All of the system-level workspaces, except the Address Space Bottlenecks workspace, and all of the sysplex-level workspaces, except the Users Data for CF Structure and GRS Ring Systems Data for Sysplex workspaces, can record and report historical data.
Workspace views that have history recording enabled have the
history icon in the upper left corner.
For historical data to be available, historical data collection must be configured and enabled on all Tivoli Enterprise Monitoring Server in a sysplex. (Because the identity of sysplex proxy monitoring server can vary, the Tivoli Enterprise Portal cannot know which address space is currently serving as the proxy.)
For information on configuring Tivoli OMEGAMON XE on z/OS data storage, see the IBM Tivoli OMEGAMON XE on z/OS: Configuration Guide.
For information on configuring and reporting of historical data collection with the Tivoli Enterprise Portal, see the topics Historical Reporting Overview, Historical Reporting, and Configure History Data Collection in the online Help, and OMEGAMON XE on z/OS: User's Guide.
