img Device-to-Cloud (D2C) message policy allows you to transform default payload to your desired payload schema via the jq filter. For additional information, refer to https://stedolan.github.io/jq/manual/.

Store and Forward​

D2C messages can be cached in a specified location and sent to the cloud later. This feature will help you store the acquired data temporarily in a queue when the network between your IIoT Gateway and the cloud is disconnected and transmit the data to its destination after reconnecting. To enable the function, click on the Store and Forward and select Enable Store and Forward. You can select a target disk and set a maximum storage cache, set a retention policy, and a TTL (Time to Live) value for the messages.
