    The configuration variable was created by a plugin and the value is the default value provided by a plugin.

  - **TS\_MGMT\_SOURCE\_EXPLICIT**

    The value has been set in *records.config*. Note this value is returned even if the variable was explicitly set to the default value.

  - **TS\_MGMT\_SOURCE\_ENV**

    The value was retrieved from the process environment, overriding the default value.

## RETURN VALUES
