor set, and start the Spool System monitor by double clicking it. The system displays a monitoring tree you can expand to display the information you require.

The spool monitoring tree consists of the subtrees System Wide and Spool Servers. The System Wide subtree contains information about the current utilization of the number range for the spool numbers.
Note:
• SpoolNumbers – Spool number that is assigned to every output request
• UsedNumbers – Usage of the spool numbers as a percentage; you must delete old output requests before this number reaches 100 percent
