I honestly cannot remember how this was done on OEM 11g, been on OEM 12 since 2012 and then 13.2 for the past 3 years!
This is the default enterprise manager that we got with the database.
Database Version: Oracle 126.96.36.199 EE, RAC
As for the statement above, are you referring to the full fledged Grid Control product or Database Control?
Either way, perhaps the "Accessing Metrics Using the Grid Control Console" section from the documentation can set you on your way to finding the answer.
Hope this helps
Thanks for the reply. I will check the doc.
Can we add a collection schedule on OEM 13c?
You can find the navigation in 12c/13c releases as follow
Targets > Databases > [select target database link]
> Click on Database drop down menu > monitoring > Metric & Collection Settings > Other Collected Items
Search for 'Tablespaces' and verify its collection Schedule
We can see the status here, if its 'disabled' state, metrics were not showing in console for target database.
Click on disabled and select the 'Enabled' button to enable the metric, select the required collection frequency details
Click 'Continue' to save the changes
And from Target EM Agent side, below command will tell you the collection frequency as well.
/emctl status agent scheduler | grep -i tbsp
