In Configuration > My System go to the 'ODW' tab:
If you have a subscription that contains ODW, then you will see this tab. Within this section you can choose to enable ODW imports, i.e. store data longer than the seven-day retention period allowed within the runtime database. ODW data is stored in summarized one-hour blocks that ensure all service check state changes are recorded and can be reported on.
After enabling ODW imports, you can change the retention period of ODW data.
You can also enable 'Extended Import'. If you enable this, Opsview Monitor stores every service check result and performance plot for the
Extended Import retention period. Enabling Extended Import can greatly increase the size of your ODW and slows down both the
import_runtime process and generating reports. Extended Import data is only used by the
Daily Performance Report; if you do not use this report, or do not use a custom report that uses the
odw.performance_data tables, you likely do not need to enable Extended Import.
Finally, you can choose to import all Hosts/All Service Checks, or uncheck the box to choose to store long term data about a specific set of Hosts/Service Checks as shown below:
