Troubleshooting data collection

Collecting data is crucial for monitoring OMEGAMON® for Storage performance. Use the workarounds to troubleshoot issues that you might face during data collection.

DFSMShsm space-size values exceeded
You can increase the value of the DFSMShsm space-size when the default values are too low in some systems.
Workspace displays no data or does not show all the data you expected
You have clicked on a navigation item or you have clicked on a link and the workspace either displays no data or does not show all the data that you are expecting.
Tape collection off, no VTS data occurs
Sometimes the VTS workspace do not display any data when you do not complete the prerequisites for enabling the collection of VTS data.
The timing of tape refreshes is in minutes, but data only changes hourly
A known issue for tape collection data is though you have specified a interval, the new data is available only after the one-hour interval.
Monitoring agent is running out of storage
If response time is slow on the monitoring agent, check the RKLVLOG for messages about a possible storage problem. A storage usage event is generated every hour and written to the RKLVLOG. This behavior is driven by a scheduling command in RKANCMDU member KDSSTART.
Long-term historical data reports
This section provides troubleshooting information regarding the generation of historical (long-term) data reports.
