Monitor Data Storage and Manage Capacity Usage

As an administrator, you can monitor the data storage for your Oracle IoT Intelligent Applications Cloud Service. Use the Data Storage page to review storage data in the system, to set up or adjust the time window for data retention, and to run data deletion jobs.

When you log in to your IoT application as an administrator, a notification appears with details on the storage capacity used. Notifications may also appear periodically for every 10% of capacity that is used up. High-priority notifications are sent after you have used up more than half of the storage capacity. You can use the Data Storage page to manage your storage capacity.

The Data Storage option under App Settings lets you monitor and manage the data storage for your application. The Data Storage page has the following sections:
  • Summary: Shows you the total data storage capacity available for your account, and the currently used up capacity. Depending on your current usage, the status is indicated using one of the following colors:
    • Green: Indicates that more than 50% of the available capacity remains.
    • Orange: Indicates that between 25% and 50% of the available capacity remains. A recommendation on ways to manage your data is also included.
    • Red: Indicates that less than 25% of the available capacity remains, and you must take steps to manage your storage data.

    Data Storage Summary Section (described in text)

  • Data Management: Lets you manage data, change settings, and create data deletion jobs. The data capacity usage percentages are shown category-wise:
    • Device Data: Comprises sensor data, application messages, log messages, and other device related data.
    • Metric Data: Comprises data specific to metrics or KPIs.
    • Training Data: Comprises training data, such as training models and scoring information for your analytics artifacts.

    You can select the data life span for each category. The data life span is the time period for which data is retained. By default, past data is never deleted, and data is retained forever for each of the data types.

    You can choose to create data deletion jobs to delete selective data. A data deletion job lets you select the data type and time span for which you wish to delete data.
