Title
Topology location for DB2 total used tablespace size in megabytes over time -
Description
A DB2 database is on autogrowth so utilization will always be at 100%. Where can users find the historical growth in total used tablespace size in megabytes in the topology?
-
Cause
The DB2 storage area page displays the total utilization chart as a percentage rather than actual megabytes used. For an autogrowth database, once the database has reached its initial size it will remain at 99% as the database autogrows. -
Resolution
To examine the raw data we accessed the topology history located here from the Foglight console.
Configuration | Data | DB2_Data_Model | Instances | {Instance Name} | Table Spaces | {Tablespace Name} | Tablespace Used Size MB | History
This information was then added to a custom report.
