About
An alert is a agent with as destination the dashboard of the user.
Storage
The results of Alerts are stored in the user's directory, inside the folders _deliver and _deliveries.
root/users/userLogin/_delivers/_deliveries
As a result, the catalog directory can have a huge size if the user forget to suppress them.
There is no function to suppress them automatically. And an enhancement was rejected ABILITY FOR BI ADMIN TO DELETE ALL AGENT OBJECTS FROM USERS /_DELIVERS FOLDERS.
