This feature collects and reports spool usage by session. This information is reported in MONITOR SESSION PM/API, and reported in MonitorMySessions and MonitorSession Open APIs, in the following columns: ReqHotAmpSpool and ReqHotAmpSpoolId. ReqHotAmpSpool stores the spool value of the highest utilized AMP and ReqHotAmpSpoolId provides the Vproc ID of the highest spool utilized AMP for the current request.
- This feature allows users to track skewed spool usage by session.
- This feature provides the ability to identify the highest shared spool usage for proxy users in trusted sessions.
- Use this feature from Viewpoint or from a custom PM/API application, or use Open APIs for ad hoc queries.
- For MONITOR SESSION PM/API requests, you must use monitor software version 13 to report the data described in this feature.
