Management¶

Retention rules¶

"Retention rules" gives you control on how long data is stored in your account. You might for example want to store measurements for 90 days, but delete alarms already after 10 days. By default, all historical data is deleted after 60 days (configurable in the system settings).

Retention rules are usually run during the night. When you edit a retention rule, you will not see an immediate effect in the Usage section on the Home screen of the Administration application.

Click "Retention rules" in the Management menu to view a list of retention rules configured for your account.

For each rule, the rule name, details on the data to be deleted (fragment type, type and source, see below) and the maximum age in days is provided.

The asterisk ("*") indicates that data with any value will be cleaned up.

Creating retention rules:

To add additional retention rules, click "Add rule" in the top menu bar.

1. Select the type of data to be cleaned up (alarms, measurements, events, operations, audit logs or all).
2. Enter a fragment type if you want to be more specific about the data to be cleaned up. To clean up all connection loss alarms with this rule, select "alarms" and enter "c8y_UnavailabilityAlarm" as property into the "Type" field.
3. If you want to remove data only from a specific device, enter the device ID into the "Source" field.
4. Enter the "Maximum age" in days (max. allowed value is 10 years in days).
5. Click "Save" to create the rule.

To delete a rule, hover over it and click the "Delete" button at the right.
