- Temp Directory: This gives information of the temporary files. When you click on 3 dots, you can see the details of the temporary files. There are options to delete the files in the Temp Directory and also refresh the temp directory status.
- Cache: This is the status of the application cache. One can see how many resources are present in the cache. You can also delete all the resources in cache. It is possible to configure the entire application level cache by making changes in cache.xml file as well as individual report level cache can also be defined.
- Cached Reports: This shows how many reports are present in the cache. A list of reports can be seen on clicking the 3 dots. You can delete the reports and also refresh the status.
- Cached Data sources: This card shows how many data sources are available in the cache. When user clicks on the details button (3 dots), a list of all the data sources and their type, connection ID, and Cache Status are shown. There are 4 types of Cache Status:
- Data Source: As soon as the data source connection is created, the catalogs, schema and tables inside the database are added to the cache. This status is shown as Datasource.
- Partial: When a metadata with a few tables and columns is created, those tables and columns are added to the cache. This status is shown as Partial.
- Full: When all the tables and columns of a particular data source are added to the cache (using single or multiple metadata), it is shown as Full.
- Connection: If the Refresh button on the cached datasources card is clicked, then all the details are erased from the cache. If a user loads a report of a data source that is not present in the cache, the data source connection is present in the cache. However, the metadata and associated tables and columns are not present. Hence, this status is Connection.

This tab gives a list of all the reports that have been scheduled. You can pause, stop or delete a particular schedule. Please note that any schedule deleted from this page will restart on application server restart.
The plugin tab gives a list of data source drivers that are present in the Drivers folder of hi-repository. User can delete the driver that is not required. Whenever a driver is added from the data sources page, it gets added to this list as well. Similarly, if the driver is deleted from the plugins list, it gets removed from the datasources tab and the green tick mark against that particular database icon will be removed.
This tab is used to configure the middleware for the use of NoSQL database and flat files. Please refer this blog to understand how to configure middleware.
